Roof Leveling Compound Helps Eliminate Ponding Water

GreenSlope is a roof leveling compound that helps eliminate water ponding areas on flat rooftops. The cured material is similar to that of a professional running track or playground surface and can withstand tough climates as well as heavy foot traffic. According to the manufacturer, the product is designed to fill in low areas and bring the roof back to its original slope, directing water toward drainage areas. It is designed for use on EPDM, TPO, PVC, modified bitumen and metal roofs. Made from EPDM, GreenSlope is lightweight, durable, and able to withstand freeze-thaw cycles. Other uses include protecting curbs, filling low areas near drains, establishing walk pads and filling pitch pans.


By using recycled materials, GreenSlope™ offers unique advantages that can help drive contractor service sales by opening new doors with prospective clients. Local governments often award contracts to companies using environmentally-friendly recycled products. Using recycled products often helps facility managers meet stringent environmental requirements. The U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) green-building rating system awards points for environmentally friendly construction features. Additionally, contractors and building owners earn LEED points for using building materials that incorporate recycled content materials. Given ponding water is one of the primary concerns most building owners have about their roofs, GreenSlope™ presents an extraordinary opportunity to drive new service sales.
