Specialist lead flashings, valleys and chimney work. All to Lead Sheet Association standards. Covering SO30.
Hedge End's 1980s detacheds have simpler lead requirements than the Victorian stock closer to Southampton — mainly dormer flashings on loft conversions and lead soakers at the junction of bay window roofs. Where lead was original to the build in 1985 to 1995, it is now 30 to 40 years old and approaching replacement age in some cases. We carry out all lead flashing work on Hedge End properties.

Request Free QuoteLead flashings in Hedge End fail through three primary mechanisms: thermal movement cracking where flashing is fixed too tightly without movement provision, failed mortar pointing that secures step flashings to the brick course, and in elevated suburban position south-east of Southampton, accelerated oxidation of the lead surface. On waterfront and exposed properties, the higher salt concentration in Hedge End accelerates surface deterioration faster than inland equivalents. We identify the failure mode during inspection and address the cause rather than patching the symptom with mastic.
Lead code specification is critical to longevity. Code 4 for step flashings and soakers. Code 5 for back gutters, valleys and bay roofs. Code 6 and above for parapet gutters and flat roof sections. We specify the correct code for each application — using undersized lead on a Hedge End property exposed to elevated suburban position south-east of Southampton leads to early failure and repeat calls. All leadwork is carried out to Lead Sheet Association standards.
Mastic sealant applied over failed lead flashings is a temporary patch that lasts 2 to 3 years before failing again. Correctly dressed and fixed lead lasts 50 to 80 years. On any Hedge End property we work on, mastic is not used as a substitute for correct lead work. Where we find previous mastic applications, we strip them out and execute the junction correctly in properly dressed lead.
