Facility managers can achieve project goals for fire resistance and solar reflectance more easily with CertainTeed® Presidio® Metal Roofing, according to the latest editions of industry performance test standards. Introduced in 2015, this line of steel roofing products blends the look of classic roofing materials with the wind/hail resistance and solar reflectance of metal roofing. The line is suitable for light commercial and multi-family steep slope applications.
New fire rating requirements issued for Class A and B fire ratings by UL 790, the industry standard for fire-resistant roofing, make it easier for facilities to achieve higher fire ratings with Presidio. Specifiers now can achieve Class A fire rating with Presidio by using a fire resistant rated rolled roofing underlayment as the bottom layer placed over roof sheathing (a structural panel is no longer needed). Also, the metal roofing products now earn a Class B fire rating when paired with any standard CertainTeed roofing underlayment.
In regards to solar reflectance, seven colors from the Presidio roofing product line have recently been listed for solar reflectance and thermal emittance by the Cool Roof Rating Council (CRRC). Presidio Tile colors English Toffee, Nutmeg, Speckled Bronze, and Terra Cotta, as well as Presidio Shake colors Ash, Sand Dune, and Weathered Wood are listed by CRRC with initial solar reflectance values ranging from 0.26 to 0.34.

Each Presidio panel has overlaps that conceal the joints and create a seamless appearance. Presidio Tile conveys the Mediterranean style traditional clay, but weighs less. Presidio Shake is pre-weathered, aged and distressed to recreate the look of wood. Lastly, Presidio Slate feature a stone appearance in a lightweight, recyclable material.
