The space of a country house is largely limited by standard tent roofs forming an attic or attic. At first, the problem was solved using the attic floors. However, the development of technology and the advent of waterproofing made it possible to build houses with a flat roof. Typical designs for such a home are offered by most developers. The unusualness of these buildings is fully justified by architectural features and practicality.
Benefits of Flat Roofs
Well-equipped area on the roof of the building can be used for various purposes, depending on the wishes of the owners. However, the main goal remains to protect the house from rainfall, ensuring the durability and reliability of the building.
Advantages of flat roof house projects:
- Simplicity and speed of installation. The construction of the roof does not require the creation of a lathing and the use of lumber, it is carried out in one plane without insurance and scaffolding. This approach saves resources, finances and time.
- The flat roof design is durable, tough and does not require frequent maintenance. A long service life is ensured subject to technology, features of projects of houses with a flat roof, competent arrangement of gutters.
- High level of thermal insulation.
- Convenience of installation and maintenance of additional equipment.
- The refined design of the facades of houses with a flat roof, the completeness and clarity of the lines.
- The possibility of equipping the roof for various purposes - leisure, sports or hobbies.
disadvantages
The main disadvantage of a horizontal roof is the risk of leakage. Snow that has fallen during the winter during thawing can destroy the walls of the house, which is typical for improperly mounted roofs. When performing all work according to the technology, there will be no such shortcomings.
The second minus is the accumulation of snow on the roof, which will have to be cleaned manually if access to the equipped sites is planned. Accordingly, the construction of houses with a flat roof can be trusted only to professional developers with good reputations, providing a guarantee for the work performed.
Projects of houses and cottages with a flat roof
The configuration of a flat roof is not only original, but also functional, and there are a lot of its types. All of them are divided into two categories: exploited and non-exploited. Each of the subspecies can be performed according to traditional, classical or inversion technology.
Operated
Erected not only to protect the house, but also to increase its usable area. Their surface should be smooth and strong with a slope of up to five degrees, necessary for the flow of water. The preference for projects of wooden houses with a flat roof of an exploited type is given largely due to their additional functions.
Unexploited
They do not need a rigid insulation and a base for waterproofing, which simplifies their design. On the roof, as a rule, have bridges and ladders for even distribution of the load. This type of roof is cheaper in construction, but has a shorter operational life in comparison with the exploited options.
Design differences
A flat roof consists of several alternating layers of hydro, thermal and vapor barrier. A feature of the planning of projects of houses with a flat roof is that such dwellings have additional roof layers that increase strength.
Under a classic flat roof is often meant soft. A feature of its design is the external arrangement of the hydro-insulation layer. The bitumen component provides softness to the coating. The disadvantage of this solution is the constant effect on the upper layer of temperature differences and ultraviolet rays.
Their effect is especially destructive during the period of frost, when at night the temperature drops below zero, and during the day it rises. Over time, this leads to the destruction of the waterproofing and moisture from rainfall on the concrete base of the roof and walls of the building.
An inversion or lightweight flat roof was developed taking into account classical errors. Inversion of the layers of the structure significantly increases the period of its operation and maintains the state of the waterproofing coating. When creating such a roof, the concrete base is initially treated with insulation, on top of which a layer of hydrophobic insulation with a coating in the form of pavers, gravel or gravel is placed. The insulation of the inverse roof is of such a high quality that you can lay paving slabs on it or break a lawn there.
Roofing Projects
Before building a wooden house with a flat roof, first of all, its type is determined - whether it is exploited or not exploited. They differ not only in design and operational features, but also in cost: the first option requires the construction of a reinforced foundation and load-bearing walls that can withstand the weight of reinforced concrete floors.
The aim of the project is to calculate the loads on the building and determine the amount of necessary building materials. Design helps to draw up a work plan. For its implementation, professional specialists are involved.
Design stages
Project activities are divided into several stages:
- Drawing up a sketch of the building. Designers receive from the builder the linear parameters of the object and a list of materials, after which they calculate the weight of the building and the load exerted on the foundation. This allows you to correctly determine the snow and wind loads, adding to the total weight.
- Calculation of supporting structures. It includes determining the number of beams, their length and cross-section to create a crate.
- The plan diagram. It indicates the basic structural elements and their location.
Wooden houses with a flat roof are designed in various styles, but hi-tech is considered the most functional. The building can be small, designed for a couple, or it can be an extensive cottage with several terraces.
With the exception of the architectural and construction project, specialists usually order a work plan that takes into account all the features of the house. This allows you to determine the total cost of housing being built.
What is taken into account in the plan
Despite the apparent simplicity, flat roofs on modern frame houses are built from various elements, the selection and installation of each of which requires certain nuances to be observed:
- Junction nodes. Areas in which vertical and horizontal planes intersect - chimney walls, sides, ventilation and others. The connections of the junction nodes must be completely tight and performed in compliance with all technologies.
- Cornices They protect the walls and the blind area of the house from moisture flowing from the roof, and give the building an architecturally finished look. The width of the cornice varies from 0.5 to 1 meter, depending on the climatic conditions of the region of residence.
- Drainage funnels. Designed to drain water that accumulates in low sections of the roof. On average, one funnel is installed on the roof for every 0.75 m 2 of area.
- Windbreakers and aerators. Structural elements designed to remove water vapor generated inside the coating.
- Lightning rods. Performed in the form of vertical lightning rods or horizontal mesh.
- Drainage system. There are two types - external and internal. The first type is simpler in terms of design and operation and much cheaper.
Best flat roof house design ideas
When choosing a building project, not only its architecture and size are taken into account. Particular importance is given to the materials of ceilings, roof construction and the possibility of increasing the usable area due to it. The best houses with a flat roof are:
- in high-tech style;
- one-story;
- two-storied;
- cubic;
- wooden etc.
High-tech two-story house
The design of the high-tech building involves insulated walls built of ceramic blocks and aerated concrete. A two-story house with a total area of 150 m 2 is designed for the installation of a flat roof of an operated type.
The project is lightweight and compact, suitable for families with children. It belongs to the middle price category.
The upper space is divided into two parts, in one of which technological equipment is located. The facade design of the flat-roofed house can combine textured finish with smooth walls.
Cottage
The Archiline compact one-story wooden house with a flat roof design is ideal for small families. The warmth and comfort of a home can be achieved through panoramic windows, south-facing living spaces and underfloor heating.
A roof slope of several degrees provides a drain of melt and rain water and allows you to safely walk on the roof. The type of roof in use increases the usable area of the building. The long service life of not only the roof, but also the building is provided by a PVC membrane and a monolithic overlap. It is possible to emphasize the area of the premises and give the building a modern look thanks to the flat roof.
Large two-story house
Modern construction technologies are aimed at the construction of reliable, high-quality and warm houses for a large family. With the competent installation of a flat roof, its heat and waterproofing, it is possible to increase the useful area of the building. Monolithic ceilings and aerated concrete walls retain heat in the house.
Despite the fact that the buildings erected on such a project have a significant area, because of the flat roof they look more neat and light.
Cubic houses
The square houses with a flat roof, made in the architectural style of Cubism, look stylish and attractive due to the lack of a high hipped roof.
Two-story houses of this type are often equipped with corner glazing and attract attention due to the unusual architecture. The cubic style is emphasized by a flat roof, which is a continuation of the entire building. Such houses are being built from sandwich panels, providing strength and thermal insulation of the structure as a whole.
Wooden two-story houses
The use of exclusively modern materials is not always preferable, since many choose the timeless classics - wooden houses with a flat roof. Such buildings are not only ecologically sound, but also aesthetic.
Two-story houses are built of high-quality timber and have no less heat and waterproofing than similar buildings made of modern materials.
When to choose a house with a flat roof
Projects of houses with a flat roof are laconic, aesthetically pleasing and efficient use of free space. This type of roof can significantly increase the useful area of the building. Houses with a flat roof are chosen if preference is given to the listed criteria. During their construction, the main thing is the choice of a professional builder with good reviews, able to comply with the technology and draw up a correct project, which will take into account not only the wishes of the customer, but also other construction nuances.
