Recommended Customer Reviews

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+.

These guys are a class act. From the consultation with Tony, who clearly knows his stuff. He listened well, explained everything and also advised based on his years of expertise. Once we signed, we met Earl. He was our go-to guy for execution of the job. He too met with us, patiently explained the process and followed-up consistently throughout the job to be sure we were always on the same page. Brian was so patient and helpful...very much a detail guy. The crew? Amazing. Professional, courteous, prompt and CLEAN! This operation is a well oiled, hard working machine. Couldn't be happier and can't thank you guys enough.

Called for an estimate because my home used Cal Pac roofing before I purchased it. I constructed an addition and ask Cal Pac to come give an estimate to finish the edges of a single ply membrane system. Long story short, they didn't show up, nor they called for a follow up. Small jobs etc. forget about it, their customer service is horrible. I am sure they are great for people with larger jobs and $$$.

We had several companies come provide an estimate for a new roof, which was several years past time for the work to be done. All the estimates were similar in cost but we chose Cal-Pac Roofing because of their 25-year workmanship warranty. Most others were offering 10 years. Unfortunately, like many others apparently, we waited until just prior to an El Niño winter to do this project, so work was delayed by longer than we would have liked. The good news is that when a leak sprang up, and we had several, Tony would come out and patch the spots within a reasonable time and with a smile too. When we got a call that work would begin, we were thrilled, to say the least. Now that the job is finished, we are ecstatic! The recommendations made for material functionality and aesthetics were spot on. The work is the highest quality and looks great! The crew was pleasant and professional and they went above and beyond expectations during clean up every day, ensuring no nails or debris was left anywhere for our dogs to be hurt on. I highly recommend this company and send my sincere thanks to everyone at Cal-Pac Roofing!

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!

Tony and crew did a great job on our house. We moved into a house with an old wood shake roof and felt like the time was right to replace it with some composite shingle. Tony came over, introduced himself, hopped on the roof for some measurements, and took pictures with his phone which helped out while he explained his initial plans. I had a lot of questions and Tony took the time to explain what he was planning to do and more importantly why he chose to do it that way. There are always lots of options available and if you do your homework you'll notice that there's a lot of different ways to put on a roof. It's not just about what material and color you're going to use on the top. That's just what you see once it's done. There's a lot of stuff underneath it that's arguably more important as far as the functional performance of the roof. Sheathing material, ventilation, ridge type, flashings, and stucco work to name a few. Tony will talk you through it all.
After our initial discussion I was still a bit undecided on some of the shingle options available. Tony sent me a list of homes in the area that they had done in the past which were great examples of each option I was deciding between. Also gave addresses for each color available which made our decision really easy. The quote followed shortly after, fully itemized and clear.
Communication was always so fast and informative. I had lots of questions and must've called Tony four or five times before everything was signed and scheduled because I'd come across some new material or technique. Each time he was either immediately available or called beck within a few hours with a complete answer.
Constructions started promptly on schedule, we actually got started early due to a time slot that became available. Total time was 4 days to complete the roof. We took off on a little vacation during the construction (again the timing was just perfect) and Tony sent us photos from his phone on a daily basis to keep us up to date on how everything was looking. We really appreciated that.
Upon our return, everything looked beautiful. Our neighbors have given us compliments on our new roof and they said the noise was reasonable and commented about the cleanliness of the job.
Very impressed with the choice of materials, design decisions, and end result. Cal-Pac is not going to skimp on materials just to get the lowest bid. If you want the cheapest bid look elsewhere -- come here for quality, customer service, peace of mind, and a great warranty.

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.

Completely satisfied with CalPac Roofing....great job!
Tony was thorough in explaining all the options for us and work proceeded as scheduled. Crew was on time, courteous and cleaned up daily. Very professional job!
Being a certified Hospital Inspector for new construction and checking out the progress on my house daily, I feel I qualify to let you know that you will get your monies worth from a quality company like CalPac.
The warranties are great and transferrable...peace of mind I say.
Check them out, you won't be sorry.
