"Ramon and his company did an excellent job for us in putting on a new roof on our large, complex, old, shingle style Victorian house. The proposal was comprehensive and delivered quickly. We negotiated a few points and then went ahead. Ramon stuck to every detail of the proposal and his crew showed up on time to start the job. They appeared to be an experienced, excellent, hard working crew that knew exactly what they were doing. They started early each day and worked till after dark. And, Ramon's brother, Wilson, who was in charge of the crew, kept me informed through the whole process. They finished our very complex roof in just 2.5 days. The roof looks great and everything was cleaned up and back to normal by the third day."

"1. punctual on estimate appointment 2. three estimates were solicited all were equivalent service for product two allowed for Owens Corning or GAF and were certified as was On Top 3. The date proposed was mid October but the actual work was much sooner (low slope roof) and completed in several hours The roof has now gone through several seasons without issue. I recommended them to a friend of my wife"

"Its the weekend before Christmas and the roof is leaking. The local home improvement company said it would take 30 days for repair. I searched for roof shingles on google and pop this company. They got my roof fixed in a week. It's so fast that they guarantee it."

"Joe Hennelly and his excellent crew did a fantastic job on our roof replacement, from start to finish. First of all, communication with Joe was great, from the initial phone call to the day of the job and throughout the job. The crew knows exactly what it's doing and worked quickly, efficiently, and professionally. They took great care to protect our home and yard from debris as they stripped the roof. Perhaps most impressive to me was their cleanup: after they were gone, I looked long and hard around the property for any debris they might have missed, and found none! Honestly, there was no evidence in my yard that a roofing job was done at all -- except that the new roof looked great. They truly left things better than they found them. The price was very fair, the work was excellent, and the experience dealing with Joe and his crew was top notch. Highly recommended!"

"Moss was taking over my roof, and I was worried I'd have to replace it early. I found The Roofing Company on Angi, and they were incredible from start to finish. Dylan didn't just spray chemicals and leave; he took the time to manually prep the roof and brush away the heavy moss before applying a gentle soft-wash treatment. The transformation is night and day and my house has its curb appeal back, and I know my roof is protected for years to come. Professional, fast, and highly skilled. Highly recommend!"

"Fantastic! The estimate was clear and detailed appropriately. The product selection was high quality and appropriate for our project. The roof project ended up taking 1.5 days and not the originally estimated single day but I was pleased they didn't try to reschedule the remainder and instead simply arrived the next morning, completed the work, and cleaned up the yard well."

"Excellent! Kevin was very responsive and came by just a few days after I had requested an on line quote. He gave me a proposal with the full price and explained everything and there was no sales pressure at all. A week later he came by again and we signed the proposal and gave him a deposit. He had shingle samples and again explained the process and answered all questions. A week later a crew was at our house right at 7:00 AM and were stripping the roof by 7:30 AM, after covering the bushes and hanging down tarps from the roof to protect the house. They were all done by 4:30 - cape style house and two car garage. The crew did a great job, the roof looks great and everything was cleaned up. Kevin came by and did his visual examination and to make sure everything was OK. Great Job!"

"Adam Vaillancourt Roofing was the 3rd roofer to inspect my very simple repair job (replacing a single edge shingle) and the estimator (Adam) was the only one of the 3 to offer a repair right away. I hired him on the spot and he completed the job in about 1/2 hour for less than what the others quoted. Very happy with the outcome. Would hire this roofer again."

"the work was great, he went in their and cleaned up everything, and put in a piece of pad to cover it to keep the birds out; he also checked every part of the roof for any possible entries as well."
