Modified Asphalt Performance

OmniSeal® Cap FR is constructed with our proprietary Polymer Modified (Rubberized) 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 Polymer Modified (Rubberized) 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.
