Leadwork is one of the most important yet often overlooked elements of a roofing system. Installed around chimneys, valleys, dormers and roof junctions, it forms a watertight seal that protects vulnerable areas from water ingress. When lead flashing begins to fail, it can quickly result in leaks and internal damage.
For homeowners in Paddock Wood, Kent, recognising the early warning signs of failing leadwork can prevent more extensive roofing issues. At Paddock Wood Roofing, we regularly inspect and repair leadwork to ensure properties remain protected against the elements.
Visible Cracking or Splitting
One of the earliest signs of failing leadwork is visible cracking along the surface. Over time, lead expands and contracts with temperature changes. If the material has been incorrectly installed or has aged significantly, stress fractures may appear.
Small splits can allow rainwater to penetrate beneath the flashing, particularly around chimneys and roof valleys. Early detection and repair can prevent moisture from reaching the roof timbers and interior spaces.
Lifting or Loose Flashing
Lead flashing should sit securely against masonry and roof coverings. If sections begin to lift, curl or detach from the structure, water can easily enter behind the flashing.
Loose lead may result from worn fixings, deteriorating mortar joints or movement within the roof structure. Even slight separation can compromise the waterproof seal, making prompt attention essential.
Damp Patches Near Chimneys or Roof Junctions
Failing leadwork often first becomes noticeable inside the property. Damp staining on ceilings or walls near chimneys, skylights or roof valleys may indicate water ingress around flashing areas.
Because these sections are natural weak points in a roof, damaged lead is a common cause of persistent localised leaks in homes across Paddock Wood.
Corrosion and Surface Deterioration
Although lead is highly durable, it can deteriorate over time, particularly if exposed to pollutants or poor drainage conditions. Surface pitting or uneven weathering may suggest that the material is weakening.
Regular inspections help identify whether the lead remains structurally sound or requires replacement to maintain effective waterproofing.
Gaps in Mortar or Sealant
Lead flashing is often secured into brickwork using mortar or specialist sealants. If these joints begin to crack or crumble, the flashing may lose its secure fixing.
Gaps along mortar lines allow water to seep behind the lead, which can then track down into the roof space. Addressing these minor defects early helps avoid more extensive repairs.
Why Early Action Matters
Leadwork protects the most vulnerable areas of your roof. When it begins to fail, water can enter areas that are difficult to access and slow to dry, increasing the risk of timber decay and structural damage.
Responding to early warning signs reduces the likelihood of internal damp issues and helps preserve the integrity of the surrounding roof covering.
The Importance of Professional Repair
Lead installation and repair require precision and experience. Incorrect fitting or inappropriate sealing methods can shorten the lifespan of the flashing.
At Paddock Wood Roofing, we assess the condition of existing leadwork carefully before recommending repair or replacement. Our approach ensures that flashing is correctly installed and securely integrated with both masonry and roof coverings, providing reliable protection for properties in Paddock Wood, Kent.
