Residents of the post-Soviet space staunchly associate flat roofs with multi-story buildings. standard houses. Modern architectural thought does not stand still, and now there are many solutions for private houses and cottages with flat roof, looking no less interesting than pitched structures.

Peculiarities

One-story house with a flat roof has a stylish and modern look. Basically, such designs are stylized in a special way, choosing the directions of minimalism or hi-tech. Traditional styles they will not be suitable for buildings with such a roof, since such roofs have only recently been developed properly, therefore, any of the classical trends will look ridiculous here.

Of particular interest is how exactly the roof will be used: either for its intended purpose, or as an additional open tier-terrace. It is necessary to decide on this issue in advance in order to competently draw up a project plan.

Materials

For the construction of 1-story cottages with a flat roof, they are used various materials, however, it is worth keeping in mind that not all of them are suitable for the Russian climate. In winter, a large amount of snow falls over almost the entire territory of Russia, which greatly increases the load on a flat roof. Therefore, you cannot make walls from light and insufficiently strong materials. In this regard, popular frame buildings will not be suitable, but there is another prefabricated option.

Materials for floors and walls differ. If almost all durable types are suitable for walls (monolith, brick, wood), then for the roof you will have to choose the type of building material more carefully.

Reinforced concrete slabs

Hollow or flat reinforced concrete slabs used in modern construction for floor coverings. They are strong enough to support the weight of a flat roof.

Plates have many positive qualities:

strength;
durability;
good sound and heat insulation characteristics;
speed of installation;
resistance to corrosive phenomena.

The main disadvantage of the material is that it is produced only in standard sizes, this must be taken into account when creating the project. Reinforced concrete slabs are suitable for floors only in a house that has a reinforced foundation.

Corrugated sheet

For floors, a special corrugated sheet is used, which is called load-bearing. Like the previous option, it is perfect for installation as a flat roof. Load-bearing corrugated sheeting is very popular mainly because of its low cost. This material costs significantly less than all the others. However low price did not prevent him from establishing himself as durable and universal material, which has an excellent ability to withstand the heavy loads that a flat roof is subjected to.

Load-bearing corrugated sheeting weighs much less than reinforced concrete slabs, therefore it is optimally suited for creating flat roofs on average climatic zone with little rainfall in winter.

Monolithic concrete

This material is used for floors quite rarely due to the complexity of installation. Here you first need to prepare the mixture, after which you can fill it. Only true professionals in their field can do this. However, it should be noted that monolithic concrete It works well as a flat roof, but only if the manufacturing and installation technology has been fully followed.

Modern one-story houses with a flat roof are not usually built from traditional materials. For this purpose, modern developments are best suited, which can withstand both harsh winters and summer heat. At the same time, they are easy to work with, and the construction itself does not take much time.

SIP or sandwich panels

In the catalog of every self-respecting construction agency There is standard projects one-story houses with a flat roof made of SIP panels. Please note that it is best to order cottages made from this material. Construction requires special technology, so it can be difficult for a beginner to work with sandwich panels.

Speaking of virtues panel houses, one can note their low thermal conductivity and high noise insulation characteristics. Construction costs much less than using brick. At the same time, abandoning the pitched roof also plays a significant role.

Flat roof

We are all accustomed to seeing flat roofs only multi-storey buildings Soviet built. There is an opinion among many that such roofs are boring, and a real house should only be equipped with a pitched roof. In the light of recent architectural developments, this belief can be argued, especially if we remember the many advantages of such roofs.

It is impossible not to make a reservation that one-story houses with a flat roof can only be stylized in a modern direction. The flat roof itself looks futuristic, and you need to use this free space.

Advantages

There are many benefits of flat roofs.

Easy to install. The construction of a flat roof can be completed in record time.
Reliability. If you organize the roof in the right way, it can withstand a lot of weight. Moreover, if something happens, repairing such a structure is much easier than repairing the rafter system.
Excellent thermal insulation. Regardless of what type of flat roof structure was chosen, it will perfectly retain heat inside the house.

Cheapness. Compared to pitched ones, flat structures are much cheaper both in terms of materials and time consumption.
Easy to install equipment. Antennas, air conditioners, and various service communications are much easier to locate on a flat surface than on a slope.
Interesting view. If the house itself is decorated in the style of “minimalism,” then a laconic roof without a slope will perfectly complement the overall look.
Additional area. If desired, the roof can be strengthened and used to organize space for a playground, garden or recreation area. Some even make a swimming pool here.

Flaws

There are not many disadvantages, but they still exist.

No matter how good the roof is, there is always a chance that it will leak. In the case of flat design the risk increases many times over, because it is subject to heavy loads due to the fact that the snow does not roll off.
If you plan to use the lid for your needs in winter period, snow and ice will have to be cleared off manually.
The construction of a flat roof must be carried out in full compliance with the technology, otherwise there is a risk that it will leak or will not withstand the loads and collapse.

Varieties

Pitched roofs are divided according to several criteria, including the method of use and the type of installation of materials. As a rule, the name of each of the characteristics speaks for itself.

By method of use

Roofs can be used or unused.

Used roofs are those that are used not only as roofs, but also as additional space for spending time. Reinforced systems are used here, allowing not only to place heavy equipment on the roof, but even to organize a “green corner” here, planting a lawn, flowers and even trees. Equipping a structure of this type costs quite a lot, and it is important to factor into the project in advance what weight load the roof will be subject to.

Unused roofs are much cheaper due to the fact that they do not need to be additionally reinforced and equipped with waterproofing. The only thing you need to pay attention to is the snow loads to which the roof will be exposed in winter.

By type of installation of materials

There are classic, inversion and breathable roofs.

Classic types are usually used when designing unused roofs. This is due to the fact that they have a lower load resistance coefficient. Moisture or mechanical stress can be detrimental to these roofs.

The layer layout looks like this (from top to bottom):

top surface material (waterproofing);
bottom welded material (waterproofing);
screed (if provided);
insulation;
vapor barrier layer;
overlap

Thus, unprotected waterproofing layer quickly becomes unusable.

The inversion roof looks exactly the opposite, as can be understood from the name:

ballast (gravel, crushed stone or other heavy material);
vapor barrier;
hydrophobic insulation;
waterproofing;
protective substrate (primer);
overlap

Such flat roofs have a long service life and are optimally suited to the roofs in use.

Both classic and inversion designs can be breathable. They are equipped with aerators or deflectors to provide additional ventilation, because there is no gap between the flat roof and the house, as is the case with pitched roofs. This leads to insufficient air exchange, so organizing ventilation system so important.

Project

When designing a one-story house with a flat roof, it is extremely important to pay close attention to the type of roof. Here the roof is the most important component. Russian companies have been engaged in such design for a short time, so contact only trusted agencies.

House projects

Projects of houses with a flat roof

Country or country houses with a flat roof are attractive architectural solutions that suit customers with different needs and budgets. Despite the fact that pitched roofs for cottages are traditionally very popular in Russia, today the choice is increasingly being made in favor of originality. The flat roof not only looks exclusive and modern, but also perfectly performs its main functions. When used correctly, it reliably protects against precipitation and provides good heat and sound insulation. The Proekt-Shop online store offers large selection projects of houses with a flat roof. 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. This height difference is necessary to drain rain or melt water. If it is missing, drainage of another design is provided (for example, a drainage system). When choosing a cottage project with a flat roof, you must take into account that such houses have a number of operational features. For example, in winter snow may accumulate on them: it must be promptly removed 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.

Advantages of a flat roof

Aesthetics. 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 become excellent choice for those who value uniqueness in the design of the space around them.

Economical. 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. Projects of houses with a flat roof are suitable for those who want to arrange a comfortable space for relaxation under open air. 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.

Variety of flat roof cottage projects

In the Proekt-Shop online store 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; frame buildings are also popular. Projects differ from each other in terms of total and living space, number of rooms, and the presence of a garage and terrace. When choosing suitable option the number of family members is taken into account, the need for arrangement of additional premises: work rooms, playrooms, gyms etc. The Proekt-Shop online store offers a large selection of designs for one-story houses with a flat roof. As a rule, these are options for compact buildings that are suitable even for small areas. For placement additional rooms Attics can be used. The range also includes projects two-story houses with a flat roof.

Stylistic features of cottages

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

hi-tech,
constructivism,
minimalism,
cubism, etc.

This external design buildings are often combined with the use innovative technologies when installing engineering systems, such as solar panels. In addition, the design interior spaces houses are also often designed in high-tech style.

In recent decades, there has been a noticeable leap in the quality of implementations of private country houses and residences. People's taste preferences are improving, construction technologies are developing, utility networks And finishing materials. Thanks to this, modern architecture becomes freer and bolder, and everything appears more projects houses and cottages with flat roofs.

When designing houses with flat roofs, the architect has much more freedom in creating a volumetric-spatial composition compared to designing houses with a pitched roof. The volume of a building can be very simple and concise, or quite complex and multifaceted, and the visual image depends only on the general concept and is not limited by any style features.

There are several variations of the architectural expression of a flat roof:

No roof overhangs. With this option, the wall of the building turns into a parapet. The resulting simple cubic volumes can be used to create a volumetric-spatial composition of any complexity.
With roof overhangs. In this case, the floor slab extends beyond the external walls buildings. This could be a small canopy or a canopy over the entire terrace. The rhythm of the clear horizontals of the canopies creates a very dynamic and free composition. Thanks to the roof overhangs, the volume of the building is not limited by the contour of the walls, which creates a feeling of lightness.
Combination of cubic volumes and horizontal overhangs. As a result of the combination of two techniques, we get difficult game volumes and horizontal planes, which makes the composition dynamic and filled with details.

Advantages of houses with flat roofs

When comparing house designs with flat and pitched roofs, we can highlight several objective advantages in houses with a flat roof. Thanks to flat ceilings, the interior spaces are geometrically correct and clean, there are no awkward corners and ceiling slopes, as in attic floors houses with pitched roofs. The ceiling height is chosen to be optimal for the given scale of the premises, while in houses with pitched roofs there are areas with too low or too high a height. Thus, in cottages with flat roofs, the entire designed volume of the building is used as efficiently as possible.

As a rule, the second floors of houses with flat roofs are smaller in area compared to the first. Thanks to this, it becomes possible to create exploitable roofs on the second floor. You can play out various scenarios for using open spaces, diversifying your time in country house. In addition, terraces visually increase the interior space of the premises, being their natural extension.

Drainage in house projects with flat roofs

There are several developed solutions for draining rainwater from flat roofs. Several methods can be used in one house, depending on the architectural features of the building. It is most advisable to use organized internal drainage, when water is collected from roofs and terraces into funnels, and then through a system of drainpipes located inside the house, it goes into the storm sewer.

There are two options for external drainage. In the first, water is also collected by funnels, but only in this case drainpipes are located outside the building and go down to the ground along the facades. In the second option, the water is drained through a parapet funnel, representing horizontal pipe, built into the parapet.

And the option of unorganized external drainage from canopies and unused canopies is possible.

Operation of houses with flat roofs in winter

In our climate zone, cottage owners must be prepared for the fact that in winter there is snow on the roofs and terraces. If all construction technologies are followed, this does not pose any danger to either the building structures or the coating materials. Whether to clear snow or not is the choice of the home owners. When developing a structural design for a house, all possible loads are taken into account, including snow loads, taken according to climatic standards for a given region. The most reliable construction technology suitable for the implementation of houses with flat usable roofs is monolithic frame. In this technology, reinforced concrete is cast directly on the construction site. monolithic frame building, consisting of a foundation slab, columns, pylons and floor slabs. The walls are made of lightweight block materials. Whole monolithic ceiling, cast using hydrophobic additives, is in itself reliable basis, resistant to moisture penetration. A roofing cake with a final layer of waterproofing is laid on top of the slab. There are several types of modern waterproofing materials, the choice of which depends on finishing coating terraces. If, according to the project, the terrace is finished with porcelain stoneware, then under it they apply cement waterproofing. If it is expected terrace board on adjustable supports, you can use either roll waterproofing, or a membrane. Any of these types of waterproofing when correct installation provides reliable protection roofing pie from moisture.

Design of houses with flat roofs in the architectural bureau of Ilya Eliseev

The architectural bureau of Ilya Eliseev is engaged in individual design and construction of houses and cottages with flat roofs. We work in this architectural direction, as it corresponds to our aesthetic preferences and meets all the requirements necessary for living in a country house. Over the years of designing and implementing houses with flat roofs, we have accumulated a sufficient amount of knowledge and skills to create projects of the highest class. At the stage of developing a house, we think through everything in detail building structures, technological units, wall and floor pies, as well as the installation of utility networks, so that the process of operating the house is as comfortable as possible and does not require increased attention.

Buildings with a flat roof look original and are practical, especially in the cold season. All the pros and cons of this option. One-story, two-story, wooden houses in high-tech style and minimalism. We'll look at everything in more detail later in the article.

Pros and cons

The main advantages of this design are the following factors:

efficiency – triangular roof the area is much larger; its construction requires more materials;
time- for construction flat roof it takes less time, which is very valuable when building houses, especially if they are built from scratch;
safety for construction workers– it is difficult to fall from a flat surface, they will not have to provide themselves with insurance, build protective structures that require time and money;
ease of use– if you find a hole or need a routine inspection or repair, it will be easy for you to climb in for inspection;
practicality– many exploit flat surface in full, they make it into a flower greenhouse, a greenhouse, and use it to install equipment.

Designers classify such designs as minimalism, which are still in fashion, so your living space will be in trend.

Among the disadvantages are:

impossibility of rolling snow in winter;
the creation of special gutters and their regular cleaning are required;
To prevent water from stagnating, you will have to install humidity control systems.

Those who were not afraid of the design flaws tried to install it for themselves and were not disappointed. Any building requires care and maintenance, so the need to remove water and snow is not terrible.

How to make a flat roof on a square house?

When planning the construction of a structure for a square building, you need to immediately decide what type it will be. The complexity of the work done will depend on this. Choose one of the options:

not in use;
exploited.

It is easier to make a flat roof that is not in use, if you want to reduce costs, it is better to choose this option. To do this you will need to install beams on the walls. frame house so that the distance between them is from 50 cm to 1 m. Construction pins are used to fix them.

After fixing the beams, sheathing of boards is performed. Typically, those with a width of at least 3 cm are used. They need to be laid tightly so that holes do not form; defects at the beginning of work will make the entire structure fragile.

A waterproofing membrane is installed on the finished sheathing, fixing the material with either construction tape or glue. Then thermal insulation and waterproofing are formed. This is a short description of the technology that allows you to make a flat roof on a square structure.

The main difference in the construction of a roof structure that is not in use and one that is in use is that in the first the waterproofing is located above the thermal insulation, and in the second it is the other way around.

Projects

After determining what the structure will be, whether non-operational or operational, a plan or project is drawn up. The main goal of this stage is to calculate the loads that will be exerted on the building. On the basis obtained, you can calculate the amount of materials required.

If you do not have experience in constructing roofs, it is better not to create the project yourself. This task should fall on the shoulders of professionals who can take into account all the nuances. Many construction companies offer developed programs that allow you to select a project to suit your ready house or completely new, when built from scratch.

The given diagram of how a flat roof is made is difficult to implement for a person who does not have the skills, so it is recommended to contact one of the available companies. Their work on creating the project will include:

drawing up a sketch of the entire building;
calculation load-bearing structures– experts calculate the number of beams, the distance between them, and other special structures of the sheathing;
creating a plan-scheme.

The final plan is an important part of the design. When creating it, all the nuances are taken into account, additional elements roofs. Consider the location and quality of the following parts:

junction nodes;
cornice (to protect walls from flowing water);
funnels for collecting water;
aerators – for removing water vapor;
lightning outlet;
drainage

Single storey

This option is suitable for a small family. The one-story building looks compact, there are no extra rooms, most of them belong to minimalism. A flat roof that also goes with this style would be suitable.

A triangular roof gives a one-story building volume and visually enlarges it, which often looks ridiculous. Flat - on the contrary, it emphasizes the neatness of the building. Among the large number of one-story building projects offered by many companies, country house options are also in demand.

If summer cottage plot small, you have to save space without cluttering it with unnecessary building elements. Many people decide to use the option with a usable roof for their dacha, placing a terrace, flowers, even a greenhouse on it. Because of small size The roof of a one-story house can be strengthened so much that furniture can easily be installed on it: tables, chairs, sofas, cabinets.

Advice

If you want to install a pool on a one-story building, you need to discuss this in advance, when you start designing. In such cases, particularly powerful reinforcement and a special waterproofing system are required.

Two-story

Such options are suitable for large families, so that everyone feels comfortable, it is important for them to have their own space. It is better to build a two-story one than a long one-story one. This saves materials, money, and costs.

As a rule, in big family– great needs, everyone requires their own conditions for comfort. Some people want to enjoy relaxing in the pool, some want to plant their favorite plants, and some want to have breakfast and dinner while enjoying the view of the sunset. A two-story building with a flat roof will provide the opportunity to implement any ideas.

If the weight allows, the foundation and wall structure are strong, you can organize an entire beach on the roof. To make it comfortable in the heat, canopies are made around the pool to create shade. You can also use plants for this purpose; many prefer decorative ones.

Another popular option for using a large roof of a two-story structure is arranging a sports ground. Not every sport is suitable for playing at altitude, but for most it is possible. Many people install a tennis court, but it needs a sufficient area, otherwise you will have to run far for the ball.

Roof-mounted exercise equipment is especially in demand. Treadmills, orbitreks, other fitness devices that are located in the open air - good opportunity play sports on outdoors. However, given that they run on electricity, a cover must be installed to protect them during rain.

If you plan to use the roof for active recreation, you need to take care of safety by installing sides.

Hi-tech

The high-tech style has been relevant for several years now. Its connoisseurs prefer to adhere to the desired design not only when decorating rooms inside, but exterior finishing buildings. The main features of the style are smooth surfaces and textured finishes.

High-tech elements are not suitable for creating a cozy, homely, modest environment; if you prefer old-fashioned home design options, it is better to avoid this. Initially, the style was used only for offices and was considered official. Decades after its invention, it began to be used for residential premises, and there were immediately many fans of such rigor and minimalism.

High-tech is focused on demonstrating existing equipment, so modern exercise equipment and other equipment on the roof will look appropriate. This is not a modest style, so it is more often used for large two-story houses. If it is used to decorate a one-story building, it should look large.

Another high-tech feature is a lot of artificial lighting. Both small decorative lanterns and large main light sources can be installed on the roof. In order to strictly follow the rules of style, lamps must have a characteristic geometric shape.

The walls and roof are usually plain, but the colors should be bright and harmoniously combined with each other. Suitable shades are beige, light gray, and metallic. Suitable for harmony with them dark colors. If they have walls, then the roof should be dark blue, gray, burgundy, emerald, and other bright colors.

It cannot be said that houses with a flat roof are so common in our area. Still, we are more accustomed to seeing classic gable or multi-slope roofs. It is believed that houses with a flat roof look exclusive, even eccentric, and speak of their owner as a great original, a modern person who thinks outside the box.

By and large, “flat roof” is a rather arbitrary name. There should always be a slight but obligatory slope. Otherwise rainwater or water will accumulate on the roof after the snow melts, which will ultimately lead to serious troubles and costs for repairing not only the roof, but also the interior.

In addition to its direct functions - thermal insulation and protection of the house from precipitation - a flat roof can be used as an additional recreational area.

Let’s try to figure out how appropriate it is to choose a house design with a flat roof in our area. To do this, you need to imagine the advantages and disadvantages of this type of roofing.

Advantages of a flat roof

A flat roof allows you to optimize costs. It is smaller in area than any pitched roof. This allows the developer to save significant amounts on materials.
Simple form roofing significantly reduces installation time.
For the same reasons, repairing and maintaining the flat roof of an already constructed building is incomparably easier than in houses with pitched roofs.
But the most important advantage of house designs with a flat roof is the additional usable space that the home owners can use at their discretion. Some elements of engineering systems, for example, ventilation and air conditioning systems, can be placed on the roof of such a house. Or you can install solar panels.
But most often the space of a flat roof is used as additional zone comfortable rest. Here you can equip a solarium or a place for sports. By the way, there are even projects that make it possible to equip a swimming pool. The roof garden looks very impressive. Modern technologies allow you to pave the roof with paving stones. And in combination with a lawn and decorative trees, comfortable wicker furniture, garden gazebo with a fireplace, this place will become the center of a family holiday.

Naturally, like any roofing system, a flat roof has its disadvantages

More careful design and installation of the roof will be required, otherwise retribution in the form of expensive interior repairs is inevitable.
You will also have to pledge additional costs for the organization internal drains.
There are certain inconveniences associated with maintaining a flat roof. Firstly, constant monitoring of the moisture content of the insulation and the tightness of the roof is necessary. Secondly, there is always the possibility of clogged or frozen internal drains. Thirdly, in snowy winters there is a risk of leaks due to large accumulations of snow. But this disadvantage can be easily circumvented if you install an Anti-Ice system on the roof. True, this leads to additional costs.

Project of a house with a flat roof: is it worth doing?

It can be said quite definitely that with careful design study and competent work builders, it’s worth it to build a house with a flat roof. Ultimately, you get original housing with additional square meters usable area and save money on construction work and materials. And the Dom4M company hopes that you will live in comfort for many years comfortable home, built according to our design.
