The potential for condensation and moisture buildup in a membrane roof system from interior moisture sources has always been and should continue to be an issue that must be accounted for in roof system design. Furthermore, the color, solar reflectance and thermal emittance of the roof surface can affect a roof system’s drying potential and, therefore, the buildup of moisture in the roof system.
Moisture buildup in the roof assembly can result in deck deterioration, including rotting wood decks, corrosion of metal decks, growth of mold and other organisms, deterioration of the roof system and re-emulsification of certain water-based adhesives. Read more.
