What usually causes a new roof to leak?
- Flashing at walls, chimneys, skylights and pipe vents
- Valleys and low-slope sections
- Exposed or missed fasteners, or underlayment laps
- Gutters or condensation mistaken for roof leaks
Who is responsible?
Installation problems fall under the roofer's workmanship warranty; material defects under the manufacturer's warranty, which may require the original installer and registration. See roof warranties.
What should I do?
- Limit damage and take dated photos of the leak, ceiling and attic.
- Notify the roofer in writing with the photos and ask for a repair date.
- Keep copies of the contract, permit final and warranty.
- If they don't respond, file a complaint with CSLB (CSLB complaints).
Does homeowners insurance cover it?
Sudden water damage may be covered, but faulty workmanship usually isn't. See insurance and roof claims.
