The answer to 'why is my fascia' is that the fascia board on your roof may be damaged or deteriorating. The fascia is the horizontal board that runs along the edge of your roof, just above the gutters. Common causes of fascia issues include weathering, water damage, woodpecker or insect damage, or improper installation. Symptoms include sagging, cracking, peeling paint, or rotting wood. Solutions may involve repairing or replacing the fascia board, which is a job best handled by a professional roofing contractor.
Fascia damage can lead to further roof and gutter problems if left unaddressed, so it's important to inspect it regularly and address any issues promptly. While some minor fascia repairs may be doable for a handy homeowner, extensive damage or replacement is typically a job for a skilled roofer who can ensure the work is done properly and safely.
