Unroll it horizontally starting at the eave with proper course overlap, and check the manufacturer's fastening pattern for your exposure. Confirm local code requirements for ice barrier at eaves; Deck Defense may need to be paired with a self-adhered ice and water membrane in those areas.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eSynthetic underlayment can be slippery, especially when wet or dusty; wear appropriate footwear and fall protection while installing.\u003c\/em\u003e\u003c\/p\u003e\u003chr\u003e\u003cp\u003e\u003cstrong\u003eAdd Owens Corning Deck Defense 10-square synthetic underlayment rolls to your shingle job.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Owens Corning","offers":[{"title":"Default Title","offer_id":53531899036015,"sku":"11OCDDEF10","price":296.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/3499\/7051\/files\/Underlayment-Mineral-Surface-SKU_2354819-primary.jpg?v=1790369698","url":"https:\/\/superarbor.io\/products\/owens-corning-deck-defense-synthetic-underlayment-light-gray-10-square-roll","provider":"Super Arbor","version":"1.0","type":"link"}
