Why Walnut Creek is Walnut Creek
Lots of 1960s and 70s homes here are on their second or third roof, and Rossmoor has its own paperwork, which the roofer handles.
What moves the number
- 1How steep and how cut up the roof is. A simple ranch roof is cheaper than the same square footage with dormers and valleys.
- 2Material. Standard shingles sit at the bottom of the range. Designer shingles, tile and metal climb from there.
- 3How many old layers come off. Tear-off is real labor and real dump fees, and it is where cheap quotes quietly skip a step.
- 4Access. If the crew cannot park a truck near the house, you pay for the walking.
