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 with a blend of algae resistant granules help maintain the aesthetic appearance of your roof by resisting black streaks caused by algae and may reduce the need to clean your roof. Dura-Seal AR shingles include a 5-year AR Warranty.

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.

One of the most critical aspects of a successful roofing project is correct installation. Improper fastener placement is the leading cause of incorrect shingle installation, which can subsequently void the warranty as well as lead to leaks or blow-offs. Malarkey architectural shingles are manufactured with The Zone an industry-leading, patented, common bond nailing area that dramatically improves correct fastener placement.

When solar energy hits a roof surface and is absorbed, it raises the temperature of the shingles. This can lead to additional heat entering a home through the roof and premature aging of asphalt shingles. Legacy Silverwood shingles reflect solar rays, which may reduce the amount of heat entering your home and potentially extend the life of your roof in hot climates.

These shingles have measured radiative property values listed with the Cool Roof Rating Council and can be used to comply with California Energy Code Title 24, Part 6 Cool Roof Requirements.
