How to Tell if your Leadwork Needs Replacing

When making sure your roof is in good condition, one of the things that often gets overlooked is the leadwork. People know to check for cracked and missing slates or tiles, as well as inspect the guttering and the roofline for signs of damage, but many don’t even think about the lead flashing. This can be a problem since your leadwork is just as important as any other part of your roof.

In this article, we’re going to take a look at 7 telltale signs that your leadwork needs to be replaced:

Visible damage

Lead flashing doesn’t last forever. Being exposed to the elements, as it is, will deteriorate over time thanks to adverse weather conditions, extreme changes in temperature, or just as a result of ageing. You should check your existing leadwork for any visible signs of damage, such as cracks, splits, or holes in the lead.

Visibly loose flashing

While inspecting the leadwork for damage, you should also check whether any sections have come loose. Typically, the result of poor installation or thermal expansion and contraction, loose, lifted, or dislodged lead flashing requires immediate attention from a professional roofer to prevent water from getting into your home.

Water stains and evidence of leaks

Speaking of water infiltration, this is a sure sign that something is wrong with your leadwork. While water seeping or dripping into your property during bad weather is hard to ignore, there are other, less dramatic indications. Brown or discoloured water stains on the walls or ceiling are often evidence of leadwork that is no longer providing a watertight seal.

Rust

Another sign that your lead flashing needs to be replaced is the existence of rust or other corrosion on the leadwork. This usually presents itself as reddish-brown patches on the flashing itself and, if left to its own devices, will only get worse, causing more deterioration to the metal.

Increased energy costs

Leadwork plays a key role in preventing thermal loss through your roof by creating a watertight seal where the roof joins with the walls, chimney stack, and other protrusions. If the lead flashing is compromised, it leads to air leaks and more rapid heat loss. This means you need to run your central heating for longer to achieve the same level of warmth. If your energy usage has increased recently and you can’t think of any other reason, it may be time to check your leadwork.

Mould

While not always attributable to damaged leadwork, the presence of mould in the home is certainly an indication of some kind of water ingress. The closer to the roof that the mould appears, the more likely it is to be a result of loose or broken lead flashing.

Daylight is showing through

If you can stand in your attic space with the light switched off and see daylight showing through the roof, either your roofing tiles or your lead flashing are no longer providing a tight seal. Whatever the cause might be, it’s important to get the problem fixed before it gets any worse.
