CertainTeed’s ClimateFlex technology works at a molecular level to make shingles strong and pliable.

The rubber-like qualities of the ClimateFlex asphalt formula provides each shingle with enhanced hail resistance, cold-weather flexibility, and granule adhesion.

CertainTeed Landmark® ClimateFlex® combines the beauty and dimensionality of wood shake roofing with the durable performance of polymer-modified asphalt. This results in a high-quality designer shingle that offers enhanced resistance to damaging hail, superior surface granule adhesion, and all-weather performance to protect a home year-round in any climate.

The rubberizing aspects of ClimateFlex technology also provides cold-weather-friendly pliability, allowing contractors to handle and install Landmark ClimateFlex in low temperatures that make standard shingles stiff and brittle.
