Polymer modification makes asphalt more durable, rubber-like,
and super-flexible — to help reduce stress when impacted.
When this material is used to make roofing shingles, it results in
a shingle with excellent flexibility and durability, plus increased
impact resistance.
In fact, in recent testing by the Insurance Institute for Business &
Home Safety (IBHS), they concluded:
Polymer modified IR shingles performed better than traditional
IR shingles (about 20% to 50% improvement) for all four steel
ball impact classes. This was most noticeable at the larger
steel ball sizes (1.50 – 2.0 in.) where the polymer modified
shingles performed at least 40 percent better than the
traditional IR shingles.
So before you decide on which IR shingle to install on your home,
make sure to ask the question: Does it have SBS?

What you should also know about the UL
2218 impact-resistance test:
• Forceful Impact... The test evaluates the shingles’ ability to
withstand high-velocity impact.
• Potential Leaks... When subject to high impact, shingles that
pass this test are more likely to prevent leaks into your home.
• No Warranty Enhancement... Shingle warranties do not
cover hail damage (even for shingles that pass this test ).
RESULTS ON A CLASS 4
SHINGLE... no evidence of
tears, cracks, or ruptures on front
or back of shingle after impact
RESULTS ON A
STANDARD SHINGLE...
it often has ruptures or cracks
visible on the front or back of
shingle immediately after impact
