Ok done with all rotten framework repair,installed new osb roofing deck,reattached siding, and window on one side. In order to post pics you have to use some sort of hosting site. Too complicated for me. When romoving all of the old caulk and putty from tpo roof I noticed something in the front were the nosecap attaches. Some of the old putty still has the tape on it. I see this being a part of cause of leaking as well. Before I re-attach nose cap I have another question. At the top of nosecap there was a backing like cardboard in the curved section. Could a piece of thin paneling be used there instead? Armdrag it looks like you used something like that on yours. Once again thanks everyone for your help and suggestions.
