Roofing in California
Roof work is expensive and hard to judge from the ground, which is why comparing more than one written bid matters. On GroundBid you describe the job once and licensed roofers send private bids you can compare side by side. GroundBid is open to homeowners and businesses across California.
What's typically included
Roof repairs and leak fixes, re-roofing and full replacement, flashing, vents and gutters connected to the roof, and inspections after storms.
What to include in your project post
Say what the roof is made of (shingle, tile, metal or flat), roughly how big it is, how many stories the building has, where water is getting in if there's a leak, and whether you have photos of the damage or an insurance claim.
Checking a provider in California
On GroundBid, roofing is a licensed trade: a provider must have a verified state license before they can bid.
You can also check a contractor's license yourself with the Contractors State License Board (CSLB): official license lookup · 800-321-2752. California licenses contractors statewide through the CSLB. Its lookup shows a contractor's license status, classifications, bond, workers' compensation, personnel and any discipline.
Licensing and permit rules can change and vary by city and county. This is general information, not legal advice; confirm with the licensing board or your local building department. License lookups for every state →
How GroundBid works
Describe the project with photos, choose how long bidding stays open, and verified providers send private, sealed bids that other providers can't see. Compare them, accept the one you want, and your payment is held until you confirm the work is complete. How sealed bidding works →
