The answer to 'why is my roof decking' is that the roof decking, which is the structural layer below the roofing material, can become damaged or deteriorated for several common reasons. Some of the most frequent causes include water damage from leaks, rot from prolonged moisture exposure, and structural issues like sagging or warping.
Symptoms of roof decking problems may include soft or spongy spots on the roof, visible cracks or holes, and uneven or sagging areas. In some cases, the damage may be hidden and only visible from the attic space. If left unrepaired, damaged roof decking can lead to more serious issues like roof collapse or water intrusion into the home.
