Specialist lead flashings, valleys and chimney work. Lead Sheet Association standards. Covering all SO22 postcodes including Winchester, Badger Farm, Harestock.
Winchester's housing stock is uniquely diverse — Georgian and Victorian terraces and townhouses in the city centre, large Edwardian detacheds in the St Cross and St Giles Hill area, and extensive 1960s to 1980s suburban estates on the city fringes at Badger Farm, Harestock and Weeke. The historic city centre properties on Jewry Street, The Broadway and Canon Street have some of the oldest inhabited roofing in Hampshire.
Our leadwork service covers all of SO22 — free surveys, honest assessments and no call-out fees. Call 0238 184 9628 for same-week availability across Winchester.

Request Free QuoteLead flashing failures in Winchester concentrate around three specific conditions: thermal movement cracking where flashing has been fixed too tightly, failed mortar pointing that secures step flashings to the brick course, and in coastal-influenced areas like Winchester, accelerated oxidation of the lead surface in salt air. The result in all three cases is the same — a pathway for water to enter the junction between roof and wall. We address the root cause rather than applying mastic over the symptom.
The correct lead code depends on the application. Code 4 for step flashings and soakers at chimney stacks and abutments. Code 5 for back gutter flashings, valley linings and bay roof work. Code 6 and above for parapet gutters and flat roof sections. We specify correctly for each application — using undersized lead in a high-rainfall environment like Winchester is a false economy that leads to early failure.
In Winchester's chalk downland valley — drier than coastal areas, sharper frost cycles, the Itchen adding riverside humidity, exposed lead surfaces benefit from periodic patination oil treatment — particularly on south and west-facing sections. Patination oil maintains the protective oxide layer that develops on lead surfaces, suppressing the white lead carbonate staining that appears when the oxide layer is disrupted. It is not a structural treatment but extends the service life of flashings on exposed positions.
"Lead valley on our Winchester property had failed — water was coming in at the junction. Replaced properly in the correct code. Clean, correct work done by someone who knows what they are doing."
"Chimney flashing was mastic over the original lead — a previous roofer's bodge. They removed the mastic, stripped and relaid in proper dressed lead. The difference in quality was obvious."
"Bay roof lead had split at the drip edge. Relaid correctly with new upstand. Clean work, correct specification, sensible price."
Lead flashings in Winchester 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 chalk downland valley — drier than coastal areas, sharper frost cycles, accelerated oxidation of the lead surface. On waterfront and exposed properties, the higher salt concentration in Winchester 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 Winchester property exposed to chalk downland valley — drier than coastal areas, sharper frost cycles 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 Winchester 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.

Chimney step flashing replacement in Winchester: £250 to £600. Back gutter: £200 to £450. Lead valley replacement per valley: £400 to £1,000. Dormer flashing: £300 to £700. Free no-obligation quotes on all leadwork.
In some cases yes — where the lead itself is sound but the pointing or fixing has failed, re-securing and repointing is appropriate. Where the lead has split, cracked or is significantly undersized, replacement is the correct approach. We assess and advise during the free inspection.
Correctly installed lead flashing lasts 50 to 80 years. The main factors affecting longevity are the lead code used, the quality of the dressing and the fixing detail. Lead work done correctly the first time does not need revisiting for a generation.
