RhinoRoof® High-Temp | Owens Corning Roofing

The High-Temp Solution from a brand you trust.

Crews have long trusted RhinoRoof® in asphalt roofing. Now rely on RhinoRoof® High-Temp to help enhance the ability to install metal roofs on time and on budget.

Metal roofs can demand more from an underlayment than asphalt shingles. High heat. Extended install times. Expansion and contraction that can allow moisture intrusion. Your choice of underlayment becomes critical to the project and your reputation. 

RhinoRoof® High-Temp makes it an easy one by combining high-heat resistance, on-the-roof reliability, and lasting strength*^. The rugged durability of RhinoRoof® High-Temp is designed to withstand temperatures up to 240°F†† and provides a continuous barrier to help resist moisture intrusion.
