To clarify my situation...I am spliting the general contracting with by builder and unfortunately the roofer was hired by me.He is paid and long gone by now.
I caught him not putting felt on the small roof over my porch and made him tear it off, felt it and put on new shingles. I have pictures of the main roof with felt (including the section now without)just before he started shingling it. This is why I was so surprized when the shingles blew off but no felt was under them. Maybe the row of felt blew off before he laid down the shingles and he just was to lazy to put it back on.
