Quality Aluminum.   EverFlashing perimeter deck flashing allows for the expansion and contraction of composite decking and helps minimize water intrusion between the skirt board and substructure. The material is used in conjunction with the maker’s 1 1/2-inch ledger flashing, or 2 1/8-inch ledger flashing with Deck2Wall spacers to further protect the deck components from water damage. Available in 10-foot lengths and 11 colors to complement a range of decking products, EverFlashing comes in G185, Galvalume, stainless steel, and color-match aluminum. 800.550.1667. www.everflashing.com.
