J & J Roofing

J & J Roofing handles roofing work out of their office at 1485 Lincoln Ave in Pasadena. They take on roof repair, roof replacement, inspections and maintenance for homes and commercial properties across Pasadena and nearby Los Angeles areas. The company holds contractor license 761462 and keeps a brick and mortar location rather than operating from a truck. Matt serves as the main contact for bigger decisions while Justin Mack handles operations and customer questions on site. Crews include Alex, Carlos, Josh, Courtney, Mike, Abel, Alfredo and Menji.

Homeowners call them for full roof replacements on houses over thirty years old, targeted leak fixes that avoid tearing off the whole roof, and same-day repairs ahead of a sale. One customer needed only a partial fix on a fifty-year roof that cost under five hundred dollars after other companies pushed for complete replacement. Another had Alex inspect and patch small issues during a checkup that prevented future problems. Last-minute holiday weekend repairs let one family close on their house without delay, and crews finished a full replacement in two days while keeping the yard clean.

They show up on time, answer calls quickly and lay out options with photos instead of pressure tactics. Pricing comes in competitive with other bids and payment terms stay flexible. Crews work fast, respect the property and leave the site cleaner than they found it, even clearing gutters during repairs. Communication runs through the boss for big calls and the supervisor for daily details, with responses that stay clear and direct. Service covers Pasadena and the surrounding communities, and they have handled both residential and commercial jobs for the same clients over fifteen years.

Reviewers keep noting the solid workmanship, fair prices and reliable crews that show up when promised. The company earns consistent five-star marks for staying organized, finishing on schedule and standing behind the work long after the job ends. DIRT Score 4.5 from 72 reviews on Finds.

“Our new roof from J and J is gorgeous and the process was excellent. View of our house from the curb is mostly roof, and J & J guided us to a beautiful and durable total replacement for our 30+ year old roof, choosing not the cheapest, but definitely not the most expensive material: we picked Certainteed Presidential Solaris TL in Country Gray and the result is magnificent. The communication skills from J and J were exemplary. They have a very accessible-at-all-times boss, Matt, for big strategic questions; then a supervisor, in our case, Justin, who answers more specific questions and figured out the weird tiny details of putting a roof on our eccentric 76-year-old house; then a foreman, actually on the job site, Marco, who has the how-to knowledge and directs the crew. All the workers a”

“I have worked with J&J Roofing on multiple projects over the years and have consistently been impressed with their professionalism, workmanship, and reliability. As an interior designer, I regularly recommend contractors to my clients, so it's important that the companies I refer are trustworthy and deliver quality results. J&J Roofing has never disappointed. They are responsive, knowledgeable, and take the time to explain the scope of work and available options clearly. Their crews are punctual, respectful of the property, and maintain a clean and organized job site throughout the project. Most importantly, the quality of their roofing work has been excellent, giving both my clients and me confidence that the job has been done right. I would not hesitate to recommend J&J Roofing to hom”

“J&J Roofing came to me highly recommended by a close friend. They know their stuff, are well established; licensed and insured. They did a replacement on my roof in 2 days. Gave me options and answered all my questions. Their pricing was competitive (compared to other quotes I received), as were their payment terms. They have a brick and mortar head office (not working out of a pick-up); and their Director of Operations, Justin Mack, who, working in a customer relations capacity with me, I found to be very helpful; courteous; knowledgeable and quick to respond. In turn. I would heartily recommend J&J Roofing.”

“4/24/2026 J & J Roofing installed my roof about 6 to 7 years ago. It has been completely trouble free. No leaks, no issues. Still, seven years in the sun is a long time, so I called them for a “Roof Check Up.” Alex came out, moved across the roof like a spider on a web, found a handful of non-serious issues, and fixed them on the spot as part of the checkup. I had a lot of questions about the condition of my roof and roofing in general. Alex could not have been more obliging. I know he is time constrained during a visit, but he clearly and succinctly addressed every question. It does not get any better than that. Thank you, Alex. As an aside, I also asked him to touch up the chimney flashing, the vertical metal piece where the chimney brick meets the roof tiles. Mine was structurally f”

“J&J have been our roofers for over 15 years (both at home and at work) and has always done a great job right when they said they would. We recently sold our home and had them do some repairs at the last second (on a holiday weekend) to make sure we finished the work before sale closed. Can't thank Mike and Justin enough for getting things scheduled under duress and Carlos, Abel, Alfredo, and Menji for great work on a Saturday. I cannot recommend this company enough.”

“We have been working with J&J Roofing since May of 2022. At that time, we suffered damage in a room during the rains and interviewed many roofing contractors. All of the roofing contractors other than J&J Roofing advised us to re-roof our entire house. Even though the front half of the roof of a 50 year roof (which was installed before we owned the house and J&J Roofing as not involved) has not lasted anywhere near 50 years, the front side and back side have worn differently. All of the other roofers would not even re-roof just the front half - it was all or nothing. J&J said that they could easily repair the issue without re-roofing and it cost us less than $500 for them to repair it. The repair worked. Almost four years later (and they had told us that at least the front half of the roo”

“Alex from J&J roofing came to do a repair job for a leak we had. He was on time, very professional, listened, and took his time to complete the job the proper way. I'm handy myself, perfectionist and not easy to please, but I was very impressed by his work.”

“J&J has taken care of roofing at my sister's home and my home for many years. Recommend this company to everyone for home or commercial needs. We have had both new roofing and repairs. The work is quality, pricing is fair, and customer service is great.”

“I recently had a new roof installed by J&J and was very pleased with the work and service they provided. They were extremely professional and provided a competitive price - as well as ensuring that all my needs were met. I worked with Josh and Courtney who were great. They made sure that everything was perfect and that I was pleased with the outcome. The work was completed in two short days and the site was completely cleaned. I definitely recommend this company to anyone contemplating a new roof.”

“J&J were thorough, courteous and prompt with all their communications. After performing a complete inspection and diagnosis of the roof’s issues and probable cause of the leak they offered a variety of options as to address the issue with photos and their best recommendations (and it wasn’t the most expensive choice). No hard sales just straight talk. Their team, led by Carlos, worked fast and left the area cleaner than I left it (my gutters appeared to be free of debris too!). When it’s time to redo the whole roof, I’m calling J&J.”
