I am a homeowner from Florida and I’m hoping that someone can give me some advice.
I had a new roof installed about 2.5 years ago, and I’ve just noticed that my wooden fascia has begun to rot in a few places due to water damage. After searching around a bit on the internet about fascia replacement, I found that many people recommend a shingle overhang of at least 1/2" over a drip edge. My roofer installed the shingles flush with the drip edge. Being a first-time homeowner, I was unaware of this requirement at the time and I didn’t notice anything wrong. Now, I suspect that the reason for the water rot is due to the runoff clinging to the drip edge, and through capillary-action dripping directly onto the fascia.
Most of the damaged areas appear to be centered around the fascia joints. Now I know that I should have made certain that these joints were properly caulked when I painted the fascia 2 years ago.
How important is having a 1/2" or so overhang? I’m assuming that they didn’t leave an overhang due to fears of hurricane-force winds down here, but I’ve read a few posts on this forum where people say that as long as the overhang is not excessive, it shouldn’t be a problem. When I go about repairing or replacing the damaged areas, should I somehow create a shingle overhang over the drip edge, especially on the lower ends of the roof? How would I go about this? Could I simply add a row of shingles under the starter row?
I don’t want to go through all of these repairs only to have the same problem again next year. Maybe tomorrow I’m going to remove some of my aluminum soffit pieces and poke my head in there to see if any of the damage extends behind the fascia.
