What San Diego Homeowners Say About Mercer Roofing Co San Diego
Reviews matter in roofing because the work is hidden until it fails. In San Diego, where every neighborhood from Rancho Bernardo to Chula Vista deals with salt air, Santa Ana winds, and occasional monsoon-season cloudbursts, a roof’s performance is tested constantly. Homeowners tell us the same thing: they want the crew who shows up looking like professionals and writes down the price before touching a shingle. That combination is what earns us the kind of feedback below. Here’s what your neighbors around San Diego have said about working with Mercer Roofing Co San Diego.

We had water staining on the ceiling in our Clairemont home and called Mercer Roofing Co San Diego expecting bad news. Grant’s technician found the flashing around the chimney had pulled loose and was channeling rainwater straight into the decking. He replaced the flashing, resealed the penetration, and showed me photos of the fix before he came down off the ladder. The written guarantee on the repair was handed to me before I signed anything.

Our entire roof in Scripps Ranch was past its useful life, and we’d put off replacement for two years because we dreaded the sales pitch. Mercer sent a written price with the scope broken out line by line, GAF shingles included. The crew removed two layers of old material, replaced three sheets of rotted decking they found underneath, and the final invoice matched the original quote to the dollar. That never happens in this trade.

I’m a retired contractor, so I watch tradespeople carefully, and the Mercer crew in North Park earned my respect. Every person who came to the door was in a clean uniform with a photo ID badge, and I received the technician’s name and photo by text before he arrived. They re-flashed two dormer valleys and replaced damaged underlayment without making a single cut in the wrong place. The 365-Day Done Right Promise isn’t marketing language; it’s written on the paperwork.

We had a shingle blow-off during a Santa Ana wind event in La Mesa, and the exposed area started letting moisture into the attic within days. I called on a Sunday evening and a live person answered the phone, which honestly surprised me. Mercer’s repair tech came out, matched the shingle color to our existing CertainTeed roof, and sealed the perimeter. He also checked the rest of the roof for wind-lifted shingles and re-sealed two more he found.

The concrete tile roof on our Point Loma house is original to the 1990s, and we’d been nursing it with patchwork fixes from whoever was cheapest. Mercer Roofing Co San Diego was the first company that gave us a straight answer: repair the failing sections now, plan for full replacement within two to three years, and here’s exactly what both cost. They repaired the worst valley and replaced all the metal flashing. The written price was in my hand before any work started, and no one pushed me toward a replacement I didn’t need yet.

I manage a small commercial building in Kearny Mesa, and roof leaks there become tenant problems fast. Mercer’s crew diagnosed a failed HVAC curb that was allowing water to pool and penetrate the membrane. The technician who came out was background-checked and identity-verified, which matters to me because I hand over keys and roof access. They installed new curb flashing, sealed the membrane, and followed up with a written guarantee on the repair. If it fails within a year, they return free – that’s the part that convinced me to stop calling around.
