How do I know if a San Diego roofer is legitimate?

Verify the contractor's CSLB license at cslb.ca.gov and confirm it has a C-39 roofing classification. Check that their certificate of insurance is current by calling the insurance carrier directly, not the contractor. Confirm they've been in business for at least five years (96% of roofing companies fail within five years per the BBB). Look for a manufacturer certification like Owens Corning Platinum Preferred, which requires ongoing training, financial stability, and warranty backing.

What are the most common roofing scams in San Diego?

The four most common roofing scams in San Diego are: door knockers offering a free inspection who then claim to find storm damage, storm chasers in unmarked trucks who follow weather events and disappear after collecting deposits, high-pressure closers who demand a same-day signature with a today-only discount, and cash-only deals that knock $2,000 off in exchange for skipping permits, insurance verification, and warranties.

What does a roof actually cost in San Diego in 2026?

Honest 2026 San Diego pricing ranges by material: asphalt shingle replacements typically run $12,000 to $22,000 for an average single-family home; concrete or clay tile re-roofs run $25,000 to $50,000; flat (TPO or modified bitumen) roofs run $14,000 to $28,000; and standing-seam metal roofs run $30,000 to $60,000. Prices vary by square footage, slope, layers being torn off, ventilation upgrades, and underlayment specs.

How many roofing warranties should a contract include?

A complete roofing warranty package has three layers: the manufacturer's product warranty on the materials, the contractor's workmanship warranty on the installation, and a system warranty issued by the manufacturer that covers materials and install together (typically only available through certified contractors like Owens Corning Platinum Preferred). Two of the three are nearly worthless without the third.

Should I get a roof inspection before buying a home in San Diego?

Yes. A general home inspector typically spends 10 to 15 minutes on the roof and is not certified to assess remaining service life, ventilation, flashing, or underlayment. A dedicated roof inspection from a licensed roofing contractor is free at most reputable roofers, takes about 45 minutes, and produces a written report with photos.

Does my roof need to be evaluated before I install solar?

Yes, every time. Solar panels typically last 25 to 30 years. If your roof has fewer than 15 to 20 years of service life remaining, you will pay to remove and reinstall the panels mid-life, which can cost $3,000 to $7,000. The right time to combine roof and solar is when the roof has under 5 years of life remaining or is already being replaced.

The roofer you sign with today probably won’t be around to honor a warranty in 2031. The lifetime warranty on the brochure is only as good as the company behind it. Roofing Red Flags shows you exactly how to tell which contractors will still be here in ten years — and which ones are about to disappear with your deposit.

Dana showed up on time and got right to it. Speaking to Dana afterwards it was obvious to me that he’s an expert when it comes to roofs and all they entail. Dana’s repair team showed up on time and made all the identified repairs needed timely. Would definitely use Dana Logsdon Roofing again.

We had multiple quotes and estimates from different companies for skylights. But I went back to this company because they did my roof and fixed my roof in the past. Worked fast and great work. Was honest when they broke a few roof tiles and replaced right away.

The experience has been great from beginning to end. I want to thank John, Jose and the roofing/tiling team for the fix. They were so nice and professional, and I appreciate the updates and communication during the multi-day job. Devan reached out during the fix and visited after the completion to check on my experience.

Willie came out and quoted me for a roof repair that was long overdue. Ramon came out and went above and beyond replacing shingles and making the repair blend in with a 10-plus year old roof. They were respectful of my property, and I now have a roof that no longer leaks. I would absolutely call them when I need a new roof in a few more years.

From the founder

Why we wrote this guide.

I’m Dana Logsdon. My family has been roofing San Diego homes for four generations. Long enough to see every scam in the book, and long enough to know that an informed homeowner is the best customer a good contractor can have.

This guide is the same advice I’d give my own neighbor. Read it before you take a single estimate. It will save you money, stress, and possibly your house.
