In Vermont, slate may be a better choice than western red cedar. Clockwise from bottom: Terne-coated steel, clay tile, slate, and red and white cedar. .. One company, ISP Minerals, has developed a whiter roof granule that could be used to make white asphalt shingles that have a solar reflectance as high as 50%.
SOLAR REFLECTANCE TECHNICAL DATA Ecoasis™ Costa is listed with the Cool Roof Rating Council. Ecoasis™ Costa has tested to these radiative property values: Ecoasis Costa Solar Reflective Index: Burlwood: 16, Cedar Cask: 16, Desert. Cool Roof Rating Council ratings are determined for a fixed set of conditions,
How they can be made cool: Buy cool asphalt shingles, which use specially coated granules that provide better solar reflectance. (Coating existing asphalt shingles to make them cool, however, is not normally recommended or approved by shingle manufacturers.) Other roof shingles can be coated at the factory or in the
Highly reflective light color metal roofs do much better with a solar reflectance from 60% to 70%. White paint To evaluate roof coolness a simple value (SRI) called solar reflectance index is used, combining solar reflectance and emittance.
