ABSTRACT:
A roofing composition is formed as a shingle or from one or more separate sheets. The roofing composition includes a storage layer with an inert non-growing storage medium to absorb and detain precipitation for gradual release. The roofing composition reduces hydraulic discharge rates to avoid overloading downstream drainage systems.
