This specialised lead flashing creates a channel (gutter) that diverts rainwater around the chimney stack rather than allowing it to pool against the brickwork. Without a properly fitted back gutter, water can penetrate this junction, causing serious structural damage, damp issues, and interior water staining.<\/span><\/p>\n<h3><b>Premium Materials &amp; Craftsmanship<\/b><\/h3>\n<p><span style=\"font-weight: 400\">Our back gutters feature:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">100% recycled Code 4 sheet lead milled to British Standard BS EN 12588<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Precision manufacturing for perfect installation<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Custom sizing for any chimney configuration<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Handcrafted in Cornwall by experienced lead specialists<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Durable construction designed to last decades<\/span><\/li>\n<\/ul>\n<h3><\/h3>\n<h3><b>Ordering Your Custom Back Gutter Flashing<\/b><\/h3>\n<p><span style=\"font-weight: 400\">To ensure a perfect fit for your chimney, we need three key measurements:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400\"><b>Chimney Dimensions:<\/b><span style=\"font-weight: 400\"> The exact width and length of your chimney stack in millimeters.<\/span><\/li>\n<li style=\"font-weight: 400\"><b>Roof Pitch:<\/b><span style=\"font-weight: 400\"> The angle of your roof slope where the chimney sits.
