About This Product
This medium roofing option makes a statement. Heather Blend weaves together soft purple-gray tones reminiscent of Scottish moorland heather. This unique color adds subtle warmth and visual interest while maintaining broad appeal. Heather Blend coordinates beautifully with soft lavender, gray, and cream exteriors. It adds subtle color interest while remaining neutral enough to complement most color palettes.

Why Choose this product
Key Benefits
- UL 2218 Class 4 impact resistance rating for hail impact protection.
- UL Class A fire resistance (ASTM E108 / UL 790).
- Polymer-modified asphalt formulation designed for flexibility, granule adhesion, and all-weather performance.
- NailTrak provides a 1-1/2" wide nailing area, and instructions emphasize proper placement within the nailing area.
- Wind-resistance warranty: 110 mph for 15 years, with an option to upgrade to 130 mph under specific system requirements.
Considerations
- To obtain the UL 2218 impact rating, CertainTeed notes Landmark ClimateFlex must be installed over a clean deck (no roof-overs).
- Do not apply below a 2:12 slope. Low slopes (2:12 to below 4:12) require full-deck waterproofing underlayment (WinterGuard or GRACE VYCOR or equivalent meeting ASTM D1970), with additional requirements noted for Pacific Northwest low-slope installations.
- CertainTeed strongly recommends impact-resistant cap shingles on hips and ridges (e.g., Shadow Ridge ClimateFlex) for a UL 2218 Class 4 roof system; some insurers may require this.
