Ladder the deck bottom-up with 2-4 in. side laps and 4-6 in. end laps, and keep rolls dry until covered. In ice-belt climates, supplement eaves and valleys with an ice-and-water membrane rather than relying on felt alone.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eFelt is slippery when wet or dusty, so wear slip-resistant footwear and keep the deck dry while installing underlayment.\u003c\/em\u003e\u003c\/p\u003e\u003chr\u003e\u003cp\u003e\u003cstrong\u003eOrder Tarco 30# felt underlayment rolls for your next shingle roof and cover 2 squares per roll.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Tarco","offers":[{"title":"Sold per square","offer_id":53522672681327,"sku":"TAR30F","price":14.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/3499\/7051\/files\/ProductImage_TAR15F_7a2dbba0-56c1-4c13-94ac-57590e76669d.jpg?v=1790230487","url":"https:\/\/superarbor.io\/products\/tarco-30-asphalt-felt-roofing-underlayment-roll-36-in-x-72-ft-2-squares-astm-d226-type-ii","provider":"Super Arbor","version":"1.0","type":"link"}
