Modified Asphalt Performance

OmniSeal™ Cap FR is constructed with our proprietary NEX® Polymer Modified Asphalt, reinforced with fiberglass, to create a super strong, durable waterproof roof layer.

Self-Adhered Ease

OmniSeal™ Cap FR is a self-adhered membrane activated by direct sunlight, radiant heat, and applied pressure. Self-adhered roofing eliminates the use of torches and burning asphalt from the installation process.

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.

Self-Adhered

Sheet is self-adhered (adhesive is activated by direct sunlight and radiant heat, and applied with pressure). Self-adhered roofing eliminates potentially dangerous fire hazards and unpleasant odors from the low slope roofing process.

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 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.

Faster Installation & Split Release

Self-adhered membranes have a factory-applied split-release film that protects the adhesive and is removed during installation.

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.
