Is there a typical San Francisco roof price?
Not a useful single number for every house. The 2025 Cost vs. Value report prices a midrange 30-square (about 3,000 square foot) roof replacement in the San Francisco metro at roughly $38,000 for asphalt shingles and roughly $65,000 for metal. Your own roof's price will differ; a free written estimate is the only real number. Inside the city, two houses on the same block can be priced very differently because their roofs aren't alike.
What actually moves a San Francisco bid?
| Factor | Why it matters in the city |
|---|---|
| Flat section behind a parapet | Needs a membrane system, drains or scuppers and parapet flashing, not shingles |
| Access | Shared walls, three-story fronts and no side yard mean hoisting or carrying materials through |
| Street space | The dumpster needs street space, which is handled through the DBI reroofing permit |
| Old layers | Past overlays come off; the code limits recovering (CRC R908) |
| Decking | Rotted or spaced boards found after tear-off need replacing, and replacing sheathing needs an over-the-counter building permit |
| Historic district | Some homes need Planning review before the permit is issued |
Where do I get a ballpark for my house?
Use our roof size and cost-factor tool to estimate how many roofing squares your house has and which factors apply. Then request a quote: a roofer measures, checks the parapets and drains, and prices your exact scope in writing.
How do I compare two San Francisco bids?
Line them up on the roofing system, layers removed, unit price for replacement decking, parapet and drain work, permit and street space, and warranty. A bid that skips the parapet isn't cheaper, just incomplete. Our quote checker walks through each line. Permit details are in the San Francisco permit guide.
How much can a roofer collect up front?
California law caps the down payment on a home improvement contract (CSLB); pay as work is completed.
Every roofer we work with is licensed, insured and highly reviewed by Bay Area homeowners.

How much does a new roof cost in San Francisco?
The 2025 Cost vs. Value report prices a midrange 30-square (about 3,000 square foot) roof replacement in the San Francisco metro at roughly $38,000 for asphalt shingles and roughly $65,000 for metal. Your own roof's price will differ; a free written estimate is the only real number.
Why is a flat roof quote higher than shingles on my neighbor's house?
Flat roofs need a membrane system plus drain, scupper and parapet work, and crews often hoist or carry everything up through the house.
Can you tell me what my roof will cost?
Not accurately without seeing it. Size, layers, decking and access swing the price widely, so a free written estimate from a licensed roofer is the only reliable number.
Is street space extra?
Street space for the dumpster is handled through the DBI reroofing permit; ask that permit costs be listed on the estimate.
What down payment is legal?
California law caps it for home improvement contracts; see CSLB's roofing guide, and don't let payments get ahead of the work.
