New Lead Flashing to Dormer Window – Professional Roof Repairs

T and T Roofing recently carried out new lead work flashing to a dormer window, ensuring the property was fully protected against leaks and water ingress.
Dormer windows are a common weak point on a roof, and if the flashing around them begins to fail, rainwater can quickly penetrate into the property, causing damp and structural damage.

What Is Lead Flashing?

Lead flashing is a highly durable, weather-resistant material that is fitted around vulnerable areas of a roof such as dormer windows, chimneys, and valleys.
Its purpose is to create a watertight seal, directing rainwater safely away and preventing leaks.

Our Dormer Window Lead Work

For this project, our team carefully removed the old, worn flashing and replaced it with brand-new, high-quality lead.
The flashing was cut and dressed to fit perfectly around the dormer window, providing a neat finish and long-lasting protection.
Once installed, the surrounding tiles were re-bedded to ensure a seamless and weatherproof result.

Why Replace Dormer Window Flashing?

If lead flashing becomes cracked, loose, or corroded, water will inevitably find its way inside.
Common signs that your dormer flashing may need replacement include:

• Damp patches or stains on ceilings and walls near the dormer
• Visible gaps, cracks, or deterioration in the flashing
• Loose or missing tiles around the dormer window
• Persistent roof leaks during heavy rain
