ROOF TOUGHNESS 101: WHY YOU NEED CLASS 4 IMPACT RESISTANT SHINGLES
How tough does your roof need to be?
First, consider the kind of climate you’re dealing with year-round. Is hail ever an issue? Is it windy where you live? Harsh conditions often signal a need for impact-resistant shingles.
If extreme weather conditions seem even a remote possibility (and considering the effects of climate change, they’re truly a greater threat than ever before, no matter where you live), go for the tough stuff. You need a roofing shingle that has been lab-tested by the roofing manufacturer and is proven to withstand hail and provide reliability in your building envelope. A Class 4 Impact Resistant Shingle will provide these benefits and more, including insurance discounts in some areas.
An SBS-modified shingle is manufactured with special polymers that give it “rubberized” characteristics. The benefits of the SBS-modified formula include a Class 4 Impact Resistance rating (the industry’s highest), superior weatherability, and improved granule adhesion, which make this, arguably, the most durable shingle in the industry. If you live in an area that’s prone to hail, this is the shingle you need.
Impact Tested to Prevent Cracks and Tears
In a Class 4 UL 2218 Impact Resistance test, a 2-inch steel ball is dropped from 20 feet to see if the shingles will fracture. With a regular shingle (most of our competitors’ impact resistant shingles are only Class 3), cracks and ruptures will appear from that kind of impact. With Class 4 shingles, there are no splits or tears.
Proven High Performance: Bends But Won’t Break
In layman’s terms, two-piece laminated fiberglass-based shingles are tougher with a stickier surface than a standard asphalt shingle. If you put side by side with a non-modified asphalt shingle and pressed each against a pipe, you’d see the other shingle break while the class 4 bent back against the pipe. The SBS composition helps keep the shingle from cracking, even in temps as low as 0°F. This is a shingle that was designed to withstand whatever Mother Nature’s throwing at it.
LANDMARK CLIMAFLEX CLASS 4
The latest innovation to CertainTeed’s trusted Landmark® product family, 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.
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.
About CertainTeed Roofing Technology
As a result of our dedication to product improvements and manufacturing excellence, we’ve developed numerous valuable technologies that help contractors and homeowners build better, safer, more comfortable homes. This CertainTeed product features the following roofing technologies:
ClimateFlex® shingle technology combines our durable roofing asphalt with the performance benefits of rubberizing polymers. This results in impact-resistant shingles that offer an industry-leading Class 4 rating for protection against hail damage and hail impact, as well as superior surface granule adhesion and all-weather performance that protects year-round in almost any climate or condition.
QuadraBond technology firmly secures the layers of a shingle together, helping roofs stand up to wind and weather so they maintain their beauty and performance. Featuring an industry-best four points of adhesion, and backed by CertainTeed’s superior manufacturer’s warranty, QuadraBond delivers exceptional quality and reliable strength against shingle delamination.
StreakFighter® technology provides reliable, long-term protection against the unsightly black streaks caused by algae formation. Featuring copper-infused surface granules that possess natural anti-algae properties, StreakFighter works to prevent algae from taking hold on shingles – helping roofs maintain their beauty and color.
CertaSeal is a high-grade adhesive made from a proprietary blend of asphalts and polymers that seals shingles together on the roof to safeguard against wind uplift, shingle blow off, and moisture infiltration. Unlike harder sealants that can dry out and crack over time, it is designed to remain pliable and accommodate the slight structural shifts caused by years of temperature and weather changes.
NailTrak® wide nailing area has helped contractors install our shingles with speed, accuracy, and confidence for more than a decade. NailTrak removes the guesswork with three separately defined lines, presenting a large area to guide nailing and a smaller area for extreme steep-slope applications. Learn more about the NailTrak nailing line.
ClimateFlex® Polymer-Modified Shingle Technology
ClimateFlex technology combines our durable roofing asphalt with the performance benefits of rubberizing polymers. This results in impact-resistant shingles that offer an industry-leading Class 4 rating (UL Classified to UL 2218) for protection against hail damage and hail impact, as well as superior surface granule adhesion and all-weather performance that protects year round in almost any climate or condition.
