Metal standing seam rainscreen assembly on clips over a water-resistive barrier and wall framing at the dormer parapet. A metal perimeter angle diverter set in a compatible adhesive bed incorporates a membrane flashing (FAF-1) lapped onto the parapet. A self-adhered membrane (SAM-1) at the roof edge sits under the standing seam panels and laps under the perimeter angle. R-25 unfaced batt insulation fills the roof cavity, with a 90-degree metal trim piece at the corner and the top of adjacent metal panels positioned beyond the primary plane.
