I am installing an EPDM membrane over the exposed first floor of our new home(in the process of being built by us). This will be on the floor over the winter before I begin additional framing. I have put down the membrane and sealed the seams. My question is this: Is there a product that can be used to cover the seams as an additional precaution against leaks? I have heard mixed reviews of the adhesive strength of EPDM seams.
From building boxes and fitting face frames to installing doors and drawers, these techniques could be used for lots of cabinet projects.

Did you use the black goop in a caulking tube they recommend using at seams?
I'm definitely not an expert on EPDM but I used it when building the built in gutters on my house. I was up on my roof yesterday and all of the flat seams were still perfect after 5 years. The only areas of concern were where the seams ran across the width of the gutter and there was a 90 degree bend in the seam, a couple started to open up. I used the black EPDM seam sealer, though it came in a pail and was applied with a brush, rather than from a tube.
I guess I would like to know the type of seam sealer, but even the self adhesive EPDM patches you can pick up at a Menards will last thru atleast a year. I use the patches when performing test cuts on EPDM roofs that will be replaced, but the roofs may not be replaced till the next year. Also, for a longer warranty the larger EPDM manufacturers will call for an addition patch at any seams that run perpendicular to each other and then also if the membrane runs up a parapet at the seams. You might find additional info at NRCA (national roofing contractors Assos)website or like a firestone building products/tech manual/ details.

They have uncured strip flashing comes in 6" and 12" rolls ,it is also self adhereing. Wipe the lap joints with a cleaner and lay down the strip. You can also prime the joint if you're really worried.
If you followed directions to the letter, there shouldn't be a problem. I've installed EPDM roofs since 1984, and as long as I, or my men, have been anal about following directions there have been very few problems.
When problems have arisen, it's generally been because somebody cut corners on prep work, or weather moved in suddenly and forced us to hurry up the aplication process.
That's my only problem with EPDM roofs. They are "fussy" to install, so I avoid jobs that may cause me to hurry up the process. Usually. :-)
