Set it over proper underlayment and integrate it with base flashing so water laps correctly, not behind the metal. On exposed metal roofs, keeping gauge and coating consistent across trim avoids galvanic mismatches and color drift.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eCut metal flashing edges are sharp; wear gloves and eye protection when handling and trimming.\u003c\/em\u003e\u003c\/p\u003e\u003chr\u003e\u003cp\u003e\u003cstrong\u003eOrder the TopShield Zincalume Z-Bar Flashing to close your wall-to-roof transitions cleanly.\u003c\/strong\u003e\u003c\/p\u003e","brand":"TopShield","offers":[{"title":"Default Title","offer_id":53523974750575,"sku":"TOPTS6Z18","price":16.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/3499\/7051\/files\/TOPTS6Z18_0.jpg?v=1790269988","url":"https:\/\/superarbor.io\/products\/topshield-zincalume-z-bar-flashing-mill-finish-3-x-1-x-2-28-gauge-steel","provider":"Super Arbor","version":"1.0","type":"link"}
