Eaves solution for underlay roof without plywood...

[goahead1978]

Hello

Has anyone installed Halotex RS10 or Tyvek Supro Grid as an under-roofing material without using sheathing underneath? These can supposedly be used without an air gap and without sheathing. My question is how to achieve satisfactory drainage at the bottom because, in some way, you must have a couple of sheathing pieces at the bottom to attach the gutter and also connect tightly against the wall at the bottom where the roof membrane should meet the wall membrane/exterior gypsum and remain sealed.

The fabric should extend completely to the tass end of the truss. The gutter is screwed with a gutter hook for mounting on the fascia board. Nail sparse boards under the high leg in level.

Well, thinking about a solution where you build a false ceiling that is a fabric hanging directly between the rafters without any other substrate, which means that the fabric is a few centimeters lower in the middle of the bay so to speak, as it cannot be hung straight, partly for drainage and partly because there are a number of battens even in the middle which are somewhat thicker than the battens directly over the rafter, as support for the eco-fiber on the inside.
