Plenty of roofing products now carry a UL 2218 Class 4 impact rating, but they don’t all look, install, or warranty the same. Here are the Class 4 options we recommend most for hail-prone roofs around Charlotte and Lake Norman. GAF comes first, since it’s our primary manufacturer, and CertainTeed and Brava are also offered for the right homes.
Short version
- Best overall: GAF Timberline® AS II, an SBS-modified Class 4 architectural shingle.
- Best premium look + Class 4: GAF Timberline UHDZ® with UltraMat™.
- Best designer Class 4: GAF Grand Sequoia® (shake look) or Camelot® II (slate-inspired).
- Matching an existing CertainTeed roof: CertainTeed’s Class 4 Landmark® option.
- Longest-term composite option: Brava composite slate or shake tile (Class 4).
- UL 2218 Class 4 means the product withstood a 2-inch steel ball dropped from 20 feet without cracking in lab testing.
Why this matters
A standard shingle can crack, bruise, or lose granules in one serious hailstorm, and sometimes the damage shows up as a leak months later instead of the day of the storm. When we inspect storm-damaged roofs across the Lake Norman and Charlotte area, impact rating is one of the first things we check. It’s often part of the conversation about whether a roof needs repair or replacement after a storm.
UL 2218 is the test behind every product on this list. For Class 4, the highest rating, a 2-inch steel ball is dropped from 20 feet onto the same spot twice, and the product must not crack. Ask a contractor about impact rating before color or brand.
The Piedmont gets enough spring and summer thunderstorms that hail is a real concern for homes in Denver, NC and the Lake Norman towns. That’s why impact rating matters more here than in markets that rarely see hail.
What makes the best impact-resistant shingle
Every product on this list is rated UL 2218 Class 4. What separates them is everything around that rating:
- Wind performance: the ASTM D3161/D7158 classifications and the manufacturer’s wind warranty terms.
- Algae resistance: hail-prone Southeast climates are also humid, so algae-resistant granules matter for how the roof looks over time.
- Warranty structure: whether enhanced coverage (including workmanship) is available through a certified installer.
- Look: whether the Class 4 product resembles a standard architectural roof or has a designer profile.
- Local availability: whether Charlotte-area distributors stock it or it has to be special-ordered.

1. GAF Timberline® AS II: best impact-resistant shingle overall
Timberline® AS II (ArmorShield™ II) is made with GAF’s proprietary SBS-modified asphalt, which gives it rubber-like flexibility, and it passes UL 2218 at Class 4. It keeps the look of a typical dimensional shingle roof, plus the same LayerLock® / StrikeZone® installation benefits as Timberline HDZ®.
Pros:
- Class 4 rating on a roof that still looks like a standard architectural roof
- Eligible for GAF enhanced warranties on qualifying systems. Golden Pledge® is available only through Master Elite® contractors like us.
Cons:
- Costs more than standard architectural shingles
- Shorter color list than Timberline HDZ®
Best for: homeowners who want Class 4 protection without changing the look of the roof. Verdict: Buy.
2. GAF Timberline UHDZ® with UltraMat™: best premium look with Class 4
Timberline UHDZ® is GAF’s premium laminate shingle. It is thicker than HDZ, with a patented Dual Shadow Line. Its UltraMat™ fiberglass mat gets a UL 2218 Class 4 rating on packages labeled that way, and it carries a 30-year StainGuard Plus PRO™ algae warranty.
Pros: Class 4 plus the most dimensional Timberline look, and the longest algae warranty in the Timberline line. Cons: costs more than HDZ, one color collection. Verdict: Buy if looks and impact rating both matter.
3. GAF Grand Sequoia® and Camelot® II: best designer Class 4 options
For a designer look, GAF rates both Grand Sequoia® (oversized wood-shake look) and Camelot® II (slate-inspired) at UL 2218 Class 4. Grand Sequoia® AS is an SBS-modified Class 4 version. Both carry 25-year StainGuard Plus™ algae protection. See our GAF Designer Shingles page.
Verdict: Buy when curb appeal is the priority and you still want a Class 4 rating.
4. CertainTeed Landmark® Class 4: best for matching an existing CertainTeed roof
Campbells Precision Roofing also offers CertainTeed (we hold CertainTeed ShingleMaster PRO credentials). CertainTeed’s impact-resistant Landmark® product is currently marketed as Landmark® ClimateFlex®, and older spec sheets call it Landmark IR. It’s rated UL 2218 Class 4 and is a good fit when you’re adding on or matching an existing CertainTeed roof.
Pros:
- Close visual match to the standard Landmark® profile
- StreakFighter® algae-resistant granules
Cons:
- Class 4 SKU availability varies by distributor
- Enhanced CertainTeed warranties depend on installer credentials and system requirements
Best for: additions or partial work that needs to match existing CertainTeed shingles. Verdict: Buy for continuity.
5. Brava composite roof tile: best long-term, low-upkeep option
We also install Brava as a Brava Authorized Contractor. Brava makes polymer composite tiles in Old World Slate, Cedar Shake, and Spanish Barrel profiles. The color runs through the material instead of sitting on the surface. Per Brava’s published materials, the tiles carry a UL 2218 Class 4 impact rating and a 50-year limited warranty (terms and registration apply). More on our Brava Systems page.
Pros:
- Class 4 composite that won’t split or rot like cedar
- Slate, shake, or tile look without natural slate or clay weight
Cons:
- Highest cost tier on this list
- Requires an installer trained on Brava’s fastening schedules
Best for: homeowners staying long-term who want a premium look with Class 4 protection. Verdict: Buy if the budget fits.
How we ranked these impact-resistant shingles
Everything here carries a UL 2218 Class 4 rating, so the ranking comes down to wind performance, algae resistance, warranty structure through certified installers, how the product looks on the house, and real distributor availability in the Charlotte area.
Which impact-resistant shingle should you choose?
For most homeowners in the Denver, NC and Lake Norman area, GAF Timberline® AS II is the default Class 4 pick for 2026. It gives Class 4 protection on a familiar architectural look and pairs with GAF’s enhanced warranties. Choose Timberline UHDZ® if you want a more premium look, Grand Sequoia® or Camelot® II for designer style, CertainTeed Landmark® Class 4 to match an existing CertainTeed roof, and Brava when you want a composite slate or shake roof for the long haul.
Cost still depends on roof size, pitch, and tear-off scope. Our Charlotte roof replacement cost guide explains what drives the number.

FAQ
What’s the best impact-resistant shingle for hail in 2026?
For most homeowners, GAF Timberline® AS II: SBS-modified, UL 2218 Class 4, on a familiar architectural look. Timberline UHDZ® (UltraMat™ packages), Grand Sequoia®, and Camelot® II are Class 4 GAF alternatives with different looks.
Are Class 4 shingles worth the extra cost?
In a hail-prone area they often are. Class 4 products are tested to resist cracking from impacts that can damage standard shingles. Weigh the extra upfront cost against your storm exposure and how long you plan to stay. Ask your insurance company whether it offers anything for impact-resistant roofs.
Do impact-resistant shingles change anything with my insurance?
That’s a question for your insurance company, not your roofer. Ask your insurance company whether it offers anything for impact-resistant roofs.
Is Timberline® AS II a good choice for Carolina hailstorms?
Yes. It passes UL 2218 Class 4 and can be part of a GAF system eligible for enhanced warranties. No shingle is hail-proof, and GAF’s limited warranty doesn’t cover hail damage.
What’s the difference between Class 3 and Class 4?
Class 4 is the highest UL 2218 rating and uses a 2-inch steel ball dropped from 20 feet. Class 3 uses a smaller ball from a lower height, so it represents less impact energy. For example, Timberline HDZ® is Class 3 and Timberline® AS II is Class 4.
Can composite roofing like Brava outperform asphalt Class 4 shingles?
Brava tiles are also rated Class 4, and because the color runs through the composite, surface scuffs don’t reveal a different color underneath. They cost more and need a Brava-trained installer. Whether they “outperform” asphalt depends on the storm and the install.
Do impact-resistant shingles look different?
Timberline® AS II and CertainTeed’s Class 4 Landmark® look much like standard architectural shingles. Designer Class 4 lines and Brava composites look more like shake or slate.
One last thing
A UL 2218 Class 4 rating is about resisting cracks in a steel-ball lab test. It says nothing about cosmetic granule bruising, and that kind of mark can still show up after a real hailstorm, even on a Class 4 roof. Surface bruising doesn’t necessarily mean the shingle failed. After a storm, we inspect the roof and photo-document what we find, and you stay in charge of any insurance claim. Read our guide to hail damage around Lake Norman.
