J & J Roofing just finished reroofing our home and did a fantastic job. I got 4 bids and this quote was in the middle. however Matt knew exactly what needed to be done and how it needed to be done. He was familiar with San Marino city codes. He was very clear and prompt.in his communications. The work began as scheduled and finished on time. The crew was very efficient, quiet, (as quiet as you can be while banging on the roof) and neat.
Everything was clean at the end of the day and all our landscaping was intact at the end of the job. I would definitely use them again and highly recommend them to anyone looking for a reliable roofer.

What a lucky Yelp find! J &J Roofing was a pleasure to deal with from our first contact. Jush came on time to estimate our roofing project - even calling ahead to confirm his arrival. We had our COMPLETE estimate including terms and conditions, guarantee, etc. within 24 hours. We had questions to clarify things which he immediately responded to.while on vacation. We scheduled our start date - no deposit required and work began as planned. Crews arrived early in the morning as shared and they worked all day taking breaks as if scheduled and then cleaning up before leaving each day. Justin in the office always called with updates and next steps.
The communication was and Justin was very courteous and responsive to any questions we had. We highly recommend this company and will be sharing their name with all our friends in need of roof repair or complete new roofs. BTW - We have an S-tile roof and these guys were great. Our bill was exactly the amount estimated. We couldn't be any more satisfied.

Got a few bids and decided on J&J. Mike answered my questions in detail and make sensible recommendations for fixing our roof. Justin laid out the schedule and coordinated each step for us - removal of old roof, inspection, new roofing, etc. All the workers that showed up were courteous and professional. It went as should. uneventful = good. Would definitely considering working with them again.

I didn't have a good experience with J&J I received an outrageous quote and the inspector Mike didn't do a good job. He literally came out for the inspection for 5 mins and wanted over $500 just to change tiles. I thought bloody hell Mate I could have hired a day laborer who could have replaced the tile for a fraction of the cost. Interesting man.
