Flashing is an essential component of any roof. It protects joints from weather damage, particularly water ingress. As such, it’s important to get it right, using flashing that’s suitable for the needs of the roof and the property. But what options are available? Read on as we look at the different types of flashing and materials that can be used.

Where is flashing used?

First and foremost, it’s important to look at some examples of how roof flashing is used:

  • Chimneys – Because chimneys protrude from the structure of the roof, they need flashing around the base to stop water pooling between their bricks and the tiles of the roof.
  • Skylights – Similar to chimneys, skylights are a structure which comes out of the roof and requires flashing to protect from water ingress around the edges
  • Any joints – As well as these specific examples, flashing is used to protect any joint in the roof. This could be a valley where two roofs meet, or just the edge of a roof where water runs off.

Different types of roof flashing structure

To protect these different areas of the roof, there are a variety of flashing structures that can be used:

  • Cap flashing – This sits flat against the roof around fittings like windows. Its ‘L’ shape causes water to run off away from fittings, so it doesn’t pool or make its way into the structure.
  • Continuous flashing – Flashing in one continuous piece is known as continuous flashing. It provides optimal protection for joints between a property’s vertical wall and the sloped roof edge.
  • Soaker flashing – These are installed on top of and also under roof tiles (dependent on tile/slate finish) where they meet a chimney for example.
  • Saddle flashing – Saddle flashing is used to saddle, cover and protect any protruding joists or beams which penetrate through a property’s exterior.
  • Step flashing – Like a step, this type of flashing covers both the horizontal surface of a roof with the vertical surface of a fixture.
  • Valley flashing – Flashing which is used in the valley of a roof, where two roofs join.
  • Vent pipe flashing – This cone-shaped structure is used to cover pipes which protrude from the roof.
