Last year we had hail damage to the roof and siding on our house along with most of Oak Creek. We had that work done early this year.

We decided to have the garage sided to match with new gutters etc. Very happy with the results from Tri-County Contracting and would recommend them to anyone needing exterior work done!!

I had a very pleasant experience working with Tri-County. I had bid out my roof replacement project to several contractors and Tri-County had the best price and package.

Thanks Mike!
