Roof rot occurs when wood parts of the roof, such as the decking, are exposed to excessive moisture for extended periods of time. The decking connects the roof to the rest of the home, supporting the weight of shingles and other roofing materials. If the decking absorbs too much water, it will start to decay and rot.
Rotting wood can lead to significant issues, such as a collapsed roof or the spread of wood rot to vital structures that keep your house standing. If you suspect water is penetrating your roof, you’ll want to have a professional roofing company inspect your home right away.
