“

I called Jeremy in urgent need of getting my roof done due to a massive rainstorm that caused a leak in my home.<br><br>He was able to re-arrange another client to another day and came the next day to have my entire roof done! I was so grateful as I was scared for another rainfall with a damaged roof.<br><br>His crew was professional and cleaned the site when finished. He provided photos of the roof and showed us the damaged plywood. His prices were reasonable! Great communication and work.
