Your roof is worn-out and you’re shopping around for new shingles . You’re comparing impact resistant shingles versus non-impact resistant shingles and you’re wondering if they are worth the additional cost. You know you’ve gotten hit by hail in the past, but they’ve never really caused my damaged, so why bother? Below, we cover what they are, if they’re worth the additional cost, how much more they cost, and what the advantage is.
Short Answer: Yes, impact resistant shingles are worth the additional cost as they are more hail and wind resistant, have better warranties, most insurance companies offer a discount on your premium if you have IR shingles, and most folks find the peace of mind they get with IR shingles worth it.
With impact resistant shingles, most insurance companies give a discount on your premium because the roof is more resistant to hail damage. That discount is often between 15% and 30%. Personally, I use State Farm and they offered me 26% discount on my insurance premium if I purchased IR shingles. Check with your insurance company to see what your discount might be. The real savings on with IR shingles, however, is not having to worry about small hail damaging the roof and you coming up with the deductible.
What Are Impact Resistant Shingles?
When most people talk about impact resistant shingles, they’re referring to impact resistant asphalt shingles. As opposed to stone-coated metal shingles (see below). Impact resistant shingles, also referred to as IR shingles, are roofing shingles manufactured to withstand or resist the impact of objects, such as hail, better than non-IR shingles. Small hail stones won’t damage IR shingles. These shingles are not impact proof, mind you. The point of these is to extend the life of your roof. The average life expectancy of regular, non-impact resistant 3-tab shingles is about 20 years. Impact Resistant shingles, on the other hand, such as Owens Corning’s TruDefinition Duration, should last closer to 30 years.
Not all IR shingles are the same, mind you. For example, compare Owens Corning’s TruDefinition Duration Storm to their Duration Flex. Both of these shingles are impact resistant, but the Flex line has SBS modified asphalt which makes them more pliable and gives them greater flexibility than other shingles. This gives the shingles a rubberizing effect. Hail and other debris will have a greater tendency to bounce off. CertainTeed also has SBS modified asphalt shingles. If you’re looking for the best IR shingle, look for one with SBS.
Who Tests the Shingles?
Underwriters Laboratory tests all sorts of things, including roofing shingles. They basically test products to make sure they perform as expected or advertise. They develop standards, design equipment, uncover potential hazards. Learn more at WikiPedia. Their impact test is called Impact Resistance of Prepared Roof Covering Materials (UL 2218). Consumer Reports also tests roofing shingles, among other products.

Additionally, depending upon the discount your insurance company offers, it might only take 3-4 years to pay off the upgrade to IR shingles.
How Much More Do Impact Resistant Shingles Cost?
Short answer: 50% to 100%, however…
Most homeowners purchase architectural/dimensional shingles. Let’s assume a homeowner has a 2500sf roof. The average architectural shingles would cost them around $8,200. IR shingles, about $12,500. That’s about 50% more. However, don’t forget the potential insurance premium discount mentioned above 🙂
Here along the Colorado Front Range, we get hail storms. Maybe you’ve noticed. According to the National Oceanic and Atmospheric Administration (NOAA), in 2019 there were almost 300 hail storms here in Colorado.
According to the Insurance Information Institute, Colorado ranked #5 in the Top Five States of Major Hail Events.
1/2″ hail stones or less probably won’t damage your roof if it’s in good condition. Larger than this, and you should contact us for a free roof inspection.
The Pros and Cons of Impact Resistant Shingles
IR Shingle Advantages:
The obvious advantage of these shingles is that they are more resistant to impacts, such as from hail, than regular shingles. As a result, they last longer. This means, instead of your replacing your roof every 20 years, you’re replacing it every 30 years or more.
And, if you have IR shingles, if your roof is hit with small hail stones and not damaged, you’re not reporting it to your insurance company and paying your deductible every time.
Most impact resistant shingles also come with other benefits. For example, Owens Corning’s IR shingles are also high-wind resistant and come with a limited lifetime warranty. CertainTeed’s Landmark Climateflex shingles are also fire, wind, and tear resistant.
Of course, the obvious disadvantage of impact resistant shingles is the additional cost. As you’ve read above, this potentially is minor. The advantages of IR shingles outweigh the minor disadvantage.
What About Metal Shingles?
When most people discuss impact resistant shingles, they’re talking about asphalt roofing shingles. If you’re looking for a roofing shingle that’s impact resistant, metal shingles are the most impact resistant. Metal is much more durable than traditional fiberglass asphalt shingles. That’s why they last so much longer – 2 to 3 times longer, in fact. Stone-coated metal shingles initially cost more, however. But, because they last so much longer, they end-up costing less in the long run. Metal shingles are also recyclable in our area, unlike asphalt shingles, which makes them a more eco-friendly option.
The Bottom Line
If you live in Colorado, and if asphalt shingles is what you’re shopping for, you should get impact resistant shingles. In fact, some cities, such as Fort Collins, you can not install a new non-impact resistant roofing product. As you can see, it sometimes doesn’t cost much more than your average architectural/dimensional shingles, yet the benefit is big. If you want the most impact resistant roof, get stone-coated metal shingles. These shingles resemble traditional shingles (or tile or wood shake), but last longer, yet.
