Key Benefits

- UL Class A fire resistance (ASTM E108 / UL 790).

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.
