Hiring a roofer in Diamond Bar
Tile is everywhere in the San Gabriel Valley, so ask any bidder to price a lift and relay before a full tear off. Older homes here often sit on skip sheathing, which changes what the deck work costs.
Start with three bids. Line the scopes up next to each other before you look at the totals, because a low number usually means a smaller scope rather than a better price. Check the license, confirm workers compensation coverage, and keep the deposit inside the state cap of one thousand dollars or ten percent.
California licenses roofing contractors through the Contractors State License Board. Look up a license before you hire.
