What is the recommended drop from inside-room subfloor, to outside deck roof surface (the waterproofing layer under the duckboards?)ģ. Are these done as a membrane roof, pitched to scuppers or drains, and clad atop with duckboard walk surfaces?Ģ. If you have done some, and can share some CAD details, I would appreciate it.ġ. I've not done one of these, and wish to learn best practice for detailing and building.
As can be seen, the deck in the roof cutout is presently the same elevation as the subfloor of the second floor.
One of those dormer porches that needs to be designed to drain like a deck built on a flat roof.
Materials, walk surface, drop from inside subfloor, pitch to drain or scuppers, etc., etc.Ī design is to include a small deck outside a half-story up bedroom. Wondering how best to detail the deck floor.
