In Ukraine, projects of houses with a flat roof are fairly in demand. Our brother is more familiar with ordinary classic roofs, and there is a simple explanation. "The roof, that's it and the roof that would protect from snow and rain, which means that it should all drain and delay anything. If you make it flat, then where do you go natural precipitation? " - So many people think. In Ukraine, such houses are also uncommon. Here they are exclusive. So, let's try to figure out that the truth is, and what you need to really fear.

Project of the house with a flat roof - pros and cons

1. Cleaning. On a flat roof, snow and water can really linger. If it is made incorrectly and poorly, then all this will gradually leak into the house, and, even, may be pretty to upset the ceiling of the upper floor. Therefore, the design stage is very important on which the slope is calculated. Yes, yes, do not be surprised, it is the slope. Even the smoother roof must have at least a small tilt, which will not be visually visited, but which will be enough for water drain. More difficult in winter when snow lies on the roof. After all, he can linger even on the coolest roof, not to mention flat. He will melt in a thaw, then again freeze, as a result of which a solid ice crust is formed on the roof. And this is a high probability of leakage, especially in the spring. Therefore, the roof must be regularly brushed from snow. But for those whom the shovel is not hunting, you can install the "antiy" system, which will heat the snow and ice right on the roof.
2. Heat insulation. Classic roofs, thanks to the attic room, create an air layer, which is significantly insulates the house. A flat roof, as the attic does not form, does not have a similar interlayer and therefore it is necessary to warm it efficiently. She also needs good thermal insulation. The projects of houses with a flat roof initially must contain complete information about roofing materials and their quantity.
3. Easy installation. On the one hand, the flat roof is easier to make than a hollow, semi-unlighted, tent or twin. Here it is not necessary to rafters, no runs, no skates. Everything is extremely simple. But, on the other hand, the roof requires high-quality installation of the roof, whatever it flows and did not feel. In this regard, such a roof is much more complicated.
4. Application. The project of the house with a flat roof is good because such a roof can be inventing the application. But to do it, again, it is necessary at the design stage. A wonderful terrace may turn out on a flat roof. It is enough to make fires for safety. You can make a small canopy and put the sun beds. They will not harm too. On such a roof, you can even make a tennis court if the dimensions of course allow. Modern materials and development allow you to make a herbal lawn and plant plants. Such application is especially good in urban conditions, where every bush is on gold weight.

It turns out that projects of houses with a flat roof have a lot of advantages, and their entire unclaimed in the expanses of Ukraine is related to what we have later than in the West, new developments appear in the construction sector and new materials. Yes, and to teach people to work with such innovations. But it is time to change stereotypes and keep up with the times.

Projects of houses with a flat roof from DOM4M

The project of the house with a flat roof can be bought on the website of the company DOM4M. The price of such projects will not be more expensive than on projects of other houses, for example. It depends rather from the size of the house and its complexity, rather than on the type of roof. Of course, the more "frills" will be at home, and the more difficult to embody their reality, the cost will be more expensive. Therefore, houses with a flat roof can fit into different budgets. As they say, everyone in need and if possible.

How fast time flies! Has passed for 4 years from the moment I built my own hands unusual vacation home. There are many non-standard technical solutions in the house, which were previously practically not used in individual construction in Russia. First, the house is heated with, and secondly, the house has a flat roof.

From the very beginning of construction in 2012, I constantly stated that the flat roof is not for our climate (and for what?) That she will definitely leaks (why?), And indeed with such a roofing house like a transformer booth (poor Europeans, they have to live in transformer booths).

But most often I tried to prove that with flat roof It is necessary to constantly remove the snow (I wonder why?). Of course, if anyone wants - you can clean, no one forbids. But on houses with a flat roof there is no need to remove snow. For example, now I have on the roof there is a snow cover with a thickness of more than 80 centimeters! And somewhere there under the snow hid.

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

By the way, as it turned out, many do not know that the flat roof is not a plane in a direct understanding, and the surface with a slope of about 2-4 degrees (in fact, the roof is considered flat if its tilt angle is from 2 to 20 degrees). And on any flat roe necessarily there is a drainage. It is more correct for a flat roof to make inner drain, but you can do and classic external. At the time of the start of construction, I did not have sufficient knowledge to design and realize the inner drainage, so I made an external. The advantage of the inner drainage in the absence of pipes on the facade.

3. Summer 2013, just done. The flat roof is substantially cheaper than any scope (at a minimum because its area is 1.5 times less than that of scope). With her there is no loss of square and such a useless place in the house, like a attic. It is easier and easier to inspire - everything is in the same plane.

Let me remind you the construction of my roof cake (bottom up):
1. Collected-monolithic overlap with filling aerated concrete blocks - 250 mm;
2. Warming with extrusion polystyrene - 150 mm;
3. Warming and creation of a slope with the help of wedge-shaped plates of extrusion polystate - 0-150 mm;
4. Cement strainer - 50 mm;
5. Two-layer weld waterproofing (top layer with a sprinkler).

4. Another huge plus flat roof - she is not afraid of a hurricane. Look at the chronicles of hurricanes and how easily disrupts the coating and breaks the rafter system on classic shelter roofs.

5. In the summer of 2016, I graduated from all other work on the improvement of the adjacent territory and decided to do.

6. By the way, if anyone knows, then any concrete overlap The default has a carrying capacity of at least 400 kg on 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 is rare in reality when it is achieved, but it is obvious that any overlap has a huge reserve for carrying ability.

7. Another important advantage of a flat roof is that it has completely sealed seams. While on the pitched roof, the seams are not sealed and in the case of the scope roof it with snow and it will begin to melting down (due to insufficient insulation) - the scope roof will flow (especially in the place of the joint of two rods - endowes). Look at the neighboring houses with scanty roofing - surprisingly, they also lies snow!

Why does not flow flat roofing done on technology? Everything is very simple. Because it is insulated!

It is 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 whole building. If the roof is not insulated, or is not well insulated, then the heat will rise up, and the snow lying on the upper roofing carpet. At the occurrence of frosts, the lifting snow will freeze again, and during freezing, as it is known, water is expanding in volume. These numerous zero-freezing cycles will ultimately rupt the waterproofing (after 2-3 years) and the flat roof will begin to leak.

8. In the last century, during the construction of houses, they did not think about energy efficiency and energy savings, therefore, the heat insulation of the roof was not usually done. This led to the fact that the waterproofing of the roof was constantly destroyed and the roof flowed.

If the roof is warmly insulated, then she remains only one "enemy" - the sun and its ultraviolet radiation. But to protect against this and use waterproofing with a parcel, or with special additives (in the case of use). And the very effective method Protect waterproofing from destroying ultraviolet radiation - to make a lawn on the roof, fall asleep pebbles or lay a tile. By the way, a more promising waterproofing today is a polymer membrane.

Flat roofing is even easier than scope. With a flat roof you will never fall on the head of the snow and does not torment the drainage grooves. It is not necessary to clean the snow, and if there is a lawn, there is no need to follow the purity of the drainage gutters (all the water is filled through geotextile and they will not be bored with fallen leaves).

Therefore, a flat roof is the most sensible roof version, especially for the house from. The main thing is not to violate the technology and do not save on insulation.

And to clean the snow with a flat roof is not only useless, but also harmful - it is possible to accidentally break the sharp edge of the shovel waterproofing and the roof will begin to leak.

Most often, when designing private houses, scope roofs are used, but the cottages with a flat roof, as in the photo, are much less common. IN last years After appearance newest technologies And modern materials for overlapping flat roofs are possible to create effective waterproofing, despite such unusual form.

The presence of such a roof does appearance The private house is exclusive and original, since it stands out against the background of buildings with tent or scanty roofs.

The projects of cottages with a flat roof have their own characteristics, and their construction is associated with some nuances, since the roofs may be:

Advantages and disadvantages of flat roof

Flat roof provides property owner a number of advantages, including:

The disadvantages of the structural solution of flat roofs include:

• conducting installation with strict observance of the technology of their waterproofing and. The slightest violation of the rules due to negligence or negligence is completed by the roof flowing if atmospheric precipitations accumulate on it. Extraordinary roofing repair will cost considerable costs, and sometimes it is necessary to carry out a complete reconstruction of the cottage roof;
• availability B. winter on a flat surface large number Snow suggests (if the roof is planned to use) its regular cleaning, which can be performed only manually;
• in the process of snow melting on the waterproofing layer it turns out to be a significant load

Features of flat roofs

When a project of a cottage with a flat roof is developed, regardless of the number of floors in it, it is certainly taken into account the following features:

Creating a flat lightweight roof

If the cottage with a flat roof planned to build with a lightweight roof, it does not plan to operate.

The procedure for the construction of such a design is as follows:

As a result of the work produced, a flat roof is obtained, which refers to a lightweight type. It is fully entrusted with it fully, but it is not even able to withstand even a minor load. If you wish to equip on a flat roof a small place to rest, you need to build a roof in a completely different technology.

Construction of an exploited flat roof

When the cottages are design with a flat roof and a solid coating, it is assumed that the created roof will not be fed under the severity of the load (read: ""). There are several ways to build the operated coverage.

One of the easiest options is the laying of concrete slabs as overlapping. Bearing structures for this should have a significant margin of strength, in addition, installation is performed using construction special equipment. The roof, created from concrete slabs, must be insulated, but you can only perform such work from the inside of the room.

Another way is the construction of roofing overlap based on metal supporting beams - brass or foreign and chapels. Top laying board flooring made of sawn timber minimum thickness 22 millimeters, and on top of it pour a layer of ceramzit, which is at least 150 millimeters. The solid coating provides a concrete screed.

Most. in modern way The use of ceramic large-sized construction blocks is considered to be solid. They are placed on support beams, and they provide a roof along with mechanical strength good sound insulation and heat insulating characteristics. Among the advantages of such ceramic roofing blocks, it is impossible not to mention their excellent resistance to humidity. Before making a screed for such a roof, the belling of the clamzite is not required. The disadvantages of ceramic blocks include their high cost.

Build cottages with a flat roof of a solid type with styling of roofing membranes (optional). They provide additional waterproofing and improve the operational characteristics of a flat roof.

Projects of houses with a flat roof allow you to erect country houses by modern technologies. Their development led to the use of a variety of roof mounting materials. It should be founded with all the stages of designing such exclusive buildings.

Projects of houses with a flat roof allow you to erect country houses on modern technologies

Starting the design of the house with a flat roof, it is important to identify all its main advantages. Among the positive moments, during the construction of the modern structure, it is allocated:

• unique creative design, for example, house in the style of high-tech with a flat roof or other;
• savings on heating construction inside;
• the presence of additional square meters.

Highlighting a country house or cottage with a flat roof, one should be attached to the trends in the development of the design of Western countries. Style Minimalism or High-Tech: Here you can always feel the material benefit. The house with an exploited roof will be very convenient. At the same time, such a roof design allows you to improve the house with a flat roof, equipping a special platform for sports games on it.

The costs carried out in the process of designing houses or cottages with a flat roof are not too expensive. If winter on the roof of a flat type will remain a layer of snow, it will be a good insulator. Heating of this house will cost cheaper.

Despite the fact that for many it is acceptable to implement projects of houses with a flat roof, these options have their drawbacks. Set the flat roof should be taking into account the requirements for laying waterproofing. Among the main reasons why the owners of houses can blame such a design with any design, it is its flowing. This is usually due to the presence of small deviations in the technology or negligence builders. On the surface of the roof can accumulate water.

To completely eliminate flow, it is necessary to carry out a reconstruction that can be very expensive. The roof cleaning is usually carried out independently without the use of technology. After all, with the beginning of the melting of the snow, the layer of waterproofing design will begin to be exposed to a large load. As a result, the surface will be destroyed.

How to mount flat roof

Working out projects one-storey houses With a flat roof, it is important to consider the following highlights:

• the roof should not be completely flat, so it is necessary to take into account its tilt angle, equal to 5-15 °, otherwise this type of construction will be constructed only to collect precipitation;
• ideally, a flat roof must be replaced, since the presence of the desired slope is required for drainage.

The terrace or a gazebo with a flat roof is equipped with bulk building materials. Concrete stretch or polymers that have a fixed angle will also be required. This sheet material is called polystyrene plates.

Roof Square requiring smooth corner Roofs, assumes the presence of a carrier plane. The stage of the rally needs to be included in the project plan of the house. There are 2 types of projects country houses With flat roof, which depends on the features of the roof design:

• lightweight;
• operated.

Each of the specified species has its own characteristics that should be taken into account in the construction of the roof.

Holding a country house or cottage with a flat roof, should be focused on the trends in the development of the design of Western countries

Light roofing flat type

The facilitated version is a flat roof that does not provide for the operation of operation. It can be performed in any style, for example, High-tech. It should be erected in stages:

• laying the main beams (brusade material) is carried out on the bearing walls or to Mauerlat, fortified on them;
• fixation of beams laid in increments of 0.5-1.0 m is made to the base using anchor spills;
• on the beams, a solid wooden lamp consisting of edged board inch thickness;
• the membrane is stacked for waterproofing.

The main beams can serve as bars from wood, having a cross section of 100x100 or 150x200 mm, which is determined by the estimated weight of the roof. The doom is arranged without any holes. Laying the waterproofing layer should be multi-layered. All joints are sampled with the use of glue or scotch.

Creation of "Pie" flat roof

Specialists do not recommend saving money when buying and arranged the waterproofing membrane. This material cannot be replaced with a rubberoid that will not provide the necessary effect, and it is impossible to leave the house without a roof. With the arrangement of the insulation of the roof, polystyrene plates extruded or mineral wool. The heat insulator must be mounted on a layer of waterproofing carefully so that the slots are not formed. Even with the slightest inaccuracy heat insulation material Maybe over time, start skipping cold air.

When laying the insulation on the lattice from the bar immediately set outwards for ventilation, which will be an obstacle to the accumulation of condensate. This will save the thermal insulator in dry form. Good insulation It is a grainsite, which is popular when creating projects of single-storey houses with a flat roof. This layer should be about 100 mm. At the final stage of the installation of the roof, it is necessary to carry out waterproofing protection. The modern market of building materials offers a membrane. Lightweight plane roofing is not able to resist strong loads, so in such conditions it is impossible to operate.

Flat solid roof

A private house having a flat solid roof should not be fed, so you can use the entire free area. At the same time, any cracks should not be on the roof of the house. To create a flat roof, it will be necessary to own special technologies. This should be attached to certain efforts. It is possible to equip the solid roof in several ways:

1. Using concrete slabs as overlaps, taking into account the fact that the supporting structures are sufficiently strong, withstanding the load.
2. Using metal support beams, allowing to produce a roof overlap, will require brand or dual-level beams, as well as channels under No. 14-16.
3. Using blocks from ceramics stacked on support beams, which ensures solid coating.

The first method requires the use of heavy machinery. This type of roof must be insulated, which is made from the inside of the room. On the supporting beams made of metal, laying of the board of the flooring, consisting of a thickness of 22 mm thick at least one. Then the ceramzit layer is poured with a thickness of at least 150 mm. At the last stage of the solid coating, you can go to laying a concrete screed.

Most in demand in modern construction 3 way. Ceramic was used for mounting a solid roof roofing materials. They can be immediately laid on supporting beams, which should ensure the strength of the roof. This material is capable of keeping warm. It has excellent soundproofing characteristics.

Ceramic roofing blocks have the main advantage, that is, moisture resistance. The fill of the screed is made without pre-floating the clay. A significant drawback of the material consists in its high cost. Additionally, a membrane for a roof is placed on a solid roof roof, allowing to improve the performance of the material and reinforce the waterproofing layer.

When choosing a project, it is important to remember that the plane roof is quite sensitive to the waterproofing layer. The scope roof hides various operational shortcomings. Deciding with a project for the construction of a house with a flat roof, a further action plan should be developed, purchase qualitative materials. It is necessary to discuss in detail with the builders all the conditions and requirements. As a result, a non-standard building will be erected, for example, in the style of high-tech, corresponding to European standards.

Houses of houses with a flat type roof

If the search for the cottage project turned out to be unsuccessful, then it is possible to design it with the help of the team of specialists. This fascinating process allows you to see each design stage, which is the beginning of which the general concept is accepted. This process ends with the creation of a completed image, thought out to the smallest detail. Here it is necessary to take into account not only your own wishes, but also the features of the countryside landscape.

Any project catalog ensures the use of various architectural techniques. This entails the use of certain methods or technologies. Development of projects that allow erection of two-storey or one-storey houses With a flat roof, requires to take into account a few moments:

1. The conditions of the climatic belt, where the object is located, which should affect the size of the thickness of the heat insulator used or its absence.
2. The circuit in the roof may have a removal either, from which the applied method of water leads is depends.
3. The functional destination of the terrace with the roof, which can be a resting place for people, parking for the car, small garden For planting crops.

The nature of the construction is influenced by the choice of type roofing designwhich can be:

• traditional: a layer of waterproofing is located above thermal insulation;
• inversion: layers are located in the reverse order.

If the process of operation of the roof involves the use of hydro and heat insulators, then they should perceive the load. It can come from people either transport.

Roofing houses with an operated roof of a flat type can be made of PVC membrane. It has a long service life and does not require special care. For cleaning snow from its surface, heating elements are used.

Direct way to choose projects two-storey houses or single-storey buildings - a specialized site. They are easy and convenient in construction, especially if the material used is a gas silicate (aerated concrete) or a large-format type sample, which refers to warm ceramics. Choosing a project of the house, you should consider the needs, the number of rooms of a certain purpose, the presence of a garage room ,.

ATTENTION, only today!

Not so popular like scanty.

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

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

And on such a roof, you can equip additional areas that are especially in summer time will be good place For recreation and pastime.

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

The advantages of flat roof are:

• Primary such roof perfectly performs building protection functions from external influences;
• not required great effort and costs (material, physical) for its construction;
• long service. The flat system does not require expensive maintenance with the right installation of all major and additional elements of the roof;
• the ability to install additional amenities on the roof, up to the pool and garden sites and saunas;
• good thermal insulation indicators.

To negative factors of home improvement with flat roofs include:

• Accumulation of snow or rain puddes on the coating;
• there is a risk of freezing or forming a blocking of the inner drainage;
• mechanical cleaning of the external layer required from snow and leaves;
• the inability to use leaf or piece species;
• there is no possibility to check the condition of roofing pie (in particular the insulation)However, drainage systems and ventilation moves are much easier to check.

The lack of an attic floor in the presence of a flat roof design may be worth or disadvantage depending on preferences.

Types of flat roofing

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

The varieties of flat systems include:

• Exploited. The main requirement for this option is the rigidity of the base in which important condition is the preservation of the integrity of the waterproofing layer. The base can be made of a concrete screed or. Requirements for material strength and its resistance to static and dynamic load. The most common external coating for a flat design is paving tile which is installed on additional stands or sand pillows;
• non-exploitable. Considering the fact that the roof of this type is designed to perform exclusively the protection functions of the building from external factorsThe special requirements for the stiffness of the insulation layer or the strength of the base is not. The arrangement of such a roof is much easier than the construction;
• classic. When arranging a classic type on the base, a vapor insulation layer is placed in order to ensure the protection of the insulation (minvati or foam) from moisture. Waterproofing provide bituminous materials;
• inversion. The roofing structure involves the location of the waterproofing layer at the insulation, which prevents moisture accumulation in the insulation. At the same time, the temperature differences that destroy the waterproofing are minimal under the insulation.

In order to make a house project with a flat roof, you need to think over the coating option in advance.

Where to start design

The purpose of the design of any roof lies in proper choice and calculation of quantity essential materials , as well as in a clear expression, what load will carry all the elements involved in the design.

The project is a plan. In the project plan, each stage of work should be displayed.

The project is most convenient to perform in a special program.which will help not only display the future structure, but also help calculate the size of the materials, their load.

Design is made by steps:

• Sketch of the roof is performed. At this stage, the color is approved, the geometric shape of the future roof, with the indicators of the roof size, the load of materials is calculated taking into account regional atmospheric influences. It should be remembered that snow load on a flat roof is more significant than on pitfall structures;
• calculation of the cross section of beams and lengths of the boards rafter system . It is very important to correctly determine the pitch of the crate, since it is precisely the rafter design withstands the entire load;
• a schematic drawing of the roof is performed. At this stage, the location of all additional elements of roofing structures is taken into account.

After performing the drawing, the roof is processed by the preparation of the estimate - Costs for materials, structural elements and tools (if necessary), which are required to fully perform work on the arrangement of a flat roof.

It is not necessary to get involved in the decorative features of these elements - it is most important to pay attention to their functional features.

Lightweight flat roof

The flat system of lightweight design is installed in the regions with a minimum amount of precipitation.

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

However, there is some features of its construction:

• At the stage of installation of supporting beams, it should be noted that they will hold the entire design. Secure them need through anchors. The cross section should be calculated taking into account the maximum burden of snow;
• the doomed laid on the beams should be solid, no gaps, more than 2.5 cm thick;
• waterproofing, placed on the crate, stackedwhich is bonded by a hot way. The edges of the film should go beyond the roof line;
• on the waterproofing layer, a solid insulation without gaps. The locations of the docks close up by mounting foam;
• further place OSB plates or waterproof plywood board.

This is how the cake of a lightweight system looks like. All layers are bonded by anchors and are coated with an outer layer of waterproofing.

Operated flat roofing

The flat roof that performs additional features, except for protecting the building from cold, wind, snow and rain.

The main advantage of such a roof is the possibility of arranging free space at its discretion: Install the platform for recreation, terrace, court, bath and even pool.

Such roofs are ideal for both cottages and a cottage.

In order for the necessary buildings on the roof to be reliably equipped, it is necessary to take care, first of all, the strength of the foundation.

• thermal insulation;

Conclusion

Thus, there are several options. Special attention in the construction of a direct design should be given to ensuring ventilation and the creation of conditions in the design to prevent moisture.

The originality of the straight roof can be in the arrangement on it additional areas for recreation, and this option should be considered in the process of creating a project. If everything is correct to calculate and use high-quality materials, such a design will not give up the scope options.
