  • “These people are gold. You just can’t find people like this anymore. I think I’ve referred five or six customers to them since they completed my job. I had a small problem a year later, and they took care of it immediately. The roof is beautiful, and the product is awesome. They put in two sky tunnels, too. Those really are terrific. I put one in the central hallway, and it just opened up the whole house. At night, even the moonlight lights up the house.”

  • “We went with the Decra system, and we’re really happy with it. It’s so nice looking, and I’m just delighted that this will be the last roof I ever have to put on. Cal-Pac Roofing did what they said they would do, and finished the project ahead of schedule. I heartily recommend them.”

  • “They’re very good. I would recommend them absolutely. The re-roofed a commercial property I own in San Mateo, and did a great job. Their reputation is great, and they’re very good people.”

When you want the best roof money can buy, call Cal-Pac Roofing. “We are the exclusive distributors and installers of the Decra Roof system, which is simply the best roofing system available,” explains John Rossi, District Manager of Cal-Pac Roofing in San Mateo.

Used in over 80 countries, the Decra System combines a durable, lightweight steel core with specially bonded earthstone granules. This system offers unsurpassed protection against water, fire, wind, and earthquakes, and comes with an amazing 50-year, transferrable warranty.

Cal-Pac Roofing has completed over 10,000 roofs in San Mateo County over the past 25 years.

“Our primary business is new roofing and roof replacement,” John explains. “As well as Decra roofs, we do traditional composition shingles. We also do pitched and flat roofing, using a special polyvinyl thermal plastic membrane which is mechanically fastened to your home.

“It’s a completely wateproof sytem – the ultimate solution for flat roof problems. Because no tar is involved, it’s also completely odorless process. You can stay in your home while we’re doing the work.”

Cal-Pac also installs Sky Tunnel skylights. These patented, flexible reflective tubes can be bent around rafters and other obstructions to bring light anywhere into your home.

“We can install these skylights in two hours because we don’t have to build a light well,” John explains. “That means they cost a fraction of a traditional skylight.”

“We’re a local company, and we have an excellent rapport with all the local building departments and inspectors. If you’re looking for a roofing contractor, call your local building official and check us out with them.”

“Our customers like that we’re very easy to deal with. Our crews are accessible, they answer questions, and cover all areas of concern. Our installation managers are on every job every day. We are there for the client every step of the way.”
