How to vet a roofer and dodge the storm-chasers

Roofing draws more fly-by-night operators than almost any trade, because the work is high-dollar, the homeowner usually cannot inspect it, and a fresh roof looks fine for a year whether it was done right or not. The storm-chasers know all of this. Here is how to vet a roofer so you are hiring someone who will still be around when you need the warranty.

Check the license

In California, roofing requires a C-39 roofing contractor license. Look up the number on the state licensing board site and confirm it is active and in the company's name. Confirm they carry workers compensation, because roofing is dangerous work and an uninsured fall on your property can become your liability. Confirm general liability too. A legitimate roofer gives you these numbers up front. If a salesman at your door cannot produce a California license number on the spot, the conversation is over.

Look for manufacturer certification

Major roofing manufacturers certify contractors who install their products to spec. That certification matters for two reasons. First, it usually means a stronger warranty, sometimes a long workmanship and material warranty backed by the manufacturer, not just the contractor. Second, that warranty only holds if the installer is certified and follows the spec, so a certified installer is one who actually knows the system they are putting on your house. Ask what they are certified to install and what warranty that buys you, then get the warranty terms in writing, not as a verbal promise.

Beware the storm-chasers

After a hailstorm or a windstorm, crews from out of the area show up knocking on doors, offering to handle your insurance claim, asking for a signature on the spot. Some are fine. Many are not. The pattern to watch for is an out-of-town address, high-pressure door-to-door sales, a push to sign before you have read anything, and an offer to waive or eat your deductible, which is insurance fraud and can void your claim. A roofer who will still be in town to honor a warranty in five years does not need to chase storms across state lines.

Hire local and recent

A local roofer with a real address and recent jobs in your area is worth more than a slick pitch. Ask for a few roofs they finished in the last year and go look, or talk to those owners. Ask how they handled the tear-off, whether they found rotten decking, and how the final number compared to the bid. Local reputation is hard to fake and easy to check, and a roofer who has been working your neighborhood for years has a name to protect.

Get the inspection and the bid in writing

Before any work, a real roofer inspects the roof and shows you what they found, ideally with photos of the actual damage, not a generic claim that the whole roof needs replacing. Be careful with anyone who finds catastrophic damage on a roof that looks fine and is suspiciously eager to get on the phone with your insurance. Get the scope, the material, the warranty, and the payment schedule in writing before you sign, and never sign a contract that authorizes work contingent on an insurance payout without understanding exactly what you are committing to if the claim comes back smaller than promised. The roofers worth hiring are patient with these questions. The ones in a hurry to get a signature are the ones to send away.

Red flags that should stop you

• Door-to-door pressure after a storm, especially from an out-of-area company.
• An offer to cover or waive your insurance deductible.
• A demand for full payment up front, above the legal down-payment cap.
• No license number, or one that does not check out.
• Damage found on a roof that looks fine, paired with a rush to call your insurer.
• No manufacturer certification and a warranty backed only by a company that may not be around.

To know whether a bid is even in the right range, read the roof replacement cost guide first. The general checklist in questions to ask before you sign applies to roofing too. More on how the trade is set up is on the roofing page.

One reason we put outcomes on Quotrr that cannot be quietly deleted is exactly this trust gap. A roofer with a real, verifiable track record has nothing to hide. You can read how that works on the Quotrr Score page. Hire on a record you can check, not a knock at the door.
