Edge Seal™ Added Protection for Metal Roofing

It’s called “edge creep,” and until someone invents a saw that can magically seal cuts in metal roofing as you make them, it’s a problem you can’t afford to ignore.

Now available at HPM, “Edge Seal ” is a proprietary clear, air-dried sealant that protects uncoated metal from corrosion. It was developed by Dura Coat Products, Inc.—the manufacturer providing the 35-year limited warranty on the coating for HPM’s custom metal roofing—and it is applied quickly and easily using a small roller with a short-nap cover. 

Over the past several years, HPM worked with Dura Coat and Steelscape—the manufacturer of our metal roof coil—to perfect the product. Local testing results clearly demonstrate that Edge Seal significantly retards the effects of sulfur dioxide. a compound emitted by the volcano that makes air here even more corrosive. Dura Coat recommends roofing installers apply Edge Seal to all cut edges in the field. Home and business owners are encouraged to follow up every year with regular cleaning of the entire roof system and re-application of the sealant on its edges.
