{"product_id":"no-30-roofing-felt-paper-fp30","title":"No. 30 Roofing Felt Paper","description":"\u003cp\u003eNo. 30 felt paper is an asphalt-saturated organic or fiberglass mat underlayment used beneath shingles, slate, tile and metal roofing. The heavier No. 30 weight is stiffer and more tear-resistant than No. 15, so it holds up better to foot traffic during installation and to longer exposure while a roof is being dried in.\u003c\/p\u003e\n\u003cp\u003eRolls are laid horizontally from the eave up, lapped so water runs over each course, and fastened with roofing nails or cap nails. Once covered, the felt acts as a secondary water shedding layer and separates the roofing material from the deck.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNo. 30 weight asphalt-saturated felt, heavier and more puncture resistant than No. 15\u003c\/li\u003e\n\u003cli\u003eServes as a secondary water-shedding layer under shingles and other steep-slope roofing\u003c\/li\u003e\n\u003cli\u003eSeparates roofing material from the wood deck, reducing resin staining and telegraphing of deck irregularities\u003c\/li\u003e\n\u003cli\u003eLays flat and holds fasteners well, allowing installation with roofing nails or cap nails\u003c\/li\u003e\n\u003cli\u003eLapped courses run parallel to the eave so water is shed over each successive layer\u003c\/li\u003e\n\u003cli\u003eSupplied in a roll for continuous coverage across the deck\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUnderlayment beneath asphalt shingle roofing\u003c\/li\u003e\n\u003cli\u003eUnderlayment for slate, tile and metal steep-slope roofing\u003c\/li\u003e\n\u003cli\u003eTemporary dry-in of a new or re-roofed deck\u003c\/li\u003e\n\u003cli\u003eReroofing over stripped sheathing\u003c\/li\u003e\n\u003cli\u003eSlip sheet and separation layer over wood roof decks\u003c\/li\u003e\n\u003cli\u003eSheathing paper on wall and deck assemblies where a felt layer is specified\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Roofing Felt Underlayment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight Class:\u003c\/strong\u003e No. 30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Asphalt-saturated felt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Steep-slope roofing underlayment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold By:\u003c\/strong\u003e Roll\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARCH Building Supply","offers":[{"title":"Default Title","offer_id":55048724349267,"sku":"FP30","price":27.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/7743\/4195\/files\/arch-placeholder-coming-soon_a88f4668-1802-47f5-96bf-1b1e8ae7c565.webp?v=1790259797","url":"https:\/\/arch-9365.myshopify.com\/es\/products\/no-30-roofing-felt-paper-fp30","provider":"ARCH","version":"1.0","type":"link"}
