Natural titanium-zinc is the metal a lot of roofers now reach for instead: it cuts and folds cleanly and settles into a soft, even grey that suits period brickwork, slate and stonework.

Go to 1.2mm or 1.5mm for larger panels, exposed areas, or where a stiffer, more forgiving sheet is easier to form.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it replace lead?\u003c\/strong\u003e For flashings, cheeks and small roof details, zinc is widely used as a substitute. It is harder and less malleable than lead, so it is formed with folds and seams rather than dressed into shape, and it is not a like-for-like swap on every detail. Check the specification with your roofer or building control.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill it look silver forever?\u003c\/strong\u003e No. The bright mill finish gradually turns matt grey as a protective patina develops. The supplier quotes 6 to 24 months depending on exposure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use it next to copper or lead?\u003c\/strong\u003e Not without care. Water running from copper can damage zinc, and lead run-off should also be kept away. Keep them separate, or detail so that water does not flow from one onto the other.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need a specialist to install it?\u003c\/strong\u003e For anything beyond a simple flashing, yes. Forming welts and seams and soldering joints are skilled jobs, and a bad seam is where zinc roofs leak.\u003c\/p\u003e\n","brand":"Rubber Roof UK","offers":[{"title":"0.8mm \/ 2000 x 1100mm","offer_id":67521541800127,"sku":"RRUK-ZNSHT-08-2000X1100","price":218.99,"currency_code":"GBP","in_stock":true},{"title":"0.8mm \/ 2500 x 1100mm","offer_id":67521541832895,"sku":"RRUK-ZNSHT-08-2500X1100","price":263.99,"currency_code":"GBP","in_stock":true},{"title":"1.0mm \/ 1600 x 900mm","offer_id":67521541865663,"sku":"RRUK-ZNSHT-10-1600X900","price":186.99,"currency_code":"GBP","in_stock":true},{"title":"1.0mm \/ 2000 x 1100mm","offer_id":67521541898431,"sku":"RRUK-ZNSHT-10-2000X1100","price":263.99,"currency_code":"GBP","in_stock":true},{"title":"1.0mm \/ 2500 x 1100mm","offer_id":67521541931199,"sku":"RRUK-ZNSHT-10-2500X1100","price":319.99,"currency_code":"GBP","in_stock":true},{"title":"1.0mm \/ 3000 x 1100mm","offer_id":67521541963967,"sku":"RRUK-ZNSHT-10-3000X1100","price":375.99,"currency_code":"GBP","in_stock":true},{"title":"1.2mm \/ 1600 x 900mm","offer_id":67521541996735,"sku":"RRUK-ZNSHT-12-1600X900","price":215.99,"currency_code":"GBP","in_stock":true},{"title":"1.2mm \/ 2000 x 1100mm","offer_id":67521542029503,"sku":"RRUK-ZNSHT-12-2000X1100","price":308.99,"currency_code":"GBP","in_stock":true},{"title":"1.2mm \/ 2500 x 1100mm","offer_id":67521542062271,"sku":"RRUK-ZNSHT-12-2500X1100","price":375.99,"currency_code":"GBP","in_stock":true},{"title":"1.2mm \/ 3000 x 1100mm","offer_id":67521542095039,"sku":"RRUK-ZNSHT-12-3000X1100","price":442.99,"currency_code":"GBP","in_stock":true},{"title":"1.5mm \/ 2000 x 1100mm","offer_id":67521542127807,"sku":"RRUK-ZNSHT-15-2000X1100","price":375.99,"currency_code":"GBP","in_stock":true},{"title":"1.5mm \/ 3000 x 1100mm","offer_id":67521542160575,"sku":"RRUK-ZNSHT-15-3000X1100","price":542.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0598\/1804\/9727\/files\/natural-zinc-sheet-dormer-cheek-flashing-clean-seams.jpg?v=1790670427","url":"https:\/\/rubberroofuk.uk\/products\/natural-zinc-roofing-flashing-sheet-en-988-titanium-zinc","provider":"Rubber Roof UK","version":"1.0","type":"link"}
