Question:

HI, I purchased the XTRM PVC Roof. I have the old edpm roof removed. Do I need to do anything special to the roof deck to get good adhesion with the new adhesive? The roof deck still has the old adhesive on the plywood. It seems to be adhered well and not peeling. Just dont want to go thru all the work and mess this up. Will the new adhesive stick well to the old adhesive? They plywood is all in good shape. Thanks

While I know it can be a pain, some patience and a putty knife will go a long way. Finally, to finish the install you'll also need the LaSalle Bristol XTRM RV Roof Installation Kit # 3442703414KIT.
