A roofer after he gave me a estimate, I hire to put on my roof...He took off old roof but said the felt is good and need not have to install new felt..He also said everything else like valleys ect ect is good and need not be install...He did install new vents..He but all the new material back in his truck and I gather he took it back and got his money back..My concerns is if the old felt is good was this ok to do I had timberline 30 year shingles put on roof..I am a old woman and very use to getting the shaft when dealing with contractors...I had siding and windows put in and yes I got shafted but I am so use to it...I just concern about my roof was this ok and yes I never got a refund on the material he use...so he pocket that on top of his cost he told me...when I ask about the stuff he did not use the same thing I hear over and over, will we use a extra man to get this on faster or was more then we thought it would cost...I am tire of fighting with it over the years I just give in now....But I like to get good news that felt not that important and my roof will be good....
