In my experience, once the membrane is pulled up you're left with a LOT of glue to scrape off, and pulling the old roof off tends to pull chunks of the old underlayment off with it. It's difficult (sometimes impossible) to get the old surface smoothed out enough to be a viable surface for the new membrane. Over the years it's become my standard to lay down new luan and then lay down the new membrane. The result is a very smooth roof, without any question of bubbles or debris underneath that will never allow the new roof to completely glue down...
I'd like to know what others do in these situations, the preferred method for quality repair.
Glad you stood your ground...Even us DIYers know you cant glue a membrane without a smooth substrate...see my thread here
