I have a low slope 1:12 on the back of my house. The roof is Dibiten (if I recall the name correctly) It is torch bonded and has worked for 22 years. It has no granules. The deck is plywood. I need to have the Dibiten replaced. One roofer wants to use Bakor 1 ply, with a sticky back after stripping the existing roof. Is this product suitable and can it be removed in the future or does it adhere to well to the plywood? The Bakor website does not seem to have any application information for this product. Another contractor wants to put a one ply torch down with granules on the existing roof without stripping it. I am concerned with the additional weight as the plywood is rather thin.
