Customer Reviews
We can’t say enough about how pleased we were with John and his crew as they installed our new roof. They were replacing the one they had installed a couple of decades ago that had served us well but was showing its age. They were so easy to work with! They communicated well every step of the way, they showed up when they said they were going to, their installers were brilliant and worked super hard throughout, and they did an excellent job of cleaning up when done. John and his son even came over after the job was done for a final inspection. Congratulations on a job well done! And… we now have a roof with a 50-year parts AND labour warranty, so we never have to worry about our roof again!
