I contacted C & J Roofing regarding a new tar and gravel roof for my garage. They provided a competitive quote and were easy to work with – they have front of office staff that field phone calls / take messages. They’re by and large really friendly folks and seem to take pride in representing the business. The individual who ran our project was Paul. Paul was a breeze to work with – and I say this as someone who is fairly concerned about details. He is easy to get in contact with and shows up on time. He is patient with all questions and provides clear answers. They worked around the schedule of some electricians we also had on-site, and gave me clear instructions as far as what to communicate to them to ensure no one stepped on the others’ toes. As rains began to show up, Paul was very responsive in coming out to take a look at issues I identified. Water wasn’t draining as expected and led to some pooling in a garden of ours, and within less than a week Paul was out to take a look at it and come up with a solution that he did not charge me for. He comes off as nothing but honest and sincere. In the future when I ultimately need to get the pitched part of my roof redone I will absolutely contact C & J before anyone else. They are my roofers of choice now, and I let anyone who needs roof work done – especially in South City (South San Francisco), which is where Paul runs jobs I’m to understand – that they should hit them up first, too.

C & J Roofing Co. put in three skylights in my dining area and made my house sing. I was uncertain about how to place the skylights and how many I should put in so the owner Coz did the thinking for me (free of charge) with a fabulous designer result. These guys work quick and efficient. Very professional job and well worth the money. The skylights are beautiful. You are in good hands with C & J. They also installed the roofing around the skylights. Really nice job.

I work for a Property Restoration Company and we frequently use C & J Roofing. Coz has a great response time, his team is efficient, and he always goes into great detail about where the problem is and how to best fix it. He is my go-to roofer and I’m very impressed with him and his team.

Great service from C&J Roofing! We had a leak in our roof which we wanted to get fixed before El Nino hit this winter. We were scheduled just a couple days after I called with Paul for an estimate. We received the estimate and contract via e-mail and were able to schedule the work the following week! Paul and his crew patched our roof within an hour and explained everything he did before he left. I received an invoice a couple days later in the mail. The entire process of contacting C&J Roofing, getting an estimate, and getting the work done was so easy. I’m sure with fall/winter closing in, they are much busier so it may be a little harder to get a hold of them (I’m just assuming because I’ve heard all of the roofing companies are swamped with everyone panicking about El Nino) but I couldn’t give more praise to them!

I left a message for C & J Roofing, we needed a roof leak repaired. They got back to me the next day and apologized for the delay. The were just hammered with calls. I set up an appointment for an inspection and estimate. The inspector became available a day early and got here an hour sooner than planned. He was very professional, obviously very experienced and quick. I accepted the estimate and scheduled the repair. Repair crew showed up on time, quickly fixed the roof, cleaned up and left in about an hour. They even removed the tarp I had placed over the leak without being asked to. Very pleased. Obviously no more leak. C & J Roofing is at the top of my list to get the roof replaced come spring! Thank you C & J Roofing!

As others have said, if there were more than 5 stars to give, I’d be doing so. I needed a roof repair done before the next rain. When I found these guys on a Friday afternoon, I called. They replied within the hour, came by the next day (Saturday) to assess the problem, and sent their crew over on Monday to fix it. The job was done very quickly and efficiently and they cleaned up do well that you’d never even know that they were here. And the bill was amazingly low compared to what we had anticipated. This company is outstanding and I recommend them wholeheartedly!

I wish there were more than 5 stars to give them. They just finished our HOA roofs in San Mateo over the course of 6 months. Our roofs look beautiful. Coz was great to work with–including Paul and all the other workers. They always accommodated our needs as a community–ready to assist in any way in order to make this project less painful. Coz met with us once a week to update us on progress, so that we could notify the community. We will be using them to install additional skylights in the spring–knowing the Coz will be doing the designing and installing. Thanks Coz and C&J!!

Have had wonderful work done by C&J roofing company. Could not find one around who could come out quickly, if at all, before I found this company. Since asking them to check on some loose tiles last year and getting those fixed as soon as contract was signed, I have peace of mind as to whom I can turn to when I have issues with my roof now. Good to know they will do gutter replacement from previous review. Most recent work was for a leak and we had Javier come out to fix that, too, in between the heavy rains recently. So far, garage ceiling has been dry, Javier. Thank you! Thank you to Paul and Yvonne as well for always being quick to respond!

C & J Roofing Co. Inc. is a splendid group. Coz Giannoulis runs a really good ship and his team does a great job. They came to our rescue as quickly as they could when the water started coming in. It became clear that we needed a whole new roof and they began as quickly as possible and did great work for us. You will be in good hands if you need to have Coz Giannoulis expertise.
