Draft image: Double Layer Roofing Underlayment (for roof slopes 2:12 - 4:12)

[zupright (Zak Upright)]

I’ve attached a new draft image to preview, before finalizing. I’d like to hear any valuable feedback from the forum. Thanks for your help!

I agree with the fasteners (nails) on the rake drip edge, but I am not a fan of the fasteners at the bottom edge (eave) of the underlayment. Maybe attach the underlayment at the top edge, which gets covered by the next two layers of underlayment.

(Same advice for the graphic you posted on the normal slope roofs)
