Cephalo group spent time to demonstrate how the product works and what is the best selection to you. The price may not be the lowest among the others but it is reasonable, and it was all worthy. Their team is very professional, good workmanship and thorough. They didn’t open my roof and went for other job. They committed on schedule and completion and the satisfacation. It was really a flawless experience. Cephalo followed up 3 months later after the strong windy weather and checked for any problem, which was none. I have hired several contractors in the past, Cephalo is the best. I highly recommend this roofing company.
