Chimney flashings are essential for protecting your chimney from the elements. To ensure maximum protection, it is important to cover the intersections of the chimney and roof and install a damp proof course (DPC). A correctly installed chimney flashing will prevent rain from seeping into the roof and should last for decades.
For generations, lead has been the go-to material for these components. Including front aprons, back gutters, ridge abutments, and DPC trays.
Our products are designed to be easy to install. And provide a durable, high-quality weathering solution that is both sustainable and long-lasting.
