Raw asphalt must be altered for use in roofing materials, but traditional methods to alter asphalt diminish its natural, rubber-like characteristics. For over 30 years, Malarkey has been engineering and manufacturing a specially formulated blend of polymers and mixing them with raw asphalt at each of our facilities to produce our resilient polymer modified asphalt.

Over the years, Malarkey has continually advanced the development of polymer modified asphalt using new technologies to refine the physical characteristics desired for quality shingle performance. NEX , a blend of asphalt with polymers from repurposed materials, is the result. The use of polymers from repurposed materials is the next step in the ongoing effort from Malarkey to promote sustainable roofing materials while maintaining a high level of quality. This progressive approach improves asphalt flexibility, granule adhesion, cold weather installation, and impact resistance while promoting sustainable product design.

Impacts to a roof from extreme weather can reduce the life of a shingle and lead to water damage. Class 4 shingles undergo UL 2218 testing to withstand impacts from a simulated 2" hail stone hitting a roof at speeds seen in severe storms without sustaining damage. Polymer modified asphalt technology provides superior Class 4 roofing shingle protection, which is the highest rating possible.

Algae growth on a roof can cause black streaks, which can alter the color of your roof and make it appear aged. Shingles featuring Scotchgard Protector utilize 3M copper-containing granules and have been third-party tested for optimal coverage. Shingles featuring Scotchgard Protector help maintain the aesthetic appearance of your roof by resisting black streaks caused by algae and may reduce the need to clean your roof. Includes Malarkeys Limited Lifetime Scotchgard Protector Warranty.

3M Granule Copper Technology

Throughout the day, roofs cycle through periods of hot and cold, causing materials to naturally expand and contract. NEX polymer modified asphalt provides superior flexibility and granule adhesion to better hold granules onto the shingle. When granules stay on the roof, it provides lasting beauty and protection from damaging solar rays.

Driving winds can threaten to lift shingles from your roof if they are not properly secured. Malarkey uses three lines of specially formulated SEBS polymer modified asphalt sealant to help hold shingles in place during high winds. Polymer modified asphalt sealant from Malarkey is engineered with adhesive properties to join the shingles together and cohesive properties to prevent them from separating from the roof. SEBS is also flexible down to 0F (-18C), ensuring the seal remains intact through freeze and thaw cycles.

Shingles with NEX polymer modified asphalt are more resistant to tearing and nail pull-out compared to traditional oxidized asphalts, reducing the risk of shingles blowing off in high winds.

Unique roof structures and cold weather can pose obstacles during installation. NEX polymer modified asphalt technology provides shingles with added flexibility to conform to unique structures. NEX also ensures shingles remain flexible down to 0F (-18C), which is 40 degrees lower than typical standard asphalt shingles.
