At A1 Roofing Coventry, we understand the importance of proper flashing installation to prevent water damage and ensure a long-lasting roof. In this article, we will guide you through the process of installing lead flashing on a pitched roof in Warwickshire.

Flashing is a critical component of a pitched roof, designed to direct water away from the roof's vulnerable areas, such as chimneys, walls, and valleys. Lead flashing is a popular choice due to its durability and water-resistant properties.

Before installing lead flashing, ensure the roof is clean and free of debris. Inspect the roof for any damaged or loose tiles, and repair or replace them as needed.

Measure the area where the flashing will be installed, taking into account the width of the chimney or wall. Cut the lead to the required size, leaving a 50mm overlap at the edges.

Apply a thin layer of lead flashing compound to the back of the lead, ensuring it covers the entire surface. This compound helps to create a watertight seal between the lead and the roof.

Place the lead flashing over the chimney or wall, ensuring it is centered and the edges are aligned with the roof's edges. Use a hammer and a lead flashing tool to shape the lead around the chimney or wall, creating a tight seal.

Use lead clips or nails to secure the lead flashing to the roof, spacing them at 150mm intervals. Make sure the clips or nails are not over-tightened, as this can cause the lead to become loose over time.

Apply a bead of lead flashing compound to the edges of the lead, ensuring a watertight seal. Use a lead flashing tool to smooth out the compound and create a neat finish.
