Lead flashing is a crucial component of any roof, designed to protect your home from water ingress by sealing joints and directing water away from vulnerable areas like chimneys, valleys, and roof edges. However, over time, even the most durable materials can wear down, and lead flashing is no exception. Knowing when your lead flashing needs repair or replacement is essential to maintaining the integrity of your roof and preventing costly damage to your property. At AJ Schutchings and Son, we specialise in roofing and leadwork, ensuring your roof remains watertight and in excellent condition. In this blog post, we take a look at the key signs that indicate your lead flashing may need attention.
One of the most visible signs that your lead flashing needs repair or replacement is the presence of cracks or splits. Over time, exposure to the elements can cause lead to expand and contract, leading to fatigue and eventual cracking. These splits can allow water to seep through, potentially leading to leaks inside your home. If you notice any cracks in your lead flashing, it’s essential to address the issue promptly to prevent further damage.
Although lead is known for its durability and resistance to corrosion, it is not entirely immune to the effects of time and environmental factors. Corrosion can occur, particularly in areas exposed to acidic rain, pollutants, or salt in coastal regions. Pitting, where small holes appear on the surface of the lead, is a common sign of corrosion. If left untreated, this can compromise the flashing’s effectiveness and lead to water penetration.
Lead flashing is typically secured in place using clips, nails, or by embedding it into mortar joints. Over time, these fixings can loosen, causing the flashing to lift or separate from the roof surface. This can create gaps where water can enter, leading to leaks and potential damage to the underlying roof structure. If you notice that your lead flashing is not sitting flush against the roof or is visibly lifting, it’s a sign that repairs are needed.
One of the most telling signs that your lead flashing may need replacement is the appearance of water stains on your interior ceilings or walls. These stains typically indicate that water is leaking through the roof, often due to compromised flashing. While the cause could be a range of roofing issues, deteriorating lead flashing is a common culprit, particularly around chimneys or roof valleys.
Mould and mildew growth inside your home can also signal a problem with your roof’s flashing. When water infiltrates your roof through damaged flashing, it can create the perfect environment for mould and mildew to thrive. If you notice musty odours, black spots, or other signs of mould in areas near the roof, it’s crucial to investigate the condition of your lead flashing.
While lead itself does not rust, rust stains or discoloration on or around the flashing can indicate that the materials used in conjunction with the lead (such as nails or fasteners) are corroding. This corrosion can weaken the flashing’s attachment points, leading to instability and potential water ingress. If you observe rust or unusual discoloration on your roof, it’s a good idea to have a professional inspect the flashing.
Lead flashing is built to last, often for decades, but it will eventually show signs of aging. If your home is older and the roof has never been replaced, the lead flashing may be nearing the end of its useful life. Signs of aging include a dull, oxidised appearance, brittleness, and general wear. While aging flashing may not show obvious signs of damage, it’s wise to have it inspected regularly to ensure it’s still performing effectively.
If your lead flashing has been repaired or patched in the past, it may be more prone to future issues. Temporary fixes can sometimes mask more significant problems, and patched areas are often weaker than the original material. If your flashing has been patched multiple times, it might be more cost-effective and secure in the long run to replace it entirely.
Lead flashing plays a vital role in protecting your home from water damage, but like all building materials, it can deteriorate over time. Being aware of the signs that your lead flashing needs repair or replacement can help you address issues before they lead to more extensive damage. At AJ Schutchings and Son, we have extensive experience in leadwork and roofing, offering expert inspections, repairs, and replacements to keep your roof in top condition.
