For many, flat roofs are associated with urban areas. high-rise buildings, faceless and monotonous. But we are ready to surprise you! A flat roof in a private house will be a pleasant discovery for you if there is not much snow in your area, but the winds are strong enough. The fact is that in winter all snow accumulations from such a roof will simply be blown away. And most importantly, none strong hurricane will not be able to break the roof, which simply does not exist! And before you opens up a whole ocean of possibilities that now you can build over your head: a cafe, a dance floor, a mini-garden and even a whole greenhouse!
The main thing is to know about all the intricacies of building houses with flat roof, and everything will work out. And now we will reveal all the secrets.
- Such a roof is much smaller in area than the most gently sloping pitched roof. And this is saving on materials.
- Such a roof is being built much faster than a gable roof, and even more so a hip roof.
- Comfort and safety of all rafter works. You still need to manage to fall from such a roof!
- Convenient subsequent repair and replacement roofing.
- Unlike a gable roof, the dismantling of the old flat roof is usually not needed - this is additional waterproofing and protection. The new pie is made exactly like the old one, which saves a lot of time and effort.
- The ability to use the roof as an additional useful area where you can set up a flower garden, make an open terrace and even build a greenhouse.
- The ability to install transparent roof elements (with careful waterproofing), and thus make a view of the night sky.
- Possibility to build a house of laconic architectural form. Minimalism is at the height of fashion!
And now for the pros and cons:
- Such a roof generously accumulates snow in itself. After all, now he has nowhere to roll, and the snow itself often causes leaks.
- On especially generous days, the snow will have to be removed mechanically, which often damages the roofing.
- The structure of the roof is becoming more complicated: now we need gutters, which, in addition to everything else, are clogged.
- The difference is that water drains from the pitched roof rather quickly (and it happens that it does get into the under-roof space). But on a flat surface, it generally stands!
Insulation moisture control and general condition roofing should be regular. - But, despite the fact that for its arrangement building materials you need much less than for a pitched roof, a flat roof in terms of installation is much more complicated. Let's just say, there are a lot more different subtleties and nuances that are important to know about.
That is why many have fair doubts about the reliability of such a roof. But the European and overseas experience of private residential buildings with a flat roof is successful, and therefore you can safely get down to business.
Consider only such points:
- There is much more snow in Russia than in warmer European countries.
- Worse than snow a big difference summer and winter temperatures, which not all foreign roofing materials are designed for.
And here technology is everything!
What is a flat roof?
So, what acts as the supporting base of a flat roof:
- Reinforced concrete slab.
- Roof sandwich panels.
- Reinforced steel sheet.
And thanks to the fact that they learned to make a flat roof “breathable”, i.e. with internal ventilation, it has now become possible to use completely non-breathing waterproofing - roofing felt like it.
Any roof that we call flat, in fact, still has a slight slope: to one side or purposefully towards the drainpipe.
Here is the simplest example of a flat roof for a private house:
Types of flat roof: unexploited and inverted
Cheaper, of course, cost unexploited roofs. And exploited, which are correctly called "inversion", include additional materials.
A separate type of flat roof of a residential building is exploited. Those. the one on which people will walk and what objects will stand. This is the same garden, or sports ground, or summer cafe. All this creates considerable loads on the roof, and therefore its device is already different from the one that is intended only to protect the house from precipitation.
So, the main difference in the arrangement of traditional and inverse roofs is that in the first layer of thermal insulation is under the waterproofing, which is quite logical, and in the second - above it. But in the second version, the waterproofing is more protected from ultraviolet rays and temperature extremes. This design is more durable and functional: you can safely arrange a lawn or lay paving slabs on it.
And now in more detail.
Unexploited roof: standard pie
But a person can also occasionally climb onto an unused roof - for the same repair, for example.
Those. in a traditional flat roof, the top layer is waterproofing, and it is she who is subjected to all mechanical and thermal stresses.
Its separate type is a roof with a pressure layer, which is designed for the fact that a person can walk on it from time to time:
Inversion Roofing: Reverse Pie
The standard slope of an inverted roof is 5-7%. The inversion method assumes that the thermal insulation layer is already located on top of the waterproofing, which now also serves as a vapor barrier.
Moreover, the cake of inversion flat roofs can be very different. It all depends on what you are going to arrange on the roof: a terrace, a mini-pool (and this is not uncommon) or a garden. But the foundation will still be common: a monolithic screed is made that levels the entire surface, then waterproofing is laid and all this is covered with insulation. And on top already - a cement-sand mixture or a rubber coating.
Note that the active operation of the roof is frequent damage to the insulating layer, due to which moisture makes its way to the insulation and freezes in winter. Over time, the entire roofing cake deteriorates, and therefore a flat roof cannot do without a ventilation system.
Cement-sand screed is able to even better distribute the pressure layer on the heat insulator, but it must be additionally reinforced with a mesh to prevent cracking.
The subtleties of flat roof insulation
A layer of thermal insulation for a flat roof is required. For comparison: gable roof they are insulated only when a residential attic is equipped under it, and in all other cases a maximum is laid mineral wool to the floor of the attic. But for a flat roof, insulation is always necessary.
The fact is that without a heat-insulating layer in a flat roof, condensate will constantly appear on the ceiling in the house (such a roof will just turn out to be the cold part on which water vapor rushes). And this is bad not only because it will have to be repaired, but also because the whole structure deteriorates in this way.
You can insulate a flat roof both from the outside and from the inside - the difference is small. More importantly, in how many layers a particular roof needs to be insulated - in one or two.
Thermal insulation materials must be attached to the base of the roof mechanically, as screws or dowels, and adhesive. Sometimes the mount is not used at all if the heat insulator is from the outside, and presses on it paving slabs or pebble.
Why two layers? The fact is that the first layer of thermal insulation on a flat roof performs the function of a heater, it is from 70 to 200 mm thick. And the second, from 40 to 50 mm, is designed to distribute all the loads. And it is important to calculate the thickness of both layers accurately, based on the climatic features of the area and the future use of the roof itself.
With two-layer insulation, all joints should go apart, in a checkerboard pattern, so as not to fall on each other. Moreover, in the places where the plates adjoin the walls and the parapet, it is additionally necessary to make heat-insulating bumpers. The cement-sand screed is able to distribute the pressure layer on the heat insulator even better, but it must be additionally reinforced with a cracking mesh.
Proper drainage system
But this is already a difficult task. Flat roofs are just bad because they are completely open to rain. But everything is solved! The main thing is to properly organize the drain, and for convenience, we have revealed this issue for you in such schematic illustrations:
Internal ventilation device
Another important point when arranging flat roofs - ventilation. The fact is that if moisture randomly enters the insulation, it no longer evaporates - it only accumulates. As a result, the heat-insulating material rots, and the waterproofing swells. And there are many reasons for leaks: broken waterproofing, mechanical damage to the top layer of the roof, cracks and damage from frozen water.
A damp heat insulator is also bad because of it bubbles and cracks appear on a flat roof in the summer heat - all due to the active evaporation of water. As a result, the roof covering is also destroyed. And if moisture eventually gets under the old screed, then the entire roof begins to flake off. That is why a flat roof must "breathe".
For this purpose, so-called aerators are used on it. They look like simple plastic metal pipes covered with umbrella caps. They should be placed evenly over the entire area of the roof, preferably at its highest points. The essence of such a mechanism is that different pressures are created inside the roof and the air begins to create flows, along the way, taking with it all the excess moisture vapor.
In practice, it looks like this:
In addition, in any living space, water vapor rises up to the ceiling. Moreover, they often successfully overcome this barrier (the water molecule is quite small) and already get into the insulation, which is bad for him. That is why vapor barrier is required. And not the one that is usually used to insulate the attic, but dense, made of high-quality polypropylene or polyethylene. The bituminous membrane is even more reliable.
Choosing the right roofing
So, what is used as a coating for such roofs?
Option #1 - bitumen and polymer-bitumen materials
Such roofs cost the owners of private houses the cheapest. Basically, we are talking about roofing material and euroroofing material. These are rolled roofing sheets, which are based on synthetic fabric, and on the sides are bitumen. As an elastic and frost-resistant material, bitumen serves as an excellent protection and waterproofing.
Moreover, the installation of bituminous roofing on a flat roof is absolutely simple, you only need gas-burner. The rolls are easily fused together.
But such a roof has a significant drawback - fragility. And also the fact that the roofing material does not breathe at all, i.e. vapor-tight, and therefore it is necessary to arrange ventilation for such a roof, unless you want the insulation to rot in a year:
Option #2 - liquid rubber
Such roofs have a huge advantage in that they do not contain any seams. As we have already said, the disadvantage of a flat roof is, first of all, that snow accumulates on it, which then causes leaks.
But there are subtleties here. So, liquid rubber for a flat roof, you need to take only two-component, preferably the highest quality. And it is extremely important to correctly apply this material on a flat roof: evenly, avoiding unnecessary layers and savings in certain places. So, where the paint was applied unevenly, problems should be expected after 8-10 years.
Option #3 - PVC, TPO and EPDM membranes
Roofing membranes are valuable as flat roof coverings in that they allow steam to escape. After all, no matter what the vapor barrier used, moisture still at least a little, but gets into the insulation, not only from below, but also from above - after heavy rains, for example.
There are three types of membranes for the installation of such a roof: TPO, PVC and EPDM. The most popular is PVC membrane, it is also the most combustible. The EPDM membrane is more durable and affordable, but if mechanical damage, it will be impossible to fix it with anything, while it is enough to melt the PVC membrane with a hairdryer. In addition, the joints of the EPDM membrane must be glued special tape, which is much less reliable than the adhesion of PVC sheets.
But the cheapest membrane in its sector is PVC. But it has such significant disadvantages as low resistance to ultraviolet rays and fear of contact with bitumen, various oils and even polystyrene foam, otherwise the service life is significantly reduced.
Bonding EPDM membranes requires professional skills. TPO membrane, like PVC, is also hot air weldable. It is not afraid of the best ultraviolet, it is more chemically resistant and can be laid directly on polystyrene foam or old bituminous roofing without geotextiles. But its service life is shorter than that of EPDM, therefore, for the installation of a flat roof of a residential private house, we recommend using a PVC membrane.
So, the pie of a flat roof device with a PVC membrane is traditionally made like this:
- Step 1. We arrange a monolithic floor slab.
- Step 2. We put a tear-resistant vapor barrier film.
- Step 3. We make a ramp out of insulation or screed.
- Step 4. We put a heater. In private construction, this is usually foam with 35 density, and on top - XPS with 50 mm, which is even stronger.
- Step 5. Now geotextile, 300-500 g each square meter.
- Step 6. We turn to waterproofing - this is the PVC membrane. The density of the insulation is sufficient to walk on such a roof. But, if you plan to make an open terrace on the roof, then the cake needs to be continued further.
- Step 7. Lay the geotextile again - now directly on the membrane.
We put rubber tiles or a reinforced screed 5-7 cm, on which we already lay paving slabs. To make a screed, you need ballast.
And such roofs are made of rubber, polymers or even foil. Unlike bituminous, they are durable, fire resistant and hold firmly to the base. They reach a slight slope with the help of expanded clay concrete or concrete screed.
How to achieve 100% waterproofing?
The main task when installing a flat roof is to make all joints and junctions as airtight as possible. After all, such a roof is most affected by moisture, hail, temperature changes and wind-blown debris. Therefore, the sealants used for sealing such joints must be of high quality and resistant to any influences. This is also a kind of expense that you have to go to.
For the same purpose of waterproofing, the slope of a flat roof is recommended to be at least 2%. Few? In fact, this is quite enough so that all atmospheric moisture does not linger on the surface, but flows down into funnels and pipes, and from them already into a septic tank, soil or sewer. Therefore, even at the design stage, you need to accurately think over the future drainage system.
Moreover, the drainage system itself is made both internal and external. So, internal drainage is a fitting - funnels located throughout the roof, which receive flowing water and direct it into pipes that go through buildings, but are isolated from living quarters. The only disadvantage of such a system is that the pipes are clogged with small debris and leaves, for which it is desirable to provide them with special filters and clean them periodically.
External drainage systems are already attached to the outer walls of the building. Of course, it is easier to clean such ones when they are clogged, but in cold weather they often freeze over. For which it is additionally customary to supply them with electrical heating in the form of cables.
As for the material for the inside and outside drainage system flat roof, then PVC or metal is quite suitable. Both options have their pros and cons. So, PVC does not corrode, but is more brittle than metal.
In order for the gutters not to freeze in winter, equip them with roofing thermal cables.
Green area on the roof: fashionable and environmentally friendly
Greenery and recreation areas are often not enough not only for the inhabitants of the "stone jungle", but even for the owners of private houses. The thing is that the same beautiful garden furniture it is not always possible to leave in the courtyard of the house, and beautiful rare flowers in the garden flower bed are often trampled by pets. Therefore, it is not surprising that the green area on the roof has become fashionable among the owners of cottages. Especially if the access to it goes immediately from the bedroom and no one else can disturb your morning peace with a cup of coffee.
There was also a fashion for some cafes to make the roof flat, and put on it small greenhouse. All the greens - immediately on the table! And it’s profitable, because it’s not so easy to bring fresh dill or onions to the kitchen, and it’s economically profitable - there is where to send kitchen waste. And it is difficult to understand who borrowed this idea from whom: enterprising residents of private houses with a flat roof, or the best minds Catering. But what is location closed ground profitable - this is a fact: rodents will not dig under the beds, insects and pests will not get (as well as pests in the form of neighbors), and the fact that it is always a little hotter on the roof is only a plus for the same tomatoes. But the main thing is to correctly calculate the loads on such a roof during construction!
And the roofing pie often goes standard: waterproofing on the floor, thermal insulation, geotextiles, drainage and again geotextiles. And on top it is already possible both the earth and the beds:
Or in this version for more powerful overlaps:
A flat roof is a huge scope for any fantasy. Designers and architects love to bring to life a variety of projects for her: a garden, a greenhouse, and treadmill, and a mini beach with sun loungers, and much more. Some craftsmen even manage to make a parking lot on it!
A flat roof is used today in the construction of a modern house. Most often, this option is chosen by wealthy people who always keep up with the times. Exists a large number of original projects of houses with a flat roof, which are multifunctional and comfortable for living.

Pros and cons of flat roofs
The following advantages are characteristic of a flat roof structure:
- It has a smaller area than pitched, thanks to which it is possible to save on material and construction work.
- It is much easier and faster to build a flat roof, which cannot be said about a pitched roof. This is due to the fact that all the materials for the construction are right next to the worker.
- The use of a flat roof allows you to get an auxiliary usable area that can be used for outdoor recreation and sports.
There is a flat roof structure and a number of disadvantages:
- due to heavy snowfalls, a lot of snow is concentrated on such a roof, which, when melted, leads to leaks;
- sometimes it is necessary to use internal drains; there is a risk of clogging or freezing of the drain;
- snow removal is required.
On the video - the pros and cons of flat roofs:
Here you will find houses of various sizes, number of storeys, basic construction material and exterior finish, which will undoubtedly become an adornment of your site. We can proudly say that we offer best projects houses with a flat roof!
Individual projects of cottages with a flat roof
If you did not find in the catalog a project of a cottage with a flat roof that satisfies your needs, we will be happy to design it for you from scratch. This is a very interesting, exciting and painstaking process in which you will plunge headlong. With your own eyes you will see all stages of design, from the general concept to the finished finished image, thought out to the details. Here we will take into account all your dreams, wishes and features of the landscape.
Features of projects of houses and cottages with a flat roof
Various architectural techniques entail the use of certain technical solutions. When creating projects for houses and cottages with a flat roof, the following important points must be taken into account:
1. In what climatic zone is the projected object located. This will affect the determination of the thickness of the insulation, or perhaps its complete absence. The rain intensity values will determine the height of the parapet and the number of sinkholes.
2. The roof can be with or without extension. Depending on this, the method of water disposal is determined. It can be external or internal, adjustable or unregulated.
3. It is necessary to determine the functional purpose of the terraces: will they be intended for the movement of people or cars, or will an additional soil layer be needed here for planting plants. The nature of the use of the terrace will directly affect the choice of the type of roof. There are traditional roofs, where the waterproofing is above the thermal insulation, and inversion roofs with the reverse arrangement of layers. If the roof is in operation, then to the hydro and thermal insulation materials there are still additional requirements for the perception of the load from people, cars or other vehicles.
Flat roof cottages are a way to stand out!
Unfortunately, the average resident of Russia does not yet associate his a private house with new modern architecture. Moreover, many believe that a flat roof is not suitable for our climate, or it is very difficult and expensive to maintain it in the future. These are all myths, of course! A cottage with a flat roof in our country is real. For some reason, everyone forgets that most apartment buildings built with a flat roof. If you follow all the technology for its construction, then there will never be any problems during operation.
Everyone has a natural desire to stand out, to be different from the gray mass. This applies to the choice of clothes, car and, of course, your own home. A well-designed cottage with a flat roof will certainly show your impeccable taste, especially since this is still a rarity in domestic private development. The architectural bureau of Ilya Eliseev is happy to help you realize, perhaps, the most important project of your life!
How quickly time flies! It has been 4 years since I built an unusual Vacation home. The house used a lot of non-standard technical solutions that were previously practically not used in individual construction in Russia. Firstly, the house is heated with help, 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 (but for what?), that it will definitely leak (why?), and in general, with such a roof, the house looks like a transformer box (poor Europeans, they have to live in transformer boxes).
But most often they tried to prove to me that it is necessary to constantly remove snow from a flat roof (I wonder why?). Of course, if anyone wants to, you can clean it up, no one forbids it. But on flat-roofed houses, there is no need to remove the snow. For example, now I have more than 80 centimeters of snow on my roof! And hid somewhere under the snow.
2. Snow on the roof is an additional and completely free insulation.
By the way, as it turned out, many do not know that a flat roof is not a plane in the direct sense, but a surface with a slope of about 2-4 degrees (in fact, a roof is considered flat if its angle of inclination is from 2 to 20 degrees). And on any flat roof, there is a drain. It is more correct for a flat roof to make an internal drain, 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 the internal drain in 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 one). With it, there is no loss of space and such a useless place in the house as an attic. It is easier and easier to insulate - everything is in the same plane.
Let me remind you the design of the pie of my roof (from bottom to top):
1. Prefabricated monolithic floor with filling aerated concrete blocks- 250 mm;
2. Insulation with extruded polystyrene foam - 150 mm;
3. Warming and creating a slope with the help of wedge-shaped plates of extruded polystyrene foam - 0-150 mm;
4. Cement screed - 50 mm;
5. Two-layer built-up waterproofing ( upper layer with sprinkles).
4. Another huge plus of a flat roof is that it is not afraid of a hurricane. Look at the hurricane chronicles and how easily the coating is torn off and broken truss system on classic pitched roofs.
5. In the summer of 2016, I completed all other landscaping work on the adjacent territory and decided to do it.
6. By the way, if anyone does not know, then any concrete floor by default, it has a bearing capacity of at least 400 kg per square meter (typically 600-800 kg/m2). While snow load for the Moscow region is only 180 kg per square meter. This is the maximum design snow load, which in reality is rarely achieved, but it is obvious that any overlap has a huge margin in terms of bearing capacity.
7. One more thing important advantage flat roof in that it has completely sealed seams. While on a pitched roof, the seams are not tight and if the pitched roof is covered with snow and it starts to melt from below (due to insufficient insulation), the pitched roof will leak (especially at the junction of two slopes - valleys). Look at the neighboring houses pitched roofs Surprisingly, they also have snow on them!
Why does a flat roof made according to technology not leak? Everything is very simple. Because it's 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 entire building. If the roof is not insulated, or not well insulated, then the heat will rise up, and the snow lying on the upper roofing carpet will melt. When frost sets in, the melted snow will freeze again, and when it freezes, as you know, water expands in volume. These multiple freeze-thaw cycles will eventually rupture 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, therefore, roof insulation was usually not done. This led to the fact that the waterproofing of the roof was constantly destroyed and the roof was leaking.
If the roof is qualitatively insulated, then it has only one "enemy" - the sun and its ultraviolet radiation. But to protect against this, waterproofing is used with a package, or with special additives (if used). And the most effective method protect waterproofing from damaging ultraviolet radiation - make a lawn on the roof, fill in pebbles or lay tiles. By the way, a more promising waterproofing today is a polymer membrane.
A flat roof is even easier to operate than a pitched one. With a flat roof, snow will never fall on your head and gutters will not tear off. Snow does not need to be cleared, and if there is a lawn, there is no need to monitor the cleanliness of the gutters (all water is filtered through geotextiles and they will not clog with fallen leaves).
Therefore, a flat roof is the most reasonable roofing option, especially for a house from. The main thing is not to break the technology and not save on insulation.
And cleaning snow from a flat roof is not only useless, but also harmful - you can accidentally break the waterproofing with the sharp edge of a shovel and the roof will start to leak.
