Buildings with flat roofs are a trend that is rapidly gaining momentum in the low-rise housing construction segment. Not so long ago, it was believed that roofs without a slope belonged to utility buildings or typical urban high-rise buildings.
However, technology does not stand still, and at present, all these fears and fears are without any foundation. Moreover, flat roofs are regarded as a very attractive and cost-effective solution, allowing you to save money on roofing work and gain additional usable space at the very top of the house. However, first things first…
Roofs with a slope of up to 2.5% are considered flat
The main distinguishing feature of such structures is the absence of a truss frame since the ceilings rest directly on the walls of the building. This, on the one hand, greatly simplifies and, consequently, reduces the cost and accelerates construction processes, and on the other hand, expands the prospects for the functional use of the surface.

Of course, the installation of a flat roof is not at all as simple as it might seem at first glance. Indeed, to make such a roof truly hardy, reliable, and protected from leaks and cold weather, it is necessary to know and put into practice all the nuances of the construction of such structures. Moreover, many features of the construction are determined by the functional properties of structures.
Those who decide to give preference to a flat roof, first of all, should ask the question Roofing Contractors NYC: Will the roof surface serve as an elementary protection against external influences, or is it planned to be used for any additional purposes? The solution must be built into the design at the design stage since each option involves testing with different loads. According to this criterion, flat roofs are divided into:
Unexploited flat roof
They do not involve the use of space, allowing only maintenance during repairs, as well as the removal of debris, dry leaves, and snow. Particular attention in such structures is paid to waterproofing, which acts as a finishing coating.
A group of Roof Repair Contractors NYC models designed for active use as a usable space. Such structures are characterized by increased demands on the load capacity, and the composition of their structure is determined by the nature of the operation.
A traditional roof is an example of a non-exploited structure, but its main essence lies in the order of alternating layers of roofing carpet. This version of the roof can be non-insulated and insulated. In the first case, in a residential building, it is assumed that there is an intermediate technical space under the roof that performs a heat-insulating function. The insulated version uses several heat protection layers in the roofing cake. Moreover, the classic version involves first laying insulation and at the end – waterproofing material.
Inversion is called a kind of “changeling” of the roofing carpet. Unlike the classic solution with an upper waterproofing layer, here the waterproof sheet is laid immediately, on top of the ceiling. Due to this, the material sensitive to mechanical stress is protected from damage. That is, Empire Construction NY are talking about one of the options for the exploited design. An inverted roof is an extremely promising model if it is planned to green the roof, as well as to arrange large objects.
Green roof – a subspecies of the inversion structure, involving the use of soil for sowing grass. The advantage of this solution is the original design of the roof and the possibility of creating a cozy recreation area, as well as increasing heat and sound insulation in the premises. The structure of the roofing pie is formed from a heater, a geotextile fabric, and a drainage and filter layer, on top of which fertile soil is poured. There are two types of green roof organization: expansive and intensive*.
Breathable (ventilated) roof
The device of a ventilated roof provides for the presence of an air gap between the insulation, laid in a classical way on the ceiling, and the remaining layers of the roofing carpet. This approach to the arrangement of the roof structure allows you to protect the insulation from moisture due to additional ventilation. A ventilated roof is an attractive opportunity to extend the life of the structure by preventing the formation of mold and fungi. In addition, the device prevents the formation of icicles along the edges of the eaves and contributes to an increase in the energy efficiency of the living space.
Flat roof ceilings are installed on the walls of the building, and, depending on the design solutions, the span and operational orientation, reinforced concrete, corrugated board, or wood are used for these purposes. As mentioned above, the structure of the roofing carpet is characterized by diversity, therefore, the order of laying the layers for each type of system is different. Consider the general scheme for arranging a flat roof, without affecting the structure of the coatings.
