Roof specifiers and installers can now achieve project goals in fire resistance and solar reflectance more easily with CertainTeed Presidio Metal Roofing as a result of testing to the latest editions of industry performance test standards. Introduced last year, the line of steel roofing products blends the look of classic roofing materials with the exceptional wind/hail resistance and solar reflectance of metal roofing.
Specifiers now can achieve Class A fire rating with Presidio applied over a layer of a specific fire-resistant roofing membrane product paired with a single layer of select CertainTeed underlayments - a barrier board is no longer needed. Further, the Presidio metal roofing products now earn a Class B fire rating when applied over a single layer of a variety of CertainTeed roofing underlayments.
