Lead Specification for Sovereign Harbour
Lead work on Sovereign Harbour properties must be specified for Eastbourne's coastal salt air. Marine environment — Code 5/6 lead, marine-spec UPVC, stainless fixings throughout. Code 5 minimum on all chimney step and cover flashings (Code 4 is adequate inland but underspecified here), Code 5 or 6 for valley linings and parapet gutters, and patination oil applied to all new lead within 24 hours. Patination oil retards the early oxidation cycle that, unchecked in salt air, produces organic acids that accelerate corrosion significantly.
Correct installation technique matters as much as correct specification. Individual step flashings cut per mortar course — not single-piece over the chimney. Cover flashing turned into a raked mortar joint and wedged at 500mm centres. Valley lead lapped and weighted correctly. All of these details are correct practice that shortcuts produce failures within 10–15 years.
