We just had a roof put on our home and we cannot give a high enough rating for the pricing,…read moreprofessionalism, and quality. Our experience started with the first initial estimate, provided by the owner Mr. George Denison. He gave us a prompt and extremely fair quote for all labor and materials which are warrantied. A neighbor had replaced a roof, two years prior, which was the same as ours with a company who had charged 3k more. Everything was documented and any questions we had were promptly answered. The workers on site were hard working, polite and beyond professional. The site was cleaned up each day and the finished product was outstanding and completed in two and a half days. They came to finish the job on a Sat morning. After the first day of work, we actually received a call from Barbara. She works in the front office and she called to just check in with us to ensure that we were satisfied. They told me they have been in business for over 50 years and I definitely can see why. If you need a roof done you only need to check out one place. That is GA Denison and Sons Inc.

Estimate was fast, competitive and accurate (no paying for wasted materials). Workers were excellent, cleaned up daily for a 2.5 day job. Yard and plants were unharmed and clean. Best part is we got a beautiful complete new roof, fully up to code with a 40yr warranty. Our neighbors recommended them to us and were recommending them to you.

We entered into contract with this company in December of 2018 to install a new roof which included…read morea ridge vent (for ventilation). On the day the new roof was installed we arrived home from work after dark to a dumpster filled with old roofing material and on the top of the pile was quite a few empty beer cans and beer boxes, I knew this was a bad sign so I took photos of this. 3 months later the entire roof leaked because they forgot to put the water and ice barrier down. They also did not install the ridge vent (we questioned this via email and the owners response was he couldn't because of the pitch of the roof which is rediculous, you can put a ridge vent on any roof!) Due to the lack of ventilation it caused black mold in the entire attic. They came to fix it by installing the water/ice barrier material that they forgot to put on in march of 2019 but still did not install a ridge vent which is needed to vent air into the attic. I repeatedly voiced my concerns to the owner about the mold and he emailed me that it wasn't mold, just algae and it would dry up. Its now 14 months later (and we now have become very educated on roof ventilation) after several emails back and fourth to the owner and a final phone call to him which he became extremely belligerent, told me it's not his fault and told me to F off and hung up on me. We now have hired a very expensive mold abatement company and also had to pay a new professional roofing contractor to install a ridge vent which was in my contract with JS&R Roofing. Such a nightmare!!!

From start to finish, their professionalism, efficiency, and attention to detail were outstanding. A special shoutout to Dennis and Rells who went the extra mile on a cold, windy day to clear off debris from my roof - that was a huge favor ! This company definitely has a commitment to excellence and I am beyond satisfied with how everything turned out.

KlausLarsen Roofing began work on a neighbors roof in Suffield, CT May 28, 2026 without pulling a…read morepermit. The homeowner is well known as a bigot. I noticed workers stripping the roof into my backyard without permission. When I went out to speak to the workers, none spoke English. Site manager Mark Libiszewski came over and I explained he didn't ask permission and does not have permission to strip the haters roof onto our property. The bigot called police. That is when it was discovered no roofing permit had been pulled. Site manager blamed it on a 3rd party error. Police explained [on video + audio] work came to a halt & once a permit is pulled work will resume within 10 to 14 days. The site manager will come to my house prior to work starting and touch base. No stripping will be done on our property but workers will come over to pickup errant debris and nail sweep with a magnet. Five days later, June 2, I noticed tarps, plywood, and workers stripping the neighbors roof into our yard. When I walked over to confront the same site manager the tarps were coming down as the roof was speed stripped by the hard-working crew. I reiterated to Mark he did not have permission to strip the bigots roof onto our property and if he needed that kind of access we should be compensated for it. Mark said he had no authority to compensate and they always go onto other peoples property when needed. Mark also said Suffield Police said we gave permission and insinuated I was calling police a liar. I subsequently called KlausLarsen office and spoke to Cora, Production Department, who told me I need to speak to Joanie Dunstan Mgr. Two days later I connected with Joanie who had to speak to someone else and then would call my son who owns the property. Needless to say my son is still waiting for a call. In summary, KlausLarsen did not pull a proper permit initially, feels entitled to send equipment & crew onto other peoples property without permission even when told not to. We inadvertently helped a bigot get his roof done by a crew of foreign hard workers he despises and our yard was the receptacle for the bigots roof trash. I cannot speak to pricing or quality of work but I can speak to the unprofessional and disrespectful manner in which we were treated.
