What Thousand Oaks Homeowners Say About Mercer Roofing Co Thousand Oaks
Reviews matter because a roof is one of the only purchases you make that has to work for decades without you thinking about it. We earn ours the slow way: a written price before work starts, a technician who badges in at the door, and a 365-Day Done Right Promise that means exactly what it says. Here’s what homeowners across Thousand Oaks have told us after the truck pulled away.
Recent Reviews
“We’d been chasing a leak near the chimney for two years. Two other companies caulked it and called it fixed. Mercer’s tech got into the attic, found the flashing had pulled away from the masonry, and showed me photos before quoting the repair. They replaced the step flashing, re-seated the counter flashing, and it’s been dry through three winter rains now.”
Hector R., Newbury Park
“The written price was the reason I called. I’d had a roofer give me a verbal estimate once and then find ‘unexpected decking rot’ that doubled the bill. Mercer walked the roof, checked the plywood from the attic side, and handed me a number that did not move one dollar. No change orders, no surprises. That’s how it should work.”
Gilbert H., Thousand Oaks
“The technician sent me a text before arrival with his name and photo, then showed up in a clean uniform and actually held up his badge at the door like he said he would. I didn’t have to ask. When there’s a stranger going up a ladder onto your roof, that matters more than I can put in words.”
Elena M., Thousand Oaks
“My ridge cap shingles had lifted during a Santa Ana wind event in October. Mercer replaced them with CertainTeed shingles that matched the existing roof color closely enough that my neighbor asked if I’d had the whole roof done. The repair guarantee was in writing when they left. No fine print.”
Oscar R., Westlake Village
“After a heavy winter, the gutter apron along the back eave had pulled loose and water was getting behind the fascia board. I called on a Sunday morning expecting a voicemail. A real human answered on the second ring. They scheduled the inspection that week and the written quote listed exactly what needed replacing. The repair took half a day.”
Hector R., Thousand Oaks
“We bought a 1970s ranch in the Conejo Valley that still had its original roof. Mercer bid a full tear-off and re-roof with Owens Corning Duration shingles, new underlayment, and new pipe boots. The crew kept the yard clean enough you’d barely know they’d been there, and the project foreman walked me through the final inspection before asking for the final payment. That’s old-school professionalism.”
Gilbert H., Newbury Park
Why Customers Trust Us
Every review above points to the same few things, and those things are deliberate. A written price before any work starts means nobody gets surprised when the invoice arrives. The 365-Day Done Right Promise means if the work is not right within a year, we make it right, and every repair includes a free second visit if it fails. Technicians arrive under the Threshold Verified standard: background-checked, identity-verified, photo ID badge at the door, uniform clean and marked. Grant Whitlock holds his Thousand Oaks crew to that standard on every single visit because it’s the only way to run a roofing company and sleep at night. We work with shingle brands homeowners already trust, including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and every repair gets a written guarantee, no conditional language. If you’re pricing a roof repair or full replacement in Thousand Oaks, call (805) 309-3314. A live person answers, and you’ll get the same written-price commitment these homeowners did.
