Product Focus: Roofing Underlayments
Synthetic Underlayment • Alpha Pro Tech
Alpha Pro Tech Engineered Products Inc. has launched its latest synthetic roof underlayment with the addition of REX TECHNO SB: a coated-woven polypropylene fabric that also has a non-woven polypropylene laminated to the top surface. The unique features include a multi-filament strand woven into the product that gives an additional slip-resistant feature. The non-woven fabric is treated so that moisture won’t stand on the top of the surface but will disappear, eliminating the fear of slippage. The rolls come 48 inches wide and 10 squares per roll.

High-Temperature Underlayment • Atlas Roofing
WeatherMaster® TU Ultra SE Peel & Stick SBS Reinforced Underlayment is a high-temperature, self-adhering underlayment designed for tile and slate roofing systems. It’s produced with a blend of modified asphalt and woven polyester. The top surface bonds with foam adhesives used in roof-tile installation and will hold up well under stacked tiles without slippage or damage to the membrane surface. Because safety matters are so important, it’s designed to give roofers excellent traction during installation of a tile or slate roofing system.

Wood-Roofing Underlayment • Benjamin Obdyke
Benjamin Obdyke’s Cedar Breather® protects the beauty and life of wood roofing by providing a space for continuous airflow between the solid roof deck and shingles or shakes. The underlayment product is fire resistant (ASTM E108-tested), provides cushioning during severe hail, works to prevent thermal cupping and warping, and reduces potential rotting. Its patented, three-dimensional design allows continuous airflow between the solid roof deck and shingles, and creates a space to help eliminate excess moisture, allowing the bottom of the singles to dry. Installation doesn’t require any special tools and eliminates the need for furring strips. For more information, visit www.benjaminobdyke.com.
