House project 2 floors with a flat roof. Flat roof houses - design features, best projects and ideas (75 photos)

Projects of houses with flat roof have become more popular all over the world lately. Some instances of houses can be safely called masterpieces of architecture. In our country, this direction is still developing, therefore, choosing such a solution for construction, you become the owner of an exclusive modern home.

Flat-roofed houses look spectacular, and are also endowed with a number of advantages:

• roof construction will take less time and cost less;
• ease of maintenance, cleaning and repair work is carried out easier and without the use of special equipment;
• the possibility of useful use of the roof area, for example, to arrange a terrace, tables for relaxation, a flower garden or a sports place.

Construction of houses with a flat roof

Despite its apparent simplicity, the strength of the house will be achieved only with careful carrying out of the necessary calculations, especially with regard to ensuring a sufficient level of waterproofing and water drainage, in case of an error, the structure may collapse. That is why for the design and construction of houses with a flat roof, it is necessary to contact specialists who have sufficient experience and comply with the required building codes and standards.

Our catalog contains many finished projects houses with a flat roof. Using a convenient filter, you will find various houses by area, number of floors and material of execution (brick, aerated concrete, frame) with a photo and price for construction.

If no cottage project fits in the catalog, we will gladly develop individual project for you, where we will take into account and implement all your wishes.

Cooperating with Villaexpert, you can be sure that the construction of a turnkey flat roof house will be carried out at the highest level and at a reasonable price, and you will receive a house project as a gift.

Houses with a flat roof could be found in our country infrequently. However, today flat-roof house designs are being considered again, so you should pay attention to their advantages, disadvantages and features. This article will talk about the advantages and disadvantages of such projects, the features of laying a flat roof and the design options for the roof space.

The reason for the increasing popularity of flat roofs today is modern design trends. This was facilitated by the emergence of new construction and roofing materials, which made it possible to create not only pitched or hipped roofs, but also high-quality flat roofs.

Since the flat roof device has some differences from other traditional options, the construction technology will also differ. First of all, this concerns the waterproofing of the surface, as well as the drainage system.

In the process of considering the idea of ​​\u200b\u200bcreating a flat roof in a private house, you should pay attention to the following advantages of this solution:

• if, then such a roof fits perfectly into general form. Looks original like square houses with a flat roof, and rectangular;
• the construction of a flat roof requires less time, since it has a smaller area, so working on such a surface is easier and more convenient;
• a flat roof provides the opportunity to use this extra space. For example, a cozy terrace can be arranged upstairs;
• when it comes to maintenance Nothing is easier than working on a flat roof. There is no need to involve steeplejacks to clean drains or ventilation ducts. Almost any flat roof repair can be done by the owner himself;

• The space of a flat roof can be used by the owners not only as a recreation area, but also for the installation of various specialized equipment. For example, many want to install solar panels as an alternative source of electricity. The same applies to wind turbines, all kinds of heaters and systems designed to collect rainwater.

The nuances of building houses with a flat roof: photo examples

Speaking about the shortcomings and difficulties associated with the implementation of projects of modern houses with a flat roof, it is puzzling that despite the significantly smaller area, as well as the relative low cost of roofing materials, building a flat one is no cheaper.

This is due to the fact that high-quality reinforced concrete floors are required for a flat roof. This issue is especially relevant if the roof surface will be used. The use of this space creates a significant load on the entire structure of the house, including the foundation and walls. Thus, saving on the roof leads to an increase in the overall cost of building a house.

It is also impossible to unambiguously answer the question of how to solve the problem of snow accumulating on the roof surface. There is an opinion that the layer of snow has some positive influence, creating additional thermal insulation, which leads to a decrease in heat loss. But one cannot ignore the fact that snow is an additional load on the building.

Often one has to deal with the fact that, under the condition of a violation of the tightness of the roof, the process of melting snow is accompanied by a leak of the roof. To avoid this, it is necessary to initially ensure that the materials for waterproofing a flat roof are of high quality and are installed in accordance with the requirements and recommendations.

Projects of houses with a flat roof: types of structures and their purpose

Modern flat roof houses can vary depending on the type of roof. Accordingly, this will affect the methods of construction, and the further operation of the surface.

The space of the roof allows the owners to be regularly on its surface, as well as to install various items without risk of damage. The base of such a roof should be as rigid as possible, so reinforced concrete is most often used for this purpose. Special requirements are also imposed on the heat insulator: it must be resistant to severe loads, and also be characterized by high compressive strength.

Non-exploited roofs are not designed for serious loads. In this case, it is possible to replace concrete base to less durable wood. In this case, a house with a flat roof is equipped with special bridges or ladders, which reduce the load on the surface and prevent damage if it is necessary to move along the roof.

Inverted roofs are a special type that provides for the location of insulation above the waterproofing layer. This allows you to protect the lower layer from the effects of external factors: temperature differences, sun rays and mechanical loads. It also increases the number of allowed cycles of thawing and freezing of the material.

In most cases, this type of roof is used as an exploitable one, since it is possible to move freely along it, as well as install moderately heavy pieces of furniture and decor. Moreover, it is this type of roof that is considered the most durable among others.

Important! Regardless of the type of roof you choose, make sure you have the right one. drainage system. There are special external drain funnels for flat roofs that can effectively solve the problem of water accumulation.

Flat roof options for a private house: how you can use the space

Considering the fact that each square meter territory has its own cost, you have to save, using space rationally. And in this matter with a flat roof occupy one of the leading positions. After all, in the case of arranging an exploited roof, the owners actually get another floor, albeit subject to seasonal use. Today, even frame houses with a flat roof.

Such a solution may make it possible to abandon the traditional veranda if the size of the plot is not too large. For many owners of small plots, a rooftop garden is a great solution.

Other common uses for a flat roof include arranging a recreation area, such as a gazebo. With a flat roof, the dream of an installation or a barbecue becomes possible.

Another very interesting option is the arrangement on the territory of the roof of the pool. Of course, this will require considerable financial costs, as well as a large amount of work related to the calculation of the upcoming load. However, if you entrust it to professionals, you can get an excellent place to relax. As an example, consider a few photos one-story houses with a flat roof, equipped in this way.

Helpful advice! In order to create a special atmosphere and comfort on the roof, you should take care of the availability good lighting. These may be small Spotlights or garlands. The main thing is that they are designed for operation in the street.

Another original solution for arranging one-story house with a flat roof playground. For a small house, the option of installing exercise equipment or arranging a basketball court is suitable. For larger houses, designers provide even more original solutions. Yes, you can meet projects two-storey houses with a flat roof, which are equipped with a tennis court and a platform for landing a helicopter.

How to make a flat roof: features of construction technology

Speaking of houses with a flat roof, you need to understand that they still have some, albeit a slight slope. Usually this figure does not exceed 5o. But this small slope is very important, as it allows rainwater to run off towards the drain.

Since a flat roof consists of many layers, in the process of laying them, it is necessary to strictly observe not only the technology, but also the time intervals. The quality of materials also plays an important role. Therefore, saving in this matter is highly discouraged.

Consider what each layer of the "pie" of the roof consists of, and what you should pay attention to during the construction process.

Rigid base. As already mentioned, if the roof is planned to be operated, it is usually made of reinforced concrete. As preparatory work the base is thoroughly cleaned and then leveled. For this purpose, use cement screed, as it perfectly eliminates all small cracks, cracks and chips. At this stage, it is important to wait for the solution to dry completely before moving on to further work.

Vapor barrier layer. As a vapor barrier material for flat roofs, a bitumen-polymer film or a vapor barrier is usually used. The main task of this layer is to provide reliable protection against moisture and condensate, preventing them from getting from inside the building to building materials. At this stage, it is important to seal all joints and seams as carefully as possible, since they represent the main danger.

Warming. This layer directly determines the term and quality of operation of a flat roof, and therefore it is worth dwelling on its features separately. Unlike pitched structures, in this case there is no space under the roof. Usually it serves as additional thermal insulation, so the importance of high-quality insulation increases greatly.

The most popular material used for this purpose is mineral wool. With features such as fire resistance, long life, resistance to moisture and steam, and compression, this option is almost ideal.

Another advantage that mineral wool has is that a layer of waterproofing material can be laid directly on top of it. Usually to improve thermal insulation characteristics flat roof, use a two-layer insulation system. In this case, the bottom layer takes on the main thermal insulation function, while the top layer serves for distribution. You can learn more about this by looking at several photo projects of one-story houses with a flat roof.

Features of the choice of waterproofing material for a flat roof

For waterproofing, a durable, stable and elastic material is used that is not affected by temperatures and microorganisms. In the case of arranging an unused roof, bitumen or roofing material is suitable, in all others it is better to give preference to more modern materials, for example, a PVC membrane.

Interesting! Modern waterproofing materials are able to withstand severe loads, which becomes an advantage when arranging a roof garden.

There are several options for solving this problem:

• penetrating (diffuse) membrane;
• EPDM membrane;
• waterproofing agents that are applied by spraying, for example, liquid rubber;
• PVC membrane.

Subject to high-quality installation and compliance with all recommendations, the operational life of such materials will be up to 30 years. In addition, almost no mechanical impact can damage them.

If we talk about which of the listed options is better, then the leading position is occupied by a PVC membrane. Due to the fact that they are made of polyvinyl chloride, they are lightweight, do not light up and are extremely resistant to ultraviolet radiation.

Helpful advice! If we are talking about arranging a roof that has a complex geometric structure, it will be more efficient to use liquid polymers as waterproofing. This will avoid seams. It's also better to use soft roof. The technology of mounting a flat roof in this case is greatly simplified.

Features of the arrangement of the drainage system in the projects of houses with a flat roof: photo

The most important factor determining the period of operation of a flat roof is the quality of the arrangement of the drainage system. This is necessary to eliminate the risk of water stagnation on the surface and, as a result, damage to materials. One of two systems can be provided in the project of the house - internal or external.

Sometimes, in order to prevent the accumulation of snow and ice in the drainage system, heating is additionally equipped, which consists of a special cable that heats up.

Due to the presence of a slight slope, water enters the funnels and then is discharged from the house. At this stage, it is important to pay attention to the quality of the waterproofing of the places where the elements adjoin the roof. This allows you to keep the design of the facade of the house with a flat roof in its original form and prevents erosion of the foundation.

Helpful advice! In order to prevent clogging of the drainage system, it is recommended to take care of the presence of a special mesh that will serve to “catch” debris.

House with a flat roof: a catalog of projects and features of the implementation of original ideas

Incredibly spectacular look on the roof of the house, plants planted directly on the surface of the roof, and not in pots. But this technology has its own nuances, which you need to familiarize yourself with in advance.

A layer of geotextile is laid between the drainage and the soil. This prevents the process of washing out the soil into the drainage, as well as its washing. This is facilitated by the dense arrangement of synthetic fibers.

If planting is not planned, the procedure is somewhat simplified and can be reduced to applying concrete screed, on top of which tiles will be laid or a special sand and gravel mixture will be poured. Which option is preferable depends on how the roof will be used in the future.

Considering the projects of one-story houses with a flat roof, you can see how big a role the presence of such additional space plays. If the territory is properly equipped, this place can become a favorite for the whole family. In addition, this idea can be implemented for other buildings. For example, you can make a bath with a flat roof or a gazebo.

House with flat roof, among the same type of "boxes" with a pitched roof, looks fresh and unusual. Therefore, every year the number of suburban residents who are seriously considering the construction of such a house for permanent residence is increasing. Fans of the "cubic" design are captivated by the wow effect and increased attention from the neighbors. Someone wants to place engineering equipment on the roof, or lay out a lawn and equip places for recreation. Still others believe that it is cheaper and easier to build a house with a flat roof than with a pitched one. Is it really? Consider the main pros and cons of these buildings and conclude whether they are suitable for our country. To do this, we will answer the following questions:

• Why is it difficult to choose a suitable plot for a "cubic" cottage
• Is it true that flat roofs are not suitable for our climate?
• Why does a flat roof leak?
• A flat roof is simpler and cheaper than a pitched one - this is a myth
• Why flat roofs are difficult to repair

1. House with a flat roof and domestic realities

Most suburban residents look at cottages with a flat roof with skepticism, calling these houses “boxes”. Why? Flat roof houses came to us from abroad. Traditionally, they were erected in countries with a warm climate, where there is practically no winter, heavy snowfalls, severe frosts with sudden thaws, prolonged rains, but strong winds blow. For example, somewhere on the Mediterranean coast. Then these houses turned into a fashionable design trend"not for everyone" in Western Europe, and from there they have already come to us.

I see that we mainly build houses with pitched roofs. But, is it really necessary? In Germany and Switzerland, flat-roof house designs have long been offered. What can be the disadvantages of a flat roof, in addition to an imaginary unaesthetic appearance?

Indeed, can a cottage with panoramic windows in the photo below leave anyone indifferent?

Or such a high-tech house with a flat roof in the forest.

Or a cottage, on the roof of which an observation deck is made, a lawn is laid out and a place to relax is equipped.

Now imagine these houses with us. Harsh winter. In an ordinary - not an elite village, where roads float in spring and autumn, and plots are fenced with a profiled sheet. Houses in the mass are finished with siding or lined with facing bricks. And pitched roofs are covered with slate, metal tiles or, less often, a more expensive solution - shingles. The picture doesn't add up. Something is missing, isn't it? You no longer want to sit on the flat roof of the house, as you dreamed, with a cup of tea or coffee. After all, from there you can see not the ocean, sea, mountains or nature untouched by man, but dense rural buildings or, at best, fields overgrown with grass.

A house with a flat roof, in high-tech style, looks advantageous only on a spacious isolated area, for example, on a slope, with beautiful view on a forest, lake or river. The flat-roofed cottage is lost without landscape design, and among solid, but the same type of houses, it looks like a "white crow".

This is where the first "pitfall" - dreams of a stylish house with a flat roof are broken when you realize,how much will the plot cost on which the cottage will look as it should.

Having conceived the construction of a house with a claim for a non-standard foreign design, select the appropriate site for it.

2. Reliability of a flat roof in our climate

When you look at beautiful houses, which are not one hundred years old, ask yourself why they were built this way and not otherwise. Why do houses built in the coastal zone somewhere in Norway, Sweden or Scotland have no overhangs and the usual drain? They are simply not needed because of the strong winds that turn the rain into a horizontal stream of water hitting the walls. The same is true for houses with flat roofs. They were built in a warm climate, where there is little rainfall, but a strong wind load.

A flat roof is more wind resistant than a pitched one.

Our ancestors are smart people. They considered the design of the house from the point of view of practicality, based on the climatic conditions of residence. Why were flat roofs built in Central Asia? Are they pitched on the Central Russian Upland? In the Baltics, not just pitched, but with an acute angle of the ridge? pitched roof with a slope of 45 degrees, in the Moscow region or in Saratov, will provide reliable protection from rain or snow for 20-25 years, even if covered with cheap corrugated board or slate.

Flat roof, with the right approach to construction and use modern materials, will also provide reliable protection for the house from precipitation and will not leak.

The only question is how much 1 sq. m of such a roof with a guarantee that it will not quickly leak with frequent transitions through 0. Icing. Nighttime freezing and daytime thawing of snow cover. Lingering downpours. And most importantly - how to make such a roof so that it serves for a long time in our climate?

The second difficulty in building a cottage with a trouble-free flat roof is severe Russian conditions operation.

3. The main problem of building a reliable house with a flat roof in the Russian Federation

link82 FORUMHOUSE member

The company built a house with a flat roof for me. On the edges made 6 pcs. heated funnels and brought out to the sides, through the parapet, drain pipes. Is it correct? Maybe it was necessary to make a slope in the center and, with a small roof area, put two funnels instead of six? And let the pipe inside the building. Bring out in the basement and further into storm sewer? I am afraid that the knee, which is brought out of the funnel into the street, will freeze. Ice has already formed on the pipes. What if the pipe burst due to frost? How to fix it? Throw a heating cable? So much money has already been spent on this roof!

Flat roof house built in 2013.

In addition to problems with drainage, another one was added. When link82 I came to check the house, I found that the roof was leaking in several places. Water went from the second floor to the first. The whole drywall floated. Now you have to swear with the builders. Trying to take the money, and completely redo the roof. According to Michael-snabss(the portal user is professionally engaged in the construction of flat roofs) in this example, a whole bunch of errors have been collected. The main of which - builders who just don't know how to make flat roofs the right way.

When building a house with a flat roof, do not chase cheapness. Each step of the builders and stage of work needs strict control. More thorough than when erecting a pitched. Mistakes are costly!

The roof was most likely made of a built-up waterproofing material - stekloizol. The tree played and the fiberglass tore. Repair of this roof with a special roofing membrane will cost from 130 to 200 thousand rubles.

The third factor complicating the construction of a cottage with a flat roof in the Russian Federation - lack of highly qualified builders who know exactly how to build just such houses. How to use and combine materials with each other. What tools are needed for this. Even if the future owner of a flat roof house has a detailed project, and he should be, then everything can be spoiled by “specialists” working on the principle: “we always build like this and no one has complained yet!”.

Flat roofing should only be done by professionals.

4. Is flat roofing cheaper and easier than pitched roofing?

Usually, when it comes to the benefits of a flat roof, you can hear the argument that it is cheaper than a pitched one. Why? Less area - less material consumption. It is easier to make an overlap, because. no need for a classic truss system. No need to equip attic floor etc. And it's true, but as they say, the point is in the details.

If we simply consider the "pie" of a flat roof, then on the basis, for example concrete plates overlappings, fit:

• vapor barrier;
• thermal insulation;
• waterproofing.

Or the so-called. inverted flat roof where the layers go like this:

• waterproofing;
• thermal insulation;
• finishing layer.

In an inverted flat roof, the waterproofing layer is located under the insulation and “works” in more benign conditions, because. from above, from the negative influence of weather phenomena, it is protected by rubble, tiles or soil with a lawn. Those. a ballast flat roof is being installed.

But, when building a flat roof, it is necessary:

• Arrange slopes for water drainage - about 2 cm per 1 running meter. Slopes are usually made with a concrete screed or wedge-shaped insulation elements.
• Lay several layers of insulation. If stone wool is used rather than extruded polystyrene foam, install aerators to remove water vapor from the insulation.
• Put water intake funnels with electric heating, otherwise, due to the formed ice, they will not divert water from the roof.

One water intake funnel, 110 mm in diameter, drains water from an area of ​​up to 300 square meters. m.

• Mount drainpipe with a slope of 3 cm per 1 linear meter.
• Qualitatively make waterproofing from PVC, TPO or expensive EPDM membranes. TPO membranes are less elastic than PVC membranes, but have higher strength. Welding TPO membranes requires professional installers with special equipment. The advantage of EPDM membranes is a large format rather than a smaller one welds, the more reliable a flat roof.

When installing a flat roof, you will have to take into account many nuances.

Calculate the snow load depending on the region of residence. For example, Moscow and St. Petersburg belong to the third climatic region. Snow load on a flat roof, with a slope of 2%, in the Moscow region will be 180 kg per 1 sq. km. m. In the fourth climatic region, the snow load is 240 kg per 1 sq. km. m, and in the fifth already 320 kg. Do not forget that the weight of 1 m 3 of loose freshly fallen snow is on average 50 - 100 kg. Already caked 350 kg. A cube of wet or melting snow weighs approximately 400-600 kg.

With a properly calculated flat roof, snow does not need to be removed in winter. The excess is blown away by the wind, and loose snow becomes a heat insulator.

But, the load on a flat roof must be considered with a larger margin than on a pitched one, subject to force majeure circumstances. For example, the water intake funnels were clogged, the heating cable burned out, and the water did not leave the roof. For a couple of days, the monthly rate of snow fell, but there was no wind to blow it away and it lies on the roof. The additional weight on the roof puts pressure on the walls, which in turn transfer the load to the foundation, which redistributes it onto the subgrade. The further north, the greater the load. We will add a mass of crushed stone or soil with grass if a ballast flat roof is being arranged.

From here - the optimal design of a cottage with a flat roof is not a frame or wooden house, and the stone structure, calculated by the designer and built of aerated concrete, brick, warm ceramics, according to monolithic technology. Because "cubic" design involves large unsupported spaces, then it will no longer be possible to block a span of more than 6 m with a tree. Farms, I-beams are needed wooden beams, hollow reinforced concrete floor slabs, monolithic floor or prefabricated monolithic floor. Do not forget to add expensive facade finishing solutions to the cost of a house with a flat roof.

You can't finish a house like this cheaply.

Planken is used, burnt wood, hand-molded brick, wet facade, combined facades made of wood and stone. And you can’t put standard windows in a house with a flat roof. Large or panoramic are needed. Add to this additional areas of parapets, which also need to be insulated and finished. This increases the cost of construction.

The fourth factor - a house with a flat roof cannot be called budget construction.

Consider the costs not only for the roof, comparing the final estimate with flat and pitched, but for the total cost of the entire “box” with the finish.

5. Low maintainability of a flat roof

sv2321 FORUMHOUSE user

I have a flat roof house. Waterproofing - membrane. I'm struggling with the roof. As they say, water will always find a hole. I like a flat roof, but I think I will abandon it and remake it with a pitched one, although I will have to change the entire architecture of the house. And that's why:

• There is no absolute guarantee that all flat roof joints will be airtight. Enough microcracks and gone. If there is a slope, then small defects are not critical;
• Snow lingers on a flat roof. He melts. Water fills microcracks. Frost struck at night. The water is frozen. With frequent daily freeze-thaw cycles, microcracks increase and then break. They are getting bigger. The pitched roof has no welded sections and there is nothing to tear there. In the most unfortunate case, there will be a small temporary leak without progressive consequences. It is easy to find and repair;
• The most annoying. On a flat roof, you will never know exactly where the defect has formed. A leak in one place, and water dripping from the ceiling in a completely different place. Masters will come, check the joints and find one of the defects, and the rest will remain. If the roof is inverted or loaded with gravel, then troubleshooting is an even bigger problem.

According to the user, the optimal roof for our climate is pitched. The angles at the slopes compensate for the crooked hands of the builders and the change in the properties of materials over time, and the overhangs protect the walls and finishing from precipitation.

So, fifth - low maintainability. The quality of a flat roof is greatly influenced by the human factor.

If it leaks pitched roof with a cold attic, it is not difficult to find and repair a defective area. In extreme cases, you can dismantle the coating and perform local repairs or get close to the problem area from the inside. In the case of a flat roof, leak detection and repair is made more difficult by the complex pie. Many layers in the design, especially in the so-called. "green roof". The presence of a concrete screed, etc.

findings

Houses with a flat roof certainly look beautiful and stylish. Make a flat hassle-free roof that will serve long years in our climate also possible. The only question is the total cost of all decisions and its expediency. Anyone who has been involved in the installation or repair of roofs in our climate knows that in the summer, a roof hot in the sun - last place Where would you like to sit with your family? or friends. Hot and stuffy. I would like to quickly go into the shadows. If there are small children in the house, then the exploited flat roof is superfluous headache for parents. You can also organize a shaded private place to relax with barbecue on a small area. Sunbathing is pleasant in the garden on the grass, throwing a towel or spreading out a deck chair, and not in front of all the neighbors and passers-by on the roof. The suburbs simply want solitude, and not stick out their private lives for everyone to see. Let's add our changeable weather. Rain. The wind, which at a height is felt quite differently than below. In total, how many days a year will really be left to relax on a flat roof? Let's add the need to arrange a place to go to the roof directly from the house. Do not climb onto a flat roof along the stairs, which are fixed on the facade. What's left? Unusual "fashionable" design to attract attention. Therefore, whether to build a house with a flat roof or not, let everyone decide for himself, and FORUMHOUSE offers you proven solutions for this.

• how to build a house in our climate with a roof without overhangs with a hidden gutter, and what are its advantages.

Stone house with a flat roof: a harmonious combination of exterior and interior. In the video - the design features of a monolithic stone house with a flat roof and an unusual facade finish.

Not as popular as pitched ones.

Most often, their rarity is associated with the peculiarities of the climate in middle lane: accumulation of snow on the roof, formation of puddles during rains.

But the ease of construction of such structures and the provision of decorativeness of the building can serve as a good help when deciding on the choice of roof structure.

Moreover, on such a roof it is possible to equip additional areas, which are especially summer time will good place for recreation and pastime.

Like any constructive solution building elements, straight structures can have positive sides and disadvantages. In the presence of roof features, it is important to identify those parties that will affect the design decision of just such a roof.

The advantages of a flat roof are:

• Primarily, such a roof performs quite effectively building protection functions from external influences;
• does not require much effort and cost(material, physical) for its construction;
• long service life. A flat system does not require expensive maintenance if all the main and additional roof elements are properly installed;
• the ability to install additional amenities on the roof, up to a swimming pool and a garden and sauna area;
• good thermal insulation performance.

To negative factors home improvement with a flat roof:

• Accumulation of snow or rain puddles on the surface;
• there is a risk of freezing or clogging of the internal drain;
• mechanical cleaning of the outer layer is required from snow and leaves;
• inability to use sheet or piece types;
• no way to check status roofing cake(particularly insulation) however, drain and duct systems are much easier to check.

Lack of an attic floor, if available flat design roofs can be an advantage or disadvantage depending on preference.

Types of flat roof

Despite the fact that the construction of a flat roof is quite simple and does not require special skills for its design, these roofs have varieties. Classify them depending on the additional purpose and technical features.

The types of flat systems include:

• Operated. The main requirement for this option is the rigidity of the base, in which an important condition is the preservation of the integrity of the waterproofing layer. The base can be made of concrete screed or. The requirements for provide for the strength of the material and its resistance to static and dynamic loads. The most common outer coating for flat construction is paving slabs , which is installed on additional stands or sand cushions;
• unexploited. Considering that this type of roof is designed to perform exclusively the functions of protecting the building from external factors, there are no special requirements for the rigidity of the insulation layer or the strength of the base. The arrangement of such a roof is much simpler than an operated structure.;
• classical. When arranging the classic type, a vapor barrier layer is laid on the base in order to protect the insulation (mineral wool or polystyrene) from moisture. Waterproofing is provided with bituminous materials;
• inversion. The structure of the roofing provides for the location of the waterproofing layer below the insulation, which prevents the accumulation of moisture in the insulation. At the same time, temperature drops that destroy the waterproofing are minimal under the insulation.

In order to make a project of a house with a flat roof, it is necessary to think over the coverage option in advance.

Where to start designing

The purpose of any roof design lies in right choice and calculating the amount necessary materials , as well as a clear expression of what load all elements involved in the structure will bear.

A project is a plan. AT project plan each stage of the work should be displayed.

The project is most conveniently carried out in a special program, which will help not only to display the future structure, but also to help calculate the dimensions of materials, their load.

Design is done step by step:

• Roof sketch in progress. At this stage, the color, geometric shape of the future roof is approved, with indicators of the dimensions of the roof, the load of materials is calculated taking into account regional atmospheric influences. It should be remembered that snow loads on a flat roof are more significant than on pitched structures;
• calculation of the section of beams and lengths of boards is done truss system . It is very important to correctly determine the pitch of the crate, since it is precisely roof structure withstands the entire load;
• a schematic drawing of the roof. At this stage, the location of all additional elements of the roof structure is taken into account.

After completing the drawing of the roof, they begin to draw up an estimate- the cost of materials, structural elements and tools (if necessary) that are required to complete the work on the arrangement of a flat roof.

Shouldn't get carried away decorative features of these elements, it is most important to pay attention to their functional features.

Lightweight flat roof

A flat lightweight system is installed in regions with a minimum amount of precipitation.

The construction of a lightweight roof is very similar to the creation of a classic flat roof structure.

However, there is some features of its construction:
