What Are CertainTeed Landmark Shingles?
CertainTeed Landmark shingles explained: construction, wind and algae warranties, and whether they hold up to Texas Panhandle weather.

CertainTeed Landmark shingles are a laminated architectural asphalt shingle built with a dual-layer fiberglass design that gives them a dimensional, shadow-line look instead of the flat profile of older 3-tab shingles. They're one of the most widely installed shingle lines in the country, and for good reason: the extra layer means more mass and durability per square than a basic 3-tab, without pushing into premium-tier pricing.
What's Actually in a Landmark Shingle
The dual-layer construction is the core of what makes Landmark different from entry-level shingles. Two fiberglass-reinforced layers are laminated together, which adds both visual depth and a meaningful bump in impact and wind resistance compared to single-layer shingles. Each shingle carries an Underwriters Laboratories Class A fire rating, and CertainTeed's NailTrak nailing-zone technology marks exactly where fasteners should go, which cuts down on installation errors that cause premature failures.

Standard Landmark shingles come with a lifetime limited transferable warranty, a 25-year StreakFighter algae-resistance warranty using copper-infused granules to fight black streaking, and a 15-year 110 mph wind-resistance warranty (upgradable to 130 mph). CertainTeed also makes Landmark IR, a Class 4 impact-resistant variant built for hail-prone regions, and Landmark Pro/Premium tiers with heavier shingles and 30-year algae warranties.
How to Decide If Landmark Is the Right Fit
For most homeowners replacing a standard asphalt roof, Landmark is a solid mid-tier choice: dimensional appearance, real wind and algae warranties, and a manufacturer track record that's been around for decades. Where it's worth stepping up:
- Hail-prone areas — look at Landmark IR (Class 4 impact rating) instead of the standard line
- High-wind exposure — the 130 mph upgrade or a jump to Landmark Pro's stronger wind coverage
- Long-term ownership plans — Landmark Pro/Premium's 30-year algae warranty outlasts the standard 25-year coverage

Texas Panhandle Considerations
In a region that sees 8-12 hailstorms a year and has recorded hail up to 4.25 inches in diameter, the standard Landmark line is a reasonable choice for a roof with average hail exposure, but Landmark IR's Class 4 rating is worth the upgrade conversation on any roof going up in the Amarillo area. Whichever tier you choose, the shingle is only as good as the installation underneath it — NailTrak marks the zones, but a crew still has to hit them consistently across every course.

Frequently Asked Questions
Is Landmark a laminated or 3-tab shingle?
Landmark is a laminated architectural shingle — two layers bonded together for a dimensional, shadow-line look, not a flat 3-tab. That two-layer construction is also what gives it more impact resistance than a single-layer shingle.
Does Landmark come in an impact-resistant version?
Yes. CertainTeed offers Landmark IR with a Class 4 impact rating, built specifically for hail-prone regions. Many Texas insurers offer premium discounts for Class 4 roofing.
How long does the wind warranty last?
Standard Landmark shingles carry a 15-year, 110 mph wind-resistance warranty, with an upgrade available to 130 mph. Higher-tier lines like Landmark Pro and Landmark Premium extend wind coverage further.
What's the difference between Landmark and Landmark Pro?
Landmark Pro sits a step up in the lineup with a heavier shingle, a 30-year StreakFighter algae warranty instead of 25, and stronger wind coverage. Both use the same NailTrak nailing-zone technology and CertaSeal adhesive.
