Key Features

Modified Asphalt

Made with proprietary NEX® Polymer Modified Asphalt for exceptional weathering and extra strength, flexibility, and durability to resist damage and last longer.

Multi-ply System

Can be combined with conventional or modified asphalt sheets to create multi-layer redundancy and satisfy performance need, cost, or warranty.

Strong & Durable

Modified asphalt sheets are constructed with a sand and/or polypropylene surface to improve walkability and safety, and an underside of aggressive, asphalt-based adhesive to ensure adhesion. The sheets are reinforced with rubber and plastic polymers on a non-woven fiberglass mat.

 

Combined with other sheets for redundancy, modified asphalt delivers greater tear strength than conventional built-up roofing membranes for extreme, lasting durability. Up to 240 mils thick in a 3-ply system, 6X thicker than common single ply roofing systems.

Waterproof System

Naturally waterproof asphalt, built into a multi-ply system, helps resist water penetration.

Impact Resistant

Class 4 impact-rated when used as a system, the highest rating available from Underwriters Laboratory.

Enhanced Warranty

Enhanced warranties are available when product is used in a complete roofing system of Malarkey shingles and accessories, and installed by a Malarkey Certified Contractor.

Fire Resistance [FR]

Class A fire rated in a system assembly over a combustible or non-combustible deck.

Advanced Adhesion

Among industry’s highest adhesion uplift rating for greater confidence sheet will remain securely in place after installation.
