John and Chilo were great to work with. Our house needed a new flat roof as well as tile roof. We were happy with not only Alta-Cal's price but also how they were going to do the roof. We are now ready for winter! :) I highly recommend Alta-Cal.

My nice new blue shingles!

John and his team did a great job on my roof. I got 4 estimates before going with Alta. We were able to negotiate the right price. John was very responsive. He answered all my questions and concerns. His company was also the only company that could get the certain color shingle I wanted. He even recommended an owl to hopefully deter the seagulls from pecking on the roof. He even bought the owl for me and had his worker install it! On the day of the job, he texted me to let me know the crew was there. They are fast workers, and left the home and surroundings spotless! I really enjoyed working with them. Thank you for my new roof. Hope to work with you again someday.

Alta-Cal Roofing Owner John Roach is my hero! I discovered a tile had fallen from the south-side of my roof edge and John was able to come out and replace it the same day. Mind you, this was just before our latest mini-atmospheric-river rain storm hit that evening! What a relief! John also provided a roof inspection and a quote for additional repairs the next day. Thank you for your excellent service John Roach.

Hollister Roofing - Re-Roof with composition shingles

In need of a complete tear-off and reroof I called around and got danced around by several…read morecontractors. I'd done my research, calling distributors, getting specification, etc. So the BS Meter was active, if you know what I mean. Barry came out and was straight forward and seemed legit. Glad I signed a contract with him. Was very happy with his performance and the way he left the jobsite. That resulted in several other small jobs. What more could I ask for? This was the 3rd roofing project I've lived through, and it was the most trouble-free.

Hollister Roofing replaced my roof approximately nine years ago. Recently, I noticed staining on…read moreplywood visible from inside my garage and contacted Barry, the owner, about possible moisture damage. On October 13, I emailed photographs and explained my concerns. Barry responded that the issue was condensation caused by something I had added inside and that I needed to remove it. I hadn't added anything, so I called for clarification. During our phone conversation, I felt Barry was rude and dismissive. He repeatedly spoke over me while I tried to explain the situation. He eventually acknowledged that he had confused me with another customer, and we scheduled an inspection. During his visit, Barry inspected the exterior of the roof but did not physically examine the stained plywood from inside my garage, which was the specific area I had asked him to investigate. I subsequently received an estimate for approximately $2,900 in roof repairs without what I considered an adequate explanation of the suspected cause of the damage or why the proposed work was necessary. On October 15, we sent a detailed follow-up email asking about the inspection findings, proposed repairs, warranty coverage, solar panels, and costs. We received no response, so I followed up on October 23 after seeing Barry's response to my Yelp review. Barry replied that he had not received the earlier email. However, rather than addressing the questions in the email conversation, he wrote, "And after your beautiful review, I guess we're a little past that by now." After posting my review, Barry also sent me text messages and a draft lawsuit demanding $35,000 in damages unless I removed my reviews. My disappointment is primarily with the communication, the failure to physically examine the area I reported, and how my concerns were handled. This review reflects my personal experience and opinion. Based on that experience, I would not recommend this company.

Jesse is awesome, hands down great to work with. Great communicator, great pricing, and great work!…read moreI had a small roofing job which he was able to get done in two days! We had a small addition that needed to be roofed and gutters installed. Jesse was able to come out review everything, provide a quote within hours. He got the job done two days after that! It was incredible! With the Spanish tiles we had purchased from a local vintage tile supplier, Jesse was able to have the tiles fit our roof just right, and he got it to match the rest of our house perfectly!

The good: Quick response, easy scheduling, great communication, fair pricing, excellent…read morefollow-through and service. The great: Jesse is a pleasure to work with! From the initial phone call to the gutter cleaning, Jesse and his team were on time, efficient, and thorough. While he was up on the roof, Jesse showed us where he found a few cracked tiles and explained that they weren't posing any issues yet, but we should get them repaired/replaced at some point. Since we had extra tiles lying around, he came back the following week to work on the roof. Additionally, when we asked if there was anything we could do about a few of our gutters being extra loud during the rain, he offered to come back to install some sponges that might dampen the sound of the rain hitting the gutters without blocking water flow. We decided to try his solution, and after a few days of rain, so far so good! I highly recommend Jesse and his team for any of your gutter needs!
