The 6 leak sources we find most often on Huntsville-area roofs.
1. Pipe boot flashing
The rubber gasket around plumbing vent pipes cracks within 8–12 years in Alabama sun. It's the #1 leak source we find in Huntsville and Madison.
2. Chimney flashing
Step flashing eventually fails as it ages. Caulk is not a fix — proper flashing replacement is.
3. Valley leaks
Where two roof planes meet, debris collects and ice/water shield ages out. Valleys are a common late-life leak source.
4. Wind-creased shingles
Often invisible from the ground but very common after Tennessee Valley wind events — the shingle stays in place but no longer seals.
5. Skylight perimeters
Skylight flashing kits have a 15–20 year service life. After that, perimeter leaks are common.
6. Ridge cap and roof-to-wall transitions
Both are vulnerable spots where shingles meet vertical surfaces or the peak of the roof.
