We got all of this, and more, from Gauthier Roofing and Siding. Ron is prompt to answer questions, and provides detailed information about what to expect. Our new roof looks terrific. They showed up when they said they would (important to us!) to provide an estimate, and then showed up as promised in November 2020 to work on the roof.

We would highly recommend this company to anyone looking for a roofing/siding company."

Both times I’ve been very satisfied with every step of the process, from the initial estimate, to the installation by efficient and courteous crews, to the follow up and billing. I especially appreciate how welcoming Ron and his staff are of any questions I might have, and how dedicated they are to answering them in a timely manner. For me, peace of mind is an important need when it comes to large home projects. This company has, indeed, met this need and I’m very grateful."
- "We will definitely be using Gauthier roofing and siding for all the updates we want to do on our home. The professionalism from Ron and his staff was amazing. From day one starting with the estimate we were told to make sure that we get a couple of estimates from other companies. The nice man that came for the estimate answered all my questions and didn't make me feel incompetent for asking about something that I was told that I would need. He explained why that wasn't a good idea and he would have Ron get in touch with me regarding it. The Installation guys were amazing, respectful and the cleanup was beyond my expectations. Thank you guys you did an awesome job!!! You are a Great crew!!!! Great experience all around. My roofs looks amazing!! The workmanship speaks for itself and I can see why they have been around a long time with a great reputation. Will definitely be using them again!!"
