We are pleased with the work done by MJJ Roofing & Siding. Everyone we spoke with during the process was great. Dan came out and gave us an estimate, and we signed up. We received calls letting us know when the work was scheduled and when the crew was on their way. Each crew member knew what needed to be done, and they went right to work. Very efficient and professional. If we had any questions during the process, Jose was right there to provide the information we needed. When he had to leave, he made sure we had his phone number. Tarps were used to contain the roofing debris, and they did a great cleanup before they left. We highly recommend this business for your roofing needs!

THE CREW WAS ON TIME AND VERY EFFICIENT. THE FOREMAN EXPLAINED WHAT THEY WOULD BE DOING AND WAS AVAILABLE FOR QUESTIONS DURING THE WORK. THEY PROTECTED THE AREA AROUND THE HOUSE WITH TARPS AND EVEN BLEW THE TRACES OF SHINGLE GRIT CLEAR WHEN THE WERE DONE. THEY EVEN REPAIRED A HOLE IN ONE OUTBUILDING ROOF THAT I HAD IDENTIFIED BEFORE GETTING THE ESTIMATE. I RECOMMEND THEM HIGHLY.

Great experience. Estimate was on point and exactly the cost. Super communication through every step. Crew showed and made quick work of the shingle replacement, checking in throughout the process to make sure everything was understood. When they left, the site was spotless and couldn’t tell they had been there except for a new roof. Highly recommend.

I interviewed and met with a few of the top outfits in Maine. These guys know what they're talking about and use the best products. The very best communicators, from the first call to the final thank you(you just don't see that anymore). I was impressed and actually prepared to pay more to work with them, but, they had the best price too! I recommend you make MJJ your first call.
