Working with Tim quashed any hesitations about shady contractors each step of the way! He promised and delivered at every level....I would recommend Tim to anyone if they are in the market for a new roof. I looked around and I just felt comfortable with Tim.

Tim is amazing! He looked at our roof and then sat down and explained everything to us and let us know our options. Tim was very knowledgeable....if you want a great, easy experience when fixing or replacing your roof, he is the person to work with!
Rob was great to work with on a complicated project of new and old roofing assemblies that also included a wall panel system. From pre-con through construction, he came to the table with the interests of the owner, project budget and schedule in mind. Great team player!
