Dr. Roof replaced a small flat roof over our front porch, approx 9' x 9'. We already had a carpenter to do the plywood base so just needed the roof membrane and underlay installed. We had a lot of trouble finding a roofing company to do this for a reasonable price, the large companies won't come out for less than a few thousand. Dr. Roof quoted a fair price and also pointed out that another company was quoting us for an additional insulation layer that isn't needed over an outside space. We were very happy with the price and the work, which was done quickly and professionally.
