Secure Start® Plus

Our Most Popular Underlayment

Secure Start® Plus is a lightweight, synthetic underlayment designed with anti-skid technology, which securely holds the underlayment in place and provides a more walkable surface for greater installation safety.

 

Our most popular underlayment for asphalt shingles, Secure Start® Plus also works well for tile, wood, and metal roofing applications.

 

Underlayment for Shingles, Tile, Wood & Metal Roofs

A new roof requires more than just shingles. It’s a cohesive, coordinated system of 5 parts. In order of installation, they are: 1) ice & water barrier, 2) underlayment, 3) starter shingles, 4) field shingles, and 5) hip & ridge shingles.

 

Underlayment sits under the shingle and provides a vapor barrier covering the entire roof. Malarkey offers three underlayments tailored to asphalt shingle roofs.

 

Secure Start® Plus is our most versatile and popular underlayment.

Three Underlayment Options for Shingles

Moisture Barrier

Made from recyclable polymerized polyolefin, in five unique layers, Secure Start® Plus is a synthetic, water resistant membrane applied to the wood decking of the entire roof as an extra layer of water penetration protection and backup to your shingles.

Versatile & Textured for Safety

Secure Start® Plus is a performance synthetic underlayment that is ideal for asphalt shingles, but versatile to also work for tile, wood, and metal roof applications.

 

An improvement over smooth-surfaced underlayments, Secure Start® Plus has a textured top-side which helps with foot traction for greater walkability, and a safer roof installation.

Installed Second

When installing a complete 5-component system for your new roof, underlayment in installed second, after the ice & water barrier, and prior to the start shingles.

Key Features

Mechanically Fastened

Sheets are applied with 1″ diameter plastic cap fasteners.

Strong & Durable

Safer Installation

High tear strength and embossed surface design help prevent accidents by providing an anti-skid surface for workers, and keeps roofing materials from sliding.

UV Stability

Incorporating UV resistant polymers, sheet surface can withstand 180 days of direct sunlight, providing a water resistant roof for longer duration installations.

Fire Resistance (FR)

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