At Three Tree Roofing, we bring our best to every roof we install. Whether it’s a small home or a large commercial building, quality and care guide everything we do. Each year, though, a few projects stand out—not because they’re better, but because something about them is unique.
Our “Roof Replacement of the Year” series highlights these jobs. It could be the design, the craftsmanship involved, or the way the roof impacted the homeowners or community. From detailed residential roof replacements to complex commercial installs, these projects show what the best roof replacement can look like when design, quality, and purpose come together.
