Lead Flashing Repair: Essential for Protecting Your Home from Water Damage

Lead flashing is a critical component of roof architecture, especially in the UK where the weather can be particularly harsh on buildings. It serves as a waterproof barrier at the points where the roof meets other structures, like chimneys or walls. Over time, lead flashing can deteriorate or become damaged, leading to potential water ingress and associated damage. This guide focuses on the importance of lead flashing repair and how to effectively address common issues.

Lead flashing is used because of its durability and malleability, making it ideal for sealing joints and preventing water penetration. However, it is susceptible to wear and tear due to constant exposure to the elements, temperature changes, and building movements.

Typical problems with lead flashing include cracking, corrosion, and detachment. These issues can be exacerbated by incorrect installation or the use of inferior materials. Signs of failing lead flashing include water stains on interior walls near the roof, damp patches, or visible damage to the flashing itself.

Effective Repair Techniques:

1. Inspection: Regular inspection is key. Look for signs of wear, lifting, or splitting in the flashing.
2. Cleaning: Before any repair, clean the area to remove dirt, debris, or moss, which can hinder effective repair.
3. Repointing: If the mortar joint has failed, it may need repointing. This involves removing the old mortar and applying a new, weather-resistant mix.
4. Replacing Damaged Flashing: In cases of severe damage, the affected section of flashing may need to be replaced. This should be done with care to ensure a watertight seal.
5. Sealing and Waterproofing: Apply a suitable sealant to any small cracks or gaps to restore the flashing's waterproofing ability.
