I just got through putting eternabond tape on my perimeter roof seams and around my vents. In researching the eternabond I ran across a post (don't remember what forum) by a person who had built a collar for his A/C using 1X4 lumber and sealing it with eternabond tape. After applying the eternabond on my seams I feel comfortable this would work.
My plan right now is to use 1X2 around the A/C opening and attached to the roof with 3m 4000 adhesive sealant. The eternabond tape would then be used to seal the wood providing additional bonding plus a smooth surface for the gasket. The narrow collar would allow all the drain holes to be open.
To support the front of the A/C unit there is an existing piece of foam near the front of the unit. The A/C is now not setting on the roof except at the gasket and the piece foam in front and maybe a small piece of foam at the back. I plan to put another piece of 1X2 attached like the collar for the front piece of foam to ride on.
There is a smaller piece of foam for the back of the unit I may have to deal with like the front. I will see when I get there.
The gasket kit I bought had the opening gasket, the large piece of foam for the front support and a small piece of support foam for the rear.
