Tiverton’s Victorian terraces with high chimney density and original lead now 80–100 years old. Lead flashings are the most common single point of water ingress on Devon roofs, and the consequences of a failed flashing — damp penetration to the roof structure, ceiling and internal walls — are expensive to remedy. We carry out all lead work across Tiverton with correct code and dressed lead detail on Victorian and Edwardian stock. Call 01392 759 295.
Lead fails through thermal fatigue. It expands in summer heat and contracts in winter cold, and over time the metal cracks at folds, drips and stress points. In Tiverton’s climate, this cycling is significant — and on the most exposed properties, the service life of original lead is shorter than elsewhere. We carry out a full lead condition assessment on every Tiverton survey: step flashings, apron flashings, back gutters, valleys and parapet gutters are all inspected, not just the point of the presenting leak.
We specify lead by code for each application: code 4 for step and cover flashings, code 5 for valleys and parapet gutters where water stands. Under-specification of lead is one of the most common causes of premature flashing failure on Tiverton properties — and one of the most frequently seen errors when we take over from a previous contractor. We dress all lead correctly and solder joints where standing water is present.
The Victorian terraces in Tiverton’s town centre carry lead chimney flashings that range from original 19th-century installations to 1960s–80s replacement lead. The original Victorian lead — where it survives — is often in better condition than the replacement lead installed 40–50 years ago, because Victorian lead was cast rather than rolled and has a slightly different microstructure that resists thermal fatigue better. We assess lead age and condition individually and do not recommend replacement of sound Victorian lead simply because of its age.
Tiverton’s Exe Valley position creates wind and rainfall conditions that stress lead flashings more than equivalent installations in sheltered Exeter suburbs. South-westerly weather arriving up the valley hits exposed roof faces with sustained force, and lead step flashings on west-facing Tiverton chimneys experience higher stress cycling than equivalent flashings in sheltered locations. We factor this into fixing specification — lead clips rather than mortar tuck alone on exposed faces — and into inspection frequency recommendations for Tiverton properties.
Tiverton’s older properties occasionally carry parapet gutters and flat roof sections with original lead that is now well past its design life. Parapet gutter lead is the most failure-prone lead element on any property because it combines standing water risk with the full thermal cycling of an exposed horizontal surface. Code 5 is the minimum specification for parapet gutter lead — code 4 under-specifies the thickness for a standing water application. We assess parapet gutter lead as a priority on all Tiverton surveys where it is present.

📞 Call 01392 759 295“Lead flashing replacement on our chimney stack. Full replacement, not a patch job. No more damp in the bedroom.”
“Valley lead replaced on our Victorian property. Code 5 lead specified correctly. Clean job and no mess left.”
“Back gutter lead on our dormer replaced. They found secondary failure points during the survey. Good thorough approach.”
Step and cover flashing replacement from £350–£700. Valley lead from £500–£1,200 depending on length. Free survey. Call 01392 759 295.
Thermal fatigue — expansion and contraction cycles crack the metal at folds and stress points. Tiverton’s Victorian terraces with high chimney density accelerates this process on exposed properties.
Small cracks on otherwise sound lead can be sealed. If the lead is heavily fatigued with multiple failure points, full replacement gives a better long-term result. We advise honestly at the survey stage.
Code 4 for step and cover flashings. Code 5 for valleys, parapet gutters and any application where water stands. Under-specification is a common cause of premature failure.
Yes — on all joints where water could stand. Soldered joints are standard practice on valleys and back gutters.
A chimney lead replacement takes a full day. Valley replacement may take 1–2 days depending on length.
Yes — 10-year workmanship guarantee on all lead installations. Call 01392 759 295.
