Brentwood FAQ
Concord FAQ
Do I need a permit for a simple roof repair in Concord?
Minor repairs of less than one roofing square (100 sq ft) of like-for-like material are generally exempt, but any tear-off, recover, or structural repair requires a permit from the Concord Building Division.
Can I add a second layer of shingles on my Concord home?
A single recover (overlay) is permitted if the existing roof is sound and has only one layer. If two layers already exist, a full tear-off to the deck is required.
How long does a reroof permit take to issue?
Over-the-counter issuance is typical for standard residential reroofs when the application is complete and the contractor is active with the CSLB.
