Helps Create a WaterProof Barrier

The self-adhered layer in a roof deck protection system provides a waterproof barrier for vulnerable areas on a roof. Whether the building is faced with wind-driven rain or the potential for ice damming, having a waterproof barrier will help provide protection for a long-lasting roof.

RhinoRoof® Granulated self-adhered underlayment provides that essential waterproof barrier as a second line of defense against water mitigation. RhinoRoof® Granulated combined with a synthetic underlayment, such as RhinoRoof® U20 creates an underlayment system to protect the roof deck from eave to peak.
