Metal edge

The nailing flange of the metal should be primed on both sides with D-41 primer. Modified roof cement then applied to the edge, and the metal set in cement. The metal is then stripped in with an 8 inch wide strip of mod bit while torching back of mod bit and metal. ALternately, do as above, then top coat metal and 4 inches out onto roof surface with modified cement. Embed 6 inch asphalt saturated cotton fabric, trowel in and top coat with modified cement. After set, aluminum coat roof and flashing.

It is always good to install a tapered edge right at a drip edge because you end up building up the edge there, and this will cause ponding right behind the build up. This requires covering the roof with 1.5 inch rigid insulation and a mechanically fastened G2 Base sheet though, which costs more.
