From the first phone call to the last, Aaron and the whole team did a first-class job of addressing questions, finding a place for us in their schedule, and making everything come together that made our home really look fantastic. I would highly recommend Grandville Roofing to anyone that needs roofing or siding! Over the years we have made connections with contractors that we trust explicitly, and I can now say that we "Have a roofing and siding guy!"

Aaron was very professional and accommodating of my custom requests after an initial quote. Aaron was also quick to provide his insurance when I asked for it, which I definitely appreciated! Quote was reasonable for replacement of a portion of my gutters that had fallen into disrepair (around 30’ total, with 3 downspouts) as well as some soffit fix ups!
The Grandville roofing team arrived at a convenient time for me, were extremely friendly, and helped me understand the repairs they were making. Big props to John especially for getting into a hard-to-reach area under my deck for a downspout!
I fully intend to hire Grandville Roofing & Siding again for any future projects on my home.
