The answer to 'signs of fascia damage' is that the fascia, which is the board that runs along the edge of the roof, can show several signs of damage. This includes cracks, warping, rotting, or sagging fascia boards. Fascia damage is often caused by exposure to the elements over time, as well as potential water damage from leaks or poor roof maintenance.
If you notice any of these issues with your fascia, it's important to have a professional roofing technician inspect it as soon as possible. Fascia damage can lead to further roof and gutter problems if left unrepaired.
