DuoStik™ System

Easy-to-Install, Self-Adhered Roof System

The DuoStik™ System is an easy-to-install, low slope roofing system for roofs greater than 1/4″ to less than 4:12″. It utilizes two key components: Arctic Seal® and 430 OmniSeal® Cap sheet. This system provides a cost-effective solution for the low slope portion of your home or commercial building.

System Simplicity

The DuoStik™ System provide waterproof reliability in a simple, easy-to-install, self-adhered two-ply system. Made with Polymer Modified (Rubberized) Asphalt, both Arctic Seal® and the 430 OmniSeal® Cap sheet deliver unparalleled durability.

Arctic Seal®

Arctic Seal® is a durable, waterproof, self-adhering underlayment made for the areas of the roof most susceptible to leaks. Arctic Seal® can also be used as a high-performance, all-roof underlayment. Made with our proprietary NEX® Polymer Modified Asphalt for extra strength and durability, Arctic Seal® provides an extra layer of leak protection in more critical areas like roof valleys, roof edges, and roof-to-sidewall transitions where rain, snow, and ice are more apt to accumulate.
