About this service

Look closely where surfaces meet

Flashing helps manage water where a roof meets a chimney, wall or other feature. When a junction is worn or displaced, the issue should be viewed with the surrounding roof materials.

When a junction needs attention

  • 01

    Visible lifting, splits or wear at flashing

  • 02

    Water marks close to a wall or chimney

  • 03

    Previous patching around a roof penetration

Common questions

Can a leak near a chimney come from the flashing?

It can, but nearby masonry or roofing may also be involved. The source should be assessed first.

Where is flashing commonly used?

Flashing is used where a roof meets another surface, such as a wall, chimney or roof feature. The precise detail depends on that junction.

What photographs help explain a flashing concern?

A wider roof view and safe close views of the junction can help show its position and condition. Include any damp marks inside if relevant.

Can a junction be assessed without considering nearby tiles or slates?

Usually the neighbouring covering matters because it directs water towards and over the junction. The materials should be viewed together.
