The answer to 'my fascia is failing' is that the fascia board, which is the horizontal board that runs along the roofline, is deteriorating or coming loose. This can be caused by a variety of factors, including water damage, rot, insect infestation, or general wear and tear over time. Some common symptoms include visible cracks, warping, or sagging of the fascia board.
Addressing a failing fascia is important to protect the structural integrity of your roof and prevent further damage to your home. In some cases, the fascia can be repaired by a skilled DIYer, such as replacing damaged sections or securing the fascia more tightly. However, if the damage is extensive or the fascia is difficult to access, it's generally best to call in a professional roofing contractor to assess the issue and provide the appropriate solution.
