Lead flashings on Ainsdale's post-war estate housing were often installed at lower specification than Victorian properties — grade-3 lead on 1960s–70s properties is common, and at 40–50 years old in coastal conditions this stock is now systematically failing.
Lead flashings on Ainsdale's post-war estate housing were often installed at lower specification than Victorian properties — grade-3 lead on 1960s–70s properties is common, and at 40–50 years old in coastal conditions this stock is now systematically failing.
Grade-3 lead on Ainsdale estate properties is being replaced with grade-4 as a matter of course — the cost premium is modest and the service life improvement in PR8 coastal humidity is significant.
Grade-4 replacement throughout. No sealant. Assessment of adjacent areas during chimney or valley work.
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.

“Grade-3 lead on our 1969 semi had failed at 42 years. Grade-4 replacement — should last decades more.”
“They removed all the old sealant patches before fitting new lead. Previous contractor's repairs had concealed the extent of the problem.”
“Valley and chimney lead in one visit. Grade-4 throughout, correctly dressed.”
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.
