how Can EPDM be bonded directly over rolled roofing?
im doing an addition to my house and im going to have epdm roofing installed (im installing it actually), the other half of my house has rolled roofing, the epdm company tells me i cant bond epdm roofing to rolled roofing with the oils, so is there anyway i can bond the 2 together?

sikaflex (polyurethane sealant) would do it. suggest you call sika and discuss with their technical people to be 100 % sure.

Manufacture recommendations is for a reason. The over all reliability of the product. Bonding it directly to roll roofing….NO! You can apply a fiber board over the roll roofing then apply the EPDM, but then I would suggest to remove the roll roofing to keep the extra weight off the roof.
I would go on to suggest to get rid off all the roll roofing. It is an old school product that is not dependable and repairing it normally helps “for the moment” but with all the seams you just shift problems from one spot to another.
EPDM is a superb product and very durable and choice of many contractors doing flat roofs today.
