Atlas Roofing
components and can cause delaminating 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. Delaminating after installation does not justify a warranty
claim.
FASTENERS: Nails must be 11 OR 12 gauge corrosion-resistance 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.
NEW ROOFING APPLICATION (first shingle layer): 4 nails are required per shingle. The nails are to be
located 6 1/16" up from the bottom edge of the shingle, with one nail placed approximately 1" from
each side of the shingle, and the remaining two equally spaced between the two outer nails as
illustrated in the diagram. NAILS MUST BE MINIMUM OF 1-1/4" LONG. See Diagram #3. (See Section
# 13)
RE-ROOFING APPLICATION (second shingle layer): Requires the same nail placement as New
Roofing.
NAIL PLACEMENT IS IMPORTANT FOR WIND RESISTANCE. INCORRECTLY PLACED NAILS WILL VOID
WIND COVERAGE OF WARRANTY.
