Impact-Resistant Shingles: Are They Worth It in Colorado?

Colorado ranks among the top states for hail damage. If you live in places like Denver, Colorado Springs, Aurora, or Fort Collins, you've likely experienced it firsthand. Impact-resistant shingles (IR shingles) are designed to withstand harsh storms—and for Colorado homeowners, they can be a smart investment.

Here’s what you need to know.

What Are Impact-Resistant Shingles?

Impact-resistant shingles are asphalt shingles that have been reinforced to absorb the force of hail and debris. They’re tested under the UL 2218 standard, which simulates hail impact by dropping steel balls from different heights. Class 4 is the highest rating—this means the shingle didn’t crack after being hit by a 2-inch steel ball dropped from 20 feet.

In Colorado, Class 4 shingles are often recommended. They’re designed to resist hail, protect your roof, and reduce long-term maintenance costs.

Key Benefits of Impact-Resistant Shingles

• Hail Protection
  Class 4 shingles resist hail better than standard shingles. Lab and real-world testing by the Insurance Institute for Business & Home Safety (IBHS) shows Class 4 shingles are less likely to crack, tear, or lose granules after a storm.

• Lower Insurance Premiums
  Many Colorado insurance providers offer policy discounts (up to 20%) for Class 4-rated roofs. Check with your insurer.

• Extended Roof Life
  IR shingles hold up better to UV exposure, wind, and hail. That means fewer repairs and less frequent replacements.

• Code Compliance
  Some counties in Colorado may require Class 4 shingles in new builds or reroofs. This aligns with IRC and IBC code expectations in high-wind or hail-prone areas .

Are Impact-Resistant Shingles Worth the Cost?

Yes—especially in Colorado. They cost more upfront (around $2–$4 per square foot more than regular shingles), but that’s often offset by:

• Lower insurance premiums

• Fewer repairs after hailstorms

• Extended roof lifespan

• Increased resale value

In many cases, a Class 4 roof pays for itself within 5–10 years.

FAQs

What is the best impact-resistant shingle?

Look for asphalt shingles with a Class 4 rating under UL 2218. Top-rated products from brands like Owens Corning, Malarkey, and IKO often feature reinforced fiberglass mats or SBS-modified asphalt for better flexibility and durability.

Can I install Class 4 shingles over my existing roof?

That depends on local code and your roof’s current condition. In most cases, a tear-off is recommended to inspect the decking and install proper underlayment.

Do impact-resistant shingles prevent all hail damage?

No roof is 100% hail-proof. However, IR shingles drastically reduce functional damage and granule loss compared to standard shingles.

How do I know if my roof has Class 4 shingles?

Check the shingle packaging, manufacturer specs, or UL 2218 rating label. You can also contact the contractor who installed your roof.
