I have had a guy come out and said he can repair the damaged areas of my roof instead of puttin gon a whole new roof. I sold my house and there are some problems with the roof, but I never had any leaks. The home inpector said to the buyer that a roof is needed. But the other roofer said no, we can repair the old one, replace all the bad wood,etc and we will be fine. The other 2 roofing company's want to put on a roof. It is not cost effective for me for the sale of the house.
