Cottage with a flat roof. One-story house with a flat roof - advantages and features of installation

Projects of houses with flat roof have become more popular all over the world lately. Some instances of houses can be safely called masterpieces of architecture. In our country, this direction is still developing, therefore, choosing such a solution for construction, you become the owner of an exclusive modern home.

Flat-roofed houses look spectacular, and are also endowed with a number of advantages:

• roof construction will take less time and cost less;
• ease of maintenance, cleaning and repair work is carried out easier and without the use of special equipment;
• the possibility of useful use of the roof area, for example, to arrange a terrace, tables for relaxation, a flower garden or a sports place.

Construction of houses with a flat roof

Despite its apparent simplicity, the strength of the house will be achieved only with careful carrying out of the necessary calculations, especially when it comes to ensuring a sufficient level of waterproofing and water drainage, in case of an error, the structure may collapse. That is why for the design and construction of houses with a flat roof, it is necessary to contact specialists who have sufficient experience and comply with the required building codes and standards.

Our catalog contains many finished projects houses with a flat roof. Using a convenient filter, you will find various houses by area, number of floors and material of execution (brick, aerated concrete, frame) with a photo and price for construction.

If no cottage project fits in the catalog, we will gladly develop individual project for you, where we will take into account and implement all your wishes.

Cooperating with Villaexpert, you can be sure that the construction of a turnkey flat roof house will be carried out at the highest level and at a reasonable price, and you will receive a house project as a gift.

Today, people are increasingly choosing flat-roof house options for their country cottages, positively evaluating a number of obvious advantages associated with such a design. Among these, the main and most attractive advantage and the ability to actively exploit this roof. A small swimming pool, a greenhouse or a small garden are placed on the surface, you can put external units of a split system, or just relax after a working day in a comfortable sun lounger. In this case, it all depends on the imagination of the owner of the house. In the article we will consider in detail the projects of such houses, we will talk about their advantages and disadvantages.

Design features of a flat roof house

Flat roof options take up a much smaller area when compared to various pitched roofs. In addition, the choice for flat version useful due to significant savings. Moreover, a flat roof is made much faster, construction time is significantly reduced.

Your roof will not be completely flat, as such a design always has a small slope, which is three to five degrees, it goes to the middle of the house.

Due to the bias in rainy weather water will flow into the gutters, it is better to make them heated so that they do not freeze in winter. In addition to such a drain inside the house, as a rule, several external drains are additionally constructed.

Opponents of flat roofs argue that due to the characteristic construction, the roof will be subject to heavy loads, such as in winter when there is a lot of snow. However, there are much more advantages here, besides, if the house is warm enough, then in winter the snow will constantly melt, and drains will come into effect.

Important! Today, a large number of resistant, therefore, reliable materials are produced, which provide not only architects, but also builders with a wide range of options.

Taking into account the design of the roof and the individual characteristics of the house, roofing materials are chosen, they can be very different. For example, bitumen-polymer mixtures are often used, among them there are hundreds of different types.

Elastic and rather light EPDM membranes, as well as polymeric TPOs, are also very popular. Also today it is possible to purchase a ready-made reliable system for arranging a building with a flat roof.

The choice of the right coating depends not only on the design features of the house, but also on its location.

Houses with flat roofs: options (photo)

A flat roof is different, depending on how it will be used, and hence there are designs in two different directions: for further operation and without it.

Since both solutions have not only positive aspects, but also negative points, it is important to carefully weigh all the arguments before ordering a flat roof house project.

In any case, you should not save on the roof when building a house, since this is not only the protection of the structure from all large and small natural disasters, but also an aesthetic component that is noticeable to prying eyes.

Exploited flat roofs

Such roofs allow households to use the entire space of the roof above, but when constructing it, a number of important nuances. First, a hard type base is prepared. It could be either concrete screed, or profiled sheet patch.

If the roof will be constantly used in the house, it must be adapted for the comfortable movement of people on the roof covering. In addition, it must be taken into account that due to the constant pressure that arises from people walking on the roof, the roof can leak over time. For this reason, you need to take care, as already mentioned above, of good protection from moisture and rain.

The most elementary option for arranging a recreation area on the roof for the whole family is a breakdown of an ordinary lawn. For a cozy arrangement of a flat roof, some kind of combined coating is often also used. It could be a deck board harmonious combination with neat . This option is more acceptable if the family plans to occasionally hold picnics on the roof in nature under the stars.

Lightweight type can be put on the roof garden furniture, which will be here permanently. In addition, it is good to build a special glass ceiling directly into the ceiling so that it illuminates the lower floor.

In order to protect against gusts of wind, as well as unwanted prying eyes, special wooden screens are installed directly on the roof surface, they can also play an aesthetic role. Even more comfort will give small ornamental plants in small tubs, which winter time years are removed from the roof.

Very often a small pool is installed on the roof. If the weight allows, and the foundation and the wall structure itself are quite strong, you can even build a mini-beach on the roof.

In order to make it easier for you to endure the heat, small canopies are installed near the pool, which will create a dense shade. You can also put plants with large and spreading leaves nearby.

Unexploited flat roofs

If there is no desire to exploit the roof, then the worries when building a house for the construction of a foundation with increased rigidity go away, and besides, you do not need to carefully select the best and most reliable heat-insulating materials.

For periodic Maintenance such a roof in several places small bridges are equipped. The cost of the structure will be much lower, but its service life is somewhat less.

Unexploited structures may well be effectively applied in solving various technical problems. This is, for example, the installation of a satellite dish, a mini-observatory.

Many home owners install solar panels on the roof, which is very advisable. The weight of such batteries is, in principle, small, so that with the correct arrangement of the equipment, the roof will not suffer at all.

Important! Rooftop solar panels will not only help the family cut down on electricity bills, but they will add another element if, which is logical given the boxy shape of the house.

Experts still distinguish the so-called inversion option for building a house with a flat roof. Sometimes such a modification makes it possible to create a certain style of the whole structure, taking into account the creative thought that the designer is trying to bring to life.

When creating such a roof, waterproofing is applied to a waterproofing carpet. This helps to protect not only from moisture, but also from negative impact a sharp temperature drop, from the hot sun, especially if the house is built in an open area and in the midday heat it is exposed to an active “attack” of direct sunlight.

On a note! Such a device would significantly increase total time operation. On the equipped roof, you can put or mount a real greenhouse.

Beautiful projects of houses with flat roofs (photo)

A suburban modern house with a flat roof is a compact one-story or two-story cottage, as a rule, it has a lot of glass and is geometric in shape.

An experienced architect can create a non-standard and very beautiful, which will be built of metal, wood and concrete, created on the basis of emphatically strict rectangular or dynamic diamond-shaped shapes.

On a note! Very often, houses with flat roofs are decorated with facade chimneys, which are laid out with wild stone, this brings a peculiar zest to the building and makes it cozy.

Now you can consider more original and beautiful options houses with flat roofs. Recently, due to the fact that such styles as hi-tech, pronounced and especially constructivism, which are generally unthinkable without a flat roof, have become very fashionable, such a laconic design is becoming more and more dense in our everyday life.

Flat roof house in the style of constructivism

The idea to make full use of the unused space on the roof came from Le Corbusier, who is considered the pioneer of functional architecture. People have always wanted to put sun loungers, pools and gardens on rooftops, but previously there were no such high-quality waterproofing materials as there are now, so flat roofs just leaked. Today, this problem has been successfully solved, which is why constructivism has been reborn from the ashes, and is so fashionable today.

It is worth mentioning the top options. For example, this is the decoration of the facades in a house built in the style of classical constructivism, in black tones. At the moment, this is the real trend in the field of architecture, and it is becoming more and more popular.

The dark shades of the walls will give the building a stylish and trendy look. Today in constructivism metal parts structures, glass, as well as non-plastered concrete are adjacent to the façade cladding made of exotic wood.

In the generally accepted architecture of constructivism, any complex curvilinear volumes and shapes are completely absent, there is only a straight line, as well as a circle. Completely devoid of the traditional basement, such houses "grow" directly from the ground. In combination with a flat roof, all of the above will look ultra-modern.

High-tech country houses with flat roofs

This style continues to be relevant, its fans prefer to fully adhere to the appropriate design both in the design of the premises both inside and outside.

The characteristic features of a house with a flat roof in a high-tech style are a pronounced technogenicity, the smoothness of all surfaces, and a specific textured finish.

This style is always focused on the emphasized demonstration of various techniques, for this reason, simulators, appliances installed on the roof can be adjacent to sun loungers and green spaces, and it will be harmonious and fit into the overall style.

• A characteristic feature of the high-tech direction is a large amount of light. On the roof, you can install small flashlights and several large main light sources. Around the perimeter of the house will look stylish.

Private house with a flat roof in the style of minimalism

This is a style in which flat roof houses are one of the attributes of the whole direction. The functionality of minimalism is fully consistent with the geometric shape of the house with a flat roof.

Floral arrangements, as well as decorative cereals that can be used to decorate the space on the roof, will soften the excessive severity of your home.

It should be mentioned that if the shape of your house is devoid of any protruding architectural excesses: for example, balconies, any, and especially ledges and bay windows, then you will get rid of many problems. Firstly, such a structure will cost much less than an ordinary house under a traditional one for our regions, and secondly, it is easier to equip a simple type of roof.

Minimalist house- does not claim to have a special beauty associated with courage architectural forms, but on the other hand, the pragmatic goals of the household will be resolved very effectively.

In order for the restrained and laconic architecture to acquire a certain expressiveness, contrasting or bright colors can be used for facade decoration. color schemes, use ultra-modern Decoration Materials, not only natural, but also synthetic.

Different color combinations of finishes, as well as original and non-standard combinations of various textures, will give color to your home, the facade can be plastered, it can be sheathed with plastic. perfect brick facade, reliable and very solid.

Houses with flat roofs, photos of which are full on the Internet, are becoming more and more popular. And this is not surprising. After all, what could be more pleasant than relaxing on the roof with a cup of fragrant tea, talking with friends, exhaling the aroma of plants from a small greenhouse, starry sky and fresh air.

The flat-roofed geometric house is a classic example of the beauty of 21st century architecture, which is revealed through the rigor of forms in the frame. beautiful finishes and well-chosen accessories.

”was perceived extremely negatively - the legacy of Soviet construction affected, when, due to a violation of technology, poor quality materials and performance of work, flat roofs of high-rise buildings began to leak after a couple of years.

Therefore, in private housing construction, preference was given to pitched or hipped roofs. The situation changed with the advent modern technologies and roofing materials, which made it possible to provide durable and reliable waterproofing of the roof of a house with a flat roof.

Flat roofs: advantages and disadvantages

The main reason for the growth in the popularity of a flat roof was the popularity of modern design trends - project high-tech houses with a flat roof allows you to match the exterior and interior of the building with style features. Another flat roof is often used in modern and minimalism.

However, in addition to a spectacular look and visual appeal, it has a number of other advantages:

• speed of roof construction - arrangement flat roof takes less time than a pitched (hip) roof, including due to the convenience of working on a horizontal surface

• availability of maintenance - there is no need to install ladders or involve steeplejacks, all work (cleaning drains, controlling ventilation ducts, cleaning leaves, etc.) can be done independently

• obtaining additional space due to the arrangement of an exploited roof

• flat roof is ideal for installation and further operation/maintenance of various technological equipment – solar panels, wind turbines, heaters, air conditioners, antennas, water collection systems.

A rather controversial issue is the cost of installing a flat roof. On the one hand, the area of ​​\u200b\u200bsuch a roof is much smaller than that of a pitched one, which means that less roofing materials will be required. And the roofing materials themselves used for flat roofs are cheaper.

But, on the other hand, the use of reinforced concrete floors (in most cases, especially when creating an exploitable roof) creates a significant load that requires strengthening the foundation and load-bearing walls, especially if these are projects two-storey houses with a flat roof. Which, while saving money on a roof device, leads to an overall increase in construction estimates.

The issue of snow accumulating during the winter on a flat roof remains ambiguous. Some experts tend to consider this a positive moment - snow acts as an additional layer of heat insulator, thereby reducing heat loss. Others argue that snow increases the load on the load-bearing elements (and, therefore, this should be provided for in the project), and its subsequent melting can provoke a violation of the tightness and leakage of the roof.

Types of flat roof

Projects of houses and cottages with a flat roof can have different kinds roofs:

• exploited - provides for the regular presence of people on the roof or the installation of heavy objects. Such a roof requires a rigid base (most often reinforced concrete), and the heat-insulating material must withstand serious static and dynamic loads, be strong in compression

• non-exploited - does not provide for a large load, so a rigid (concrete) base can be replaced with wooden logs with a crate. To maintain such roofs, special ladders or bridges are used to reduce pressure and evenly distribute it over the entire roof area.

• inversion - the insulation layer is located above the waterproofing layer, thereby providing it additional protection from temperature extremes, ultraviolet radiation and mechanical influences, the number of freeze / thaw cycles increases. Together, this leads to a significant increase in the life of the roof. Most often, inversion roofs are used as operated ones - you can put furniture on such a roof, walk or break flower beds.

Operated roof: every square centimeter is in action

The ever-increasing cost of modern housing is forcing the most efficient use of all available space, and this will help projects of houses with a flat exploited roof. In fact, if we consider projects one-story houses with a flat roof, the owners have at their disposal an additional "seasonal" floor, which makes it possible, for example, to refuse verandas, thereby freeing up additional area on the site.

Decorative flat roof garden

The domestic consumer has long been familiar with the features of a flat roof, and believes that it is used for multi-storey government buildings. But modern manufacturers decided to expand their market, and found a new application for it.

It is surprising, but appeared with a flat roof, featuring the same set of functional features. It is suitable primarily for the area in the territory in which snowy winters and strong winds occur at the time accompanying their manifestation.

Their power will quickly blow away large layers of snow, and the roof will always be clean. And powerful hurricanes will not be afraid of such a roof covering. The thing is, it doesn't actually exist.

But this is only part of its capabilities. It will be possible to place many useful buildings for different seasons on it. This may be a greenhouse or a small garden, or maybe a dance floor. Other options are available, based on the strength of the imagination of its owner.

But in order for everything to work out well, it is necessary to study the nuances of creating such structures. Now let's take a look at many issues related to this topic. To begin with, we advise you to familiarize yourself with the photo of houses with a flat roof, which have already proven their suitability for various purposes.

What is the benefit of this roof structure?

If we talk only about a private house, then they lie in the following points:

This version of the roof will take up a smaller area in comparison with the most gently sloping pitched modifications. This will help save on the amount of materials.

The process of its construction is noticeably faster than the installation of a gable or hip version. Due to this feature, it is much more profitable to create modern houses with a flat roof.

Comfort and safety of the necessary rafter work processes are ensured. It is quite spacious and difficult to fall off.

It differs from the gable design in that there is no need to carry out dismantling work from the outdated coating. It can be used as additional waterproofing or protection. This will help save energy and time.

Its surface is suitable for use as an additional territory for organizing a flower garden, a cozy terrace, a greenhouse.

Various transparent elements can be mounted to help organize beautiful view on the open starry sky at night or clouds with the sun in the daytime. And a charming view opens up to admire the rain or a strong storm - there are fans of this state of nature.

Helps to adjust the house to the basics of the minimalist style. It has now gained notable popularity.

What are the disadvantages? “Unfortunately they are…

If there is no strong wind, this option generously collects a lot of snow on its surface. You will need to clean it often in order to use the territory for your own purposes. Sometimes it can lead to noticeable leaks.

Clearing snow will often have to be done by mechanical means. They can damage the roof.

The structure of the roof is particularly complex in comparison with other types of forms. It will have to organize a lot of drains. They, in turn, often get clogged.

From the pitched version of the roof covering, water flows off on its own and this happens very quickly. She doesn't do much damage.

On the flat version, the water usually stands still and builds up as the rainfall lasts. You will have to control the humidity of the insulation and make the coating at a small angle so that the water gradually finds the drains.

It will require less materials than for pitched. But the creation itself is much more complicated. There are many subtleties that not everyone knows about, and therefore often this version of the roof does not turn out the way it was intended.

Because of this, many believe that a flat roof in a private house is not the best way. But now domestic manufacturers have learned about the positive Western experience and have learned how to create the right materials.

And installation specialists have adopted methods quality work in this direction, and the situation began to change for the better. This approach has already taken root in Russia.

Is it suitable for frame versions of houses?

Yes, today you can see a frame house with a flat roof, more and more often it is perceived as commonplace. This roof can be two directions. For operation and without it.

If the roof is to be used, then it will be adapted for the convenient movement of people on its surface. For this, a rigid version of the screed or another version of the rigid base is used. Due to the pressure from the movement of people, the roof can leak. In this regard, it is necessary to consider the creation of reliable isolation from water.

But there is a version without human exploitation. Usually no one walks on it or rarely appears to clean its surface. The load on its area is distributed over the entire surface. But she has one major problem. Its service life is too short. Although such a version, due to possible, situation-satisfactory features, is often used.

There is also a classic version of a flat roof. It is often referred to as a soft roof option. It is formed by a carrier plate. Thermal insulation on it is laid on top of the coating for vapor barrier. And then a bituminous version of the waterproofing in the form of rolls is rolled over the thermal insulation.

Due to the advantageous features, this option is used to form such a modification of the roof on frame house more often than any other.

But experts also distinguish an inversion version for the formation of a flat roof. Sometimes this modification helps create the style of a flat roof house with the creative mind of an experienced designer. It is distinguished by the fact that the waterproofing will have to be applied to the waterproofing carpet.

This will help protect against temperature changes and ultraviolet rays from the sun, which is important if it is located in an open area and under their direct access. And this version also allows you to increase the service life - the force of impact on the waterproofing from the processes of melting or freezing of snow precipitation is noticeably reduced. It is quite suitable for installing furniture, mounting a greenhouse.

Important Points

For a high-quality arrangement of a flat version of the roof, in any case, laying the correct version of the carpet will be required. It will help soften the base in case of thermal or mechanical stress. This will help ensure the durability of the coating.

Now, based on the influence of Western culture, Russians have begun to pay more and more attention to this roof option. The domestic user realized that a cup of coffee at any time on such a roof is a wonderful option. Here open sky Anytime. And there is constant access to clean air. This is great option, and here pitched roof cannot offer it.

Of course, not everyone can afford such a roof. Usually the maximum for a Russian is access to a balcony. But over time, it will become a reality for every inhabitant of our country.

If you have the opportunity to create it today, there is no doubt that this is the best option. Today, high-tech style houses are gaining great popularity and, on their basis, a flat roof is mainly used. She has become their full-fledged companion.

Photo of houses with a flat roof

Not everyone likes modern construction. This is immediately clear when flat roof house designs are mentioned in a conversation. Most builders don't like it. appearance, but after living in such a structure for a while, their view changes. It is due to its minimalism that this house is considered stylish, but the vast majority of Russians are accustomed to pitched roofs, they just can't imagine a roof without a slope. In this article I will try to reveal in as much detail as possible the beauty of a house with a flat roof.

One-story house with a flat roof

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

Flat roof houses and their projects are presented in these photos:

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

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

Pros and cons of a flat roof house

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

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

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

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

• Large heat loss. Due to the simply huge plane, serious heat losses occur. This can be corrected by laying thick insulation in several layers. In the process of routine inspections, this material should be given the most time so that the underlying premises always remain warm.
• Without laying the insulation cord, the internal drain can freeze during severe frosts.

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

Modern flat roof houses are built according to crazy projects, if you contact a good architect, you can end up with buildings such as these photos show:

Types of flat roof

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

• Make her exploitable
• Make her unexploitable

Before starting construction, at the time of design, it is very important to decide on this issue. After all, if the roof is exploited, then the installation of massive elements will be required, which will easily withstand serious weights. In cases where an unexploited surface is installed, the entire building can be framed. By the way, wooden frame houses are very relevant in America and in the warm countries of Europe. As for Russia, it is better to use thick walls here, otherwise it will not be sweet in winter.

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

Unused roofs cannot be used as a recreation area. Often, flooded roofs are laid on such surfaces, therefore, you can move along them exclusively by bridges or ladders. Such materials allow you to save money, but at the same time they have maximum waterproofing performance, so you can fill the pool on such a roof, but of course you should not do this.

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

• Traditional
• inversion
• breathable

Traditional roofing cake has the following structure:

• Base
• Screed
• Vapor barrier layer
• thermal insulation
• Waterproofing
• Finish coat

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

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

• Base
• Screed
• Waterproofing (as a rule, it is roofing material)
• Thermal insulation boards

• Vapor permeable film with high throughput
• Screed
• Finish coat

As you can see, there are two layers of screed here. This is done so that the heat-insulating plates do not deform under weight and always perform their functional tasks with high quality.

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

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

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

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

Flat roof base

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

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

Between floors, a heat-insulating and waterproofing layer is not laid on these elements, but upon completion of the last floor, this is mandatory.

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

As for the exploited surfaces, here the variety of roofing solutions rolls over. You can plant trees on the roof, cover the area with a lawn, put a gazebo and much more. But the most important thing is of course the roofing. It is very important to consider the nature of your plane here. For example, if you want to put a gazebo, then near it it would be nice to cover the area adjacent to it with grass or flowers, and make the approach from paving slabs. Projects of houses with a flat roof allow you to do more than that, the main thing is to understand what exactly you want.

Often on the roof of private houses you can find a pressure coating. They are gravel and soil. The load from such materials is very high, therefore it is suitable exclusively for exploited types of roofs. It is worth noting that their structure will be somewhat different from the inversion one, but you can already check this with some designer.

Reinforced concrete slabs with screed perfect solution if you are considering cottage projects in the catalog where budget options. If we lay these elements as a ceiling, you will get a sufficiently rigid base to create a good exploitable roof.

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

Lightweight materials are often laid on the roofs of frame houses. For example, polystyrene foam boards are used as thermal insulation products, and modern membranes are used instead of a heavy coating. Thanks to this, a very light and not expensive building is obtained, which can be used for any purpose.

Materials for roofing cake

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

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

• vapor barrier
• Thermal insulation boards
• Coating

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

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

• Styrofoam
• Rigid mineral wool
• Foam glass
• Expanded clay filler

IMPORTANT: Foam glass is very effective heat-insulating material but the price is quite high. If you are planning to build a quality building that will last for more than a decade, then it is worth choosing it.

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

As you already understood, the coating should also be light and in no way allow moisture to pass through. This list can include: jellied roofs, membranes and bituminous derivatives such as roofing material.

Gutter system

The gutter system on a flat roof deserves a separate topic, but I will try to explain everything in a nutshell.

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

• Create a system with overhead gutters
• Build an internal drain

It should be noted that both methods have their own positive aspects and shortcomings. For example, an external gutter system will spoil the appearance of a building with a flat roof. Of course, this problem can be solved with the help of design tricks, but this will have to spend additional finances. Concerning internal system, then here I want to talk more openly.

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

Internal drainage is divided into two types:

• gravity flow
• siphon

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

The siphon system is more complex and more efficient. She can deal with large quantity precipitation without experiencing any problems. The essence of her work is that she does not remove water from the pipes until a sufficient amount has been accumulated in them, and then, due to gravity, brings them into storm sewer. By the way, after the process of removing water in the pipes has begun, different pressures form from above and precipitation from the roof leaves through the pipe at an even greater speed. Due to this, such a system very rarely becomes clogged, therefore it does not require almost any attention. The disadvantages include its high cost and problematic device.
