Flat Roofing by Blair Roofing
Charlotte, NC commercial roofing
As opposed to your typical residential roof, commercial and industrial roofing is often flat, which raises new challenges when dealing with rain, snow, or any other forces of nature. While your typical residential roof contains sharp downward angles which allows the elements to roll off into the gutter, run-off must be dealt with in other ways when a flat roof is installed.
Despite being called a flat roof, a slope of anything less than 10 degrees in pitch is still considered to be a flat roof. This helps to solve the problem of standing water on the roof mentioned above, as slight angles can be used to help direct run-off to a gutter on the edge of the roof.
How is a flat roof installed?
Unlike standard residential roofing protected by shingles, a flat roof must be constructed by using many individual membranes, or roofing panels. These panels are connected by heating the edges to allow them to become soft, and placing them together before they cool. Depending on the specific type of material the membrane is made of, the membrane can either be reheated and cooled again (thermoplastic) or can only be heated and cooled once before locking into place (thermoset).
