What are typical colors used for roof surfacing materials?

White and silver (aluminum) are typical colors used for roof surfacing materials, particularly in the context of built-up roofing (BUR) systems. These colors are chosen primarily for their reflective properties, which can help reduce heat buildup in the building during sunny days. Reflective surfaces can lead to cooler building interiors, which in turn can reduce energy costs associated with cooling.

The use of white or silver surfaces also aligns with energy-efficient building practices, as they contribute to better energy management and environmental sustainability. Moreover, these colors can help extend the lifespan of the roofing materials by mitigating thermal expansion and contraction that can lead to material fatigue.

Other colors may not have the same advantages in terms of energy efficiency, and typically darker colors, while common, can absorb more heat, which can be less desirable in warmer climates or for energy savings. Therefore, the preference for white or silver coatings in BUR systems makes sense both for practical application and to comply with energy codes aimed at reducing heat absorption in buildings.
