Failed lead flashings or leaking valleys in Auchterarder? We replace and install code 4 and code 5 lead to correct specification with traditional dressing techniques. Free no-obligation surveys across PH3.
Lead work failures are one of the most common sources of water ingress across Auchterarder's Victorian High Street properties and 1970s bungalow development. The original lead on properties in this area was typically installed at construction or in post-war repair campaigns — much of it is now 50–80 years old and approaching or past the end of its reliable service life. The failure modes vary: apron flashings fatigue-crack at the top edge where they are fixed into masonry, step flashings work open at the laps under thermal cycling, and valley linings develop pinholes or splits at the centre of the run where the water flow is highest.
Ochil Hills fringe elevation with harder frosts and greater wind exposure. In Auchterarder's conditions, lead work on north-facing and exposed elevations deteriorates faster than sheltered Perth city properties of the same age. We specify code 4 lead as a minimum for all Auchterarder flashings — code 3 has insufficient thickness for the thermal cycling and rainfall loading in Perthshire. For valley work and flat roof upstands where the water loading is highest, we specify code 5. All lead is dressed by hand to the masonry profile rather than using mechanical formers.
Lead work inspection is part of every chimney survey and flat roof assessment we carry out. Early identification of fatigue cracking at flashing edges prevents the progressive water ingress that causes ceiling and wall damage. Call 01738 245 298 for a free lead work survey in Auchterarder.

01738 245 298Lead work inspection is the most undervalued preventative maintenance action available to property owners in Perthshire. A professional lead inspection every 10 years identifies fatigue cracking and lifted fixings before they cause internal water damage. The cost of an inspection is a small fraction of the remediation cost once a failed flashing has been admitting water for a full winter season.
Auchterarder's Victorian High Street properties and 1970s bungalows each present specific requirements for this type of work. The Ochil fringe elevation with harder frosts in Auchterarder means materials and specifications must be appropriate for the local conditions. We assess all of this at the free survey stage — the recommendation you receive will be specific to your property and its location in Auchterarder, not a generic quote applied across a wide area.
Lead is graded by thickness: code 4 (1.80mm) is the minimum for chimney and abutment flashings in Perthshire. Code 5 (2.24mm) is required for valley linings and back gutters where water volume and pressure are highest. Code 3 — widely used on pre-1980 properties — is too thin for Scottish thermal cycling conditions and is a replacement priority wherever it is still in place. Specifying code 4 as a minimum is not conservative: it is correct for the exposure conditions.
Lead fails in four ways: fatigue cracking at the fixed top edge from repeated thermal cycling; wedge fixing detachment as mortar deteriorates behind it; lap joint separation on extended valley runs; and surface pinhole formation on undersized code 3 sections. Each failure mode has a different repair or replacement approach. Proper diagnosis requires close inspection — binocular observation from the ground is insufficient for identifying which mode is present and how extensively.
Lead must be installed in sections no longer than 1.5 metres to accommodate thermal expansion and contraction. Longer sections expand and contract as a single unit, concentrating stress at fixings and lap joints in a way that eventually fails both. On older properties where lead was installed in extended runs — a common pre-1970 practice — the characteristic failure is cracking at joints and edges. All our replacement work uses correctly sized sections with appropriate expansion provision.
Code 4 lead correctly installed has a design life of 60–100 years. In exposed Highland Perthshire locations — Crieff, Aberfeldy, high-altitude Kinross-shire — 50–70 years is a realistic expectation. In sheltered Perth city positions, 80+ years is achievable. The limiting factor is almost always fixings and joints, not the lead body itself. A professional inspection every 10 years catches joint deterioration before it becomes an active leak.
“Valley had been leaking at the lower end for two winters. Perth Roofing stripped the old lead, found the original was code 3 undersized, replaced with code 5. No return of the problem through a very wet autumn.”
“Chimney flashings failing at the step joints. Full re-lead in code 4, properly wedged and pointed. Clean professional job. They also flagged the pointing needed attention while they were up — useful to know.”
“Lead on the flat roof extension upstand was lifting at the corners. Replaced with new code 5 lead properly dressed and mechanically fixed. Dry since then.”
Correctly installed code 4 or code 5 lead has a design life of 60–100 years. In the exposed conditions of Highland Perthshire locations like Crieff and Aberfeldy, we estimate 50–70 years. On sheltered Perth city properties, 80+ years is realistic. Failure is usually at fixings and joints rather than in the lead itself.
Lead is graded by thickness: code 4 (1.80mm) is our standard for chimney step and apron flashings. Code 5 (2.24mm) is used for valley linings, back gutters, and flat roof upstands where the water volume and pressure loading is higher. Code 3 is too thin for Scottish conditions and we do not specify it on any external work.
Small cracks and fatigue splits in otherwise sound lead can be repaired with lead welding or self-adhesive lead repair systems. These are viable where the lead is structurally sound and the defect is isolated. Where lead is chronically cracked throughout, or where thermal cycling has caused wholesale lifting, replacement is the correct approach.
A standard chimney re-flashing (apron, step flashings and back gutter) in Auchterarder typically costs £350–£700 depending on stack size. Valley re-leading costs £300–£700 per run. We provide free, itemised quotes across PH3. Call 01738 245 298 to arrange a survey.
Like-for-like lead replacement does not require planning permission under permitted development. For properties in conservation areas or listed buildings, material changes may require Conservation Area Consent or Listed Building Consent. We identify constraints at the free survey stage.

The most reliable sign is a damp patch on the ceiling or wall adjacent to a chimney, valley, or flat roof upstand — particularly one that appears or worsens in wet weather. External signs include visible cracks in the lead surface, lifted flashing edges, missing wedge fixings, or white mineral staining (efflorescence) on masonry below a flashing joint.
