Valley lead on Formby's multi-valley Edwardian rooflines carries the combined load of pine needle debris accumulation and standard rainfall — the debris mat that forms in valleys holds moisture against the lead for extended periods after rain, accelerating the pitting that precedes through-failure.
Valley lead on Formby's multi-valley Edwardian rooflines carries the combined load of pine needle debris accumulation and standard rainfall — the debris mat that forms in valleys holds moisture against the lead for extended periods after rain, accelerating the pitting that precedes through-failure.
Pine needle accumulation in valleys at Formby means valley lead condition should be assessed at every autumn maintenance visit — the debris mat conceals early-stage pitting that is visible only when the valley is cleared.
Grade-4 lead throughout. Annual autumn valley clear recommended on pine-belt properties. Combined valley clear and lead assessment at each visit.

“Three valleys on a Formby Edwardian — grade-4 lead, correctly dressed. They recommended the autumn valley clear to protect the new lead.”
“Chimney lead had been patched with sealant twice previously. Full replacement, no sealant. The correct approach.”
“Combined valley clear and lead assessment. The debris had concealed a pinhole failure in one section — caught early.”
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.
