WHEN SPF IS applied as an integral part of the roofing system, it must be protected against UV radiation. Typically, the required protection is attained through application of an elastomeric, liquid applied, coating system, which will cure to form a water-resistant protective membrane. As, in principle, the SPF surface does not need any moisture protection treatment, an aggregate layer, supported by a tack coat of asphalt, can also function as the UV protection for flat roofs in many climatic conditions. The selection of gravel
