Roofs are exposed to the suns rays from sunrise to sunset. Most roofs in North America are asphalt based roofs where the final coating is a thin layer of bitumen, then protected by a layer of coarse mineral aggregate or gravel. The gravel is applied to protect the roof against harmful UV rays, but over time wind will blow off the gravel thus exposing the roof to the elements. The exposed bitumen will dry-out and crack and finally fail, costing you thousands of dollars to replace. The average temperature of a dark roof in Canada can be as high as 230 degs F or 110 degs C. The difference in temperature from day to night can cause thermal movements thus accelerating the degradation of the bitumen
