I have a EPDM roof on our little camper now but don't want to replace it with EPDM for a few reasons. I am installing new exterior 1 sheathing plywood then using a new to me product called Gaco roof coating which has a good guarantee, here is a link to the roof coating.
I contacted the manufacturers and they told me the plywood would probably soak up some of the coating which is good. My question is: would it be best to prime the plywood before the coating.
Another question is: I will be installing a drip cap/edge also. Would it be best to install the drip cap/edge after the first coat of roofing laying a bead of butyl sealant, then install the cap while the sealant is fresh, or should I install the cap/drip edge on the bare plywood with the butyl sealant then two coats of roof coating over the cap as I coat the plywood?
Would it be to my advantage to use a fiberglass tape over the seams of the plywood or seal the edges with the butyl sealant?
I know this is a bunch of questions and I appreciate any help, thanks.
