Lead failure is the most common cause of persistent roof leaks on medieval, Victorian and post-war properties in Lenham. The clay peg tile period properties in the conservation core and concrete tile post-war development on the town edge found across the historic market square, the conservation area and Harrietsham were predominantly built with lead flashings, valley linings and parapet cappings that are now reaching or past end of service life. North Downs scarp position facing south-west gives one of the most exposed roofing environments in the Maidstone area means accelerated ridge mortar failure from wind exposure and period clay peg tile repairs in the conservation area are the most frequent lead-related repair calls we attend in the area. All our lead work is carried out to BS EN 12588 using the correct code weight for each application.
We carry out all lead work across Lenham: chimney step and apron flashings, valley linings, parapet cappings, soakers, secret gutters and lead flat roof coverings. Code 4 lead for chimney step flashings and aprons, Code 5 for parapets and valley linings on exposed positions, Code 3 for soakers. Every job is dressed properly into joints and pointed to match the existing masonry.
Step and apron flashing at the chimney stack is the most common lead job on medieval, Victorian and post-war properties in Lenham. Original lead installed 80–100+ years ago becomes brittle, cracks on thermal cycling, and fails at the joints where it hasn't been properly dressed. We re-lead to Code 4 minimum, dress lead into raked mortar joints, and cover with matching pointing. Given the North Downs scarp position facing south-west gives one of the most exposed roofing environments in the Maidstone area in Lenham, chimney flashings should be inspected every 7–10 years — thermal cycling in this area accelerates fatigue compared to more sheltered locations.
Lead valley linings in the internal junctions between roof pitches are a structural element that fails through debris accumulation, thermal cracking and original undersizing. On medieval, Victorian and post-war properties in Lenham the typical failure mode is cracking from repeated thermal cycling — the North Downs scarp position facing south-west gives one of the most exposed roofing environments in the Maidstone area in this area subjects valley lead to a wider temperature range than many parts of the UK. We specify valley linings to a minimum 600mm girth with expansion drips on runs over 1.5 metres, ensuring adequate capacity and correct thermal movement accommodation.
Typical cost: £150 – £1,200+ — Chimney re-lead from £200–£450. Valley re-lead from £300–£700. Parapet work scoped individually.

Code 4 (1.8mm) for chimney step flashings and aprons on Lenham properties. 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, damp patches on chimney breasts or ceilings below, and white staining on the stack are all signs. On medieval, Victorian and post-war Lenham properties we recommend a lead inspection every 7–10 years.
Correctly installed Code 4 lead on a medieval, Victorian and post-war property in Lenham should last 50–80 years. The North Downs scarp position facing south-west gives one of the most exposed roofing environments in the Maidstone area in this area means thermal cycling occurs across a wider temperature range than more sheltered locations, which can reduce service life on exposed positions.
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.
