A strange roofing requirement here, ice & water shield (Grace) etc. must be applied at eaves & extending 6' past the interior wall vertical line.
This is to prevent ice dams (which I won't have, no gutters & 9.7 steel roof pitch)
I believe that this is a bad idea, with my closed cell SPF this will create a double water vapor barrier with 5/8" CDX plywood sheathing trapped in the middle.
Perhaps I will file for a variance on this?
