What homeowners say about our work

Doug Tong

Paragon Roofing completed a complicated roof installation in San Francisco for me where 5 layers of old roof needed to be removed before installation of the new roof. It took about 5 business days. Ofir was very responsive, always answering my calls and texts quickly. I would definitely hire again for roofing needs.

I would HIGHLY RECOMMEND Paragon Roofing for their consistent communication, competitive pricing, high quality materials, and clear follow-up. I am a thorough researcher and did a lot of this prior to finalizing with Paragon – especially give the big job and expense. We unfortunately had to have 2 complete roofs redone at the same time – my parents’ and mine (new roofs). We wanted the same company for both, but only if they could deliver. Paragon went above and beyond! We had extensive communication before, during and after each roof, which were done within a few months of each other. We were provided with several options and it never felt like a hard sell. We had 4-5 other roofing companies for estimates so we had some comparisons. Paragon matched the other bids, but with higher quality materials. We discussed some potential changes that might happen after the roofs were torn off – and, of course, there were changes! However, there were no surprises because of the communication. One roof came under the original budget (rarely happens) and the other over (due to larger unforeseen issues). When the issue came up, Nelson walked about and clearly explained what was happening and the best way to fix it. They were also done on time once the work started. They also came back afterwards to fix some cosmetic things on the skylight afterwards. We were not originally planning on a skylight, but once we had to do the whole roof, we got estimates and were able to fit it in. We had photos throughout the entire process – before, during and after. They also sent in cleaners due to the mess from the ceiling. They will not leave until they make sure you are satisfied. I also had to contact Nelson months after the work had already been done to get receipts, extra photos, etc. for accounting and insurance purposes. He knows who I am and I felt like I was still a current and valued customer, not like they did the work and then left us.

Last winter's storm blew some shingles off my roof. I decided it was time to replace the roof after 27 years. Having heard many stories about unscrupulous roofers, I spent 10 months researching and reading up on blogs, reviews and company websites. I interviewed quite a few roofing companies. They are all reputable and established companies with good reviews. Nelson convinced me to choose Paragon for the job. He showed a lot of patience answering my questions, he was warm, sincere and showed a genuine willingness to meet customer's needs. Nelson was reassuring throughout the process. What impressed me the most is his promptness in replying to phone calls or texts. He took the time to listen to my concerns and worked to resolve issues timely. The entire roof was replaced in two days. Nelson showed up both days to make sure things were done properly. The crew worked long hours and were professional and efficient. The project had some wrinkles due to city hall's skimpiness in its inspection process despite very exorbitant permit fees. Nelson tried his best to address the city's deficiencies. Paragon did a good job on my roof.

I called in Paragon roofing to replace my old roof and i liked the work they did. Especially Mr.Nelson was very professional, responsive and accommodative for all my request. They did the work on time and it was clean and neat. They took a good care of a small valley on my roof to put necessary good quality materials to cover it well. The price was very competitive among many quotes i received from different vendors at that time. i did and would recommend them to my friends for their roof needs.

I recently hired Paragon Roofing for a full roof replacement at my home in Daly City, and I couldn’t be more impressed with their work. From start to finish, the entire process was smooth, professional, and completed exactly on schedule. One of the biggest challenges with my property is the tight, space-constrained area around the house—but that didn’t slow them down at all. The Paragon team handled the logistics with ease, showing clear experience working in compact residential settings. They kept the site clean, organized, and safe throughout the entire project.

We recently had our office roof replaced by Paragon Roofing in San Francisco, and we couldn't be happier with the results. From the start, they provided a clear and realistic timeline—and most importantly, they stuck to it. In a city where delays often feel inevitable, Paragon was a breath of fresh air. The quality of the work is excellent, and the site was left spotless when they were done. If you're looking for a reliable roofing company that delivers on their promises, Paragon Roofing is the one to call. Highly recommended!
