That is the modeled cost to deliver plus a fair contractor margin, not a sales quote. Built from BLS metro wages, Craftsman labor hours, a real bill of materials, and hand-verified permit data. 2026-08-28
Mid-range here means the reroof most homeowners actually buy: full tear-off and asphalt shingle replacement on a typical single-family roof, disposal included, with up to two sheets (64 sq ft) of decking replacement in the base price. Additional decking prices per sheet. Metal, tile, and slate are the premium rungs of the same job.

The margin is the gap between break even and a typical quote, not a markup we invent. Margins float by trade and city, with most fair jobs at a 15 to 22 percent margin on the bid, about 18 to 28 percent over the cost to deliver. Nobody works for free. Full methodology.

This page shows where a San Francisco bid sits when the permit can outlast the job and the labor rate is set by the hall.
Numbers on this page come from Craftsman labor hours, BLS OES May 2025 wages for San Francisco, FRED material prices, and the verified local permit fee. How we calculate
Local Market
San Francisco roofing costs reflect one of the most union dense construction markets in the country. The labor portion runs high because of that density and the hall structure that supports it. Our data shows 71.8 craftsman hours at a loaded wage of $63.20 per hour. That loaded rate includes the $42.10 base plus the 50.1 percent burden for taxes, insurance and benefits. The result is $4,538 in labor alone. Add $5,161 in PPI adjusted materials, the $309 permit fee from PermitCalculator.com and $4,541 in overhead and disposal. You land at a cost to deliver of $14,549. The 23.8 percent contractor margin is the gap between that delivery number and the $19,105 city average. Those long permit timelines for bigger projects create real holding costs that push prices higher even when the roof itself is straightforward replacement. Nearly half the housing stock here dates before 1940. That old stock means surprises once the tear off starts. The numbers reveal a market where union labor and old homes drive the premium you pay. (BLS OEWS wage input) (Craftsman, 2026)
San Francisco carries some of the highest union labor costs I've seen on paper. That loaded rate near sixty three an hour explains a big chunk of why the average job lands around nineteen thousand. In my old Missouri crews we paid a good bit less than that and still turned a living. Different markets different realities. Sounds about right for the Bay Area.
Understanding Your Bid
Some San Francisco roofing bids make no sense. The average sits at $19,105 while the verified floor reaches $16,529. That leaves $2,576 of potential savings between them. The contractor margin on the average bid is 23.8 percent, on top of the $14,549 cost to deliver. Some contractors earn every penny of that margin. Others pad the bid with soft numbers on disposal or overhead. A quote near $16,529 deserves serious attention if the crew is solid and the scope matches. Anything well north of $19,105 needs line item scrutiny. The union labor market here means wages don't fluctuate much. So when a bid deviates sharply it's rarely because the roofer found a magic labor deal.

Cost Breakdown
Break the $19,105 average down and the pieces tell a clear story. Labor takes $4,538. That comes from 71.8 craftsman hours at the local loaded wage of $63.20 per hour. The base BLS wage is $42.10. Add the 50.1 percent burden and the math lands exactly on $4,538. Materials add another $5,161 according to FRED PPI inputs. The verified permit fee is $309. Overhead and site costs including disposal run $4,541 per NAHB benchmarks. Add it up and you get the $14,549 cost to deliver. Everything above that's margin. In a city where a large share of homes predate 1940, crews often discover rotted decking or hidden flashing issues once they start tearing off. That turns a cosmetic quote into a larger job fast. The seismic questions come up too. Earthquake brace and bolt retrofits come up on pre-1979 homes. Those realities live in the numbers. The floor of $16,529 represents the lowest realistic out the door price after a lean but sustainable margin. (FRED PPI, 2026) (PermitCalculator, 2026)
That about forty five hundred in overhead and disposal looks honest enough on a twenty five hundred square foot tear off. But in a city with forty five percent pre 1940 homes you better verify the decking condition before you sign. I've cut out more rotted sheathing than I care to remember. Ignore that line and you'll pay twice.
How to Negotiate
Shop your San Francisco roofing job in the slower winter months if you can. Demand drops and crews look for work which creates breathing room on price. Get bids from at least three established local roofers. Know exactly where that quote sits against the $19,105 average and the $16,529 floor. Ask the contractor to break out labor hours, material specs and disposal costs separately. A fair roofer will walk you through those items without hesitation. If the bid ignores the $309 permit or inflates disposal beyond the overhead allocation in our data push back. The goal isn't to beat the contractor down to the floor. It's to pay a defensible price for quality work that lasts in this climate. Do that homework first and the conversation changes.
If a roofer quotes you over twenty one thousand on a standard asphalt replacement and can't explain the disposal or the deck repair add on walk away. In this market the slower winter window gives you leverage. A fair contractor will show you the material invoices and the exact hours. Take that to the bank and pay the man his money today before he backs out on you.

What Makes This Market Different
San Francisco stands apart because the permit process can outlast the actual roofing job. The dual agency structure between Planning and DBI turns even simple alterations into four to twelve weeks of plan review. For bigger work the timelines stretch far longer. That reality sits on top of the highest union density in private construction anywhere in the country. Labor isn't a rate here. It's a scale enforced through the hall. Add in the fact that nearly half the homes were built before 1940 and you get a market where old balloon framing, buried asbestos or knob and tube wiring turn up the moment the tear off begins. The all electric ordinance that kicked in for major renovations in July 2026 doesn't hit a straight asphalt shingle replacement. But it shapes the larger conversation about what else gets touched on the house. I have never seen another city where earthquake bolts are a normal contractor question during a roof bid. The soft story retrofit rules for multifamily buildings and the brace and bolt grants for single family homes create a constant seismic backdrop that national calculators simply ignore. These factors make roofing costs here feel different in the hand. The numbers reflect that.
