I hired Roof Doctor to fix leaky skylights in an outdoor overhang. They started leaking again after only 6 weeks. After a number of attempts to reach him, he did come back and do the repair work again. In less than a month, the leaks were back and much more significant than they ever were prior to him "fixing" them. He has not responded to any of my attempts to contact him to try to fix them again or return my money. Inspite of his 5 year, money back, satisfaction guarantee.
Based on my poor experience, I would NOT recommend this company for any roofing work.
