The roof eave assembly bears on a concrete masonry unit wall secured with a wood sill plate and three-eighths-inch hook anchor bolts. Wood trusses frame into the roof structure, reinforced with a three-quarter-inch plywood stiffener fastened to the truss rafter and two-by-four wood stud framing. Plywood roof sheathing and self-adhering sheet underlayment support slate shingles terminating with a stainless steel metal flashing and drip edge. Custom-ripped two-by wood blocking and a synthetic wood cant form the eave overhang, finished with high-density exterior foam molding. A fiber cement soffit incorporates a continuous air vent stopped fourteen inches from the edge of the run and covered with a metal bug screen over hat channels and treated plywood.
