Your home has a story. The best exteriors do, too.

Maybe you’re dealing with a roof that’s starting to show its age, siding that no longer looks the way it should, or windows that never quite keep the cold out.

Amazing experience with Gerry’s Roofing & Siding Inc for a roof repair! Water was coming into my 2nd floor bathroom and quick action was needed. From the first call with Marlene and the expert repair from Matt only a few hours later, this team goes above and beyond. Extremely professional, friendly, knowledgable, clear steps and great pricing! Highly recommend and can’t thank Matt enough!

Rachel R.

Gerry’s did our Guttergaurds this fall. Top notch service from start to finish. Alex thoroughly explained the various options to us and helped us choose the product that best suited our needs/location. Communication between Gerry’s staff (pre-install inspection/measurements; install crew) and us stellar and respectful of our schedules. Highly recommend Gerry’s.

John W.

Thank you to the team at Gerrys Roofing and Siding. The results of our siding are spectacular. It looks like a completely different house! A special shout out to Al, Ben and Fred. They did a wonderful job and are a great team. They even helped to move a shed that was in the way of the project. We would highly recommend them.

Roman S.

I received a door hanger! So glad I called had Matt come out to provide a quote. We decided to move forward and shortly after received an email from Kajal letting me know of the process for completion. It was done quick and easy with no issues. The next day Bernadette reached out to follow up and make sure we were happy with everything!

Lori R.

I am very pleased with the quality of work! Robert and his partner were very good at their job of putting up our rain gutters! Robert is very conscientious about his work and is working to fix a leak over the deck! The team that put our snow guards on the roof were very good also! I would recommend Gerry's Roofing !

Charlotte R.

We recently had our roof done by Gerry’s Roofing. They did an excellent job and John and I are happy with their work. The crew Ian, Cole and Alex did a great installation. Doreen kept me well informed. Greg came by and completed a final inspection in a professional way. Bernadette was so kind and willing to answer any further questions we had. We definitely would recommend Gerry’s Roofing.

Margaret V.

The roofing crew was pleasant and helpful. The new roof looks pretty good. They did a really good cleanup job. I also had the eavestroughs, fascia, downspouts and soffits replaced. All of the work was completed the same day and to my satisfaction. Everyone whom I dealt with at Gerry's Roofing & Siding Inc have been very helpful and pleasant.
