Generated explanation

The illustration shows a cutaway perspective of asphalt shingle installation over roof sheathing, with eave protection beneath the lower courses. An alternate starter strip consists of 12+ inch wide roll roofing or shingles installed tab up; the drawing explicitly describes this arrangement as less than ideal but commonly seen. The first shingle row is cemented to the starter strip, and overlapping courses provide a minimum 2-inch headlap. Nail locations are specified relative to shingle edges and cutouts, with a separate spacing annotation for starter-strip nails. Shingles project at least 1/2 inch beyond the sheathing at both the eaves and rake.
