New IBHS testing rates 24 shingles for hail resistance. See which brands scored highest, which failed, and what it means for your Texas roof.
Texas homeowners pay premium prices for impact-resistant shingles -- often $2,000-$4,000 more than standard options. The promise? Protection against the state's brutal hail seasons. The reality? New independent testing shows not all "Class 4" shingles deliver on that promise.
The Insurance Institute for Business & Home Safety (IBHS) just released their most comprehensive shingle ratings ever, testing 24 products representing 95% of the market. The results reveal a wide performance gap -- and some popular brands fell short.
Here's what the data shows, and what it means for your next roof.
The Full 2025 IBHS Rankings
IBHS is funded by the insurance industry with no manufacturer ties. Their testing uses lab-made ice hailstones -- not the steel balls used in standard UL 2218 testing -- providing a more realistic measure of how shingles perform in actual storms.
Products are rated across three damage categories:
- D/R (Dents & Ridges) -- Structural damage that can compromise weatherproofing
- T (Tears) -- Shingle integrity failure exposing underlayment
- GL (Granule Loss) -- Protective coating stripped away, accelerating aging
Scores range from 0-10, with 6+ rated "Good" and 9+ rated "Excellent."
Top Performers (Score 7.0+)
| Rank | Product | Brand | Overall |
|---|---|---|---|
| 1 | Grand Sequoia Designer Lifetime | GAF | 8.0 |
| 1 | TruDefinition Duration | Owens Corning | 8.0 |
| 3 | Timberline AS II ArmorShield SBS | GAF | 7.9 |
| 4 | Legacy Scotchgard Protector | Malarkey | 7.8 |
| 5 | Northgate ClimateFlex | CertainTeed | 7.7 |
Marginal Performers (Score 5.2-5.8) -- NOT Recommended for Hail-Prone Areas
| Product | Brand | Overall |
|---|---|---|
| StormFighter Flex4 | TAMKO | 5.8 |
| Dynasty with Armour Zone | IKO | 5.7 |
| Nordic with Armour Zone | IKO | 5.6 |
| Titan XT Premium Architectural | TAMKO | 5.4 |
| Vista AR | Malarkey | 5.2 |
Key finding: No product achieved "Excellent" (9+) overall. Even the top-rated shingles have vulnerabilities in at least one category. This is why installation quality and overall roof system design matter as much as shingle selection.
Why This Matters for Texas Homeowners
Texas isn't just another hail market -- it's THE hail market. According to IBHS data, Texas accounts for 43% of all impact-resistant shingles sold nationally. The state experiences both the highest frequency of hail AND the largest hailstones in the country.
This creates a unique situation: Texas homeowners are the biggest buyers of impact-resistant shingles, but many are getting products that underperform in exactly the conditions they're designed for.
The Real Cost of Choosing Wrong
Here's what makes this data urgent: Texas insurers are increasingly switching from flat deductibles to percentage-based deductibles for hail and wind events.
Instead of a $1,000 deductible, you might face 1-2% of your home's value. For a $400,000 home, that's $4,000-$8,000 out of pocket after every hail event.
If your "impact-resistant" shingles fail after a moderate hail event, you're covering that cost yourself. Choosing a shingle that scored 5.4 instead of 8.0 isn't just a spec difference -- it's potentially thousands of dollars when the next storm hits.
The Class 4 Myth
Here's the critical disconnect most Texas homeowners don't understand: UL 2218 Class 4 certification is not the same as IBHS testing.
Class 4 uses a steel ball drop test. IBHS uses realistic ice hailstones that behave like actual hail -- they shatter, they have irregular shapes, they impact at realistic velocities.
A shingle can pass Class 4 certification but still score "Marginal" on IBHS testing.
What to ask your contractor: Don't just ask "Is this Class 4?" Ask "What's the IBHS score?" and verify at ibhs.org/ImpactRatings

Common questions
Frequently asked
The Insurance Institute for Business & Home Safety rates shingles on a 0-10 scale across three categories: Dents/Ridges, Tears, and Granule Loss. Unlike UL 2218 testing (steel balls), IBHS uses lab-made ice hailstones that replicate real storm conditions. Ratings of 6+ are "Good," 9+ are "Excellent."
