Commercial Flat Roofing
A flat roof – otherwise known as a low-pitched roof – is a type of building covering that is horizontal or nearly horizontal, as compared to the traditional sloped roof. Membranes are materials used to cover a flat roof. The purpose of membranes is to waterproof the roof by allowing water to flow through a slight inclination into a gutter system. This will not just waterproof the roof, but will also keep the walls and foundations dry.
Most flat roofs are built of tar or tar paper applied over roof decking to keep a building watertight. It is then covered with gravel to block the sun’s heat and UV rays, as well as to protect it from blistering and degradation. The roof decking is usually made of plywood, chipboard, or Oriented Strand Board that is around 18mm thick.
Flat roofs are suitable in areas that do not get too much rain or are unlikely to experience freezing. This is not only good for keeping the heat at tolerable levels inside the building, but is also cheaper and easier to build – especially in places where timber is not readily available. However, flat roofs are not recommended in places that get a lot of rain and freezing. This is because water can flow into the brickwork and freeze, which can result to “blowing” or the breaking up of the concrete due to the expansion of ice.
Flat roofing is a popular choice because of its affordability and durability. To protect it from weathering, it is important for building owners to have it checked regularly for leaks.
