Our revolutionary low-profile Micro Weave® Core
(which is the heart of the shingle) is exclusive
to GAF-Elk. It allows us to eliminate excess
filler weight while leaving 100% of the
protective asphalt in—especially where it
counts: on the weathering (top) layer of the
shingle. The result is a slightly lower weight
shingle with advanced protection.
Our long history of innovation since 1886 is
just one reason why we’re now North America’s
largest roofing manufacturer. For example, we
believe that we are the only shingle
manufacturer who's shingles pass both of two
toughest wind tests in the industry!* It's also
why GAF-Elk is the best and safest choice for
protecting your most valuable asset—your home.
*For your protection, all GAF-Elk shingles
produced starting 1/1/10 meet ASTM D3161 Class F
(110 mph) and ASTM D7158 Class H (150 mph) wind
tests .A review of available competititve
information suggests that we may be the only manufacturer
100% of whose shingles have passed these
critical tests. Why accept anything less for
your home?
