Lead Roof Flashing
Lead flashing is used in roofing systems to eliminate leaks at intersections and roof edges. The most common locations for lead roof flashing include Roof joints, valley flashing, chimney flashing, and roof penetrations such as lead roof jacks.
Lead flashing materials are popular particularly in northern climes as they are soft and easy to bend to shape, durable and weather resistant. Lead flashing is also able to accommodate movement between ajoining components.
Lead Chimney Flashing
Lead chimney flashing is particularly well suited to the task, since it easily accommodates any movement caused by the settling of the chimney foundation which is often separate from the main house foundation.
Proper use of lead flashing around chimneys includes two layers. The first called “step flashing”, involves sections of L-shaped lead roof flashing which are lapped up the side of the chimney. Secondly, lead counter flashing is folded down to cover the top of the lead step flashing.
Lead flashing materials produce long lasting roof components, however proper installation requires some experience and skill. Damaged lead roof flashing should be replaced as soon as practical. Lead flashing where shingles meet a wall or other vertical surface may be patched. However, it’s not practical to repair lead flashing in the valley where two roof planes intersect; in this case new lead flashing must be installed.
