"I contacted J Tech about a full roof replacement after I had been ignored by two competitor companies for almost a year. J Tech called me back immediately, scheduled an appointment, and had someone meet with me within a week of contacting them. They did an excellent job of explaining the process of putting on a new roof and the products they would be using. They also answered all of my questions and addressed any concerns I had. Once we signed our contract and paid our down payment, it was about an eight week wait for our new roof. Once they were able to start on my roof, they had the entire project done in a day and cleaned things up so well that the only indication that they had been at our house was the new roof. I plan on using J Tech for any future roofing needs I have and highly recommend them."

"Erie homes very professional from first encounter to finished project. I now have peace of mind knowing my basement is waterproof. Great job!!"

"They showed up at 7am and when I got home at 3 the roof was done. Roof looks great."

"Found Sentri on Angi. Jeanette and Violet were very pleasant and efficient in getting a contractor to me in the time frame needed. The contractor was excellent and the roof looks great! I would definitely work with them again if I had additional projects."

"Galpha was a huge help throughout my entire insurance process. They took the time to explain everything clearly, worked directly with my insurance company, and made sure nothing was missed. The communication was professional, and I always knew what was happening next. The work was done right, on schedule, and without stress. I highly recommend Galpha if you need a contractor who actually knows how to handle insurance claims and stands by their word."
