Owners are definitely doing something right to hire and keep this large group of truly great people. It's a joy when they arrive, work, and always follow up to make sure we're happy. Can't recommend them enough. (We've had our own businesses and know how difficult it is to find a team, and even harder to score with customer service and keeping them!)

They did an outstanding job on our home. Would highly Recommend. ☆☆☆☆☆ Marcus Powers2024-11-25Trustindex verifies that the original source of the review is Google. From the first day a wind storm damaged my roof, Rob with Donahue Roofing showed genuine care about me as a customer and for the immediate needs of my roof to protect the building and repair the damage in a professional and expedient manner. Donahue Roofing was more responsive and concerned about me as a customer than the insurance company I pay to protect my home. Suzanne Moran2024-11-22Trustindex verifies that the original source of the review is Google. Thank you so much for the great customer service that Aaron and Bradley provided. They were prompt at their arrival and efficient with the work they did. Our home will feel more secure as the winter and wind approaches. Hope everyone has a happy holiday season, knowing the comfort and security that your company provides! Jennifer Hewett2024-11-15Trustindex verifies that the original source of the review is Google. I called to have a roof leak repaired. Donahue was great! Within a couple hours I had received a call back, knew who to expect at my door, and the leak was repaired. The efficiency and good communication was appreciated. Tim Roberts2024-08-09Trustindex verifies that the original source of the review is Google.
