Roof deck membrane?

[Lipets]

designing a home and speaking to an architect about a roof deck I said I intend to use Edpm membrane over plywood, then put sleepers with wood deck as the finished deck floor.
He tells me that that membrane with wood deck over will not pass code it must be "treadable" or walkable membrane.

Ever hear anything like that?

Sounds wrong....and that has nothing to do with walking on it.

Sounds wrong or is wrong?
p.s. I like the previous avatar better.

If I understand the situation....he wants to put down EPDM roofing material over plywood and then nail down sleepers for deck boards. That is certain to leak.

Now if I misunderstood the situation and the sleepers are floating with deck boards that is still an off brand use for EPDM which will not last a long time if the roof deck gets much use. Beyond that is trapping water and debris.

The avatar change from a caveman with a stone tablet....well I don't want people too get the wrong idea about me and think that I am a stern sort.

I was planning to have the sleepers floating, not sure why that would be off brand, please elaborate that point.

If anyone wants to put forth another system I'm all ears

Have you checked the manufactiurers installation requirements to see if that’s an allowed design?

Make sure the sleepers are perpendicular to the slope so they don't trap water. Put strips of membrane below each sleeper so they don't touch the roof membrane. Use seam tapes and self-adhered cover strips for all seams.

That's the way I saw it done many times,

Agree

Parallel to the pitch. Perpendicular would trap water.

I suppose that my reluctance stems from having never seen roofing material used in such a fashion. You have seen it used successfully many times. I wonder about the material warranty which would shed light on whether the proposed use is viable.
