I do lots of these decks. Install a good waterproofing sys (Bituthene is one). Install strips of protection material where the sleepers are going to be located. Protection material could be 1/8" APOC board, or maybe 90# Cap Sheet. The sleepers are not fastened, the weight of the decking material will hold it into place. The biggest headache is detailing the railing posts.

What Jim says is absultely right. Have run accross many leaking areas covered by decks in which guys/gals just nailed or screwed through the roof material, when the weight of the deck negated the need for that. And the posts DO require detailed work to seal them up. On those occasions when I've put decks back together on an area I've roofed, I create flashings that the posts sits on and IN. Then the roof can be sealed around the flashing as well. If you know what a "pitch pan" looks like, found on flat roofs, it would resemble that.

And if you think about what it might take down the road to dismantle the deck, it might encourage you you take care of any needed roof repairs NOW.

when you refer to detail work on railing do you mean carpentry or roofing flashing etc .

Detail work I was talking about would be the roofing around the posts.

E.Dodge is right...best is to remove the railing posts and waterproof under them. Avoid sealing the waterproofing to the posts....when this is done, it becomes a maintenance problem in the future....especially if they are peeled logs as the radial cracks keep on growing and need to be re-sealed on a regular basis. If the posts are actually the support columns from below, you will have no choice but to flash up onto them.
