Lead valleys, flashings, bay roofs and flat lead sections across Portsmouth and the Hampshire coast. Portsmouth's salt air is harder on lead than inland environments — we specify the correct code for the exposure position and use no mild steel clips that corrode alongside it. Conservation area lead work in Old Portsmouth and Southsea is a specialism.
Lead roofing in Portsmouth uses code 5 or 6 lead on exposed coastal positions, not standard code 4. Chimney flashings run £400 to £800, valley lead £180 to £280 per metre. Heritage bossing on period properties. Free survey and written quote — call 0239 307 1334.
Lead is the premium roofing material for complex details — chimney flashings, valley gutters, bay roof coverings, dormer cheeks and parapet gutters. In a coastal environment like Portsmouth, lead outperforms every alternative for longevity and weathertightness when correctly specified and installed. Under-specified lead in a direct coastal position will fail in 20 to 30 years. Correctly specified and installed, the same detail should outlast the building.
The Victorian and Edwardian housing stock across Southsea, Fratton, North End and Old Portsmouth carries a disproportionate amount of leadwork. Chimney stacks with multiple flue pipes, complex valley intersections between rear extension and main roof slopes, bay window flat roofs — all are features standard in pre-1914 construction and now reaching the age where original leadwork needs replacement rather than repair.
Old Portsmouth and parts of Southsea fall within conservation areas where the character of original leadwork must be matched or replicated. We carry out heritage leadwork on these properties and advise on whether planning consent is required for your specific job before quoting.
Lead failure on a chimney, valley or bay roof? We survey, specify the correct code, and quote in writing before starting.

"Bay roof on our Southsea Victorian had failed — original lead completely corroded through. Portsmouth Roofing specified code 5 given the coastal position, replicated the original drip profile. The conservation officer commented positively. Excellent work."
"Lead valley on our Old Portsmouth terrace had been leaking for three years, patched twice by others. Portsmouth Roofing stripped it completely, installed new code 4 lead with proper drips and weirs. First dry winter in four years."
"Chimney re-lead on our Fratton Victorian — step flashings, soakers and back gutter. Explained every stage. Priced fairly and the 10-year guarantee is in writing."
Quality lead roofing on a Portsmouth property should last 60 to 100 years — but coastal salt air can reduce this to 40 to 50 years on direct seafront positions. We specify the correct code of lead for the exposure position, not the minimum standard.
For valleys and flashings on standard Portsmouth properties we use code 4 as a minimum. For direct coastal positions — seafront Southsea, Old Portsmouth, harbour-facing Gosport — we specify code 5. Flat lead roofs use code 6 or 7 depending on area.
Lead valley replacement £400 to £900 depending on length. Chimney re-flashing £400 to £800. Flat lead roof replacement £110 to £180 per m2. Free quotes on all work.
Yes. Old Portsmouth and parts of Southsea have conservation area designations where lead is the specified or preferred material for valleys, flashings and bay roofs. We carry out conservation-quality leadwork.
Sometimes — if the lead sheet is sound but a specific area has cracked or lifted, targeted repair with lead welding or a patch is viable. We assess honestly and will not recommend full replacement where repair is genuinely sufficient.
