Anyone can rank for “roofer near me.” Far fewer can show you a live state licence, proof of workers’ comp, and a manufacturer certification you can verify yourself in about five minutes. Here is exactly what to check — and where to look it up.
Search results rank roofers by marketing, not by licence status — so treat the list as a starting point and verify each name yourself. In California every roofing contractor must hold an active licence from the Contractors State License Board, and roofing specifically requires the C-39 classification. The CSLB's lookup is free and public: enter the company name or licence number and you will see whether the licence is active, whether the bond is in place, whether workers’ compensation is on file, and whether there is any disciplinary history. A contractor who cannot give you a licence number on request has answered the question.
Correct classification for roofing — C-39, not a general B licence alone
Written contract required in CA — for home improvement work over $500
Down payment capped by state law — 10% or $1,000, whichever is less
Our licence, to check right now — CA #1090028 (C-39)
Every one of these is verifiable before you commit a dollar. Run them on us and on whoever else you are considering — a good roofer will not flinch.
Look the company up by name or number. Confirm the licence is active, carries the C-39 roofing classification, and shows no suspensions. An expired or misclassified licence can void your homeowner's insurance claim on the work.
This one protects you. If an uninsured crew member is injured on your roof, liability can land on the homeowner. The CSLB record shows whether comp coverage is current or whether the contractor filed an exemption.
The long transferable warranties are issued by the shingle manufacturer, not the roofer — and only certified installers can register them. We are Owens Corning Platinum Preferred, which is what makes the 50-year transferable coverage available at all.
Tear-off layers, underlayment type, ventilation work, flashing, disposal, permit fees. California requires a written contract above $500. Vague one-line bids are how change orders appear later.
Bay Area jurisdictions differ. A roofer who works your city daily knows whether your job triggers a Title 24 cool-roof requirement, what the inspector will look for, and how long the permit actually takes.
A perfect score on a single site says less than a consistent one everywhere. We hold 4.6★ across 600+ verified reviews spanning Google, Yelp and the BBB, where we are A+ accredited.
Price is only comparable when the scope is. Two bids on the same house can differ by many thousands because one includes a full tear-off to the deck, new underlayment and corrected ventilation, while the other is an overlay on top of the existing layer. Ask every bidder the same three questions: how many existing layers come off, what underlayment goes down, and is the ventilation being brought to code. Then the numbers mean something.
| What you are comparing | Why bids diverge | Dig deeper |
|---|---|---|
| Repair vs. full replacement | A repair can be the right answer well past the halfway point of a roof's life — or a waste of money on a roof with two years left. | Repair or replace? |
| Material choice | Asphalt, tile, metal and synthetic slate differ in installed cost, weight, lifespan and whether your framing can carry them. | Compare materials |
| Tear-off layers | Each existing layer removed adds labour and disposal. Overlays cost less now and usually cost more later. | Roof replacement |
| Ventilation and flashing | Frequently excluded from cheap bids, and the most common reason a new roof fails early. | Roof ventilation |
“Near me” usually means something more specific. Pick the service, the material or the city and go straight to the detail.
Storm season brings crews through the Bay Area who are not from the Bay Area. These are the patterns worth refusing outright.
California caps the down payment on home improvement work at 10% of the contract or $1,000, whichever is less. A demand for half the job in advance is not a negotiating position — it is outside the law.
“This price is only good if you sign now” exists to stop you making the licence check. A roof is a 20-to-50-year decision; any legitimate bid survives a night's sleep.
Ask where the business operates from and who pulls the permit. Out-of-area crews leave, and a warranty from a company with no local presence is difficult to enforce when you need it in year seven.
A written contract is required by state law above $500. No paperwork means no scope to hold anyone to, and no record if the work has to be corrected.
On an insurance job this is presented as a favour. It is insurance fraud in California, and the homeowner is a party to it.
Usually it is a different scope, not a better price — an overlay instead of a tear-off, or ventilation and flashing quietly excluded. Compare line by line before comparing totals.
The Bay Area is not one roofing climate, and it is not one permitting jurisdiction. A roof in Santa Cruz takes coastal moisture and salt air. The same roof in Gilroy takes sustained summer heat. Sunnyvale, San Jose and unincorporated county parcels each run their own permit process with their own inspection expectations. And California's Title 24 energy standards can require a cool-roof product on a replacement depending on climate zone, slope and assembly — a requirement that surprises homeowners when an inspector raises it after the fact.
Ventilation sized for an inland attic behaves differently near the coast, where the problem shifts from heat to trapped moisture. Getting the intake-to-exhaust balance wrong shortens the life of an otherwise sound roof.
Timelines, fees and what triggers an inspection vary city to city. A roofer working your city weekly knows the sequence; one passing through is learning it on your job.
Family-owned, Bay Area based, and licensed in California since day one — not a franchise and not a storm-chasing crew.
Use the free CSLB licence lookup. Search by company name or licence number and confirm three things: the licence is active, it carries the C-39 roofing classification, and the bond and workers' compensation records are current. The same record shows any disciplinary history. Ours is CA #1090028.
Three is the usual advice and it holds up — but only if all three price the same scope. Give each contractor identical information and ask each one how many layers are being removed, what underlayment is specified, and whether ventilation is being corrected. Bids that differ wildly almost always differ in scope rather than in margin.
For home improvement contracts the down payment is capped at 10% of the contract price or $1,000, whichever is less. Progress payments after that must track work actually completed. A request for a large advance deposit is a reason to stop.
Not automatically — but check what the number buys before treating it as a saving. The most common reasons a low bid is low are an overlay instead of a full tear-off, thinner or omitted underlayment, and ventilation and flashing left out. Any of those shortens the roof's life, and the last one voids most manufacturer warranties.
Yes. A residential re-roof requires a permit in every Bay Area jurisdiction we work in, and the inspection is part of the process. Depending on climate zone, slope and assembly, Title 24 may also require a cool-roof product. Your contractor should pull the permit — if they ask you to pull it as the owner-builder, that shifts the liability onto you.
