Lead Valley Repairs Cork — Guaranteed Roof Valley Relining & Waterproofing
Lead Valley Repair & Relining Services in Cork
A roof valley is the V-shaped junction where two sloping roof sections meet. Because it channels hundreds of gallons of rainwater directly off your roof into the gutters during severe storms, your lead valley is under constant hydraulic stress. Over time, thermal expansion causes lead sheets to split, timber valley boards underneath to rot, and surrounding tiles to shift.
Our fully certified tradesmen bring 17+ years of specialist leadwork experience to restore compromised roof valleys back to a 100% watertight condition.
1. Code 4 & Code 5 Sheet Lead Replacement: We strip out split, thin, or fatigued lead and install heavy-duty Code 4 or Code 5 milled sheet lead, dressed precisely to pitch angles in maximum 1.5-metre lengths to allow for natural thermal movement without cracking.
2. Emergency Lead Valley Leak Repair: Tracing hidden leaks along valley channels, applying temporary high-grade waterproofing membranes during downpours, and sealing split joints until permanent relining takes place.
3. Timber Valley Boarding & Underlay Restoration: Water leaking through split lead quickly rots underlying timber valley boards. We cut out decayed plywood/OSB decking, reinforce rafter supports, and lay breathable waterproof underlayment before fitting fresh lead.
4. Tile Edge Realignment & Mortar Bedding: Trimming back slate or concrete tile overhangs to maintain a clean 100mm to 150mm open water channel, re-bedding tile edges securely in weather-resistant polymer mortar.

Frequently Asked Questions
Leaks originating from a roof valley typically create damp patches or brown ceiling stains directly beneath where two roof slopes intersect inside your attic or upper-floor ceilings. During heavy rain, you may also notice water bypassing the valley and running straight down interior party walls.
If the lead has a minor split in a single location and the underlying timber decking is dry and solid, we can execute a localized lead weld or high-grade bitumen patch. However, if the lead is old, thin, and brittle with multiple fatigue cracks, complete relining with fresh Code 4/5 lead is the only reliable long-term solution.
Lead expands when heated by the sun and contracts when cooled by rain and frost. If original lead sheets were installed in excessively long single strips (over 1.5 metres) or nailed too tightly without room for movement, continuous thermal expansion causes the metal to fatigue and split down the center line.
Repair costs depend on valley length, roof pitch, accessibility, and whether timber boards underneath need replacing. Small localized repairs are very affordable, while full valley relining with fresh Code 4 lead is calculated per linear metre. We provide 100% free site visits and itemized written quotes upfront.
