Sun
 



 

  

        Barring catastrophic hail, fire or wind, a roof’s major long-term enemy is sunlight, specifically the ultraviolet (UV) light that causes sunburn. UV attacks roofing material, fades the color, and depreciates the natural qualities of the exposed surface.

Ce·DUR and Sun
        
        DURATHON, our patented materials system, and therefore Ce·DUR Shakes, are engineered to not only avoid, but take advantage of this UV segment of the solar spectrum.  The “as shipped” color of the Ce·DUR Shake is adjusted so that as the polyurethane in the Ce·DUR Shake fades from UV energy during the first weeks of exposure, the color changes to the desired and then permanent “Weathered Wood” color.

         Additionally, on warm and sunny summer days when roof temperatures reach 110º F to 120º F, the unique thermoplastic properties of Ce·DUR Shakes allow individual shakes to become flexible enough to "lay down" and conform to the surface below. This "thermal conforming" flexibility keeps the shake from curling away from the roof deck and contributes to the fine wind and hail resistance of the Ce·DUR roof system.
