My parents roof leaked for over 15 years, had two other companies come out and do work on it, one actually replaced the roof, and we still had leaks. Sky came and put a new roof on last year and we have not had a leak since. The workmanship was incredible, we have a difficult roof in terms of steepness and windows, and they completed the work in a couple of days. When the crew left the yard looked like nobody had ever been there to work on the roof and their price was by far the most reasonable of any the companies we got estimates from. I would, and still do, recommend them to anyone.
