Grade-4 lead is insufficient for the most exposed Shore Road positions at Banks — we use grade-5 lead on chimney stacks directly facing the combined Irish Sea and Ribble estuary salt loading, where the additional thickness provides meaningful extra protection against salt pitting.
Grade-4 lead is insufficient for the most exposed Shore Road positions at Banks — we use grade-5 lead on chimney stacks directly facing the combined Irish Sea and Ribble estuary salt loading, where the additional thickness provides meaningful extra protection against salt pitting.
The combined coastal exposure at Banks means all lead work is specified with patination oil applied on completion — without patination, fresh lead surface oxides unevenly in the first months and the pitting process begins at the earliest oxide formation points.
Grade-5 lead on exposed Shore Road properties. Grade-4 on more sheltered Banks positions. Patination oil applied on all Banks lead installations.
Every job starts with a free on-roof survey. You receive a written quote specifying exactly what will be done, the materials to be used, and the total cost. No work begins without written acceptance. Call 01704 620 427 to arrange.

“Shore Road chimney — grade-5 lead specified without being asked. They explained the difference and why the extra cost was justified.”
“Patination oil applied on completion. Previous contractors hadn't done this — the lead had oxidised unevenly and started pitting faster.”
“Grade-4 on our more sheltered Banks property. Grade-5 for the Shore Road houses, they explained. Correct differentiation.”
Existing lead is assessed by visual inspection and probe test. We check: surface pitting depth, the presence of through-failures, the condition of mechanical fixings, and whether previous sealant repairs are present. This determines whether targeted repair or full replacement is the correct recommendation.
Old lead is stripped fully. Any sealant residue is removed from the surrounding masonry and tile surfaces before new lead is cut. The mortar joints in the step flashing positions are raked out to the correct depth to receive the lead wedge fixing.
All lead is cut on site to the required profile. Step flashings are individually dressed to follow the tile profile on each course. Soakers are fitted beneath each tile course. Back gutter and apron are correctly lapped with the step flashings. All lead is mechanically wedge-fixed into the raked mortar joint — no adhesive-only fixing. Call 01704 620 427 for a free lead assessment.
Mortar joints are re-pointed with the correct mix for the property — marine mortar on coastal properties, NHL lime on pre-1900 brick. Patination oil is applied to the lead surface on completion to prevent uneven initial oxidation and to inhibit early-stage surface pitting.
Lead flashing work is always preceded by a free on-roof assessment — we access the chimney or valley, probe-test the existing lead, and identify whether targeted repair or full replacement is the correct recommendation. Call 01704 620 427 to arrange. Most assessments are booked within 48–72 hours.
Chimney lead replacement on a standard stack takes one full day. Valley lead replacement depends on valley length — typically half a day to a full day per valley. We provide temporary weatherproofing where the lead is stripped before new lead can be fitted in the same visit.
Patination oil is applied on completion to protect the fresh lead surface during initial oxidation. The mortar pointing around the flashings should be inspected at the next annual roof check — pointing that was sound at installation may need re-dressing after the first frost season as the new mortar cures. Call 01704 620 427 for any post-completion queries.
