Chimney flashings
Two-part flashings on every chimney abutment: soakers under each course of tile on the flanks, and step flashings cut into a fresh chase in the stack. Front apron and back gutter dressed as separate pieces, all in code 4 or code 5 lead depending on exposure.
Roof valleys
Valley linings between two roof pitches are among the highest-load lead applications on a house. We fit valleys in code 5 lead, in short bays (typically 1.5m or less) with laps and clips, undercloak boards where required, and formed edges rather than field cuts. Alternative: preformed GRP or fibre-cement valleys for lower-budget work.
- Code 5 lead, long-service standard for exposed valleys
- GRP, cost-effective and durable, matched to tile colour
- Fibre-cement, traditional look on period pitched roofs
Dormer aprons and side flashings
Dormer roofs meet the main roof at an apron along the front and stepped side flashings along the cheeks. Both dressed in lead, both fitted to the LSA detail. Where the dormer has a lead-covered flat roof, we form the aprons and back gutter as a continuous sequence for a fully sealed junction.
Abutments and pitched-to-vertical joints
Anywhere a pitched roof meets a vertical wall, extensions, single-storey add-ons, coach houses, needs a proper stepped flashing chased into the wall, not tucked behind render or hidden under a fillet. We take it back to bare masonry, chase properly and finish flush.
Lead-covered dormers, bays and canopies
Small flat areas, dormer tops, bay window canopies, porch flat roofs, take a fully lead-covered finish. We fit in short bays with hollow rolls or wood-cored rolls, drips to gutters, and welted edges. It's the traditional Yorkshire detail on many period city-centre properties.
Residential vs commercial
Domestic lead work is nearly always on pitched roof abutments, valleys and dormers. Commercial lead work extends to parapet cappings, mansard flat sections, and heritage restoration, we handle both, matched to spec and priced fixed.
