Learn more →Repair or Replace? How to Decide
Repair often makes sense when
- Damage is limited to one area
- The rest of the shingles lie flat and intact
- The leak traces to flashing or a vent
- The decking is still solid
Replacement may be better when
- Curling or bald shingles cover many slopes
- Leaks keep appearing in new places
- Decking feels soft or sags
- Several old layers are already on the roof
