F. Install asphalt shingles, beginning at roof’s lower edge, with a starter strip of roll roofing or inverted
asphalt shingles with tabs removed. Fasten asphalt shingles in the desired weather exposure pattern;
use number of fasteners per shingle as recommended by manufacture for regional application. Use
vertical and horizontal chalk lines to ensure straight coursing.
1. Cut and fit asphalt shingles at ridges and edges to provide maximum weather protection. Provide
same weather exposure at ridges as specified for roof. Lap asphalt shingles at ridges to shed water
away from direction of prevailing wind.
2. Use fasteners at ridges of sufficient length to penetrate sheathing as specified.
G. Expansion Provisions: Provide for thermal expansion of exposed sheet metal work. Space movement
joints at maximum of 10 feet with no joints allowed within 24 inches of corner of intersection. Where
lapped or bayonet-type expansion provisions in Work cannot be used or would not be sufficiently
waterproof, form expansion joints of intermeshing hooked flanges, not less than 1 inch deep, filled with
mastic sealant (concealed within joints).
H. Metal Fabrication Seams: Fabricate non-moving seams in aluminum with flat-lock seams and seal with
epoxy seam sealer. Rivet joints for additional strength.
I. Snow Brackets: Install products in strict accordance with manufacturer’s written instructions and
engineered layout charts.
1. Bracket Type D: Install with four 2 inch (51 mm) fasteners directly into sheathing with triangular end
of bracket at eave end of shingle and upper end under shingle in course above.
