Is my roof replacement quote fair? A Bay Area bid checker

Short answerA fair roof quote is complete before it's cheap: it names the product, layers removed, decking unit price, flashing, ventilation, permit and warranty, and keeps the down payment within California's legal cap. Tick what your bid includes below to see what's missing, then compare it with a second written estimate.

Every roofer we work with is licensed, insured and highly reviewed by Bay Area homeowners.

How do I tell if a roofing quote is fair?

Price alone can't tell you, because two bids that look similar often cover different work. A quote is fair when it's complete, specific and from a licensed contractor, and when its price is in line with other complete bids for the same scope. Use the checker, then get at least one more written estimate.

Tick what your written bid includes.

Contractor's license number, and it shows active with a C-39 roofing classification on CSLB Workers' compensation status (or an exemption) shown on the CSLB record The roofing product named by brand and line, with its Class A rating How many existing layers come off, and disposal A unit price for replacing rotten or spaced decking, per sheet or per square foot Underlayment type New flashing at walls, chimneys, skylights and valleys, plus drip edge and pipe boots Ventilation (ridge, eave or other vents) Gutters, skylights and solar: included, excluded or priced separately Who pulls the permit and whether the fee is included Cool-roof rating, if your climate zone requires one Start date, expected duration and how the house is protected if it rains Workmanship warranty in years, and the manufacturer warranty tier A payment schedule tied to completed work Contract price on the bid (optional, dollars) Down payment the roofer asked for (optional, dollars)

Why does each line matter?

License and workers' comp: California requires a contractor's license for this work; look it up on CSLB and confirm the C-39 roofing classification.
Product and Class A listing: you should know exactly what goes on your roof, and fire hazard zones require Class A.
Layers and decking: California's code limits recovering (CRC R908), and rotten or spaced decking is the most common surprise. A unit price keeps it predictable.
Flashing and ventilation: reusing old flashing is a common shortcut.
Permit: reroofs generally need one; who pulls it should be stated.
Cool-roof rating: required on qualifying reroofs in climate zones 4 and 8 through 15, which includes the South Bay and inland Contra Costa (CEC).
Warranty and payments: workmanship years in writing, and payments tied to progress.

What are red flags in a roofing quote?

A down payment above California's legal cap (CSLB)
An offer to discount the job to cover your insurance deductible, which California generally makes unlawful (Penal Code 551)
No license number, or a license that isn't C-39
Pressure to sign the same day, or a door-to-door offer after a storm (CSLB disaster guidance)
"Labor and materials" with no product, layer or decking detail

Is my price too high?

We don't publish per-square or per-city prices, because real Bay Area bids swing with layers, decking, access and material. The reliable test is a second complete bid for the same scope. Request a free estimate below, and see what drives roof replacement cost and the roof size estimator.

Frequently asked questions

How many roofing quotes should I get?

Two or three complete written bids for the same material and scope is a common rule of thumb, and it's the best way to test price.

What is the maximum down payment for a roof in California?

California law caps the down payment on a home improvement contract; CSLB's roofing guide explains the limit.

Why is one roofing quote so much lower than the others?

Usually because it leaves something out: decking, flashing, ventilation, tear-off of a layer or the permit. Compare line by line.

Should a roof quote include the permit?

It should say who pulls the permit and whether the fee is included.
