Tent roof for almost all Europeans is more familiar than horizontal. But in many Asian, Mediterranean countries, such a roof is common. Both options have advantages and disadvantages. Until recently, it was believed that the pitched construction is more suitable for harsh conditions. The flat roof was commonly used for high-rise buildings. Floor slabs in terms of strength, reliability, durability made it unnecessary to install truss systems for hipped roofs.

Why did the flat roof become the trend of the new time?

A characteristic drawback method was insufficient waterproofing. The flow brought a lot of trouble to residents of the upper floors. A flat roof in a private house was extremely rare. One of the main reasons for refusing this method of roofing was the impossibility of guaranteeing high-quality waterproofing. Existing roofing materials mounted on a horizontal surface was impractical.

Today, a flat roof can be technologically installed using market materials. The product range allows you to successfully cope with technical tasks and at the same time achieve the aesthetic goals of the project. What is a flat roof in a private house, the pros and cons? Why today designers and homeowners pay attention to this design?

Advantages of a flat roof

In warm countries, a straight horizontal roof often not only had protective properties, but also solved functional problems. The place was used as a dryer for food, vegetables, fruits, berries. An additional light canopy allowed to exploit the area for household needs, recreation and meals. For a hot climate, a flat roof was preferable to a sloping counterpart. The gaining popularity of the trend of recent decades for residents of continental Europe has been the installation of a flat roof. Owners of this design receive the following benefits:

  1. Additional usable area.
  2. Original building design.
  3. No cost for installing a truss system and purchasing traditional roofing materials.
  4. Smaller area for installation and finishing works.
  5. A simple construction, during the construction of which there is no need to use the services of expensive specialists.
  6. Security installation. The worker is on a flat horizontal surface, and not on the ramp.
  7. The flat roof is more resistant to wind.

Designers readily enjoy the benefits of a flat roof and offer additional options for expanding their operation. For example, popular projects with a pool. It is not necessary to build a stationary structure. The market has enough mobile products of this class, which is easy to install and then dismantled. The result is an ideal place for a mini-beach. Here you can swim and sunbathe.

Disadvantages of a flat roof

After evaluating the advantages of the structure, it should be noted that such a performance has disadvantages. A major problem can be precipitation. The greatest danger is snow. In regions with a large amount of precipitation during the winter period, a timely cleaning system should be thought out, or a possible roof load should be laid during the design. For central Russia, this problem is relevant. When choosing a method of roofing this nuance should be indicated. The project also includes a drainage system. It is somewhat more complicated than that of a pitched roof. The channels are installed at the maximum possible angle, and the surfaces are unraveld to efficiently remove moisture. Special attention is paid to the roofing pie. High demands are made when choosing a material, installation technologies are strictly followed.

Snow poses a danger to flat roofs

If a regular and sensitive load on the structure is assumed, then it is better to trust the calculations to a professional. A guarantee of strength is required. The height of the plane of the roof above the ground forms another important task - the need to install fences. The issue of safety for the health and lives of people should not be in the first place. The height, shape of the fence should eliminate the risks of an accident not only for adults, but also, and most importantly, for children. The lack of protective structures is a serious disadvantage.Such a flat roof in a private house can not be used for recreation and entertainment. The disadvantages include the inability to equip a closed useful space under the roof, such as an attic, an attic.

Variants of a straight horizontal roof

The evolution of technology has made it possible to use several types of flat roof installation . The materials used belong to different classes and categories, but all of them should be designed specifically for the installation of roofs. It is accepted to divide a flat roof into two main types - operated and not operated. Depending on the option chosen, appropriate materials are selected. The manufacturer in the manufacture of products lays the necessary qualities that make the roof able to withstand physical and climatic stress. Today the device of a flat roof of a private house can be made in the following variants:

  • Prefabricated floor slabs.
  • Reinforced concrete monolith, which is carried out directly during construction.
  • Complex multi-layered roofing pie.

The last option is the most difficult. It is used for light frame structures and is a set of insulation, waterproofing, bearing plane, roofing material. Most often, industrial floor slabs are used, but they can only be installed on houses where the walls are made of bricks, blocks of different composition. Installing a flat roof on a wooden house is not an obvious solution. It is difficult from a technical and not always justified from an aesthetic point of view. However, in cases of exclusive design, such an idea can be successfully implemented.

Materials for flat roofs

An important task in the planning and procurement phase of component parts is the right choice. Has the construction of a house with a flat roof, pros and cons, and in order to identify the best qualities and level the disadvantages, you should observe the following rules:

  • Acquire insulation for facade works.
  • Use insulation for roofing during installation.
  • To accurately calculate the expected load on the supporting structure of the house, it is especially important when the house is frame or made of CIP panels.
  • Roofing material is selected that is designed for the load when people or objects are on it.
  • Use a specialized drainage system.
  • Acquire fences with increased reliability and durability that can withstand the operational load.

The choice of building materials for the arrangement of the roof should be approached responsibly

The choice of insulation

As insulation Foamed polymers are used - polystyrene foam, non-polyurethane, polyethylene foam and other similar materials. Traditionally used clay. It is resistant to stress and does not require a thick screed. The use of mineral, basalt wool is considered a modern and effective method. The material is light, has a low coefficient of heat transfer, a high level of sound insulation is achieved. The main disadvantage of this product category is hygroscopicity. Mineral wool absorbs moisture, so it is recommended to use reliable waterproofing materials.

Useful decor

If it is technically possible, then the roof surface may be trimmed with decorative materials - tiles, paving stones, panels, slats, and boards for outdoor use. An integrated approach to roofing is widely used. Part of the building has a traditional hip shape, and the other part is designed as a flat roof. In some cases, part or all of the surface is covered with turf or other plant species. The operated roof involves high loads, so special attention is paid to waterproofing. Best results are achieved with several layers of protection. Roll, sheet materials are purchased in the relevant indicators. Well-proven method of seamless installation. Bulk polymer compositions today look the most attractive for this operation.
