Highly recommend! We had our roof done on our house and detached garage. From day 1 they kept us in the loop with scheduling, which I really appreciated. The team arrived early and got the job done in one day. The roof looks great!

We had our roof, windows, and doors done by Keller. Wonderful experiences each time. After a few years, we had a small issue with our window flashing blowing off one of our windows after a very bad storm. Also our son poked a large hole through his window screen.
