Understanding Gypsum Roof Decks

A gypsum roof deck, also known as a gypsum board or drywall roof deck, is a popular choice for low-slope and flat roofs. It consists of gypsum panels that are installed directly over the structural supports, providing a smooth and fire-resistant surface for the roof assembly.

Signs of Gypsum Roof Deck Deterioration

Over time, a gypsum roof deck may deteriorate due to factors such as water damage, age, leaks, or inadequate installation. Signs of deterioration include sagging or uneven areas, water stains, mold or mildew growth, and visible cracks or damage to the gypsum panels. It is crucial to address these issues promptly to prevent further damage to the roof and the building’s interior.
