Lead is the highest-performance roofing material available — but only when correctly installed. We carry out all lead work across Maidstone to BS EN 12588: chimney flashings, valley linings, parapet cappings and bay tops.
Lead work in Maidstone — flashings, valleys and parapet cappings — uses Code 4–5 lead lasting 50–80 years when correctly installed. Essential for period and conservation-area properties, fully insured and guaranteed. Call 0162 229 6232 for a free lead survey and quote.
Lead failure is the most common cause of persistent roof leaks on Maidstone's Victorian and Edwardian properties. The town has a high concentration of period terraces and semis — around Upper Stone Street, the area north of the High Street, and the inner suburbs of Fant and Boxley Road — where original lead flashings installed 80–120 years ago are now at or beyond end of service life. Lead becomes brittle at low temperatures, cracks on thermal cycling, and is particularly vulnerable where it has not been properly dressed into joints.
Step and apron flashing at the junction between chimney stack and roof slope is the most common lead job we carry out across Maidstone. We re-lead to Code 4 minimum (Code 5 for exposed parapets), dress lead into raked mortar joints, and cover with matching pointing mortar. Work is guaranteed for 10 years.
Lead valley linings in the internal junctions between roof pitches fail through debris accumulation, thermal cracking and original undersizing. We specify valley linings to a minimum 600mm girth with expansion drips on runs over 1.5 metres.
Parapet cappings on Victorian terraces are frequently botched — thermal movement and correct fall requirements make them a specialist job. We specify and install to BS 6915 with adequate expansion joints throughout.
Typical cost: £150 – £1,200+ — Chimney re-lead from £200–£450. Valley re-lead from £300–£700. Parapet work scoped individually.
We inspect the flashings, valleys and cappings at your Maidstone property and identify cracking, lifting or under-coded lead.
You receive a quote naming the lead code weight, girth and dressing detail for each element to be replaced.
We strip the failed lead and re-dress in Code 4 or Code 5 sheet, wedged and pointed into raked joints correctly.
The work is documented with photographs and code weights recorded, backed by our guarantee. Call 0162 229 6232.
Where the mortar has also weathered back, yes, and doing both in one visit shares the access cost. See our chimney repointing page for lime mortar specification and pricing.

“Valley re-lead on a 1930s semi in Coxheath. Original lead cracked and undersized. New 600mm girth valley with proper expansion joints. No more leaks after 3 winters of problems.”
“Parapet capping lead on our Edwardian terrace — a tricky job. Done properly, all expansion joints correct.”
Code 4 (1.8mm) for chimney step flashings and aprons. Code 5 (2.24mm) for parapet cappings and valley linings on exposed positions. All to BS EN 12588.
Visible cracking on the lead surface, gaps between lead and masonry joints, white staining on chimney breasts, and damp ceiling patches below are all signs. On valleys, water tracking sideways under tiles is the key indicator.
Yes. Original Victorian lead is typically well-specified — our replacements match or exceed original code weights. We use traditional methods in conservation areas where required.
Yes. Lead flat roof coverings, parapet cappings and upstand flashings are all within our scope.
Code 4 as a minimum for chimney flashings and Code 5 for valleys and parapet cappings. Under-coded lead fails in 15 to 25 years instead of 50 to 80.
Yes. We work to conservation standards using correct code weights and traditional dressing detail, and we advise on any consent required before starting.
Repeated thermal expansion and contraction fatigues the metal at bends and upstands. Undersized lead without expansion joints cracks fastest, especially on south-facing elevations.
