What is cheaper flat roof or pitched. Which roof is cheaper pitched or flat

One of the most important parts of the house is the roof - warmth and comfort, noise level and frequency of building repairs depend on its quality.

Naturally, during development planning, the question arises, which type of roof to choose, or which roof is better - cheaper, more expensive, broken or gable, or maybe four-slope?

It is not enough that the roof is just strong and attractive. It must also have a number of important properties: to provide good protection from rain and snow, protect from heat and cold, be fireproof. Let's look at the main types of roofs and their characteristic features, because the choice of material for the roof depends on the type of roof.

Main types of roofs

flat roofs. They are usually erected over outbuildings and outbuildings, garages, bathhouses, sheds, as well as houses with a terrace on the roof.
pitched roofs. This type of roof is more widespread, and there are several classifications. pitched roofs, one of which we present below. Among other things, pitched roofs can be divided into warm and cold, with and without an attic.

We list the main structural varieties of pitched roofs.

Shed roofs
Their surface is a plane resting on opposite walls. different heights, i.e. is at an angle to the horizon.

gable roofs
They consist of two angled planes and rest on opposite walls of the same height. Perhaps this is the most common type of pitched roofs.

broken roofs
A type of gable roof, in which each of the slopes consists of two located under obtuse angle rectangles.

cruciform roofs
They are a combination of several ordinary gable roofs, as if cut into each other at a right angle.

hip roofs
This hipped roofs with two long trapezoidal slopes and two short triangular.

Half hip roofs
A type of hip roof, sometimes called a Dutch one, in which the end slopes do not reach the eaves. Thanks to this design, the house can withstand the wind better, and its gables are less exposed to precipitation.

hipped roofs
A kind of 4-pitched roof, consisting of four equal slopes of a triangular shape.

When choosing the type of roof, one should take into account not only its intended operational properties, but also decorative qualities. In low-rise buildings, the roof has a large relative volume and its appearance largely determines the architectural solution.

In private houses, mainly roofs of high structures are erected. This allows you to build an attic, and the house takes on a more presentable appearance. Also, steep slopes do not allow water and snow to linger on the roof. In areas with strong winds it is preferable to build low roofs or high ones, with additionally reinforced truss systems.

You should also consider what kind of roof the developer can afford. Naturally, the roofs are more simple designs cheaper, and the most economical options are flat and pitched roofs. Additional Convenience pitched roof in that it allows you to increase the internal volume of the building, and in outbuildings at the same time serve as a ceiling.

If the attic will be used for household needs, it is better to build gable roof. In areas with strong winds, a type of hip roof is the best choice, but its construction will be expensive. In addition, the construction of hip roofs requires high professionalism, and should only be trusted by experienced craftsmen.

In houses of complex shape, as a rule, cruciform roofs are used. This is a rather complex structure, consisting of many intersecting slopes. The complexity of the cruciform roof is to ensure tightness internal corners roofs. Such roofs are expensive, they must be erected experienced craftsmen and made of quality materials.

Roof construction elements

After choosing the type of roof, you can begin the selection of materials. Therefore, let's get acquainted with the main structural elements roofs:

Basic structure. Its type depends on the type of roof. Usually it is constructed from wooden beams and rafters.
Roof base. It can be built in the form of a lattice or be solid.
Hydro- and heat-insulating layers.
Roofing material.

Rafters and their types

Rafters perform an important function in roof construction. This is a support for the crate, which takes on not only the weight of the roof, but also the wind load, as well as the pressure of snow.

hanging used for long spans;
oblique, used for spans up to 6.5 m. With additional support, the spans can be extended up to 12 m.

The design and construction of truss systems is work that requires great skill. Its quality determines the bearing capacity and, consequently, the strength of the roof.

Foundations for roofing

The type of base under the roof is selected depending on the intended roofing material.

There are two main types of base under the roof:

crate(used for roofing made of metal tiles, slate or metal profile)
continuous flooring(using roll materials)

Solid flooring is constructed from two layers of boards. The first layer is called working, and the second - protective. The latter is located at an angle of 45 degrees with respect to the worker and is constructed from narrow boards. Between these layers, a windproof material is placed, usually roofing material RRP-300 or 350.

When installing the crate, a number of rules are observed:

all elements of the crate are securely fastened to the rafters;
their joints are located on the rafters in a run;
the distances between them must be maintained over the entire surface of the roof being constructed.

Roofing materials and works

The top part of the roof is called the roof. It is in direct contact with the external environment, taking on all the power of wind and precipitation. Therefore, the main qualities that it must possess are strength and water resistance.

There are many materials for roofing, and choosing one of them, you should consider it. performance characteristics, as well as a number of other factors:

climate;
functional purpose of the building;
material durability;
material cost;
its soundproofing and heat-saving properties;
the complexity and cost of roof maintenance;
external attractiveness of the material.

It is difficult to give unambiguous and comprehensive advice on the choice of roofing material, which will be better, since all of the above factors influence it, and, as you know, ideal building materials do not exist. In addition, the determining criteria may differ, for example, with insufficient funding, price becomes the main one, and all other factors are considered less captiously. On the contrary, if consumer properties come to the fore, then the price, as a rule, does not have a decisive value. For someone, perhaps, beauty or color will be the main factor, since according to the owners' plan, the house should not be like the rest.

The choice of material should be made at the stage of creating a house project, since the type of roof construction depends on it, and it will be difficult and expensive to make changes to the finished project.

conclusions

The selection of a roof structure and roofing material is an important stage in the construction of a house. Finding the best solution can only be done by taking into account a number of factors:

purpose of the building;
noise-insulating and heat-saving characteristics of the roof;
construction budget;
climate features;
aesthetic impression.

Only by taking into account the listed factors and weighing each of them, you can choose best option roofs and type of roofing material.

Starting the construction of a private house or cottage, every developer wants to know which roof is better and be sure of its reliability. One of the main factors that affect these parameters is the roof of the house, which must comply with design feature and the general architecture of the building, as well as the material used for the roof.

The pitched roof of the house is the most common in the Russian region, because. it snows well.

During the construction of private houses, various types of roofs are used, which differ in the number of slopes, their angle of inclination, and the possibility of building an attic.

The main elements of the roof

Rafters - a building structure of special beams located in a certain way. Rafters are designed to support the roof and uniform distribution roof loads on all bearing walls Houses.
Sheathing - a flooring made of boards laid and fixed to the rafters, which is the basis on which the roofing material is laid. Depending on the roofing material used, the lathing may be sparse ( individual boards are fixed at some distance from each other) or solid (the boards of the crate are fixed without gaps).
Roofing is a coating material that is laid directly on the crate. Roofing material is selected depending on the financial condition and desire of the developer.
The ridge is the junction of the roof slopes.

Advantages and disadvantages

There are a large number of different roof options that are used in modern low-rise construction. They have a different configuration, their advantages and disadvantages, the material used.

Flat roof. This design does not have any bias. In the construction of an individual house, it is practically not used, since a flat surface keeps precipitation on its plane. These factors lead to the fact that the roof is quickly destroyed, resulting in roof leaks.

shed roof

In this embodiment, it is assumed that one inclined surface (ramp) is arranged over the entire area of \u200b\u200bthe house. Such a roof rests on two load-bearing walls having different heights. This type is not particularly popular among private construction. Most often used in the construction of garages or utility rooms. According to their design, they can be ventilated and non-ventilated. Ventilated roofs have a slope of 5-20 degrees, and non-ventilated 1-5 degrees.

Benefits of a shed roof

The scheme for calculating the angle of the roof.

Simplicity of design, which does not require special calculations of the truss system, slope angle and load calculation. Possibility of installation by people without special knowledge and skills.
Ease and speed of the device, repair during operation. No complex truss systems.
Due to the absence of stressed elements, reduced wear of the elements.
Low installation cost.

Disadvantages of a pitched roof

A small under-roof space, which excludes the possibility of an attic or attic space.
The impossibility of a device of full thermal insulation.
With a strong wind blowing from a high side, a sharp decrease in reliability.
With a slight slope, the need for regular snow removal from the roof surface.

gable roof

This option consists of two equal opposite slopes, which on one side rest on the load-bearing walls of the house, and the other two are connected in the ridge. The plane (wall) that forms between two slopes is called a pediment. The pediment can be made both with an opening for a window, which is used to illuminate the attic space, or solid. Beautiful attic windows make the whole building light and airy. This type of roof is the most popular and common in individual construction. As a rule, such roofs are made in houses that do not differ in particular architectural sophistication.

The gable roof has an attractive appearance and is very practical. For the roof, any material intended for these purposes can be used. A refined look to the house can give decorative trim gables.

When building a gable roof, it is necessary to take into account the own weight of the structural elements, as well as the additional load from snow and rainwater.

Benefits of a gable roof

Types of truss systems for single-pitched and gable roofs.

Practicality of use. With sufficient under-roof space, an attic or a full-fledged attic space for household needs is allowed. In such cases, the most rational would be the construction of a "broken" shape. The plane of the slopes from the ridge has a slight slope, which at a certain level turns into more sharp corner tilt.
Possibility of installation in the attic of heating, ventilation and air conditioning systems.
Efficient removal of snow and water from roof planes.
The construction of a gable roof does not require complex technological solutions.
Attractive appearance. During construction, you can choose the option both with the same slope angles and slope areas, and with different ones.
If necessary, repairs do not require significant costs.
Only a shed roof is cheaper.

Disadvantages of a gable roof

The dependence of the height of the roof and the angle of inclination of the slopes on the size of the house. The larger the area of \u200b\u200bthe house, the more material will be required to construct such a roof.
When installing an attic, it becomes necessary to increase the height of the structure, increase the number and strengthen the load-bearing elements (rafters), which in turn increases the cost of construction.
If there is an attic, dormer windows are required, the more windows for the attic, the more difficult the design of the gable roof becomes.

hipped roof

This type of roof consists of two slopes, which are triangular in shape, and two trapezoidal slopes. When building a hipped roof, there is no need for gables. Attic windows are used to illuminate the attic, which are mounted directly on the roof slopes. Such a roof also has another name - hip, since the slopes of a triangular shape are called hips. If the roof consists of four equal slopes, connecting at one point, then this type of roof is called hipped roof. Such roofs are most often arranged in areas with a mild climate.

Benefits of a pitched roof

With a decrease in the lower size of the hip, it becomes possible to make the attic space more functional. The option of an attic device is not excluded.
Houses with such roofs have a rather attractive and original look, which can be made unique by choosing the appropriate roofing materials.
Increased strength and reliability of the design.
High resistance to external loads in the form of strong wind, snow and rain.
Uniform heating of the attic space from all sides, which helps to maintain a comfortable temperature regime.

Disadvantages of a pitched roof

The roof in the form of an envelope is difficult to implement, but it looks spectacular.

The complexity of the construction, which requires certain engineering calculations.
A large area of \u200b\u200bthe slopes, and, accordingly, a greater weight of the structures.
When building a pitched roof in areas with a cold climate, it is necessary to use special insulating materials, which increases the overall cost of construction.
For the installation of a hipped roof, the services of qualified craftsmen are required.
Increase in cost when installing an attic, as construction is required additional walls for the perimeter of the attic, as well as the installation of windows directly in the roof.

Multi-gable roof

It is an original, complex architectural design, which may include a different number of slopes. Such a roof is most often mounted in houses that have several levels, attics, attics, various extensions, etc. When constructing a multi-gable roof, sunken long angles are obtained between the slopes, called "grooves" or "valleys".

The process of erecting a roof of this type is very laborious and lengthy. When planning the construction of a multi-gable roof, even the most daring design ideas can be realized.

Benefits of a multi-gable roof

The unique appearance of the house, beauty and grace.
Possibility of application on structures of complex architectural form.
Increased living space due to the construction of the attic.

Disadvantages of a multi-gable roof

Availability a large number complex structural elements, ribs and internal corners.
Expensive and labor intensive construction. The consumption of materials is approximately 4-5 times greater than with other types of roofs. This is due to the large amount of waste.
The complexity of design and calculation work.
The roof may experience additional load from snow between the slopes at the inner corners.
Quite a complex water drainage system.

spire roof

This version of the roof consists of a certain number of triangular slopes, connected at one point and mounted at an acute angle. Spire-shaped roofs are used in cases where the project provides for the construction of towers. Such a roof is bright decision to create a unique look of a house under construction. Very often, such towers, if the area allows, are used for arranging living rooms.

Roof spire diagram. All sides of the roof spire must be the same.

Benefits of a spire roof

Unique and attractive appearance.
Due to the fact that there is an acute angle of inclination, no side events for snow removal.

Spike roof disadvantages

Complexity and duration of construction.
The need for calculation work.
The need to attract qualified craftsmen.
The impossibility of an attic device.

All presented options are considered fundamental. Each type is well complemented with various details that can decorate the look of the house. But before choosing an acceptable option, it is necessary to take into account factors such as physical and climatic conditions, as well as the performance indicators that characterize the roof.

For areas with heavy snowfall, it is recommended to choose structures with a large slope angle, the roof will be protected from rapid damage, and the attic from leaks, which will extend the life of the entire structure.

Main types of materials

Regardless of which type of roof is chosen, whether there are attics or not, the roof and the material used for this purpose play the main role in reliability.

The main materials for reliable protection houses from adverse weather conditions are:

material based on minerals and ceramics (natural slate, ardogress, etc.);
bitumen-based material (roofing material, shingglass, fiberglass or fiberglass impregnated with a modified mixture);
metal material (metal tiles, galvanized profiled sheets with polymer coated and without it, roofing made of sheet copper or aluminum);
cement-based material (asbestos-cement corrugated sheets, cement-sand tiles)
material on polymer base(polycarbonate, etc.)

According to the form of execution, roofing materials are divided into:

Roof made of various types materials has its advantages and disadvantages, so the choice depends on the desire of the developer and his capabilities.

Determining which roof and roofing is cheaper, as well as making the choice of roof structure is a crucial moment, since the comfort of living and the duration of operation of the entire structure depend on it.

Which roof is better and cheaper for a country house, cottage or cottage

One of the most important parts of the house is the roof - warmth and comfort, noise level and frequency of building repairs depend on its quality.

Naturally, during development planning, the question arises, which type of roof to choose, or which roof is better - cheaper, more expensive, broken or gable, or maybe four-slope?

It is not enough that the roof is just strong and attractive. It must also have a number of important properties: provide good protection from rain and snow, protect from heat and cold, and be fireproof. Let's look at the main types of roofs and their characteristic features, because the choice of material for the roof depends on the type of roof.

flat roofs. They are usually erected over outbuildings and outbuildings, garages, bathhouses, sheds, as well as houses with a terrace on the roof.
pitched roofs. This type of roof is more common, and there are several classifications of pitched roofs, one of which we will give below. Among other things, pitched roofs can be divided into warm and cold, with and without an attic.

Classification of pitched roofs

We list the main structural varieties of pitched roofs.

Their surface is a plane resting on opposite walls of different heights, i.e. is at an angle to the horizon.

They consist of two angled planes and rest on opposite walls of the same height. Perhaps this is the most common type of pitched roofs.

A type of gable roof, in which each of the slopes consists of two rectangles located at an obtuse angle.

They are a combination of several ordinary gable roofs, as if cut into each other at a right angle.

These are hipped roofs with two long trapezoidal slopes and two short triangular ones.

A type of hip roof, sometimes called a Dutch one, in which the end slopes do not reach the eaves. Thanks to this design, the house can withstand the wind better, and its gables are less exposed to precipitation.

A kind of 4-pitched roof, consisting of four equal slopes of a triangular shape.

In addition, the construction of hip roofs requires high professionalism, and should only be trusted by experienced craftsmen.

In houses of complex shape, as a rule, cruciform roofs are used. This is a rather complex structure, consisting of many intersecting slopes. The complexity of the device of the cruciform roof is to ensure the tightness of the inner corners of the roof. Such roofs are expensive, they must be built by experienced craftsmen and always from high-quality materials.

Which roof is better and cheaper for a country house, cottage or cottage - My Life

Which roof is better and cheaper for a country house, cottage or cottage One of the most important parts of the house is the roof - its quality determines the warmth and comfort, the noise level and the frequency of building repairs.

Which roof is cheaper

One of the most important parts of a house is the roof, because the service life of the entire constructed building will depend on its strength and durability of the selected roofing material. That is why you need to be very careful about the choice of coverage. For some it will be the most important question which roof is cheaper, while for others the aesthetic side of the roof or the value for money will be more important.

In order to determine the choice of roof, you need to know the features and properties of different types of roofing. The roof must have thermal insulation properties, provide protection from weather and moisture, and maintain fire safety standards.

Roofs are divided into two types - pitched and flat.

Pitched roofs can be cold and warm, have an attic or not. In private construction, attic-type pitched roofs are usually used, because. this type of roof is easiest to remake for arranging additional living rooms or storage. Flat roofs are used for sheds, garages or other outbuildings. Even in a residential building, you can make a roof, on top of which you can arrange a comfortable terrace.

How to choose a roof

In order to choose the right type of roof for your home, you need to consider not only which roof is cheaper, but also the weather conditions in the area where the house is located.

It should be noted that for areas where there are heavy snowfalls great solution will be normal gable roof, because it is the best at removing sediment. Flatter roofs need to be made in windy areas, they have a small windage.

Basically, people prefer pitched roofs, because. they allow the house to look more solid, proportional, and most importantly - it is possible to make an attic floor. To perform such a roof, it is better to involve specialists, because this work is quite complicated and needs a certain accuracy to ensure reliability. This type of roof will exert minimal pressure on the floors.

If the price-quality ratio is more important to you, then it is better to make a flat or shed roof, because they are easier and cheaper to install.

How to choose material

How the material will be spent will depend on the design of the roof. However, it is worth saying that approximately the same amount of materials will be required to complete a gable and single-pitched roof, so it will be more difficult to say which roof is cheaper.

To start choosing a material for a roof, you should know the design of the roof. Its main components are:

1. The basis of the structure - beams, trusses and rafters;

2. Base - crate or solid;

3. Insulation or insulator;

4. Roofing.

Rafters and trusses are the main frame for the roof. They should be carefully chosen, it is best done by professionals. The rafters will take on the entire load and distribute it over the structures below: supports and walls. If you make it more massive and heavy roof structure, then the entire frame will be more expensive than if it is performed for a soft coating. The base for the roof is always made depending on the coating used. If soft or roll coating, then it is best to make a solid base.

If you use a metal tile or just a tile, then you can also make a mesh base. Which coating is better, everyone will choose according to their needs: aesthetic appearance, durability and strength, water resistance and thermal insulation, and most importantly, financial opportunities.

In the light of financial possibilities, it is worth considering budget options. On this side, quality will be relegated to the background after cost.

When aesthetics are not in the first place, then you can use rolled polymer materials(e.g. roofing membranes), they are excellent for flat roofs. Pitched roofs can also be covered with similar material, but provided that the plank is fixed on top. The basis for such a coating will be fiberglass to isolate sounds, moisture and heat.

Another budget option is to cover the roof slope with ondulin. Although it is subject to curvature under the influence of the weather, it is still quite common.

After previous options it is worth mentioning corrugated board and metal tiles. The color options are huge. The accessories include everything you need to install a roof. The downside of the material will be low sound insulation, for example, during rain. But this is corrected if the substrate is made of polyethylene foam.

It is also important to perform excellent thermal insulation of the roof, to protect the entire building from the effects of temperature changes. In most cases, glass wool is used for insulation. Cheaper than all materials today is foam. However, it is very fragile and has low sound insulation. In this case, glass wool has several advantages, because. it does not undergo combustion, temperature influence, does not shrink and does not stretch.

Roof waterproofing is easily done with vapor barrier film and non-woven polypropylene.

It is worth noting that it is better not to use too cheap materials for roofs, because. most often they are not the most environmentally friendly, and this will affect the health of residents. But here it’s up to you to look: either choose which roof is cheaper or more environmentally friendly.

The roof must be reliable and solid. Otherwise, the entire structure will have a minimum service life.

well, not a dispute, of course ... I just don’t understand the principle of traditionalism without an explanation of its usefulness and profitability and profitability ...

and if my friendline indicates that earlier in antiquity there were few technologies for making non-leaking roofs and therefore one of the advantages of the pitched “Accelerated flow of water due to the greater slope” that you indicated was important, now how does it affect ???

Let's reiterate what you said:
1. Accelerated water runoff due to a greater slope (ok... but pliz highlight the advantage of this, for example, for a straw roof this is certainly relevant ... but in general ???) do we have tropical monsoons planned in the country?

2. Simple organization of the drain (wow, simple! ... or simple in the sense: the main thing is to drain?)

3. Lack of snow bags (I protest! ... there is no rationale for the occurrence of these)

4. Convenient maintenance of the roof through the attic space or attic
(note ... to look at the gap or observe leaks ... and then a very important addition ... if the roof is made of anything, and by the way, in the case you agreed attic rooms doesn't that make sense?)

5. When designing an attic floor, there is no need to build external walls (it is important to understand that an attic is already a consequence of making a decision about a pitched roof ... at first there were pitched roofs and only then they came up with attics ... not vice versa. let's not interfere in a bunch ....) (at the same time I agree that whoever private architecture instant loan now conceived additional meters "a la the second floor" - this solution may turn out to be ... although not. must be counted.)

I agree with the disadvantages.

For flat:
by cons
3. The risk of clogging or freezing of the internal drain - (if at least somehow you can agree with the first part with a stretch ... then the second is not clear in principle ... in what case can it freeze in the internal?)

4. The need for mechanical cleaning of the roof from snow (I protest!) If pitched roofs with their icicles and other hemorrhoids constantly bring problems and troubles, then in the case of flat ones, I don’t know such cases.

I'm adding to the list. (or just repeat for now)

1. - pitched device is a whole art (rafters, rafters, ridge, beams, battens and many others ...

1.1. - I fell asleep in a flat insulation, put the roof on top and that's it,
- in the pitched way, re-laying, etc.)

2. cleaning ...
- on flat ones, even on a snowplow, ride, and be icicle-free ...
- in pitched insurance, try not to fall, etc. risk))

3.rain water…
- in the flat only a border and a hole, .. hmm. well, in a container or .. as well as a bunch of design and innovation ideas.

- in pitched ... hangers for drains, downpipes, drainage gutters (s) with gratings next to the house and a whole complex ...

4.wind
- for flat fie ...
- for pitched art not sailing, etc.
(it recently stormed in Irkutsk, in the news feeds you can see how many stingrays were on the ground and what damage they caused)

5. for an alternative rudimentary and irrelevant so far, flat energy is better suited ...
also more convenient for flat mounting and engineering equipment, such as antennas, deflectors, air conditioners, etc.

6. according to discovery, a contender for entering the top three projects is the transformation of roofs into beds or flower beds, finally ...

and much, much more... what's the word. I can't come to an opinion

For many people, the name "flat roof" is associated primarily with high-rise buildings. A flat roof - the pros and cons of which we will consider in this article - has practically not been used in low-rise construction since a dozen years ago. However, today the creation of such a roof in a country house is not a problem: modern materials and technologies make it possible to create a flat roof with proper consumer characteristics and at an affordable price.

A flat roof is much smaller in area than a pitched roof, which saves on materials and construction and installation work.
Thanks to the relatively smaller area of a flat roof, it is possible to optimize costs.
The construction of a flat roof is easier and faster than pitched roof, since the necessary materials for installation are located right at the feet of workers on a flat surface. The same can be said about the repair and maintenance of a flat roof - working on an almost horizontal roof is incomparably more comfortable than on an inclined one.
On a flat roof, installation and subsequent service work with all kinds of equipment (air conditioning systems, solar panels, antennas, etc.).
The use of a flat roof is an opportunity to get additional useful territory that can be used as a place where you can relax on fresh air, go in for sports, create a garden, flower garden, etc. To date, there are technologies that allow you to cover the roof even with paving slabs or paving stones. Roof paved beautiful tiles, in combination with green lawn, garden furniture, a gazebo and a fireplace, can become a place for a comfortable family vacation.

at home with flat roof very popular now

A flat roof, in addition to the advantages, has a number of disadvantages:

As a result of heavy snowfalls, a lot of snow accumulates on flat roofs, which, when melted, often causes leaks.
Sometimes internal drains are required.
There is a risk of clogging or freezing of the internal drain.
There is a need for mechanical cleaning of the roof from too large accumulations of snow.
It is necessary to regularly monitor the moisture state of the insulation and the tightness of the roof.

Varieties of flat roofs

There are four types of flat roofs:

In accordance with building codes flat roof, the pros and cons of which we examined above, should have a base in the form reinforced concrete slabs ceilings or sheets of corrugated board.

Subtleties of waterproofing

The durability of the roof structure and its resistance to various negative influences depends on the use of special mixtures and technological processes for the production of roofing materials. Depending on the materials of the roof, it is customary to subdivide into three categories:

Bituminous roofs, as well as polymer-bitumen based on ruberoid. These materials are available due to their low cost. Welded bitumen-polymer compositions are rolled waterproofing and roofing sheets based on synthetics, on both sides of which special bitumen is used, which remains elastic even at extremely low temperatures (up to -50 degrees Celsius). During the installation of waterproofing, carried out using gas burners, the rolls are fused together. Roof waterproofing can also be carried out with self-adhesive materials based on polymers and bitumen. In this case, the mastic is applied on the bottom surface of the roll and in the process of processing with a solvent acquires the properties of an adhesive. The disadvantage of bituminous roofing is fragility.
Membrane roofs with a base of foil, rubber or polymers. This material has solid strength, is resistant to fires and other negative environmental influences. The membranes are glued to the screed or simply lie on the base, being loaded with ballast, or they are attached mechanically or with glue. To connect the membrane sheets, special welders, fastening the material with hot air.
Roofs based on liquid polymers, which, after cooling, do not form seams. Such materials are especially often used for structures with complex geometries.

It is very important to make the correct waterproofing of a flat roof.

Whatever material is chosen, the joints between the rolls and the junctions with various roof elements must be waterproof. One of the main components of a successful waterproofing device is a quality sealant. During the period of operation, the roof is subject to negative environmental influences (moisture, hail, stones, strong temperature fluctuations, etc.). Therefore, a high-quality sealant must be resistant to mechanical and thermal influences.

As a sealant, mastic is usually used - putty, which is based on elastic polyurethane resins. After being applied to the roof, the mastic polymerizes, as a result of which a continuous rubber-like membrane is formed, which has waterproofing properties and protects the roofing from mechanical damage.

Mastic is ideal for flat roofing, is safe, has high adhesion to building surfaces, has high resistance to ultraviolet radiation, precipitation and all kinds of microorganisms. It is applied by brush, roller or airless spray in two multi-colored layers, which allows you to control the quality, thickness of the layer and uniform distribution of the sealant.

How to arrange a water drain

Regardless of the materials used, a flat roof must have a certain slope to drain water (usually within 3-5%) that appears on the roof as a result of precipitation. The drainage system should be thought out at the design stage of the building. Gutters determine how efficiently moisture will be removed from the roof surface. To prevent freezing of gutters in winter, they are equipped with special thermal cables.

Drains are organized when both external and internal water supply is created, and unorganized. When creating an internal water supply, the roof surface is divided into approximately equal parts of 150-200 square meters each. In places with a slope, drain funnels equipped with baskets for catching garbage are arranged. Typically, the funnels are located in the center of the roof, and the pipes are inside the building.

Flat roof insulation and vapor barrier rules

Flat roofs need insulation. In the absence of a layer of thermal insulation on the roof surface, condensation forms as a result of the contact of warm air masses and the cold surface of the roof. Condensation appears on the ceilings of the house as water spots, and the roof structure is gradually destroyed.

The roof structure involves a base on which a layer of vapor barrier material is laid. The function of the vapor barrier is to protect the insulation from diffuse moisture coming from the premises of the building. The vapor barrier layer includes a glass fiber reinforced membrane (based on bitumen and polymers) or a vapor barrier film. The layer is laid on top of the screed, and along the edges of the roof structure it is wound vertically to a height exceeding the height of the insulating material. The seams are soldered.

Above the vapor barrier layer, a heater is placed, and on top of it - a waterproofing carpet based on bitumen. If expanded clay acts as a heater, then it is necessary to make a cement screed over it, then laying a couple of layers of waterproofing. If the roof is planned to be light (in the case when significant loads are not expected on it), then the waterproofing is simply glued around the entire perimeter of the roof.

For roofs without attics, both external and internal insulation methods are used. outdoor method used more often, so its execution is easier. There are two options for thermal insulation: two-layer and single-layer. The decision on which option to apply in practice depends on the calculations for heat engineering and the requirements for the strength of the roof. Thermal insulation boards are placed on the roof structure based on the principle of "spread seams". With a two-layer coating with thermal insulation "in a run", the joints of the lower and upper plates also go. In the area where the plates adjoin the parapet, lanterns and walls, heat-insulating bumpers are created. Heat-insulating materials are attached to the base mechanically (screws, dowels), ballast (pebbles, paving slabs) or glue.

Features of roof ventilation

The roof structure must be ventilation system. As a result of a violation of the tightness of the vapor barrier layer, moisture enters the insulation layer. A thick layer of waterproofing prevents evaporation, and moisture accumulates in the insulation. As a result, the material loses its insulating characteristics, and moisture appears in the form of spots on the ceilings of the building. In addition, water causes swelling of the waterproofing, and at low temperatures, freezing water tears off waterproofing material from the base. Temperature fluctuations, mechanical damage contribute to the formation of cracks in the roof, the result of which is its flow.

To avoid these problems, the roof must "breathe". For this, aerators are used - special devices in the form of plastic or metal pipes. They are covered with umbrella caps and are evenly distributed over the entire territory of the roof, gravitating to its highest points. The aeration mechanism works on the basis of the principle of different pressure, which is created by air flows, removing excess moisture vapor from under the roof and preventing water bubbles from forming.

Roofing is a responsible technological operation. Any, even a minor mistake in the design or construction of the roof can cause it to leak in the future. Therefore, when creating a roof, you need to pay Special attention correct selection hydro and thermal insulation materials, accurately calculate the upcoming loads on the roof structure, as well as select a team of competent builders.

durable reliable roof protects a private house from rain, snow, wind and the scorching sun, keeps heat and comfort indoors. And beautiful - gives the architectural appearance of the entire building completeness, originality and expressiveness.

What kind of roof to choose for the house

The roof is built for more than one decade, so during the entire service life it must meet the requirements of safety, durability and functionality. Construction standards have been developed - SNiP, which regulate the main characteristics of structures, the rules for calculating and installing roofs.

The construction and design of the roof are connected with the general architectural solution of a private house and are developed at the design stage. The climate zone, the type of coating, the materials used for the supporting system and the roofing determine which roof to choose for the house. Quality performance works on its installation will allow to operate the structure for a long time, to avoid costly repairs.

Construction projects of private houses developed by architectural bureaus contain turnkey solutions roofs for standard construction. The customer can order individual option which will take into account all the necessary requirements and wishes.

The scheme and material for the manufacture of the enclosing structure depends on its spatial solution. What kind of roof to choose for a private house? The most commonly used are pitched forms, less often flat ones.

Classification of pitched roofs

A slope is a roof plane set with a slope. By the number and location of inclined parts, there are varieties:

Shed

The roof plane has a one-sided slope with an angle of up to 30°, along which drainage is carried out. This type is used to cover small buildings or outbuildings. The advantage of coatings is high resistance to wind loads, the disadvantage is that snow accumulates on the surface, water does not drain well.

gable

In such structures, the rectangular roof planes are directed in opposite directions at an inclination angle of 20-42 °. Snow and water do not linger on the surfaces. With a larger slope, the windage of the roof increases, which can lead to its separation during strong gusts of wind.

Hip

They are called four-sided. One pediment - the triangular part of the facade - is completely or partially replaced with a slope - a hip. The shape is more resistant to wind load than gable. Its varieties are half-hip Dutch with a shortened hip and tent, where the slopes in the form of triangles are located at one angle, connecting at the top point.

Multi-forceps

The complex design combines three or more gable forms that overlap houses with outbuildings, highlight the attic area with windows. Nippers - pediments - are arranged parallel and perpendicular to each other. A spectacular roof is laborious to build, requires more material consumption, and careful execution of joints.

On our website you can find contacts of construction companies that offer roof repair and design services. You can directly communicate with representatives by visiting the exhibition of houses "Low-Rise Country".

Mansard

The space under the roof is used for housing or for business purposes.

Conical, domed or bell-shaped

Roofs of this configuration cover buildings that are round in plan. Due to the high cost of construction, they are found mainly in elite mansions, places of worship and stylized buildings.

Pyramidal or spire-shaped

Used for regular polygonal buildings, have an elongated shape. They decorate the building more than protect from precipitation.

flat roofs

Over the past decade, flat roofing has ceased to be a sign of multi-story or industrial construction. Projects of private houses play on the advantages of roofs without a slope. Terraces, recreation areas, solar panels, antennas, and climatic equipment are placed on them.

In fact, the design is not entirely flat, it has a small slope angle - up to 5 °. This allows rain and melt water to drain through an organized internal or external drain. The slope is formed due to the different thickness of the screed.

Flat roofs have advantages over spatial coverings:

original and fresh design;
the roof can be operated;
the attic space is used as a full-fledged floor;
increased resistance to wind loads.

The main problem that was previously encountered during operation was the insufficient service life of waterproofing. When the protective layer was destroyed, water flowed freely into the room.

Modern materials and technologies make it possible to build durable flat roofs with guaranteed operation for 50 years. Whatever the promises of the manufacturers, special care must be taken during installation when sealing joints and equipping drains.

Disadvantages of a flat roof:

snow accumulation;
the need for regular maintenance;
increased risk of leaks;
icing of catchment funnels in winter.

A flat roof is suitable for individual construction in areas with a mild climate, low rainfall. If there is a lot of snow, heavy rains are frequent, then the best option will be the choice of design with slopes.

Pitched roof device

Rafter system - load-bearing frame roofs. It consists of the elements:

Mauerlat - beams on which the entire structure rests. It is mounted along the perimeter of the walls in the upper part.
rafter legs- inclined elements placed with a step of up to 1 m and interconnected by horizontal runs. They are hanging or layered, depending on the type of support.
The ridge is the top of the roof, the horizontal bar to which the rafters are attached.
Lathing or decking - load-bearing structure for " roofing cake", adding rafter system sustainability.
Roofs - external coating, consisting of layers of insulation, hydro-, vapor barrier, wind protection, roofing material.
Racks, struts, crossbars - vertical, horizontal and diagonal connections, giving the frame rigidity and stability.
Valleys, grooves - docking elements at the intersections of the roof planes.
Overhangs - continuations of slopes outside the outer walls.

Diagram of a gable roof device

The rafter system for private construction, as a rule, is made of wood. The material is accessible and easy to process. It is lightweight and strong enough. You can create any spatial frame without weighing down the system.

Roofing materials are varied. To choose which roof is best for a private house, you need to know the features of their application.

Criterias of choice

When choosing a roofing material for coating, consider the possibility of using it from several sides:

Roof pitch. There are manufacturer-recommended dimensions of the angle of inclination at which the material will effectively perform its functions.
Specifications- durability, weight, strength, safety, fire resistance.
Noisiness - some materials, for example, metal profiled sheets, are able to resonate and amplify impact noise from falling raindrops, hail.
financial availability.
Possibility of do-it-yourself installation, if self-construction is expected.

The enclosing structure should fit into the overall architectural solution in style, in harmony with the surrounding landscape.

Materials for various types of roofing

For pitched roofs with an angle of inclination of 12-45 °, the following materials are used:

Folded metal sheets

They are made of steel, copper, titanium-zinc or aluminium. Fastening to each other is carried out by means of a fold - a special type of seam, performed manually, mechanical devices or self-latching. The roof is light, strong, durable, there is practically no waste after installation, no accessories are needed. Required for manufacturing special tool. The main disadvantage is increased noise. It is eliminated by installing soundproofing. Steel sheets are susceptible to corrosion.

Decking

Rolled products with a polymer coating are painted in different colors, durable, non-flammable, durable. The dimensions of the sheet allow you to quickly cover even large spans. Good combination in terms of quality and price.

metal tile

Successfully imitates expensive natural material. Among the shortcomings are noise common to metal surfaces, high thermal conductivity. Advantages - affordable price, decorative effect, ease of installation, durability.

Other materials

At slope angles of more than 12 ° use bituminous and ceramic tiles, slate, fiber cement sheets.

Slate and piece tiles require a greater slope - from 25 °. This will allow water to drain without lingering on the surface, protect the roof from leaks at joints and overlaps.

Flat roofs are covered with roll-on welded or mastic bulk materials. The first type includes roofing material, roofing felt, glassine. Their main disadvantage is their low resistance to frost, UV radiation, and mechanical stress. Reapplication is required every 5-15 years.

Modern analogues - fiberglass, isoplasts, special polymer membranes - far exceed the previous generation of rolled materials in these indicators, protecting the roof for up to 50 years without repair.

Wooden house - features of the choice of roofing

Tree - perfect material for housing construction. It is warm, environmentally friendly, aesthetically comfortable. It is easy to breathe in such a house, because. wooden walls have good vapor permeability. But they cannot boast of high fire resistance, such as, for example, brick or reinforced concrete, even after repeated treatment with fire retardants.

What kind of roof to choose for a wooden house in order to preserve the aura of natural material and at the same time protect yourself from the possibility of a fire?

to fire resistant roofing materials relate:

ceramic and cement-sand tiles;
metal coatings;
asbestos cement sheets.

Cover wooden houses materials containing bitumen and its derivatives - bituminous tiles, euroslate, are not worth it, because. their combustibility is average (G3 group). They ignite spontaneously at a temperature of 250-300 °, while releasing toxic substances that are dangerous for breathing.

Non-combustible asbestos-cement slate widely used in private construction, but when heated to high temperatures wavy sheets explode, fragments scatter in different directions.

Conclusion

There is an answer to the question of which roof is better for a house: it must be safe, reliable, not afraid of cold, heat, wind and water. And at the same time - for a long time to please the eye.
