Q&A – Which bonding adhesive do I use on a flat roof membrane?

Having read the labels of different bonding adhesives, this Connecticut homeowner wanted to know which one would perform better. 

Chris, a homeowner in Connecticut, was in need of a bonding adhesive for a flat roof membrane over a plywood deck and asked: 

Reading labels informed me that the bonding adhesive for EPDM roofing I chose states that it can be used as a general purpose contact adhesive. Conversely the label on contact states it is good for interior or exterior and can be used for EPDM. Does it matter which one I use on a flat roof membrane over a plywood deck? 

Our resident expert roofer, John Stout with Go Roof Tune Up™, had this to say in response: 

We received your question regarding contact adhesive when applying EPDM Roofing material. There are so many complexities in the manufacture and installation of roofing material, specifically EPDM Roofing. Each manufacturer has exact specifications regarding the application and installation of their product. Our recommendation is to always follow the manufacturer’s direction as closely as possible. This will give you the best product, and may even help if any warranty issue may arise.

Thank you for your question. Your friends at AskARoofer.
