  Greg was very. Professional making sure the entire roof of our home was covered. He cleaned up around the home. There were several tree branches over hanging the roof and asked if I wanted them removed. I gave him pruners and he removed the branches. He called back a few dates later to verify that all areas of the roof had been treated. He only charged what he had quoted. We are very pleased and would recommend his product and severe.

  Awesome to work with. Was punctual and worked efficiently. Price was more than reasonable compared to replacing our roof and hopefully added a few extra years. Very happy with Greg and his work.

  Greg removed and replaced a section of my roof’s shingles that had rotted. He worked non-stop on a very warm day and did a great job. Greg cleaned up and took away the rotten shingles. I would definitely hire him again.
