Most often, when designing private houses, pitched roofs are used, but cottages with a flat roof, as in the photo, are much less common. In recent years, after the advent of new technologies and modern materials for covering flat roofs, it is possible to create effective waterproofing, despite their unusual shape.

The presence of such a roof makes the appearance of a private house exclusive and original, since it stands out against the background of buildings with hipped or pitched roofs.

Projects of cottages with a flat roof have their own characteristics, and their construction is associated with some nuances, since the roofs on them can be:

Advantages and disadvantages of a flat roof

A flat roof provides the property owner with a number of advantages, including:

The disadvantages of the structural solution of flat roofs include:

• carrying out installation with strict adherence to the technology of their waterproofing and. The slightest violation of the rules as a result of negligence or negligence results in the roof leaking if precipitation accumulates on it. Extraordinary roofing repairs will cost a considerable amount, and sometimes it is necessary to carry out a complete reconstruction of the cottage roof;
• the presence of a large amount of snow on a flat surface in winter requires (if the roof is planned to be used) regular snow removal, which can only be done manually;
• During the melting of snow, a significant load is placed on the waterproofing layer

Features of flat roofs

When developing a project for a cottage with a flat roof, regardless of the number of floors in it, the following features must be taken into account:

Creating a flat lightweight roof

If they plan to build a cottage with a flat roof with a lightweight roof, they do not plan to use it.

The procedure for constructing such a structure is as follows:

As a result of the work performed, a flat roof is obtained, which is of the lightweight type. It performs the functions assigned to it completely, but it is not able to withstand even a slight load. If you want to create a small place for rest on a flat roof, you need to build the roof using a completely different technology.

Construction of an exploitable flat roof

When designing cottages with a flat roof and a hard surface, it is assumed that the created roof will not sag under the weight of the load (read: ""). There are several ways to construct a serviceable pavement.

One of the simplest options is to lay concrete slabs as a floor. For this purpose, the supporting structures must have a significant margin of safety; in addition, installation is carried out using special construction equipment. A roof made of concrete slabs must be insulated, but such work can only be done from inside the room.

Another method is the construction of a roofing floor based on metal support beams - T-bars or I-beams and channels. A boardwalk made of lumber with a minimum thickness of 22 millimeters is laid on top, and a layer of expanded clay of at least 150 millimeters is poured on top of it. The hard covering is provided by a concrete screed.

The most modern way of arranging a solid surface is the use of large-sized ceramic building blocks. They are laid on support beams, and they provide the roof, along with mechanical strength, with fairly good sound insulation and heat insulation characteristics. Among the advantages of such ceramic roofing blocks, one cannot fail to mention their excellent resistance to moisture. Before making a screed for such a roof, backfilling with expanded clay is not required. The disadvantages of ceramic blocks include their high cost.

Cottages are built with a flat roof of a solid type with the installation of roofing membranes (optional). They provide additional waterproofing and improve the performance of a flat roof.

How quickly time flies! It's been 4 years since I built an unusual country house with my own hands. The house uses many non-standard technical solutions, which were previously practically not used in individual construction in Russia. Firstly, the house is heated using, and secondly, the house has a flat roof.

From the very beginning of construction in 2012, I was constantly told that a flat roof is not for our climate (what kind?), that it will definitely leak (why?), and in general, with such a roof, the house looks like a transformer booth (poor Europeans, they have to live in transformer booths).

But most often they tried to prove to me that snow needs to be constantly removed from a flat roof (I wonder why?). Of course, if anyone wants, you can clean it up, no one is stopping you. But on houses with a flat roof there is no need to remove snow. For example, now I have a snow cover more than 80 centimeters thick on my roof! And somewhere there she hid under the snow.

2. Snow on the roof is an additional and completely free insulation.

By the way, as it turns out, many people do not know that a flat roof is not a plane in the direct sense, but a surface with a slope of approximately 2-4 degrees (in fact, a roof is considered flat if its slope angle is from 2 to 20 degrees). And any flat roof must have a drain. It is more correct to make an internal drain for a flat roof, but you can get by with a classic external one. At the time of construction, I did not have sufficient knowledge to design and implement an internal drain, so I made an external one. The advantage of internal drainage is the absence of pipes on the facade.

3. Summer 2013, just made. A flat roof is significantly cheaper than any pitched roof (at least because its area is on average 1.5 times smaller than that of a pitched roof). With it there is no loss of space and such useless space in the house as the attic. It is simpler and easier to insulate - everything is in the same plane.

Let me remind you of the design of my roof pie (from bottom to top):
1. Prefabricated monolithic floor filled with aerated concrete blocks - 250 mm;
2. Insulation using extruded polystyrene foam - 150 mm;
3. Insulation and creation of a slope using wedge-shaped slabs of extruded polystyrene foam - 0-150 mm;
4. Cement screed - 50 mm;
5. Two-layer built-up waterproofing (top layer with sprinkling).

4. Another huge plus of a flat roof is that it is not afraid of hurricanes. Look at the chronicles of hurricanes and how easily the covering is torn off and the rafter system on classic pitched roofs is broken.

5. In the summer of 2016, I finished all the other work on landscaping the surrounding area and decided to do it.

6. By the way, if anyone doesn’t know, then any concrete floor by default has a load-bearing capacity of at least 400 kg per square meter (usually 600-800 kg/m2). While the snow load for the Moscow region is only 180 kg per square meter. This is the maximum calculated snow load, which in reality is rarely achieved, but it is obvious that any ceiling has a huge margin of load-bearing capacity.

7. Another important advantage of a flat roof is that it has completely sealed seams. While the seams on a pitched roof are not airtight, and if the pitched roof is filled with snow and it begins to melt from below (due to insufficient insulation), the pitched roof will leak (especially at the junction of two slopes - the valleys). Look at the neighboring houses with pitched roofs - amazingly, there is snow on them too!

Why doesn’t a flat roof made using technology leak? Everything is very simple. Because it is insulated!

It is the insulation that determines the durability of the roof. It is known that the roof accounts for an average of 40% of the heat loss of the entire building. If the roof is not insulated, or is not insulated well enough, then the heat will rise, and the snow lying on the upper roofing carpet will melt. When frost occurs, the melted snow will freeze again, and when it freezes, as is known, water expands in volume. These multiple thaw-freeze cycles will eventually break down the waterproofing (after 2-3 years) and the flat roof will begin to leak.

8. In the last century, when building houses, they did not think about energy efficiency and saving energy resources, so they usually did not insulate the roof. This led to the fact that the roof waterproofing was constantly being destroyed and the roof was leaking.

If the roof is well insulated, then it has only one “enemy” left - the sun and its ultraviolet radiation. But to protect against this, waterproofing is used with a package, or with special additives (in the case of using). And the most effective way to protect waterproofing from damaging ultraviolet radiation is to make a lawn on the roof, fill it with pebbles or lay tiles. By the way, a more promising waterproofing solution today is a polymer membrane.

A flat roof is even easier to use than a pitched roof. From a flat roof, snow will never fall on your head or tear off your gutters. There is no need to clear the snow, and if you have a lawn, there is no need to keep the gutters clean (all water is filtered through geotextiles and they will not become clogged with fallen leaves).

Therefore, a flat roof is the most reasonable roofing option, especially for a house made of. The main thing is not to violate technology and not to skimp on insulation.

And cleaning snow from a flat roof is not only useless, but also harmful - you can accidentally tear the waterproofing with the sharp edge of a shovel and the roof will begin to leak.

All reports on the construction of a country house with your own hands can be found in chronological order.

Projects of houses with a flat roof

In our country, a flat roof is a rather atypical solution. Therefore, such a house will stand out among other buildings. A flat roof serves in its own way as an indicator of the status of the owner, the breadth of his views and the absence of conventions.

But a house with a flat roof is not just a tribute to fashion and a desire to stand out. If previously only elite apartment buildings were supplied with a serviceable roof, today it is increasingly becoming an attribute of country houses. A flat roof allows you to realize fantasies that owners of pitched roofs never dreamed of. This is a luxurious flower garden and a pond with a beach area. Material benefits also play an important role when choosing such a roof. After all, it eliminates the need to design and build a rafter system. True, a flat roof also has significant disadvantages. For example, the lack of under-roof space, and therefore the lack of thermal insulation that it provides.

A house with a flat roof needs an attic with high-quality hydro- and thermal insulation. To do this you will need expensive materials. No matter how flat the roof is, a minimum slope is still necessary. Usually it is 5-15 degrees. This angle of inclination is enough to prevent the roof from collecting rain and melt water. Moreover, on a perfectly flat roof you will have to make a slope, that is, give it some slope. For this purpose, special materials are used - plates with a certain angle. It is possible to use bulk materials. If you are worried about clearing snow in winter, calm down, you don’t have to pick up a shovel. A warm cable will help solve the problem, thanks to which the snow will constantly melt and flow off the roof on its own. However, even what is essentially a disadvantage can also be an advantage. It is not necessary to remove all the snow from the roof. By leaving it there in an amount safe for the roof, you get natural thermal insulation, which means you can save on heating.

If you decide to order a house project with a flat roof, you should remember that such construction may be associated with certain difficulties. For example, during the installation of a roof, all requirements for waterproofing must be met. Otherwise, you will end up with leaks and water pooling on your roof in the future. You can order an individual project or buy a standard house project with a flat roof. In any case, you will be asked to choose one of two types of roofing. This can be a lightweight or exploitable flat roof. Lightweight roofing does not provide for operation. In this case, the beams are laid on top of the load-bearing walls and fixed in place. The next step is to install the sheathing, then lay the waterproofing in several layers.

The next stage is laying thermal insulation and installing ventilation vents so that condensation does not accumulate in the insulation. Finally, you need to waterproof the roof using roofing membranes. If you choose ready-made house project with a flat roof and would like to arrange a recreation area at the top, then you need to choose a structure with a solid roof designed for significant loads. There are several ways to arrange such a roof. Concrete slabs can serve as floors. It will not be possible to lay such a roof without the use of heavy equipment; in addition, it needs to be insulated. You can also use metal support beams as the basis for the roofing. The most modern method is ceramic roofing blocks. This material will give the roof strength, keep heat inside and keep out sounds from outside. Such blocks are resistant to moisture.

Non-professionals associate a flat roof with the negative legacy of the Soviet past, when administrative buildings of this type had an unsightly, gloomy appearance, and the upper floors of high-rise buildings suffered from constant leaks. Over the past 10-15 years, the production of roofing materials has undergone significant changes, thanks to which it has been possible to create durable, strong and reliable polymer coatings of a new generation. From that moment on, flat roof house designs began to gain popularity.

Single-story buildings are the traditional architectural form of southern coastal cities, resorts and luxury villas in the Art Nouveau style, where a mild climate without much rainfall prevails. The main part of the Russian territory is located in an area of ​​high snow load, so this construction technology began to be introduced recently, when modern roofing materials with improved performance characteristics appeared. Over the past ten years, one-story buildings with a flat roof have been tested in the harsh Russian winters and have demonstrated the following advantages over their pitched counterparts:

1. Space saving. Due to the rational use of space, one-story houses with a flat roof, built using frame technology, are a compact structure that can be placed on a small construction site within the city or in the suburbs. This quality is relevant in the context of a constant increase in the cost of land for development.
2. Saving materials. A flat roof does not have a slope, so less roofing material is spent on this type of roofing than on pitched analogues. During the construction process, less wood is consumed for the rafter frame, which reduces costs. In addition, small flat roofs can be installed yourself without spending money on hiring professional roofers.
3. Possibility of expanding the area. A one-story house with a flat roof can become a transitional option until the need and financial opportunity arise to add a second floor. This versatility will be an additional advantage for young families, the composition of which may soon change.
4. Wide range of roofing options. If a one-story house is equipped with a flat usable roof, it can be equipped with additional space to satisfy a variety of needs: equip sports grounds, recreation areas with barbecues, swimming pools, lay out lawns, beds or flower beds. For homeowners who care about preserving natural resources, home designs with a flat roof are suitable, on which solar panels are installed to provide “clean” energy.

Note! Roofing materials based on cardboard and bitumen impregnations used in the past had a service life of only 5-8 years, were damaged by exposure to sunlight, and cracked due to sudden temperature changes. But coatings made from fiberglass and synthetic rubber with polymer resins will protect the house for 50 years. New generation flooring materials do not require a gas burner, so they are suitable for DIY installation.

A flat roof is a roof that does not have a slope; it rests on all 4 load-bearing walls of the house. This design is a multi-layer coating of rolled or self-leveling waterproofing materials laid on a prepared base. Do-it-yourself installation of a flat roof is carried out by layering, pouring or gluing in the following sequence:

• Base. The first layer of a flat roof is a base made of concrete slabs, wooden beams or corrugated sheets, which are prepared in a special way. A primer is applied to it to reduce surface roughness and increase material adsorption.
• Screed. A screed made of cement-sand mortar serves as a leveling layer, with the help of which the roof is sloped, creating a slope in the places where water inlet funnels will be installed.
• Vapor barrier. This layer of diffuse membrane roofing is a barrier to water vapor that penetrates from the heated room into the thickness of the roof, causing the insulation to become damp. To give the membrane strength, it is reinforced with fiberglass.
• Thermal insulation. To protect a one-story house from cooling and heat loss through a flat roof, thermal insulation material is installed on it. For this purpose, fill-in insulation (expanded clay), glass wool, basalt fiber, slag wool or extruded polystyrene foam are used.
• Waterproofing. Waterproofing of modern flat roofs is carried out using polymer rolls or self-leveling materials. Rolled coverings are laid in several layers to prevent leaks in the connecting seams. Bulk materials (liquid roofing felt, liquid rubber) make it possible to waterproof roofs of complex configurations; their installation does not require preheating.

Important! The quality of installation of a flat roof on a one-story house depends on weather conditions. Experienced roofers and manufacturers recommend laying the roofing in dry, warm weather, when the temperature exceeds 5 degrees. At low temperatures, the lower layer of bitumen materials takes longer to heat up, so installation takes longer and gas consumption increases.

Types of flat roofs

Single-pitched houses with a flat roof fit organically into the urban landscape and look just as good as a country residence. Abundant glazing and the use of natural materials in decoration make the structure light, filled with light and spacious, despite its small size. Depending on the nature of use and financial developers, the following types of flat roofs are used in projects:

Important! The flat roof around the perimeter is fenced with a parapet, a protective barrier that keeps snow masses and rainwater from spontaneous discharge. On exploited roofs, the parapet acts as a fence that prevents people from falling, so it must have a height of at least 1.2 m.

Video instruction

Not everyone likes modern construction. This is immediately clear when flat-roof house designs are mentioned in conversation. Most developers don't like the appearance, but after living in such a building for a while, their perception changes. It is precisely due to its minimalism that this house is considered stylish, but the vast majority of Russian residents are accustomed to pitched roofs; they simply cannot imagine a roof without a slope. In this article I will try to reveal in as much detail as possible the beauty of a house with a flat roof.

One-story house with a flat roof

Just a few decades ago, developers in the CIS countries could not imagine that such beautiful houses could be created in private construction. In addition, thanks to the flat roof, the finished cottage costs significantly less than a building with a rafter system.

Houses with a flat roof and their projects are presented in these photos:

Not so long ago, when there were no materials for high-quality waterproofing of a flat roof, mastic and roofing felt were used. These products could not provide a good service life, so this type of house was written off as scrap, and after high-quality materials entered the domestic market, most developers did not dare to test them. This is why today there are so few private buildings with flat roofs in Russia.

Modern houses, due to their style, can stand out from others. The fact is that most residents make internal drainage. It's convenient, although a little expensive. Due to the internal location of the drainage system on the walls of the building, you will not see any protruding pipes, and due to its high power you will rarely encounter blockages. Some people refer to the fact that as a result of construction, square houses are obtained and they do not want to live in such a box. It is worth noting that this design has a lot of advantages, which I will now tell you.

Pros and cons of a flat roof house

Despite the negative reviews about such houses, the vast majority of them remain unfounded. Many people do not know that due to the lack of a rafter system, the building becomes cheaper by almost a third of the total cost, and you will agree that this is not a small amount.

IMPORTANT: It is better not to use outdated products as roofing materials. For example, bitumen and its derivatives (roofing felt, mastic) will last on the roof for only 5-7 years. When modern products, in the form of polymer membranes or pouring solutions, can serve you for about 50 years without any repairs.

Now, let's look at the other side of the coin. The disadvantages of a flat roof include the following:

• Limited selection in roofing materials. Despite the fact that the roof plane has a slight slope to drain water, most types of coatings cannot be laid on it. Products with high waterproofing protection are suitable as materials.
• Due to the flat surface, repeated cleaning work will have to be carried out in the winter season. Despite its porosity, snow has a serious mass and, in large quantities, can easily destroy an entire building.

• Large heat losses. Due to the simply huge plane, serious heat losses occur. This can be corrected by laying thick insulation in several layers. During preventive inspections, this material needs to be given the most time so that the underlying rooms always remain warm.
• Without laying the insulating cord, the internal drain may freeze in severe frosts.

If you do not take into account these disadvantages and create additional elements in order to eliminate them, then a flat surface is the best of all possible.

Modern houses with a flat roof are built according to crazy designs; if you turn to a good architect, the result can be buildings such as those shown in these photos:

Types of flat roofing

As you know, in life there is almost always some choice. The same is true for the roofing surface. In the roofing area there are only 2 options for using a surface with a flat base:

• Make it exploitable
• Make it unusable

Before starting construction, at the time of design, it is very important to decide on this issue. After all, if the roof is used, it will require the installation of massive elements that will easily withstand serious weights. In cases where an unused surface is installed, the entire building can be framed. By the way, wooden frame houses are very popular in America and warm European countries. As for Russia, it is better to use thick walls here, otherwise winter will be difficult.

The roof in use is designed to accommodate heavy elements. Often, European residents install recreation areas, workshops, and gazebos on their roofs. This is very convenient if you want to relax in company, but do not want dirt to be carried into the house.

Unused roofs cannot be used as a recreation area. Often, poured roofs are laid on such surfaces, therefore, you can move along them only on bridges or ladders. Such materials allow you to save money, but at the same time they have maximum waterproofing properties, so you can pour a pool on such a roof, but of course you shouldn’t do this.

In addition, flat roofs are divided into several types according to their structure:

• Traditional
• Inversion
• Breathable

A traditional roofing pie has the following structure:

• Base
• Screed
• Vapor barrier layer
• Thermal insulation
• Waterproofing
• Finish coating

As you can see, here the thermal insulation material is under the waterproofing. This is beneficial only if during operation such a cake will not be subject to serious loads, therefore, it is ideal for an unused surface.

In an inversion cake, the order of layers is slightly changed and looks like this:

• Base
• Screed
• Waterproofing (usually roofing felt)
• Thermal insulation boards

• High permeability vapor permeable film
• Screed
• Finish coating

As you can see, there are two layers of screed here. This is done to ensure that the heat-insulating boards do not deform under weight and always perform their functional tasks efficiently.

As for breathable roofs, their structure can be traditional or inverted, but aerators or deflectors are installed on them as an additional element. These devices are very useful when natural ventilation cannot provide high-quality ventilation of the premises, and due to the fact that flat roofs are built with parapets, the air flow is extremely small.

Finding a suitable house with a flat roof is not a problem now; just look at the catalog of projects offered by construction companies. If you want a cozy building, then you need to contact the design bureaus directly, otherwise your house will be typical and, as a rule, not very convenient for you or your loved ones. Today, there are more and more houses with exploitable roofs. This is due to the fact that additional objects can be installed on it, for example, a recreation area. By the way, people on the roof are completely safe, because according to building codes, the minimum height of the fence should be 120 centimeters.

As an example, let's look at one-story houses, or rather their projects in the following photos:

As you can see, minimalism in all cases is an important component of these buildings. You need to get used to this style, but most Russian residents are not ready for this yet; they prefer a house made of timber and the usual two slopes above their heads.

Flat roof base

The elements used on the floors depend on the materials that were used to construct the walls of the building. For example, if the load-bearing walls are frame, then the floors must be extremely light, otherwise the entire structure may collapse. Today in construction only a few elements are used for floor coverings:

• Reinforced concrete slabs (flat or hollow)
• Monolithic concrete layer
• Thick sheets of corrugated sheets

Between floors, a thermal insulation and waterproofing layer is not laid on these elements, but when completing the last floor, this is mandatory.

As you already know, a flat roof roofing pie can be classic or inverted. The latter does not imply that any heavy elements will subsequently be laid on the roof surface. As a rule, such a plane is filled with bulk material or bitumen products are laid on it. You can see what such a one-story house looks like in this photo:

As for the surfaces being used, the variety of roofing solutions here is off the charts. You can plant trees on the roof, cover the area with lawn, put up a gazebo and much more. But the most important thing is, of course, the roofing. Here it is very important to consider the nature of your plane. For example, if you want to put up a gazebo, then it would be a good idea to cover the area adjacent to it with grass or flowers, and make the approach from paving slabs. Projects of houses with a flat roof allow you to do something else, the main thing is to understand what exactly you want.

You can often find pressure coverings on the roofs of private houses. This is gravel and soil. The load from such materials is very high, therefore it is exclusively suitable for the types of roofs in use. It is worth noting that their structure will be slightly different from the inversion one, but you can check this with a designer.

Reinforced concrete slabs with screed are an ideal solution if you are considering cottage projects in a catalog that contains budget options. By laying these elements as a ceiling, you will get a sufficiently rigid base to create a good usable roof.

The cheapest construction option would be a frame building. It is worth noting that this method of constructing buildings is very popular in hot countries, but is not entirely suitable for our climate. Nevertheless, such a building can be used for economic purposes. If the walls are framed, therefore, it is no longer possible to place reinforced concrete elements on top, they will simply crush the structure. This problem can be solved with the help of corrugated sheets. The metal base is very light, and due to its high rigidity it will not deform even under strong weights, the main thing is to distribute them well.

Light materials are often laid on the roofs of frame houses. For example, polystyrene foam boards are used as thermal insulation products, and modern membranes are used instead of heavy coatings. Thanks to this, the result is a very light and inexpensive building that can be used for any purpose.

Materials for roofing pie

The roofing pie in a flat roof plays a rather important role, because due to the violation of one layer, others will suffer and, ultimately, such a chain will reach the thermal insulation, and this is the basis of such a structure that retains the heat of the room.

To create a quality pie you will have to think about how to choose the right materials:

• Vapor barrier
• Thermal insulation boards
• Coating

The design of a modern house should include polymer or bitumen membranes as a vapor barrier material. As for outdated polyethylene, it is better to avoid it, as it will not give the cake reliability and will fail quite quickly.

Selecting thermal insulation products is somewhat more difficult, because there are quite a lot of them. Fortunately, we have criteria that weed out unnecessary materials. Thermal insulation of a flat roof must be rigid and withstand high static and dynamic loads. In addition, they must be hydrophobic, so there are only a few options left:

• Expanded polystyrene
• Hard mineral wool
• Foam glass
• Expanded clay filler

IMPORTANT: Foam glass is a very effective thermal insulation material, but its price is quite high. If you are planning to build a high-quality building that will last for decades, then this is the one you should choose.

Expanded clay is a low-performing product and is rarely used as thermal insulation. Due to its flowability and large fraction, it will be necessary to pour a very large layer, and this will be an additional load on the walls and ceilings.

As you already understood, the coating should also be light and not allow moisture to pass through in any way. This list includes: flooded roofs, membranes and bitumen derivatives such as roofing felt.

Drainage system

The gutter system on a flat roof deserves its own topic, but I will try to explain everything briefly.

According to building codes, it is impossible to create a drainage system with a slope of less than 15 degrees, therefore, in this case they are not suitable for us. The closest suitable alternative here would be the following:

• Create a system using overhead gutters
• Construct an internal drain

It is worth noting that both methods have their positive sides and disadvantages. For example, an external drainage system will spoil the appearance of a building with a flat roof. Of course, this problem can be solved with the help of design tricks, but you will have to spend additional money on this. As for the internal system, here I want to talk more openly.

Internal drainage is the most optimal solution for removing precipitation from a flat roof. In order for the system to function all year round, heating cables are laid in it. They can be purchased at any construction market. In addition, such a system should be created when conducting zero construction.

Internal drainage is divided into two types:

• Gravity
• Siphon

Gravity drainage is the most primitive sediment removal system. It is not difficult to calculate, and installation can be carried out by a person far from the construction business. This device includes such elements as: risers, outlet pipes, water intake funnels. It is worth noting that the gravity system cannot boast of high performance, therefore, during heavy rainfalls it may experience problems, resulting in a huge puddle forming on the roof surface. Developers attribute its low price to positive aspects.

The siphon system is more complex and more efficient. It can easily cope with large amounts of rainfall without experiencing any difficulties. The essence of its work is that it does not remove water from the pipes until a sufficient amount has accumulated in them, and then, due to gravity, discharges them into the storm drain. By the way, after the process of removing water in the pipes has begun, different pressures are formed from above and precipitation from the roof leaves through the pipes at an even greater speed. Due to this, such a system very rarely becomes clogged, and therefore does not require practically any attention. The disadvantages include its high cost and problematic design.

Projects of one-story houses with a flat roof

Now that you understand flat roof buildings, you can start looking at some projects.

Rectangular house with garage

The total living area will be about 168 square meters. The foundation is made of MZFL slabs or piles are installed. The roof is flat, and PVC membrane or bitumen products are used as covering. The number of living rooms in this project is 3. The drainage system is internal. The building has no basement. There is a garage. The walls will be built from gas silicate, expanded clay concrete, brick or wood concrete. The thickness of the supporting structures is 400 millimeters, however, they can be increased. Everything described above can be changed within reason.

Such house designs with many rooms and a garage for two cars are suitable for young families with children. There is a garage, a living room and two spacious rooms.

One-story house in high-tech style

Modern one-story houses should be created with style. These projects are intended for business people whose work comes first. However, this building is suitable for a small family as a summer cottage or country house. The project is compact and has two living rooms, a spacious kitchen combined with a living room and a cozy terrace. As you can see, there is nothing superfluous or distracting.

As for the garage, it is slightly pushed forward. The entrance door to it is located in the building, this is convenient if you carefully monitor your car and try to repair it as any malfunctions arise.

PVC membrane or bitumen roll products are used as a covering on a flat roof. Living area 96 square meters. The number of rooms is two. The foundation is created from slabs 20 centimeters thick or mounted on piles. The building does not have a basement, but it does have a garage for one car.
