Dude. These guys are rockstars. Did my roof and the weather conditions weren’t in anyone’s favor. Very professional and would recommend to anyone. Thanks again guys!

The most hard working and respectful bunch of guys I know. They did an excellent job on my new is beautiful! It is priceless for me as a senior citizen to get my money's worth and be treated fairly. Can't say enough about this company's work and how kind they were ...

On 8/20/2023 Joseph N had this to say:
Nice people but they are not fast roofers by any means. It took them like 2 weeks to do my neighbors roof. The roof looks good but I wouldn’t want guys at my house as long as they were over there. Small house by BP in Seneca.
