Friendly , professional and easy to work with. I needed a new roof and selected Dorf to do the repairs after comparing 4 local contractors. They have been in business for many years, second generation roofers. Very honest and low pressure, also the best prices compared to the other estimates we had. They scheduled us quickly and did the removal and replacement of 15 rotted sheets of plywood and got the new roof finished in one day. I highly recommend them. Stay dry..
