About three years ago we discovered we had a leak somewhere in our roof. The roof was about 20…read moreyears old and installed by the original home builder. I called around looking for an emergency repair and all the roofing outfits I spoke to either weren't interested in a small patch job, didn't want to do a repair without a commitment to an entire new roof, or couldn't come out in any less than a couple weeks. Except for Cahill Roofing. Mark himself called me back and came out immediately - on a Sunday. He crawled around my unfinished attic and found a spot where the plywood sheathing had warped - the source of the leak. I asked him how soon he could send someone back out to do the repair. He said he had what he needed in his truck and would make the repair on the spot. He braced the warped plywood and replaced some shingles. Mark really saved the day, and at a reasonable price. After some research I realized we had exceeded the expected 20-year lifespan of the roof and decided to replace it. We didn't want to push our luck as the roof was old and had already failed once. I called around for estimates. Based upon a competitive bid and our prior excellent experience with the repair we selected Cahill Roofing. We picked out the shingles, nailed down timing and were ready to go. The day before the job we decided the shingles we selected were too light and wanted a darker shade. I called to see how hard it would be to change at the last minute. No problem and no restocking fee or upcharge. Mark arrived the day before his crew to do some prep work and shingled some of the tougher spots around dormers and an atrium window. His crew of perhaps 10 men and women arrived the next day and were like ants crawling all over the house. The old roof came off and the new one went on in a single day. The roof looks fantastic! I have never found a nail, piece of shingle, or any debris around the house which is a major safety concern with kids and pets. My new roof was installed on time, on budget, and without any complications. Mark and his crew were professional throughout the process. I recommend Cahill Roofing to my friends and neighbors without reservation.

Roofs tend to look great at installation. The big questions are how long will the roof hold up? How…read morewill the company respond if there is an issue? This review describes our experiences with Cahill roofing. Our interactions have not measured up to his motto of with "honesty, integrity, and top-quality craftsmanship." Our interactions had three strikes - he was defensive before looking at the work, he denied there was an issue when he inspected it, and he had no interest in discussing what an independent analysis of his work showed. Nineteen years ago, Mark Cahill replaced and installed the entire roof of our house including rafters, plywood, shingles, vents, etc... The roof had a couple of significant leaks since installation. Mark Cahill was relatively cooperative during the first leak at around the ten-year mark. He did the repair for an additional charge. During the most recent known leak, which independent professionals have stated has likely been going on for a long period of time, his approach changed drastically. We lost electricity on one-side of our house and after three visits from our electrician a leak in the attic was discovered. Our electrician concluded that this was the likely cause for our power outage and told us that we should get in touch with a roofer. We contacted Cahill immediately. During the initial call, before even coming to the house, he blamed the water in our attic on everything from a humidifier that only runs for a few hours over night in the winter, to the bathroom vent, as well as the roof angles. When he did come to the house to inspect the issue from the inside, he decided there wasn't enough air flow coming through the attic vents (which he could've set up properly when he rebuilt the roof initially) and stated that our granite chimney is impossible to make water tight. He seemed particularly fixated upon our granite chimney being a challenge and was unwilling to commit to the possibility that there was an actual leak in the roof. (If he is so intimidated by granite chimneys then why did he accept work he is unable to perform correctly?) He came back a second time to investigate the roof itself and concluded that the issue was chimney pointing. It was pretty obvious to my wife and I that there was a leak and you can't fix what is not acknowledged. We decided an independent opinion was the best path forward to evaluate our roof. We asked Nick at NJP Contracting to evaluate our roof with a roofer he trusts, Quinn at Eco Pro Roofing. Nick has helped us for years with multiple properties and his work consistently holds up really well. They found significant issues with the setup of the "cricket box", which connects the roof to the chimney. The cricket box had two primary issues - the angles were too shallow and the flashing was incorrectly setup. Specifically, the flashing had two main issues: it went under the shingles as opposed to on top of the shingles and there was no channel put into the granite for a uniform interface between the roof and chimney. Not surprisingly, these two issues led to water getting under the shingles destroying the ply underneath. I called Cahill to discuss what the independent review found and to get his thoughts. I was hoping to negotiate a fix. Instead, he told us he had plenty of work and was not interested in repairing the work - we should go through someone else to repair his poor craftsmanship. Eco Pro roofing ended up repairing the damage and after two days of heavy rain it was apparent water wasn't getting into the house anymore. They replaced a significant amount of plywood, properly angled the cricket box, and installed the flashing in a way that could handle the amounts of water needed.

When we were ready to have the whole roof replaced, their response times were always quick.

Our entire roof was done in one day, and they even did some minor maintenance on the woodwork around the roof. Our new roof looks beautiful and perfect and we're very happy.

Long story short, the shingles that I chose continued to fail in a very sun-exposed area of my roof. That was my mistake: not going with the shingle recommended. Rob, the owner of this business, always responded promptly when a shingle failed (six times). Each time, he immediately responded via text and came that day to the house to make repairs. In the end--today--he brought his crew to my home and completely reshingled an entire section of my roof at no charge, refusing to share the cost with me. Please see my earlier review for additional details about my experience with Granite State Roofing. This kind of integrity is remarkable.
