We had a great experience with Tri-County. Our house needed a new roof and gutters, and project manager Erik & the staff made the process easy. From material selection at the office to the fast and efficient tear-off and replacement, we couldn’t have been happier with the project and results. The project was done in a timely manner, the cleanup was excellent, and on site follow up from Erik guaranteed everything was completed correctly. We couldn’t be happier.
