Arrived when he said he would. Gave me a very reasonable quote compared to two other quotes that I received. Fully explained everything that would need to be done.

I used Cal-Pac in the pas for my roof and just used them now for solar panel an battery installation. They did a great job sizing what would work on my house, installing it on my roof, and subcontracting the electrical work. The inspector had ZERO issues with the install and was approved the first time. This is not to be underestimated as cities can be hard to deal with

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.

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.

Cal-Pac Roofing has provided roof installations on a number of my projects over the last twenty years and our experience has always been positive. The general manager sees that roof integrations are well planned and executed. Cal-Pac maintains a well-trained and competent workforce who genuinly care about the quality of their work and the lasting impression their jobs will have on property owners. I have no hesitation working with them in the future.

I highly recommend CalPac Roofing in San Mateo. Tony, right from the beginning, was very thorough and patient in helping me choose the correct roofing material. Once the job started, Earl, the supervisor, kept me completely informed of what was happening each day. The crew was hard working, efficient and cleaned up every day! They were all professional and a pleasure to deal with, including the owner John.

I would not use them for a replacement roof, gutters, or downspouts. I will not let them on my property. They forgot who the customer is. NOW, WAS. The service received. NONE! Just false promises. They put the downspout trust into one man. Earl. He was too aloof for me. I have been in contact with this company since at least 23 January, 2018. Today it is 6 April, 2018.

My downspouts are still not done. We figured out a price, but waiting for them to put the estimate into a written estimate was an act of congress. I received one estimate, but without details. I replied in an email what we spoke about. Three weeks later, details placed onto the email estimate. We finally had a meeting of the minds. And four months later, I am still waiting for my downspouts replaced.

We had a tentative date of mid March. No contact about a follow up date. I have had more patience than I should have. NO more. I am tired of waiting. Their non responsiveness to issues with health of my home speaks volumes. I am thankful it has been dry, but this is now past my patience. When I need a new roof, CAL Pac will not be called. They did a roof for me before, on my current property.

They are no longer welcome here. I would have thought they would have done the work earlier since both are located in San Mateo local, and my standing as a prior customer. Wow, to turn away work. Such independence. May their business thrive. If I have anything to do with it. RUN! I will not permit someone who does not think my house is worthy of their time. They have been replaced by someone who really wants to do the job!

We have only great things to say about Cal-Pac. The entire process from estimate to job completion was extremely smooth and our roof looks great. In addition to the great work, there were a few things that really stood out about Cal-Pac for us: (1) their timely communication, and (2) they really care about the quality of their work. Throughout the entire process, Tony (our sales person) and Earl (our project manager) kept us informed about what was going on. Anytime we had questions we received answers extremely quickly.

Prior to installing the new roof, we also had an area that was leaking during the rainy season. Tony came out and patched the area for us to avoid any damage to our home while we were waiting for the weather to clear and have the roof installed. Earl and team then did our install. They showed up timely every day during the install and made sure the area was clean when they left each evening.

We were also planning on replacing pool solar on our roof once the new roof was installed and were extremely concerned about roof penetration from the solar (our prior solar install caused a lot of issues with our roof). To avoid any future issues, Earl coordinated with our solar company to ensure that the solar was put on the roof with no penetrations. He even came out and reinspected the roof after the solar was on to make sure it met his requirements. In short, Tony, Earl and Cal-Pac are A+.

I'll start my review by stating that we didn't have any actual work done by this company - so this review is not based on workmanship. How could we have had any work done? The customer service we received was terrible. Things started off ok with a timely response to an inquiry for a quote to replace our roof. A few days later, we had Brian come out.

We chatted for a short time, discussed options. Surprisingly he didn't come prepared to actually get ON the roof or inspect it. Ok, he promised to show up the following Monday with several people to inspect the roof. Ok. I stayed home - waited for a call, and email, or even anyone to show up. Nope! Never heard from them again!

Cal Pac Roofing did a great job on my new roof and custom gutters. We has lots of dry rot issues and they resolved that problem and made all of the necessary repairs to the stucco exterior to make it look like there was never an issue. Their pricing is competitive and I would use them again.

To sum it up, it was a job well done! Good quality materials and good workmanship. Cal Pac just made the whole process so simple and smooth - from beginning to end. The big storm that hit the bay area in December 2014 apparently hurt a lot of homes and so roofing companies were in high demand. We found it so difficult to get an estimator come out to assess our roof and provide a quotation.

Of the 4 roofing companies we called, Cal Pac responded so quickly and set a date to assess our roof. Tony (from Cal Pac) came by and on that same visit, gave us a quotation. We were impressed and signed the next day. Soon after, the other 3 roofing companies came over and gave us lower bids. We still went with Cal Pac because they offered the 25 year Golden Pledge warranty while the others offered 10-15 years. Tony was thorough, obviously knew was he was talking about, and he gave different suggestions on what we could do with the roof, he was brief and just cut thru the chase.

He gave us examples of roofs they had done, which was very helpful as it was hard to visualize the roof type/color from a brochure. He was always accessible and went above and beyond by providing us guidance and suggestions in our "semi-roof-related" questions that was not part of their scope of work. We also have to mention that the office staff was also very professional and friendly and the entire crew was very polite and just quietly worked about their way. We would most certainly recommend CalPac to any of our family and friends needing roof replacement in the future!

We've had our share of the usual horror stories with workmen in the construction field, so we put off contacting a roofer for a year. Finally, with the rainy season looming, and the flashing on our 20+ year old roof in visibly bad shape, even from the ground, I went on Yelp to begin what I thought would be a long, excruciating process. I figured, with all the great reviews, Cal Pac would be a good place to start. Turns out that we felt so good about Tony and the way he answered all our questions, that we signed the contract the day he came over to the Coast to evaluate our roof.

He was able to give us a start date for the project that fit our schedule. Tony remained accessible to our calls throughout the project. The office staff was helpful as well when we had questions. The guys who came to do the actual work were polite, on time, neat looking, diligent, and worked in a timely, but unhurried manner. Brian, the on-site boss, oversaw the details. Earl came by to take photos and check on how the work was going. There was a scrupulous clean up every day. Our two story house had a beautiful new roof in three days. We are happy we went with Cal Pac Roofing.

The estimate was quickly scheduled (unlike other companies that made me wait for over a week or two) and Brian was friendly and informative. He went up on the roof to take a look and wrote up a prelim estimate for the job. A lot of other estimators didn't even bother going up on the roof to inspect it. Cal Pac was one of the more competitively priced bids and they were GAF Master certified with the lifetime warranty, so I went with them.

The job started ahead of the scheduled time frame they first gave me, so that was a good surprise. The job started on a Tuesday and ended four days later. As far as I could see, the work was done quickly and efficiently using the correct materials. Two issues made me take off a star: 1. The job site wasn't cleaned up as well as I would have liked, especially after the first day of during the roof tear off.

I found lots of old shingle pieces and pieces of wood shards around the back and front of the house. I also found quite a few nails as well (three nails on the driveway which would have been bad for my wife's car when she came home). I think they probably just cleaned the house 2-3 feet around the house and didn't really inspect the rest of the lot. 2.

After the job was finished on that Friday, I didn't hear from them the entire next week. The final inspection wasn't complete and they still had their sign out front on my yard. After the week of not hearing from them, I called to see what was up and they quickly scheduled the final inspection a few days later. They basically got free advertising from my house and I wonder if that would have been the case indefinitely unless I called them. Despite the down marks, I would still use them for a roofing job as I believe their work was solid and their price was much better than most of the competition.

We've been dreading dealing with our roof situation as we had 2 layers of roofing and knew that there was some damaged wood on the eaves and rafters. We called 4 roofing companies, all based on BBB and Yelp reviews and chose Cal-Pac Roofing after sitting down with Tony, the estimator, and having all of the optioins explained to us. Along with showing us pictures of the problem areas and his recommendations for solving them, he went over all of the roofing choices available to us, as well as realistic life spans and warranty options.

We chose a GAF composition shingle since we were very impressed with the 25 year workmanship warranty that Cal-Pac is authorized to provide since they're a Master Elite GAF Contractor. One of the other roofing companies we called also offered this warranty but didn't really explain what was involved in the construction process to get the warranty or how they were going to handle the damaged areas so we just felt more comfortable with Cal-Pac.

They did the work just as described, Tony sent us pictures each day of the progress and the roof looks great. The best part is that we now have one more item crossed off our list of things to deal with on this old house.

Tony and his team did it again. They re-roofed our office building in record time and with such ease. Again.we encountered a problem.5 months later. They came out and it turns out it wasn't their problem at all but rather our HVAC team. This time we use the Duralast product for the flat roof. We've gone from having buckets in nearly every office to nothing. So exciting to have a dry office this winter. These guys are professional and fast. Every time we can recommend them we will.

So my roof had a leak. Eh no biggie! Come on, it's the Bay Area! But when my closet started getting flooded, and my faux fur coat had been damaged by the water, it was time to do something. My best friend Bertie actually lives right on the other side of El Camino from this place, and I've always seen it in all my years of growing up on the hell known as the peninsula.

So I decided to dig deeper. Looked them up; Better Business Bureau. Good sign, but we were still going to get three estimates from three different companies, as recommended. We scheduled three estimates. Of the three, Cal-Pac was the only one that ACTUALLY GOT ON THE ROOF. Wow! What a concept? Actually get up on he roof and inspect it before giving us an estimate of the cost?

What kind of strange business tactic is that? And Brian, our estimator, ACTUALLY DISCUSSED THE DETAILS OF THE PROBLEM. Again, another bizarre occurrence! Cal-Pac's estimate was a little bit more than the other two guys, but because of them ACTUALLY EXPLAINING it in a professional manner, we felt that we could ACTUALLY TRUST that what was wrong wasn't just bullshit like the other two hokey guys, and that it would ACTUALLY GET DONE CORRECTLY. Brian explained in depth our different options, and roofs are kind of an important investment, so you really ACTUALLY APPRECIATE when someone doesn't just blow over all the details. Needless to say, we went with Cal-Pac.

The installation guys were all really courteous and the whole thing was ACTUALLY PAINLESS. So, most people don't need a whole new roof everyday, but it is definitely good to keep in mind when you need it. I would highly recommend them for making this as easy as possible, because it could have been a giant pain in the ass. Actually.
