Cal-Pac did a beautiful job repairing the roof on our Church buildings. We discovered several leaks throughout the facilities. It was during the heaviest period of our most recent rainy season. Cal-Pac managed to get us on their busy schedule. They had to assess the condition of the the roof and give us a bid. Theirs was the most reasonable for our budget and they did not disappoint. We host a Child Care Center on the property. They did a great job with little or no interruption to the Center. Over all this was an excellent experience, that was completed in a very timely manner. I would Definitely recommend them for any type of roof repair.

Earl and his team did a great job on a leaky roof that our tenants were dealing with. From the beginning Earl communicated very well, let me know cost before proceeding with the project and was very professional. I would recommend Cal-Pac roofing to anyone that has roofing needs.

Thanks Earl!

Highly recommended! After seeing that we had a leak in our ceiling/roof in the middle of the past major rain storms, they were able to come out and check our roof the same day we called! After immediately seeing the problem, they provided a quote by the next day. Since the repair could not be performed until the rain storms passed, they were able to put a tarp over the problem area to stop the leaking in the interim. They then scheduled the actual repair right after the raining stopped, and they did a great job, and no more leaking!

If I could give them 10 stars I would. Everyone I have dealt with has been terrific. The work is wonderful and they have helped me even when its not been the roof but a leaking window. Wish I could find other contractors as good as they are.

Cal PAC Roofing is an excellent contractor. I cannot say anything negative about them. From the estimator to the workers they are all polite, let you know if anything unusually comes up, always on time and they do a great clean up job at the end of the day. I got 5 bids to replace the roof on my home. Cal PAC was not the lowest and not the highest. I selected Cal PAC because I felt the communication between us was good. I asked questions and they gave me an answer. If the person I was talking to could not answer, they would check on it an get back to me.
Here's a good example. First day on the job, they start to tear the old roof off. They found one side had 2 layers and the other had 3 layers. The 2 layers was plywood and tiles, but the 3 layers was shingles and 2 layers of tiles. They took pictures so I could see what they were talking about. I couldn't explain how that happened. Now their bid was for the 2 layers, so there was going to be some additional cost. I told them to continue working and let me know ASAP what the additional cost would be. To my surprise the addition cost was much lower then I expected. I'm happy I have a new roof and I'm even more happy I picked Cal If you are ever looking for a roofing contractor call Cal PAC and mention my name, Nancy Chew.

Cal-Pac Roofing did the metal roofing for my new house in Millbrae, CA. My wife loves it. Price is not cheap but worth it.

Choosing the right roofing contractor is always time consuming, given the numerous ads and reviews on line. But I am lucky for two of my neighbors in Foster City hired Cal-Pac to do their new roofs. This saved me all the troubles to shop around as I could easily get their cost and feedback from my neighbors and was able to witness their superb performance on site. I then called Tony for an updated quote and he gave me a detailed assessment of our roofing condition and recommended the appropriate GAF composition shingle with the 25 year workmanship warranty which suit our need. When the job started, I was happy to note the same crew who did my neighbors' roofing projects showed up. After a new roof was installed on my house, I was happier to see this team did not let me down and met my expectations like my neighbors. Members like Brian, Robert etc are real roofing professional veterans. They were punctual, industrious, attentive and always emphasized on quality. Earl the installation manager was very responsible and kept me informed daily of the progress and I am grateful that he drew my attention to rotted plywood under roof which saved my future replacement need.
Thank you all in Cal-Pac for my nice new roof !

Cal-Pac did our roof in Foster City. It was a big, complicated job and they handled it professionally: showing up when they said they would, meticulously cleaning up each night, finishing when they said they would and handling a couple of issues quickly and competently. I would definitely recommend them.
