In Southwest Florida, damp fascia is an invitation for termites and other wood-eating insects. They often work from the inside out, so the board can look fine from the ground while the core is hollow. When we replace fascia, we look closely at the exposed wood and the rafter tails for signs of insect activity. If we see evidence of termites, we will point it out so you can have a pest professional take a look before the damage spreads.
Hidden damage is also common at corners and where roof sections meet, because water collects there. These spots are easy to miss from the ground, which is why we check the full length of the roofline and not just the area you noticed.
Replacing the bad wood and then protecting it from future moisture, with flowing gutters and, if you choose, aluminum wrap, is the most reliable way to stop the cycle of rot and repair. It also gives your gutters a strong edge to hold onto during the heavy summer storms we see every year.
