L Flashings

L flashings are precision-formed angle flashings that protect roof-to-wall joints, drip edges and chimney flashings. The L profile sits over the edge of the sheet and up the wall, directing water away from the seam. This listing covers the in-stock range in a broad selection of materials, from galvanised steel and aluminium to Galvalume, Colorbond and Zincalume, so there is a flashing to match the roof and the job.

Installation

Fix the L flashing over the sheet edge and up the wall with screws or nails, folding it to fit the surface where needed and sealing the top edge with a quality sealant. The angle channels water away from the seam, and the choice of material determines the finish and the corrosion resistance. For a paint-matched roof, use the Colorbond or Zincalume option so the flashing blends with the sheet.

Applications

• Roof-to-wall joints and chimney flashings
• Gable and verge ends, drip edges
• Step flashing combined with shingles
• Eaves, soffits and custom architectural trim

What You Need To Complete The Job

Seal the top edge of the L flashing with a flexible flashing tape such as WAKAFLEX, and close the sheet edge with compression flashing. Browse the Custom Flashing range for more profiles.

Frequently Asked Questions

What is an L flashing used for?

It protects the joint where the roof meets a wall, and it finishes drip edges and chimney flashings. The L shape sits over the sheet edge and up the wall to direct water away from the seam.

What materials are in stock?

The in-stock range covers galvanised steel, aluminium, Galvalume, Colorbond and Zincalume. Specialist materials like copper and stainless steel are available to order for heritage or high-end work.

Can I get a custom angle?

Yes. The standard is a 90 degree angle, with 45 degree and other angles available to order. Bespoke dimensions and lengths are fabricated on request, subject to minimum quantities.

How is it fixed?

Fasten it with screws or nails, fold it to fit the surface and seal the top edge with a quality sealant. The flashing works with the roof profile, so fix it firmly and keep the edge dressed down.
