Hello, Got a question on making a deck watertight. We have a basement under a deck. I want this to shed water and be weathertight. My intial thought is to start with 2x8 16 o.c. (room is 21 x 10)then cover with 1/2"plywood (please note that overall height of deck is restricted to as little as I can go). On top of the plywood would go to layers of felt (tarpaper) and 45 mil rubber roofing. On top of that I would put 1 1/2 inch T & G styrofoam parallel to the joists with treated 2 x 4 laying flat on each joist and then 5/4 treated decking screwed to the 2x4's. I will slope this 1/8" to the foot on the 10 foot run. This will be next to an existing building with 7 foot of roof draining to the deck on two sides. Is the idea correct and should the rubber be glued to the subfloor.? Is there an better way to cover this area and is the 45 mil roofing heavy enough?

Thanks for the advice.

That should do it with these exceptions,

You don't need the layer of tarpaper under a rubber roof. The EPDM gets glued directly to the plywood sheathing.

And you need 3/4" thick plywood sheathing T&G instead of 1/2" Movement in the 1/2" as it deflects will stress the roofing material.
