When it comes to maintaining your home, one of the most important aspects of your roofing system is the flashing. Lead flashing, in particular, is a crucial component used to prevent water from leaking into vulnerable areas such as joints, valleys, and around chimneys. Over time, however, lead flashing can become damaged due to various factors, and it is essential for homeowners to address these issues promptly to avoid significant damage.
In this blog post, we’ll explain everything you need to know about lead flashing repairs, including why it’s important, how to identify issues, and when to seek professional help.
What Is Lead Flashing?
Lead flashing is a material used to seal joints and intersections on a roof, helping to prevent water from seeping into the home. It is typically installed around roof features such as chimneys, skylights, and vents. Lead is favoured for flashing because it is durable, flexible, and resistant to corrosion, making it ideal for outdoor use in various weather conditions.
Despite its long-lasting nature, lead flashing is not immune to wear and tear. Environmental factors such as extreme weather, age, and improper installation can cause it to become damaged, leading to leaks and potential structural damage.
Why Is Lead Flashing Important?
Lead flashing plays a crucial role in protecting the integrity of your roof. Without properly functioning flashing, water can seep into vulnerable areas of your roof, leading to problems like:
- Water Damage: Moisture entering through damaged flashing can cause significant water damage to your roof, walls, and even the interior of your home.
- Mould and Damp: Persistent water leaks can lead to damp conditions, fostering the growth of mould, which can affect the air quality inside your home.
- Structural Damage: Over time, water infiltration can weaken the structure of your roof, leading to more costly repairs or even the need for a roof replacement.
Therefore, maintaining and repairing your lead flashing is vital to protect your home from these potential issues.
Signs Your Lead Flashing Needs Repair
As a homeowner, it’s important to regularly inspect your roof for signs of lead flashing damage. Some common indicators that your lead flashing may need repair include:
1. Visible Cracks or Holes
Cracks or holes in the flashing are a clear sign that it is no longer functioning as it should. This can occur due to weathering or physical damage, such as impacts from debris or falling branches. Even small cracks can allow water to penetrate and cause long-term damage.
2. Rust or Corrosion
While lead itself is highly resistant to corrosion, the nails or other metals used to secure the flashing may rust over time, compromising the integrity of the flashing. If you notice any rust or corrosion around the flashing, it’s important to have it inspected and repaired promptly.
3. Sagging or Displacement
Lead flashing is meant to sit securely in place around the roof. If the flashing becomes displaced or begins to sag, it may not be sealing the joints properly, leaving your roof vulnerable to leaks.
4. Water Stains or Dampness Inside the Home
Water stains on the ceiling or walls, particularly around areas where flashing is installed (such as chimneys or skylights), can indicate that water is getting past the flashing and into the home.
5. Deteriorating Mortar or Pointing
Lead flashing is often installed alongside mortar or pointing. If you notice that the mortar or pointing is cracked or deteriorating, it may indicate that the flashing needs to be checked and potentially replaced.
How Lead Flashing Repairs Are Done
Repairing lead flashing is a skilled job that requires professional knowledge and expertise. Here’s an overview of how the repair process typically works:
- Assessment: A professional roofer will begin by inspecting the damaged flashing to assess the extent of the damage and determine whether a simple repair or full replacement is necessary.
- Removing Damaged Flashing: The damaged or deteriorated flashing will be carefully removed, along with any rotted materials, such as old mortar or rusted nails, that may be contributing to the problem.
- Preparation and Cleaning: The area around the flashing will be cleaned to ensure a secure fit for the new flashing. Any old debris or loose materials will be removed to prevent future issues.
- Installing New Lead Flashing: New lead flashing will be installed and sealed in place, ensuring that it is fitted securely around the roof features. The new flashing will be carefully positioned to provide an effective barrier against water.
- Sealing and Testing: Once the new flashing is in place, it will be sealed, and the roofer will perform a water test to ensure that the flashing is doing its job of keeping water out.
When Should You Call a Professional for Lead Flashing Repairs?
While small flashing issues may seem like a DIY job, it’s best to call a professional for lead flashing repairs. Roof work is inherently dangerous, and even minor mistakes in the installation or repair of flashing can lead to leaks, which could result in serious damage. Professional roofers have the necessary experience, tools, and safety measures to handle these repairs properly and efficiently.
Additionally, professional roofers can assess the condition of your entire roof, looking for underlying issues that may not be immediately visible but could affect the performance of your flashing and roof as a whole.

Lead flashing is a critical component of your roof, protecting your home from water damage, mould, and structural issues. If you notice any signs of damage, it’s important to address the problem quickly to avoid costly repairs down the line.
