Why flat roofs leak?
Flat roofs are notorious for leaks and many home owners and businesses have constant problems with flat roofs, and trying to repair them, to only have yet more roof leaks just few weeks or months later. Flat roof leaks are caused by the nature of flat roof construction – water pools in some spots and often has nowhere to drain. Any roof penetration is a nightmare for roofing contractors, as trying to properly flash a skylight, HVAC curb or a chimney can be very tedious. Most flat roofing contractors use outdated and often obsolete roofing materials such as Built-up tar and gravel roofing. Many will resort to using cheaper and easier-to-install rubber roofs. All of these older roofing materials have common flaw – the fact that they use some kind of adhesive to glue the overlaps in membrane, and once the adhesive begins to fail, roof leaks start popping up all over the place.
