I have used them to repair flashing on our attached garage and was very happy with their work. In this case, I needed our shed roof replaced. They gave me a fair estimate and a quick installation date. They arrived on time, explained what they needed to do and started. They estimated it would take about 4 hours and they were right. They did not mind if I watched them and answered questions along the way. When the job was done, they did an excellent clean up both outside and inside the shed.
I've used several contractors for various jobs around the house and these folks are highly recommended. I would definitely use them again!
