Does RhinoRoof® underlayment qualify to the Secondary Water Resistance (SWR) discount on a Florida Wind Mitigation (OIR-B1-1802) inspection?

Monday, September 28, 2020

Owens Corning’s RhinoRoof® synthetic roofing underlayment is a sturdier and more tear-resistant underlayment than regular asphalt roofing paper, but it is not rated as a Secondary Water Resistant (SWR) membrane for a discount on your wind mitigation inspection report. An SWR is a "self-adhered and self-sealing modified bitumen roofing underlayment" such as Grace Ice and Water Shield or Certainteed WinterGuard.
