Abstract
The present invention relates to roofing materials for roofs, sidewalls and other exterior surfaces exposed to the weather such as, but not limited to, asphaltic and non-asphaltic roofing materials, wherein metal flakes cover up to 100% of the weathering surface of the roofing materials. The metal flakes may be applied to the surface in striations or bands separated by conventional roofing granules or may be blended with conventional roofing granules. The metal flakes may have antimicrobial potential and may provide resistance to microbial growth to roofing materials when dispersed in or applied thereto. The present invention also relates to methods of making the roofing materials.
