    Country or country houses with a flat roof are attractive architectural solutions that are suitable for customers with different needs and budgets. Despite the fact that pitched roofs for cottages are traditionally very popular in Russia, today more and more often the choice is made in favor of originality. A flat roof not only looks exclusive and modern, but also performs its main functions perfectly. With proper operation, it reliably protects against precipitation, provides good heat and sound insulation. The Proekt-Shop online store offers a large selection of flat roof house designs. On the site you can find thoughtful solutions with different layouts. All projects were developed by our experienced specialists.

    Design and operational features of the roof

    A roof can be called flat even if it has a slight slope. Such a height difference is necessary to divert rain or melt water. If it is absent, drainage of another design is provided (for example, a drain system). When choosing a cottage project with a flat roof, it must be borne in mind that such houses have a number of operational features. For example, in winter snow can accumulate on them: it must be removed promptly to avoid leaks. In addition, in such houses it is important to ensure that the roof is airtight and the insulation does not get wet.

    Benefits of a flat roof

    Aesthetics. The houses built according to the projects presented in this section are distinguished by their original and stylish appearance. The abundance of flat surfaces, strict forms and conciseness - all this makes them unlike neighboring buildings. Such projects will be an excellent choice for those who appreciate the uniqueness in the design of the space around them.

    economy. The total area of ​​a flat roof will be significantly less than that of a pitched structure for a similar house. Therefore, when choosing such a project, you can save on materials, and in some cases, on simpler installation.

    Additional area. Flat roof house designs are suitable for those who want to equip a comfortable space for outdoor recreation. Here you can sunbathe, play sports or even receive guests. An additional platform is also suitable for placing solar panels, ventilation elements or other engineering systems.

    A variety of cottage projects with a flat roof

    In the online store Proekt-Shop you can find a solution for every taste. Our catalog of flat roof house projects presents options for building from different materials. Most often, aerated concrete and foam blocks are used for such buildings, and frame buildings are also popular. The projects differ from each other in terms of total and living area, the number of rooms, the presence of a garage and a terrace. When choosing the right option, the number of family members, the need for arranging additional premises are taken into account: offices, games, gyms, etc. The Proekt-Shop online store offers a large selection of projects of one-story houses with a flat roof. As a rule, these are variants of buildings that are compact in area, which are suitable even for small plots. Attics can be used to accommodate additional rooms. The range also includes projects of two-story houses with a flat roof.

    Stylistic features of cottages

    According to 3D models and photos of projects of houses with a flat roof, you can evaluate the appearance of such buildings. Most of them are characterized by the use of straight lines and non-classical forms. Projects of houses with a flat roof in a modern style can be done in different directions:

    • high tech,
    • constructivism,
    • minimalism,
    • cubism, etc.

    Such external design of buildings is often combined with the use of innovative technologies in the arrangement of engineering systems, such as solar panels. In addition, the design of the interior of the house is also often done in high-tech style.

    The type and shape of the roof has always depended on the region and the natural and climatic conditions that existed in it. In northern lands with a lot of rain in summer and snow in winter, various types of pitched roofs have historically been used. This has a completely rational justification - this way precipitation rolls down faster, and the roof is more likely not to leak.

    In some places, a dome was an alternative to a pitched roof. As an example, one can name such a traditional type of residential building for some peoples as a yurt.

    The dome, like the pitched roof, is quite effective in removing snow and water. In addition, it copes well with wind load - which is a serious threat to the well-known sloping roof with large overhangs.





    But the hot southern regions could afford to make a very small slope for water flow. For example, in ancient Greece, one-story houses with a flat roof with a slight slope, with an open courtyard and a pool into which water flowed, were common.

    However, this is all about the past. Modern building technologies make it possible to do what was previously considered irrational and even impossible. And flat roofs gradually penetrated all regions, increasingly crowding out other options. Take a look at any major city. And recently, in private houses, a flat roof is gradually replacing the traditional pitched one.

    Advantages of a flat roof

    This trend is explained by a number of significant advantages that this particular type of roof has. First, it is structurally simpler. That is, it takes less time and materials to build it. It's easier to insulate. And this leads to a reduction in construction time and significant cost savings. It is not surprising that in a market economy it is this type of roof that has become most widespread.

    And secondly, a flat roof is a potential opportunity to increase the usable area that you can use. After all, such a roof can be made exploitable - which we observe in numerous projects of modern houses with a flat roof.

    And this idea from beautiful projects has long begun to migrate into reality. This is not an architectural utopia, but something that you can implement in your own two-story house with a flat roof if you wish.

    Disadvantages of a flat roof

    Of course, the widespread introduction of just this type of roofing has a huge number of opponents who claim significant shortcomings of this solution.

    For example, it is often said that flat roofs still leak too often.




    And the lack of overhangs common for a pitched roof makes the facades of the building more vulnerable, which are not protected in any way from the destructive influence of moisture and due to this they quickly lose their appearance.

    Mention is made of an even greater snow load, which leads to the need to manually clean the roofs. But let's look at each of these disadvantages in a little more detail.

    Frequent leaks: who is to blame and what to do

    Unfortunately, this is a reality - a huge number of modern apartment buildings with flat roofs are in need of repair on a regular basis. And the inhabitants of their upper floors often suffer from water flowing along the walls and ceiling.

    However, it is not the type of roof as such that is to blame. Remember, other claims are often made to panel houses. Poor sound insulation, walls freezing in some places ... The thing is that during the construction of most of the modern housing stock, they relied not on quality, but on speed and quantity. And it was right - the housing crisis was very acute, it had to be solved somehow.

    But - yes - as a result, the residents of such houses now have problems. Including the current roof. But not because this type of roof, in principle, is not able to withstand the destructive effects of moisture. But because its installation requires professionalism, a neat approach and high-quality materials.

    However, there is another reason for the problems with leaks so common in prefabricated residential buildings. This is a failure to comply with what is called the "rules of operation".

    There are different types of flat roofs. For example, one on which you can walk, even plant grass there, organize recreation areas, parks, and swimming pools on it.

    If you undertake to study fashionable projects of houses with a flat roof, all this is often found there. But typical construction involves a different type of construction. The one you can't walk on.

    However, it is not always possible to fulfill this condition in practice. Roofs are cleared of snow, communications are installed on them, and so on. And all of these actions potentially lead to future leaks.




    Thus, if you entrust the installation of a flat roof to professionals in your private house and comply with all operating conditions, the roof will not disappoint you.

    The destructive effect of moisture: how to save facades

    So, critics of flat roofs say that the lack of large overhangs characteristic of a traditional pitched roof leads to the rapid destruction of facades. And, in general, it is difficult to argue - water can even affect mountain slopes, let alone brickwork.

    However, do overhangs really protect facades from moisture so well? Imagine slanting jets of rain hitting the surface of a wall at an angle. Roof overhangs take on part of them, it's true.

    But in fact, they really cover only a small strip of the facade from above. The larger the protruding part of the roof, the more this space will turn out. But it cannot be increased indefinitely.

    Thus, in order to protect the facades, not some special type of roofing is needed, but modern building technologies. For example, a frame house with a flat roof, lined with porcelain tiles or siding, will be extremely resistant to external influences.

    Snow loads

    This factor can be very significant in some regions. The layer of snow has a large weight, which additionally loads the floor. And if it does not survive, the consequences will be very deplorable.

    However, the design features of a flat roof according to the rules are calculated taking into account the possible snow load. Thus, if no fatal mistakes were made in the design and construction, the snow will not affect the house in any way, no matter what roof it has.

    Aesthetic possibilities

    Sometimes you can hear that rectangular boxes with a flat roof are uninteresting and ugly. Of course, those who say this have never seen modern houses with a flat roof, even in a photo, not to mention a personal acquaintance.



    It is no coincidence that this architectural solution is now at the peak of popularity. Styles such as hi-tech, minimalism, modern invariably prefer roofs with a slight slope. Because it allows you to make a more complex planning structure, embody previously unrealistic ideas, create expressive and unusual compositions. Such architecture can look very impressive and original.

    Modern low-rise architecture gravitates toward geometric shapes. The trend has found expression in the construction of houses with a flat roof. Such buildings are aesthetic, functional, allow you to usefully equip additional space. Unlike pitched surfaces, the slope of the top coating is no more than 3-5 °. This causes increased requirements for hydro and thermal insulation, precipitation removal, and structural strengthening. With proper design and selection of building materials, a house with a flat roof is not inferior in reliability to single and gable buildings.

    In the company "COUNTRY SEASON" you can order the construction of a private house with a turnkey flat roof. We implement standard projects, as well as carry out individual development of design, technical, regulatory documentation.

    Projects of cottages with a flat roof

    Finished projects of flat roof houses differ in the type of upper structure:

    • exploited roof - used for arranging flower beds, recreation areas;
    • unused - suitable for installation of antennas, solar farms, other technical objects with a relatively low weight.

    Modern flat-roofed houses are beautiful structures with trendy designs close to high-tech and minimalism. Buildings are equipped with bay windows, terraces, balconies, panoramic windows. For permanent residence, options with a boiler room are used. Car owners prefer dwellings with a built-in garage for 1-2 cars.

    On the site "COUNTRY SEASON" there are photos and approximate prices of one-, two-story cottages. To calculate the cost and buy a project, order a call back. We develop design, carry out individual design, build housing in all districts of Moscow and the Moscow region.

    Looking for beautiful flat roof house designs with photos and layouts? Our catalog contains many projects of thoughtful houses, among them there are those with a flat roof. This category is a real highlight of our catalog. Modern houses with a flat roof are in particular demand among wealthy people who keep up with the times, who are not afraid of experiments and innovative ideas in suburban construction. Not everyone likes the original designs of flat houses, many people think that such cottages are not functional and not beautiful, and living in them is not comfortable. However, this is not so, let's take a closer look at this type of houses. In the photo, they all have an impeccable appearance, to which we have already become accustomed when visiting foreign resorts, because most modern villas are made in this architectural style. Successful planning solutions in finished projects are not inferior to typical classic houses, but a large glazing area is available, due to the use of French windows to the floor. Some people are confused by a flat roof, how to care for it and clean off the snow in the winter. However, the coating is made of a PVC membrane, which lasts a long time and does not require special care, and the snow from its surface is melted by special heating elements. Buildings with a flat roof are very easy to build, especially if gas silicate blocks (aerated concrete) or large-format ceramic bricks (warm ceramics) were chosen as the building material. When choosing a project, consider your needs, the number of bedrooms, the presence of a garage and terraces, whether you want

    Often, in the construction of private houses, preference is given to a pitched roof, but there are also buildings with a flat roof, and as a result, very curious architectural objects are obtained. If a decision is made to equip this structure, then you need to be prepared for some difficulties. There are pros and cons of a flat roof, the nuances of its installation.

    Pros and cons of a flat roof

    It is worth noting from the very beginning that a flat roof for a private house is not a perfectly horizontal surface. It also has a slope, only a small one (from 1 to 5 degrees). The following main advantages of the roof can be distinguished:

    • the overlap of the upper floor will serve as a supporting structure for the roof;
    • the same height of the space under the roof will allow it to be used as a full-fledged room;
    • gives the house an original look;
    • the possibility of using the roof surface (for example, you can equip a summer terrace there);
    • simplifies repairs and makes them safer.

    The disadvantages include:

    • stringent requirements for the waterproofing layer of the roofing cake;
    • the need to install an internal drain;
    • high degree of snow load.

    From the above, it follows that a flat roof is a good solution, provided that all roofing work is carried out to a high standard and the requirements are taken into account.


    Basis for mounting a flat roof

    What will be the overlap of the upper floor directly depends on the structural features of the ceiling throughout the house. As a rule, it is performed using the same material as the ceiling between floors.

    The most common options are prefabricated or monolithic reinforced concrete floors, profiled sheet ceilings with metal support beams.

    An option with a wooden floor is also possible. The fundamental difference from the overlap between floors is the presence of a laid insulation and high-quality waterproofing.

    Roofing cake options

    The type of roofing cake is determined by the nature of its location and purpose. It can be performed in the classic version or made inverted.

    Classical roofing has the following composition: ceiling, concrete or expanded clay concrete slope, vapor barrier, heat-insulating material, roofing with a high degree of protection against moisture (mainly bituminous materials).

    In the inversion structure, the arrangement is different: overlap, slope, multilayer waterproofing, heat-insulating material, vapor barrier and, finally, the pressure layer. The latter can be made from concrete slabs, gravel, ceramic tiles, etc.


    The name of the inversion roof was due to the mirror arrangement of the layers of hydro and vapor barrier in relation to the insulation (unlike the classic version).

    This type of roofing is ideal for exploited roofs. However, the complexity of the technology makes such roofs a rare exception in the field of private construction.

    The technology itself is expensive, since the massiveness of the structure makes it necessary to create a solid floor of the upper floor.

    Bearing structures require detailed calculations at the design stage, and the layering of the cake brings with it significant costs.

    Below, only the classic version of the roofing pie will be considered, which is often equipped with modern houses with a flat roof.

    roofing material

    The material for the roof, namely vapor barrier, waterproofing, insulation and the coating itself, must be of high quality.

    Vapor barrier is performed by special membranes, not perforated films. It is undesirable to use polyethylene as a waterproofing, since the material does not have the necessary reliability.


    Insulation for mounting a flat roof is selected taking into account the snow load, as well as the load coming from people working on the roof during repairs.

    The insulation must be durable and resistant to a humid environment. It can be polystyrene foam, high-density mineral wool, expanded clay.

    The efficiency of the latter is not so high, therefore, when choosing it as a heater, it is necessary to achieve a large thickness of the layer being laid. This increases the load on the supporting structures.

    The coating is made from rolled materials: roofing material, linochrome, hydroisol, etc., and bulk mastics are also used. Roll material is considered the most optimal for use in the arrangement of a flat roof.

    Roofing technology

    Flat roof construction involves the following workflow steps. The slope of the roof, albeit small, is achieved by creating a slope.


    In this case, you can use bulk material (expanded clay), foam concrete (it is advisable to contact specialists), and a heater. From above, the slope is covered with a waterproofing layer, after which the process of laying the roofing begins.

    The next step is laying the first layer. A roll is rolled out, then it is heated with a gas burner and glued to the base.

    It is important to ensure that the sheets overlap each other and the material is applied to all vertical roof objects (parapets, pipes, etc.).

    Three layers of lining and one finishing layer are laid on a flat roof.

    The stage of laying the coating is a laborious process, especially if you want to use adhesive mastic.

    Overhead gutters, an internal drainage system are used for the drainage device.

    In the case when all the work related to the arrangement of the roof is done correctly, you will have an excellent opportunity to proudly declare the originality of your residential creation. And the photo taken of a house with a flat roof will join the ranks of original design solutions on the network.
