Installation Instructions

8.) FASTENING
Placement of nails is critical to overall performance. High nail placement can result in separation of components
and will cause delamination of the shingles after application. All nails must be driven straight with the heads
flush to the shingle surface, never cutting into the shingle. Nails must not be exposed (visible) on the finished
roof. Delamination after installation does not justify a warranty claim.
FASTENERS: Nails must be 11 OR 12 gauge corrosion-resistant roofing nails with 3/8" minimum head. Nails
must be long enough to penetrate the roof deck 3/4" or if the deck is less than 3/4" thick, the nails should be
long enough to penetrate fully and extend at least 1/8" through the roof deck. Nails may be placed in the sealant
line.
NEW ROOFING APPLICATION (first shingle layer): 4 nails are required per shingle. The nails are to be
located 7" up from the bottom edge of the shingle, with one nail placed approximately 1" from each side of the
