Traditionally, metal roofing has been insulated during install with furring strips to prevent condensation. The insulation keeps the metal roofing panels from reaching a dew point temperature that creates condensation.

If a metal roofing wasn’t installed with furring strips and insulation, there is a patent membrane product on the market that can be added afterwards. They attach this membrane to the underside of the metal roofing panels. This membrane has a rubber backing with felt-like material and will trap and hold moisture that typically results in condensation forming.

Other choices in commercial structure roofing are typical for a flat roof and include EDPM, PVC, and TPO. For a commercial building with a pitched roof, metal roofing is ideal. It can be made to look as antique and classic or as clean and modern style as the building’s architectural style.
