Country house with a flat roof. Houses with a flat roof - selection of materials and technology for the implementation of roofing works (70 photos)

Flat roofs are used in both high-rise and low-rise urban buildings. They allow you to save on lumber, since their arrangement does not require a bulky truss system, and the installation of insulation and roofing is carried out on the floor slab of the upper floor. For drainage, a slope is created on a flat roof, along which excess moisture flows into the pipes of the internal drainage system. In suburban construction, flat roofs are also used, and an operating structure is mounted on some of them. We will tell you about the features of the layout of such houses, consider some options for their arrangement and operation.

Features of the layout of houses with a flat roof

For the climate middle lane at home with flat roof are not the most popular choice, but at the same time, an unusual design finds fans, and the ability to equip a recreation area on the roof makes projects of this kind attractive. Buildings with flat exploited roofs have their advantages and disadvantages and are used in areas with moderate snow formation and relatively mild climate. The advantages should include:

original appearance;
lack of complex and cumbersome truss system exposed to wind;
the possibility of using a flat roof as an exploited space;
the absence of an external drainage system on the facades of the building, since an internal drainage system is used instead.

Flat roofs also have some disadvantages, namely:

increased requirements for the strength of the floor, which must withstand the weight of snow;
the need to create a slope towards the drainage pipes, which means that there will be an increase in the mass of the roofing cake;
high quality requirements for multilayer waterproofing;
frequent preventive and overhaul repairs.

The design and construction of flat roofs is based on the standard SO 002–02495342–2005 “Roofs of buildings and structures. Design and construction”. This document outlines the principles of roofing pie design and methods for constructing flat roofs. When creating a project, it is necessary to take into account not only the presence of ventilation ducts, but also drainpipes through which moisture is removed from a flat roof.

A flat roof allows you to create a cozy living space with the same or different height ceilings for comfortable living

The standard SO 002–02495342–2005 pays attention to maintained and inverted roofs with earthen and grass coverings, as well as methods of waterproofing and additional strength testing of flat roofs according to SNiP 2.01.07. Additional ground layer with waterproofing, paths made of paving slabs and the presence of a fence require strengthening the floor structure, as well as the construction of a flight of stairs to access the roof. On flat roofs, it is necessary to make a slope of 2 to 5 degrees towards the downpipe to ensure the outflow of excess moisture.

The exploited roof implies a multilayer structure of the roofing carpet and a specific design of the funnel of the drainage system

A flat roof overlay is made in one of the following ways:

With standard reinforced concrete slabs.
The overlapping of a flat roof with standard reinforced concrete slabs is carried out with sealing of joints and installation of a reinforced belt
Continuous concreting of the armored belt and reinforced floor with support on internal partitions and external walls building.
Continuous concreting of a flat roof is carried out with support on the load-bearing external walls of the building
Reinforced concrete ceiling using corrugated board and supported by load-bearing steel beams.
Beams to create a flat roof overlap are attached to load-bearing walls, and corrugated board and reinforcement are laid on them, then concrete is poured

A solid ceiling makes it possible to place telecommunications equipment, ventilation and air conditioning systems on a flat roof, as well as to equip the operating space. For house planning flat roof affects the internal placement of the drainage system, chimneys heating system, flights of stairs, as well as the location of the garage. Roof ladders can also be mounted on the outside of the building, which significantly increases the living space.

Examples of flat roof house designs

Flat roof houses have been used in prefabricated urban construction for many years. With the advent of new waterproofing materials high strength, it is not difficult to equip such a structure on a building of any number of storeys, built from different materials. In suburban construction, it is quite difficult to break the stereotype of fear of snow load on a flat roof. It should be noted that reinforced concrete floor in strength exceeds any of the pitched roofs, the truss system of which is made of lumber.

Flat roofs are successfully used in both high-rise and low-rise buildings.

Buildings of this type have a finished appearance and concise design. Consider examples of flat roofs on houses of different heights built in different styles and from various materials.

One-story houses

One-story buildings are designed to accommodate a small family and the apparent small size does not interfere with placing the space necessary for a comfortable existence under a flat roof.

Single storey flat roof house suitable for a small family

A mine has been brought to the roof ventilation system and a chimney, and excess moisture is removed through a drainpipe on the facade, which does not spoil general form at home. The owner of such housing should keep in mind that over time the living space may have to be expanded, so certain areas should be reserved for this.

The design of the house with a flat roof allows you to expand the habitable space by adding a garage and a terrace.

two-storey houses

For two-story house the layout is typical, in which on the ground floor there is a garage, a hall, a living room and a kitchen space with a dining room. On the second floor, they equip an office, a recreation area with a large open loggia or terrace. The presence of cars in the family implies the equipment of driveways.

The two-story house with a flat roof allows you to accommodate all the necessary spaces.

In houses of this type, ventilation ducts, chimneys and a drainage system are combined into one block and located inside the building, and the garage room is equipped with a separate ventilation duct. Housing is designed for year-round use and has all the advantages of its own suburban building.

With the help of light coloring, a two-story concrete structure can be made weightless in appearance

Houses with an exploited roof

An exploited roof implies the use of a more durable ceiling of the upper floor, multi-layer waterproofing and a strong fence. On such roofs there are recreation areas with a solarium, lawn and other vegetation. In addition, in the operated part of the roof they place technical blocks with air conditioning, ventilation and telecommunications equipment.

The operated roof requires reinforced overlap and multi-layer waterproofing to effectively remove excess moisture.

On some part of the area, paving slabs are laid, furniture and light sheds are installed, so the total weight of the roof in use must be taken into account when constructing the ceiling. Subject to the installation technology and the use of high-quality materials, such a roof can last for many years in the climate of the middle lane.

Frame houses with a flat roof

Prefabricated frame houses must have a solid ceiling of the upper floor, which is carefully sealed, since the details of the frame, in case of moisture penetration, may be susceptible to decay.

The frame house is characterized by high construction speed and low material costs, but requires careful attention to the strength and waterproofing of the floor

When arranging a flat roof in houses of this type, one should carefully consider the coordination of the snow load with the strength of the building and the reliability of the ceiling of the second floor.

High-tech houses

Stylish, bright, flying structures, sparkling with glass and nickel-plated metal, strict concrete structures and wide staircases leave an unforgettable impression of high-tech houses. The building seems to hang without any support, has big windows, high ceilings and ample interior space.

Houses built in high-tech style are distinguished by an abundance of light, glass, metal and concrete.

A house built in this style is expensive and very time consuming to manufacture, since it is a monolithic concrete structure.

Houses from sip panels

Heat-insulating sip-panels are easily and quickly mounted in any weather with the help of vertical racks and have considerable strength. A house built from panels needs a solid floor with good waterproofing..

Houses with flat roofs made of modern sip panels are quickly built and have good thermal insulation.

From sip panels, you can quickly build reliable buildings of various configurations.

Wooden houses

A house built of logs or timber is durable, warm and environmentally friendly. Wooden houses can be brought under a flat roof with the condition that flame retardant and antiseptic impregnation of the structures of the last crown and the ceiling of the upper floor be carried out.

Drainage with a flat roof is made by pipes located both inside and outside the building.

A wooden house with a flat roof fits very organically into the surrounding space.

Houses from foam blocks

A budget version of a house made of foam blocks with a monolithic reinforced concrete frame. A reinforced concrete belt is built along the upper part of the walls of the second floor, and a flat roof overlap is laid on it and on the internal load-bearing walls.

Warm and economical houses from foam blocks are often completed with a flat roof, which is a logical continuation of the architectural style

Drainage systems, ventilation ducts and chimneys are mounted inside the building and are not displayed on the facade. The strength of such a house allows you to equip an exploited flat roof.

The concrete foundation and ceilings with the walls of the house can be built from warm foam concrete with a natural stone finish

Modular houses

These houses are assembled from a standard set of ready-made modules located in necessary order. Such buildings are equipped with flat roofs and have good heat-shielding properties.

Modular house- a building that is assembled from standard blocks-modules and connected into a single whole, depending on the functional purpose

Modules are created on the basis of ready-made functional elements and are designed into a single building with a suitable stylized finish.

Reinforced concrete panel houses with flat roofs

This type of houses includes all urban development and some types of low-rise suburban buildings. High degree standardization allows you to build houses using a set of panels and floor slabs, as well as build flat roofs using specialized blocks.

Panel houses have high strength and are prefabricated buildings of a standard type.

Reinforced concrete products have not only strength, but also high heat-insulating characteristics.

Standard reinforced concrete products allow you to mount a building of any complexity with a flat roof

Flat roofs in our time are undeservedly forgotten and are not spoiled by the attention of developers. In private housing construction, they are found mainly in the southern regions, where heavy rains and snowfalls are rare. Hip roofs, on the other hand, have become firmly established in the designs and minds of homeowners.

This state of affairs is explained simply: until recently, builders did not have reliable and durable waterproofing.

Standard roofing material - cardboard impregnated with bitumen, cannot resist moisture and temperature changes for a long time. Even a thick 4-layer coating of it has to be changed after 6-8 years.

Today, interest in flat roofs is starting to grow.

There are several reasons for this:

Economic benefit. The cost of arrangement is lower than that of a tented one (more simple design and smaller area)
Additional usable area. There is the possibility of its rational use (flower garden, playground, recreation area, swimming pool);
Availability for maintenance and operation (cleaning drains, installation of air conditioners, antennas, inspection of coatings, ventilation and smoke channels);
The layer of snow plays the role of additional thermal insulation, reducing heating costs.
The original appearance of the building.

Types of flat roofs

Strictly speaking, you will not see a completely flat roof on a building. Any of them has minimum slope from 1 to 4%, necessary for the runoff of atmospheric precipitation.

There are four types of flat roofs:

unexploited;
exploited;
green (lawn);
combined.

Unexploited roofs are found on industrial buildings.

Exploited roofs have found application in public and private construction. They equip recreation areas, place cafes and restaurants, use them as parking lots and helipads.

Green (lawn) coatings are made to decorate buildings, as well as when there is a shortage of space on the site. In addition to the aesthetic function, they perform an important practical task. A layer of vegetable turf is an excellent heat and sound insulator.

Combined roofs with a flat surface are the most common option. Comfortable stay on fresh air surrounded by green grass and flowering plants everyone likes it.

According to the method of drainage, houses with a flat roof are divided into two types:

With internal drain;
With external water discharge (along the perimeter of the roof).

Internal drainage is cheaper than external drainage, since it does not require a large number of gutters, pipes, funnels and high-altitude installation work. In execution it is more difficult. Errors in creating a slope, poor-quality sealing of joints lead to leaks and a violation of the integrity of the protective layer of waterproofing.

In operation, flat coatings with internal drainage are more profitable. In winter, icicles do not grow on the overhangs near such a roof. Downspouts pass inside the building and therefore do not freeze. Cleaning funnels from debris is easier and easier than hanging gutters.

Device Features

According to the method of arrangement and the location of the structural layers, experts distinguish two types of flat roofs:

Classic;
Inversion.

The classic roofing "pie" is equipped according to the following technology:

on reinforced concrete floor slabs, they make a ramp out of a cement-sand mortar;
lay vapor barrier and insulation;
lay down waterproofing membrane or ruberoid carpet;
if the coating is to be used, then the waterproofing is protected with ceramic tiles.

Classic flat roof structure

The main disadvantage of the traditional design is the vulnerability of the outer insulating layer to solar ultraviolet radiation and temperature changes.

Working on a solution to this problem, engineers came up with the idea of inversion coating. In it, the main structural elements (insulation and waterproof membrane) are interchanged. Waterproofing is hidden under the foam, which from external influences protected by gravel ballast or tile trim.

Inversion coating design

Accordingly, the technology of work is changing. A waterproof carpet made of roofing felt or an EPDM membrane is glued onto the slab or spread on it, fixing it at the junction with the parapet.

The slope in this case is created in one of two ways:

Mortar screed on the plate;
Insulation, changing the thickness of its installation.

Installation of thermal insulation on a flat roof

Water intake funnels and pipes are installed at the lowest points of the slope. In addition to them, ventilation is installed to remove water vapor that accumulates in the zone of contact between the vapor barrier and the insulation.

When arranging a coating designed for planting plants, the construct is supplemented with an upper layer of waterproofing. Drainage layers of gravel are poured along it, geotextiles are laid and a fertile layer of earth is poured.

In addition to roofing laid on reinforced concrete slabs, projects have been developed for houses with a flat roof on wooden beams.

Construction technology in this case may include the following operations:

Beams are mounted on the walls in increments of 50-100 cm, fixing them to the masonry with anchor studs. The cross section of the beams depends on the width of the span, the design load and can range from 10x20 cm to 15x25 cm;
OSB boards are laid along the beams, tightly joining them together;
Spread the waterproofing membrane in 2 layers, gluing the joints of the canvases with high quality.
They make thermal insulation from durable (extruded) foam plastic, gluing it to the membrane. A slope for water flow is created by laying the insulation in layers of different thicknesses;
Thermal insulator on top cement screed, reinforced mesh or tiled.

Examples of private houses

Among the developers there are many supporters of flat roofs. They are attracted by the ease of construction, the low cost of work and the possibility of placing a site for summer recreation.

A thick layer of snow on a flat roof is not a problem, but additional insulation

The design of buildings with such a roof fits perfectly into the style of minimalism, providing project developers with a wide field for creativity.

Spacious, comfortable and nothing more - the motto of everyone who chooses a house with such a roof. A pitched roof visually makes the building heavier, while a flat one, on the contrary, makes it light and airy.

The appearance of the facade of a one-story house with a flat roof compares favorably with the fairly boring variations of the "teremkovo" character.

On it, most often you will not see gutters and pipes, the water from which gets on the walls and spoils the appearance of the finish. Internal drainage is effective, practical and invisible.

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

By and large, "flat roof" is a rather arbitrary name. There should always be a small but mandatory slope. Otherwise, rainwater or water after snowmelt will accumulate on the roof, which, in the end, will lead to serious troubles and costs for repairing not only the roof, but also interior spaces.

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

Let's try to figure out how expedient the choice of a flat-roof house project is in our area. To do this, you need to imagine the advantages and disadvantages of this type of roof.

Advantages of a flat roof

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

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

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

Flat roof house project: is it worth it?

It can be said quite definitely that with careful design study and competent work builders erecting a house with a flat roof stands. In the end, you get original housing with additional square meters of usable space and save money on construction work and materials. And the Dom4M company hopes that you will live in a comfortable home for many years. comfortable home built according to our design.

Not everyone likes modern construction. This is immediately clear when flat roof house designs are mentioned in a conversation. Most developers do not like the look, 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 written off as scrap, 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 internal location 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 are obtained and one does not 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

In spite of negative feedback about such houses, their vast majority remains unfounded. Many people do not know that due to the lack of a 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 winter time years will have to be repeated cleaning works. Despite its porosity, snow has a serious mass and in large numbers can easily destroy the entire building.

Large heat losses. 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 like these:

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 shouldn’t 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 in order to thermal insulation boards under the weight they did not deform and always performed their functional tasks with high quality.

As for breathable roofs, they can be traditional or inverted in their structure, but as additional element aerators or deflectors are installed on them. 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 erected with parapets, the air flow is extremely small.

Find suitable house with a flat roof is not a problem now, just look at the catalog of projects offered by 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 the load-bearing walls are framed, then the ceilings 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 bulk material or bituminous products are laid on it. See what it looks like cottage you can 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 roofing. It is very important to consider the nature of your plane here. For example, if you want to put a gazebo, then it would be nice to cover the area adjacent to it with grass or flowers, and make the approach out of 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 a screed, this is the ideal 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 way the erection of buildings is very popular in hot countries, but it is not quite 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 heavy weights, the main thing is to distribute them in a quality manner.

On the roofs frame houses light materials are often laid. 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 pie 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

Project modern home 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 a very effective heat-insulating material, but its 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 decide this problem it is possible 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. AT this device includes such elements as: risers, outlet pipes, water intake funnels. It should be noted that the gravity system cannot boast of high performance, therefore, when heavy rain she may have problems, resulting in a huge puddle 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.

Projects of one-story houses with a flat roof

Now that you understand flat roof buildings, you can start looking at some projects.

Rectangular house with garage

The total living area will be about 168 square meters. The foundation is made of MZFL slabs or piles are placed. The roof is flat, and is used as a covering pvc membrane or bituminous products. The number of living rooms in this project is 3 pieces. Gutter system internal. The building has no basement. Garage is present.

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. Need to define functional purpose terraces: whether they will be designed for the movement of people or cars, or an additional soil layer will be needed here for planting. 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.
