just put a new roof on in December and sections have blown off four times now. I am in Brigantine, NJ. and this last wind storm on 3/6/13, blew four large sections off of 40 sq. I was told that the problem was not enough sun to melt the strip. I asked if there was a way to help the process, I suggested heating up the singles with a wide torch similar to the ones we use with shrink wrapping boats.
I was told that I was nuts. I called the factory up and they said the only way they know is to use four dabs of cement under each shingle. That's a lot of work. Anybody know of a way???
