Abstract
A roofing product that filters and facilitates rain water collection has a substrate with roofing granules that may be configured to perform a water filtering function. The roofing granules may have a porous composite structure comprising a UV-opaque core and a water filtering layer around the core. The roofing product may include a substrate with a first layer on the substrate. The first layer may have a printed pattern or texture to simulate roofing materials, and a protective layer may be formed on the first layer.
