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.
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.
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.
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.
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.
Sheets are applied with 1″ diameter plastic cap fasteners.
5 plies, with a synthetic polyolefin reinforcement layer, provides greater tear strength than conventional felt paper underlayment for exceptional durability.
Non-porous monolithic layer of polypropylene helps resist water penetration.
Synthetic membrane is up to 3X lighter than conventional felt paper to help improve product handling and installation speed.
High tear strength and embossed surface design help prevent accidents by providing an anti-skid surface for workers, and keeps roofing materials from sliding.
Incorporating UV resistant polymers, sheet surface can withstand 180 days of direct sunlight, providing a water resistant roof for longer duration installations.
Class A fire rated in a system assembly over a combustible or non-combustible deck.
Made from recyclable polypropylene that be re-used for new product production at the end of its lifecycle.
