Commercial

410 OmniSeal™ Base

Mechanically Fastened, Modified Base Sheet

Made with our industry-leading NEX® Polymer Modified (SBS Rubberized) Asphalt, OmniSeal™ Nail Base is our premium, mechanically fastened, modified asphalt sheet for low-slope commercial roofing applications.

System Optionality

OmniSeal™ Nail Base is a modified asphalt sheet that is used as a base sheet to create a 2-3 layer multi-ply system that meets desired performance, cost, and warranty needs.

Mechanically Fastened

OmniSeal™ Nail Base is designed to be attached to the roof deck using capped nails. NEX® polymer modified asphalt seals around the nails to waterproof the penetration.

Fire Rated Roof System

OmniSeal™ Nail Base can be used to cover an existing roof or cover a new roof deck. It is a mandatory component to achieve a Class A fire rating when paired with our 420 OmniSeal™ SA Base/Ply and 436 OmniSeal™ Cap FR Sheet.

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.

Mechanically Fastened

Sheet is applied with specified metal cap nails.

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.
