Because the hybrid construction serves the ASTM D1970 and D226 roles, verify which listed standard your project requires and lap per the manufacturer's instructions with cap fasteners rated for underlayment. In high-wind or ice-belt applications, check whether your local code calls for self-adhered underlayment at eaves, rakes and valleys and add that product separately.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eUnderlayment surfaces are slippery when wet or dusty; use roof brackets or walkboards and fall protection when installing.\u003c\/em\u003e\u003c\/p\u003e\u003chr\u003e\u003cp\u003e\u003cstrong\u003eGet TRI-BUILT Roof-Proof Hybrid Underlayment 4.5-square rolls for your next roof.\u003c\/strong\u003e\u003c\/p\u003e","brand":"TRI-BUILT","offers":[{"title":"Default Title","offer_id":53529525092719,"sku":"TB-6500-45","price":112.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/3499\/7051\/files\/563017_default_hero.jpg?v=1790350897","url":"https:\/\/superarbor.io\/products\/tri-built-tb-6500-45-tri-built-roof-proof-hybrid-underlayment-roll-4-5-squares-450-sq-ft","provider":"Super Arbor","version":"1.0","type":"link"}
