Where lead work fails on Shrewsbury properties
The most common leadwork failure points across Shrewsbury’s Victorian and Edwardian stock are chimney stack flashings on north-facing slopes, where thermal movement and persistent damp work the lead away from its mortar chase over time. Lead valley linings on clay plain tile roofs in the Belle Vue conservation area need specific attention — undersized lead in valleys is a widespread historic defect we rectify regularly.
Bay tops and flat lead sections
Bay window lead flats are a defining feature of Edwardian properties in Monkmoor and Copthorne. When the lead is undersized, improperly supported or lacks adequate drips and welts, ponding and eventual failure is inevitable. We install bay tops to Code 4 or Code 5 lead as appropriate, with correct fall, drips and soakers to prevent future movement.
