Chimney back gutters

The uphill side of a chimney can contain a gutter-like weathering detail where the roof meets the back of the stack. It is often hidden from ordinary ground-level views, making it easy to overlook when attention turns to the visible front flashing.

A leak associated with the chimney does not automatically identify this detail as the cause. It does justify a clear description of the symptoms and an assessment of the relevant construction.

Include what cannot be seen

Tell WWR Roofing which side of the chimney is associated with the internal mark and whether there is any previous repair history. Explain where the roof slopes around the stack if that is known from existing photographs or drawings.

Do not climb above the chimney to inspect the concealed side. Any close examination needs appropriate access, especially where the surface or support is uncertain.

Distinguish debris from a damaged detail

A channel containing debris and one with damaged leadwork may need different work. The assessment should explain the condition found, the route of drainage and any associated defect in the covering or masonry.

If renewal is proposed, establish what surrounding materials must be lifted or disturbed. The scope should include their reinstatement rather than describe only the new metal.

Retain photographs with the repair explanation

A wider image helps locate the detail, while closer photographs can show the finding and completed work. Keep both where available, alongside any remaining recommendations for the chimney.

Our leadwork page provides the enquiry route. The article on chimney leaks and damp explains why the whole stack and its use may need consideration before a repair is chosen.
