To start with NEMA Roofing, call [866-631-3366](tel:866-631-3366). Each check takes minutes and uses public records or a phone call. Together they separate a company that fixes the cause of a leak from one that seals over it and leaves. ## How to read the state license record California requires a contractor’s license number on every ad, business card, bid and contract, and the Contractors State License Board (CSLB) warns that seeing a number does not mean the license is valid. Look the company up on the CSLB “Check a License” page by number or business name and read the whole record: - **Status:** it should say the license is current and active. - **Classification:** C-39 is the roofing classification. A B (general building) license alone is a different trade. - **Workers’ compensation:** CSLB requires every active C-39 roofing contractor to carry it, with or without employees. An exemption on a roofer’s record is a question to ask. - **Disciplinary history and complaint disclosure:** read what was filed and whether it is resolved. One resolved item over years of work tells you less than a pattern of open ones. - **Business name and address of record:** they should match the company on the estimate.

Read the reviews for these details instead: - **Repair jobs, not only new roofs.** Search a profile’s reviews for “leak”, “repair”, “flashing” or your roof type. - **What happened after the first rain.** A review written the day the crew left cannot tell you whether the repair held; later updates can. - **How problems were handled.** Read the negative reviews and the company’s replies. A reply that explains what was done to make it right is a better sign than a perfect score. - **Where the rating comes from.** A badge on a company’s own site is not a review profile. Open the profile itself (Google, Yelp or the Better Business Bureau) and check the count and dates there. - **Recent and spread out.** Reviews across several years show steady work; a burst in one month says less. ## Confirm certifications at the source Manufacturer programs (for example GAF, Owens Corning and Polyglass) list their certified contractors in public directories on the manufacturer’s own website. If a company says it holds a manufacturer credential, find it there under the same business name. The credential matters on a repair because matching materials, flashing details and any registered manufacturer warranty on the existing roof depend on work being done the way that manufacturer specifies. A logo on a truck or a website is a claim. The manufacturer’s directory is the record. ## Ask for references that match your roof A reference is only useful if the job resembles yours. Ask for one or two recent repairs on the same roof type (tile, shingle, metal or flat) and, if possible, the same problem. Then ask the reference: 1. Did the company explain what caused the leak before quoting? 2. Did the final invoice match the written estimate, and were changes agreed in writing first? 3. Has the repair held through the rainy season since? 4. Was the site left clean, with no nails or debris in the yard? 5. If something went wrong, how fast and how well did they respond? ## What the inspection visit tells you The best test of a repair company is the first visit. A company that does quality repairs: - checks the ceiling stain and the attic before pointing at the roof, because water often enters well uphill of where it shows; - shows photos of the damage and explains the cause in plain words; - writes a scope that names the fix (for example “replace step flashing at the chimney” rather than “seal leak”) and the materials; - tells you when a repair is not worth doing because the roof is near the end of its life. Be wary of a price given over the phone without anyone looking at the roof, pressure to sign the same day, or a scope that relies on sealant alone.

The answer should be the contractor, not you. - **Which manufacturer warranty will be registered?** The top manufacturer warranties, such as the GAF Golden Pledge or the Owens Corning Preferred Protection warranty, can only be registered by contractors that manufacturer has certified; ask which one applies and ask for the registration after the job. - **How does the new roof meet current code?** Replacing more than half a roof triggers the state energy code’s cool-roof rules in many climate zones and fire-rating rules for the whole roof covering; the contractor should say how the chosen product complies.
