at intermediate supports. Cut openings in the plywood to provide the required ventilation area and install screening. Butt the exterior finish to the underside of the soffit. Add a fascia board to the ends of the trusses or rafters and apply wood or prefinished metal fascia extending about 12 mm (1⁄2 in.) below the soffit to form a drip edge.
Special trim pieces are made for metal and vinyl soffit materials to provide support at the wall and at the fascia. For plywood soffits, nail a 19 × 19 mm (1 × 1 in. nominal) strip on top of the sheathing along the wall. This strip supports the inner ends of the blocking and edges of the soffit covering.
