CertainTeed has replaced their legacy IR (impact-resistant) shingle line with the newer ClimateFlex technology. For homeowners in the Dallas Fort Worth area who deal with hail, heat, and sudden cold snaps, ClimateFlex offers a tougher, more flexible roofing option that still looks great on a home.
What Is CertainTeed ClimateFlex?
ClimateFlex is a polymer-modified asphalt shingle technology. CertainTeed combines traditional roofing asphalt with rubber-like polymers so the shingle stays flexible instead of becoming brittle as it ages. This design helps the shingle resist cracking, weathering, and impact damage over time.
Many ClimateFlex products, such as Landmark ClimateFlex, carry a UL 2218 Class 4 impact-resistance rating, the highest impact rating under that standard.
Why Class 4 Impact-Resistant Shingles Matter in North Texas
North Texas sees frequent hailstorms, high winds, and big temperature swings. A UL 2218 Class 4 rating means the shingle has passed a steel-ball impact test meant to simulate large hailstones. After repeated hits, the shingle cannot show cracking or fracture on the back side.
For Dallas, Garland, Lake Highlands, Plano, Richardson, and surrounding neighborhoods, Class 4 shingles like ClimateFlex can:
- Reduce the chance of leaks after hail and storm events.
- Help your roof last longer between replacements.
- Potentially qualify for an insurance premium discount, depending on your carrier and policy.
If you are early in the process and want to understand how Class 4 shingles fit into overall replacement costs, see our pricing page.
Design, Colors, and Curb Appeal
Upgrading to impact-resistant shingles does not mean settling for a plain, utilitarian roof. ClimateFlex shingles are available in multiple architectural styles and region-friendly colors, including popular blends like Weathered Wood and Moiré Black.
Because the material is more flexible, installers can achieve a clean, refined look on ridges, hips, and valleys. CertainTeed also offers Shadow Ridge ClimateFlex ridge cap shingles to finish off the roof with matching color and added wind resistance.

How ClimateFlex Performs in Texas Weather
Dallas Fort Worth roofs see everything from summer heat to winter cold snaps. ClimateFlex is engineered for all-weather performance:
- Flexible in cold weather, making installation easier and reducing the risk of cracking.
- Strong surface granule adhesion to help the roof keep its color and texture under intense UV exposure.
- Class 4 impact resistance to help resist hail damage over the life of the roof.
That mix of flexibility and durability makes ClimateFlex a good fit for North Texas storm seasons and long, hot summers.
