Sherry Perlberg
Great service! Very professional! I wasn’t expecting a free inspection a year after I roof was done.

From my initial contact to completion of the job, they made the whole process easy with “ no drama”. I had many neighbors stop by to ask who was replacing my roof, because they were so impressed with how conscientious they were covering bushes and collecting old roofing materials. My new roof looks beautiful and I appreciated the communication from Eric and team each step of the way. I would highly recommend Tri-County Contracting to anyone needing a roofing contractor.

I appreciate Tri County contracting workmanship and the piece of mind of annual inspections. Inspector Chris was professional, courteous and flexible in working around my schedule. Thank you

We found and choose Tri-County over the many storm chasers that canvassed our subdivision after a hail event. They were so honest, prompt, and professional from beginning to end. They get gold stars for handling the insurance negotiations without incident and maximizing our claim. Communication from their project manager, Mike Ottow, was superb. We will not hesitate to use them for other projects.
