Recommended Customer Reviews

Former neighbors in Cardiff recommended this company but we thought we should do our due diligence so we had four roofers come out. Luis Gastellum was the only one who actually seemed interested and the sole tradesman who got on the roof to examine it. His estimate was reasonable (middle of the ones we received) and he was accommodating to our schedule. His workmen were dependable, showed up on time and cleaned up meticulously every night. Luis came by to inspect periodically. When a hurricane threatened less than halfway through the project, he made sure the men got the two layers of paper down (by working on a Saturday) and he personally came by on the day of the storm to ensure we had no leaks. When the Carlsbad inspector came for the final sign off, he mentioned how much he liked this company and said we'd chosen well. We think we did.

We are SO happy with this company. The bid was fair, everyone showed up on time, cleaned up every day, and the house looks great. They also took care of the permit.

We had our roof done a few years ago by Gastelum on our side of a duplex. They took great care to make the roof look clean and sealed between ours and our neighbors roof, who was not ready for a new roof.
A couple of weeks ago, our neighbor decided to get their roof redone, but hired someone else. You could see from the ground, things weren't right. I asked Gastelum if they would give an inspection.
They were so polite and kind and came quickly, without expecting anything but to help. Upon the inspection, they found several serious issues with the section the other roofer worked on, leaving damage and unsealed sections between the two roofs. We were provided pictures and videos, so we could show the other roofer and homeowner.
Thankfully we were able to have Gastelum to the repairs also, as we knew they would do the job right.
This company has earned their five stars!!!!!

I should have written this review sooner. I just walked into my garage and it is much cooler than it has ever been thanks to Gastelum roofing. It didn't occur to me I needed better ventilation but the very fair quote I got from Luis included 2 new roof vents, new fascia and some tricky reconstruction where a company that installed a sunroom tore off part of the roof and cut off rafter ends. The roof looks great, the crew put 2 coats of paint on the new wood. They showed up when they said they would, he charged the price quoted and finished on the finish date. Rarely have I had such a positive experience with a contractor. Would give 10 stars if I could even though I had to wait in line to get it done. Gastelum Roofing is very busy.

Gastelum Roofing the most amazing company I have dealt with in my life. I'm sure there are other good roofers out there, but this is unbelievable. After having watched him to six homes in our neighborhood I contracted to have my California tile roof redone. His price was more than competitive, the workmanship exquisite. Attention to detail, the knowledge of the job, showing up on time and always leaving a clean job site till he was finished. my gosh the owner actually participates in the work. I also had a lot of wood damage which I figured was going to cost me alot, but he did not take advantage of the situation. This company is the best.

I had estimates from 3 companies for Roof replacement and some wood repair. 2 of the estimates said wood repair to be determined on top of the cost to replace the roof. Gastelum came out and did a complete walk around and on the roof and included the wood repair in the estimate for roof replacement. He came in much cheaper than my other 2 estimates. He did an excellent job and the work was inspected by the city of Oceanside. I met the city inspector after he completed his inspection and he said Gastelum Roofing is one of the better companies in Oceanside that he deals with. Also, my HOA also had to inspect his work and passed without problem.

Luis is the most professional friendly business owner! I highly recommend him. He is on time, cleans up, and provides photos before and after. His prices are fair and reasonable. I have already recommended him to a friend in the neighborhood. I cannot say enough positive things about Luis and Gastelum Roofing! I absolutely will use them again!

Gastelum Roofing replaced the roof on my 3-story apartments last year and did an amazing job for a great price. Anything underneath that didn't look great or had visible water damage was replaced and sheeting was even added to areas that never had it. The structural integrity of the roof is actually better than when built in 1975. I just had them back to replace the decks and balconies and they gave the same professional, expert work...everything is water-tight and beautiful. If they are available, hire them.

Great owner, very knowledgeable and very fair with his prices. He was recommended to me by a neighbor in Rancho Bernardo and he provided the best price for our house there. Some time later (Sept 2018) he provided the second best price for our house in Poway and then matched the best price we had obtained. We hired him to install a new roof there. The crew was on time, all work was permitted and inspected and the clean up was done well. All on time, all on budget and a good job overall.

I'm surprised these guys have so few reviews. Louis and his team did a great job on re-roofing my house. They were very nice, fast, professional and answered all my questions. Highly recommend!
