205 Euclid Ave, San Bruno“Excellent service from start to finish. Cleaned the gutters on our two-story home and repaired an issue we were having, all on short notice.

204 School St A, Daly City“I reached out after spotting some cracks on my parapet walls, and I’m glad I did. Alexis came by within a couple of days, explained exactly what was going on, and gave me a clear plan without any sales pressure. The crew showed up early, worked hard even in the warm weather, and handled the repairs quickly but carefully. They cleaned up so well you wouldn’t even know work had been done, except now the roof and stucco look better than they have in years. It felt good working with a company that’s straightforward, reliable, and genuinely cares about the end result.“

1150 Key Ave, San Francisco“I've worked with this roofing team on several projects at my San Francisco property, and every time they deliver the same high-quality results. When Patrick gives you an estimate for your roof repair or replacement, that's exactly what you pay—no hidden charges or surprises. They always schedule the work quickly after providing the estimate, and the job gets done faster than expected. Patrick and Ernest are both very patient and attentive, always listening to my concerns and making sure I'm comfortable with the process. The crew often goes above and beyond, taking care of extra details around the roof without ever asking for additional payment. Their workmanship is thorough, and they stay focused on the job until it’s finished. They use only top-quality roofing materials, and the final results look fantastic. After the work is done, they make sure to clean up completely and remove any leftover debris. I’m always impressed with how professional and reliable they are. Highly recommended for anyone needing roofing services in San Francisco!“

550 Marine View Ave D, Belmont“Allan's team did a fantastic job installing their lightweight Slate 2 system. After 2 years it still looks great, and I expect it to last another 50. They really showed high level craftsmanship in all their custom fitted copper installations, including large rounded roof and dormer sections, oversized flashings, along with gutters and downspouts of course. They were open to specific design discussion and requests, and they always delivered on their promises - including finishing at the cost and timing they estimated.“

3711 Colegrove St, San Mateo“The Gutterbusters was recommended to me by an established roofing company. It was a pleasure doing business with Steve, and I highly recommend him. Initially, he may not have a lot of patience to write an elaborate contract, but he still worked with me to type things up when I expressed my concerns. The work started and finished as promised, and during the period Steve went above and beyond to point out and helped me with things he observed around the roof+house that required attention. If you end up going with this company, be sure to treat him nice as he's been extremely helpful and respectful to his customers. Isn't that how it's supposed to be for all of us?“
8AM - 5PM
1525 Bancroft Ave, San Francisco“I had Ace out to assess my roof. I had multiple companies come by, and they were the first people who I felt really gave me an honest assessment of my roof--the only ones who felt that it needed a heavy maintenance rather than complete overhaul.I appreciated that John showed me exactly the areas he was concerned about and WHY. He did not treat me as an ignorant homeowner, which many companies seem to do these days.I haven't had the roof maintenance done yet, but when I do, I'm for sure giving my business to Ace!“

233 S Maple Ave Bldg. O, South San Francisco“C & J Roofing replaced the roof (extra work), had a lot of work on the garage (roof) along with new gutters at a home in Daly City. Every step from estimate to clean up was made easy for us by working with C & J Roofing Including the office staff.“
8AM - 4:30PM
1340 Underwood Ave, San Francisco“Professional, courteous and reliable service from the first phone call I made until they finished up the job. Everyone from Eduardo, who does the estimates, to one of Foremen, Roberto and all the workers, it was a pleasure. When they finished up, they made sure everything was cleaned up. I would not hesitate calling Excelsior again. ?“
