I had a leak in my roof and Tutu came and had a quick look the day I called him, as I lived nearby. He came by again and fixed it within an hour for me just a couple of days later. No complicated estimates or emergency fees, Tutu made time for me because he saw I was in a bind and he cared. The pricing was incredibly reasonable and he did what I believe to be very high quality work. He took great care to ensure flashing was in place and the leak would not happen again. I felt really good about my choice to go with Sentinel roofing after watching him work. I got a very hard working impression from Tutu and highly recommend him for your roofing needs. Thank you again Tutu for helping give me peace of mind!!!

I am very impressed with Sentinel Roofing work. Tutu was very professional in his job. He was patient to explain the details and answered my questions. I highly recommend this company.

David Smith


Due to someone having access to my account who shouldn't a misrepresentation of Sentinel Roofing happened, who took a yet incomplete situation without the facts. First and foremost, my apologies to Tutu, who I hope was not negatively impacted. Tutu and his team had started working on our roof, when a poor situation occurred with inclement weather. However, regardless of the situation, Tutu and his team have been working tirelessly to repair the damages and get the project done as quickly as possible. Their team has been super positive, and to the best of my knowledge their work is great. Again, to anyone who saw my previous review, disregard it, as it was inaccurate, and to Sentinel Roofing, I am sorry for the false information being sent out.
