With more than 30 years of experience, we know how to install, replace, and seal roof flashings correctly, so you won’t have to worry when the next storm rolls in.

We work exclusively on single-story residential properties. We do not handle commercial or multi-story work.

We ensure that every job is completed safely, efficiently, and with a personal level of service that bigger operators can’t offer.

What Is Roof Flashing?

Roof flashing refers to thin pieces of metal installed around vulnerable points of your roof, like chimneys, skylights, vents, and valleys, to direct water away from those areas and into your gutter system.

Proper flashing prevents leaks, mould, and internal ceiling damage by sealing the joins where water most likely enters.

Common types of flashing we work with include:

  • Apron flashing (used at the base of walls or skylights)
  • Step flashing (used along roof-to-wall joints)
  • Valley flashing (used where two roof planes meet)
  • Chimney and vent flashing
  • Custom flashing profiles for unique roof designs

Without correctly installed or maintained flashing, even the best roof can leak.

Flashing Repair Perth

Rust, poor workmanship, or age can cause flashing to deteriorate or pull away from the roof, leading to leaks.

If you’ve noticed damp patches inside your home or water pooling around skylights or vents, damaged flashing could be the culprit.

Our flashing repair services include:

  • Resealing flashing joints with waterproof materials
  • Refixing loose or displaced flashing
  • Replacing rusted or corroded sections
  • Cleaning and reseating flashing around vents or skylights
  • Inspecting the surrounding roofing and gutters for related issues

We use durable, weather-resistant materials and proven techniques to ensure your flashing stays watertight and effective for years to come.
