 Trustindex verifies that the original source of the review is Google. I had a great experience with T. Simpson roofing from start to finish. Terry gave me an honest assessment of my roof and provided a very fair quote. Tiffany was amazing to work with for scheduling and billing. Understanding I was on a short timeline to get my house ready for sale they were able to work me into their busy spring schedule to meet my timeline. The work crews were very efficient and did an amazing job on my new roof and eavestroughs, and they look amazing. I would highly recommend T. Simpson for any roofing needs.

The guys were prompt, professional, and polite. Jordan and crew made sure everything was done neatly and professionally. Would hire again!!

Ed did a great job replacing my metal roof, and Jordan and his crew did a great job replacing my eavestroughs. The workspace was left clean, and any incidental damage was repaired.

 Trustindex verifies that the original source of the review is Google. We had a great experience with T. Simpson to replace our fascia, soffits and gutters back in 2020. I followed up in 2025 with a special request for some matching aluminum and they had it ready for pickup the same day! Great family business.
