The flat roof is a common element in commercial buildings across Texas, but also in more and more residential buildings, with modern architecture.
The Texas climate may seem harsh for this type of roof. However, roofing materials have evolved a lot, and nowadays a flat roof executed correctly from a technical point of view and with the best quality materials will withstand without problems in the weather conditions specific to the Lone Star State.
When designing flat commercial roof, several aspects must be considered, as the roof will be subject to stresses from the outside and the inside of the building. Important external considerations include local precipitation, the effect of the sun’s rays, the weight of the snow, the wind, the various temperature variations and people’s traffic, which may be permanent in the case of walk-on roofs, or temporary in the case of the regular ones.
Per Dallas commercial roofing company professionals, highly trusted products used on commercial roofs include:
BITUMINOUS MEMBRANE
One of the best for preventing infiltrations
The classic method of waterproofing flat roofs is by using bituminous membranes. Laying a black bitumen cover was, and will probably be for a while, one of the solutions for preventing water infiltration in the roof’s structure.
Additionally, bituminous membrane is used against infiltrations in different other construction elements, such as foundations, tunnels, basements, etc. They are also great for restoring waterproofing to the terraces of old buildings and weatherproofing new ones.
PVC MEMBRANE
Flexibility, quick and easy installation, perfect grip
PVC membrane is used in a series of applications, the best known being those of roofs and tanks with clean water. This modern solution is suitable for flat commercial roofs, industrial roofs and much more.
The PVC membrane is fixed mechanically and then by heat sealing (hot air bonding) forming homogeneous connections, of high resistance. The PVC-based membrane withstands strong sun rays and the attack of a variety of organisms, like fungi, spores, bacteria, etc. This solution is preferred for surfaces that need to be kept clean and protected from any biological damage, offering quality weatherproofing.
POLYURETHANE MEMBRANES
Exemplary sealing and resistance to a variety of environmental factors
Polyurethane membranes (created through polymerizing specific chemical compounds) are products designed to be applied in a liquid state. They revolutionized the field of fabricated protective membranes for concrete surfaces, being very popular nowadays due to the very simple application.
Following the osmosis process between polyurethane resins and other chemical substances or compounds, an outstanding type of membrane is obtained, in terms of intrinsic properties for waterproofing surfaces. The results are remarkable and boast the durability and quality necessary for protection against harmful environmental factors.
GREEN ROOF TERRACE
A relaxing space on the roof
Today, the idea of having a green roof terrace is much easier to implement than in the past, due to the development of membranes and multi-layer systems that protect the roof from environmental and climacteric factors and ensure all the conditions necessary for the safe growth of vegetation.
