The Garland Co. Inc.’s OptiMax polyurethane-modified asphalt-based roof membrane is developed with a process that combines asphalt with polyurethane to create a durable and long-lasting modified membrane. OptiMax becomes increasingly resilient as it ages because, with time, polyurethane molecules are chemically linked with one another. The process was first used in Europe in the paving industry.

When traditional SBS-modified membranes age, the oils within the membrane heat up and “cook out”, causing cracking and eventually leaking. OptiMax utilizes an “active modification” process, which involves chemically reacting the polyurethane modifier to specific molecules within the asphalt. This modification provides enhanced long-term performance characteristics and weatherability.

Its performance is further improved by the fact that minerals are more strongly attracted to the polyurethane in the OptiMax membrane. The result is improved adhesion thus providing UV protection, preventing the likelihood of cracking and leaking issues common in traditional membranes. During advanced surface testing, OptiMax had fewer cracks when compared to traditional asphalt-modified membranes and retained its tensile strength in the face of damaging UV radiation.

“OptiMax has the ability to literally change the face of the roofing industry. This new technology will revolutionize the market and redefine expectations of building owners in terms of performance and protection. OptiMax has been engineered to outperform other commercial roofing products in the industry,” explains Melissa Rus, Garland’s director of research and development.

NorthGate, a designer asphalt roofing shingle offering manufactured by CertainTeed, boasts an SBS-polymer modifier for enhanced weatherability and a rich mixture of surface granules for added aesthetic depth and dimension.

Currently available in the Northwest region of the U.S., NorthGate is designed to endure harsh, cold-weather elements affronting the roof. The shingle’s SBS composition allows it to remain flexible at temperatures as low as 0 F, making it easier to install in cold climates. Plus, the two-piece laminated fiberglass-based shingle meets the requirements of UL 2218 Class 4 for impact resistance.

When tested against a standard asphalt shingle, NorthGate demonstrates a 40 percent improvement in tear strength, a 40 percent improvement in nail pull-through resistance and a 15 percent increase in granule retention.

In addition to its exceptional strength, NorthGate features a rich mixture of surface granules that deliver vibrant, maximum-definition curb appeal and create a dimensional appearance similar to that of natural wood. NorthGate is available in six classic Max Def colors: Burnt Sienna, Granite Gray, Heather Blend, Moire Black, Resawn Shake and Weathered Wood.

The 270 pound-per-square NorthGate comes with a comprehensive lifetime warranty, including a 15-year StreakFighter warranty, 10-year SureStart protection, and 15-year 110 mph wind-resistance warranty. A wind warranty upgrade to 130 mph is available when NorthGate is installed with its companion hip and ridge accessory, NorthGate Ridge and CertainTeed starter shingles.
