NorthGate ClimateFlex designer shingles offer the beauty and dimensionality of wood shake roofing in the form of a durable, polymer-modified asphalt. This results in high-quality roofing that offers enhanced resistance to damaging hail and superior surface granule adhesion (compared to standard asphalt shingles), as well as all-weather performance that protects a home year-round in any climate. Cold-Weather Friendly The rubberizing aspects of ClimateFlex technology provide enhanced cold-weather pliability, allowing contractors to handle and install NorthGate ClimateFlex in low temperatures that make standard shingles stiff and brittle. About ClimateFlex Technology ClimateFlex technology blends rubberizing polymers with our premium roofing asphalt to create a tough and flexible product that provides long-lasting performance against the elements.
