Higher than most — the typical roofer in California sits at 0.8%. A higher share is a reason to read the critical reviews below, not a verdict.

We hold no one or two-star review text for CAL-PAC ROOFING SAN MATEO. That is not the same as there being none — it means our capture did not reach any. The rating breakdown above is Google’s own count and is the number to go on.

I highly recommend CAL-PAC ROOFING SAN MATEO. I had to get a new roof ASAP due to an insurance issue. Earl from Cal Pac came over immediately and he was extremely sympathetic to our situation. He was a straight shooter and encouraged me to get other quotes. We took his advice and in the end found CAL PAC to be reasonably priced. We signed the papers and within a couple weeks we had guys up on our roof. We're not only pleased with the work that was done, but we are also happy with the transparent way that they conducted their business. We have nothing but good things to say about CAL PAC.

John and Brian and crew did a great job of installing a Decra roof for us. They answered all of my many rounds of questions, kept us informed of project status every step of the way, started and ended in timely fashion, and were a pleasure to work with. The roof is beautiful! Recommended!

Cal-Pac did a great job installing our beautiful new roof and I enjoyed working with their very experienced and professional crew. Our new roof looks great. I also appreciate that they helped us fix a leak in our old roof while waiting for the new installation. I am happy to recommend them.

John and the team at Cal-Pac Roofing did a great job installing our PV solar system. They provided sound advice on system size and panel location, took care of permitting and communication with PG&E, and showed up to do the work when they said they would. I highly recommend Cal-Pac Roofing company.

Solar and battery installation. Great service, on time and great value for the money. As a retired plumbing contractor I sometimes expect more out of other tradesmen. I got that level of service from Cal-Pac Roofing on this job. Very happy!

We interviewed multiple roofing companies before we selected Calpac and we were not disappointed. John, Earl, and the team did an initial walk through of the roof and helped us select the type of shingle and gutters. They started on the roof a few weeks later and finished it all in about 4 days. We have a section of the roof that is flat and they laid down a rubber membrane that came out really nice. They were really easy to work with and coordinated with us as we did some electrical work while the roof was off. I highly recommend Calpac for your roof!!

Cal-Pac repaired my existing solar system by installing new microinverters. They did a fantastic job. They were a pleasure to deal with and always showed up on time. I highly recommend them.

Where this page comes from
Every figure above is Google’s, captured on 24 September 2026. The star average and the 16 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 16, of which 11 have any text — and it is not everything Google shows.
Roof Warden does not verify licenses, bonds, insurance or workers’ compensation cover, and nothing on this page should be read as though we had. Confirm those directly with the contractor and with your state or provincial licensing body before you hire anyone.
