Abstract
A roofing material is provided. The roofing material comprises a first layer, The first layer comprises 1% to 65% by weight of a first non-styrenic propylene copolymer based on a total weight of the first layer. The first layer comprises 1% to 65% by weight of a second non-styrenic propylene copolymer based on the total weight of the first layer. The first non-styrenic propylene copolymer is different from the second non-styrenic propylene copolymer. The roofing material does not comprise an olefin block copolymer. Other roofing materials, and related systems and related methods, are provided.
