Metal Roofing Materials and Wall Systems


(Fayetteville, North Carolina, Jan 2008) — Union Corrugating recently launched an advanced synthetic roof underlayment specifically designed for metal roofing installations. REPEL™ offers a superior performing alternative to conventional asphalt-based roofing felts. Constructed of a high-strength woven polypropylene fabric coated on both sides with a specially formulated anti-slip walking surface, REPEL™ offers outstanding nail sealing ability and UV resistance and can be exposed for up to six months. Its light gray color reduces heat gain and provides a cooler working surface.

Traditional roofing felts deteriorate quickly and commonly tear and stick to the underside of metal roofing, adversely effecting roof performance. REPEL™ offers tear resistance that’s 20 times greater than 30# felt and features a 25 year warranty. It also features a Class A fire rating and has received a Notice of Acceptance for use from Miami-Dade, one of the toughest building codes in the country.

REPEL™ was designed with the contractor in mind and is seven times lighter than 30# felt for easy handling. It comes in high coverage 48” wide, 10 square rolls which allows for quick and easy installation with less waste. REPEL’s™ productivity savings allow you to offer customers a better performing underlayment without adding cost to your project.
