CertainTeed Landmark shingles are premium, dual-layered architectural shingles designed for high durability, featuring a 30-year warranty, Class 3 impact resistance, and StreakFighter® technology to prevent algae stains. They are widely considered a top choice for residential roofing, offering superior wind resistance, fire protection, and an aesthetic that mimics wood shake. 

Key Features and Benefits

  • Durability & Construction: Landmark shingles are heavier and thicker than many competitors, offering better long-term protection and wind resistance (up to 110–130 mph).
  • Landmark PRO: An upgraded version, the Landmark PRO offers greater thickness, enhanced durability, and more vibrant “Max Def” color options, earning it the 2025 Good Housekeeping Home Reno Award.
  • Weather Protection: Most Landmark shingles feature a Class 3 UL certification for impact resistance, helping protect against hail.
  • Algae Resistance: The StreakFighter technology utilizes copper-infused granules to prevent black streaks.
  • Installation Technology: Features the NailTrak® system, which provides a wide, clearly defined nailing area for faster and more accurate installation.
  • Energy Efficiency: The Landmark PRO Solaris® option uses cool roof technology to reflect solar heat, reducing cooling costs.
