Why Choose Us for Flashing Repair in Cottesloe?
Valleys and flashings get hammered by salt air in Cottesloe. If you've got an older home with original copper valleys, they corrode where the water sits. We see this constantly on beachfront properties around John Street and Eric Street, where salt exposure is heavy. Modern roofs with Colorbond get flash rust too, especially where materials meet. We replace valleys using copper or Zincalume, depending on your roof and original materials. For heritage homes, we match the original to keep character intact. Valley work typically runs $1,800 to $3,500 depending on length and complexity. It's not a job to cut corners on because a failing valley causes serious interior damage to a Cottesloe home.
Flashing problems in Cottesloe usually start at valleys where original copper is degrading from decades of salt air. We see cracked and failed flashings most often on properties within 800 metres of the beach. Heritage homes often have copper valleys needing specialist repair rather than replacement to preserve authenticity. On modern roofs, properly sealed flashings mean the difference between a dry roof and water damage to plaster ceilings.

Benefits of Flashing Repair for Cottesloe Properties
Seals the most common leak point
Flashing is the metal that seals the joins where the roof meets a chimney, wall, valley or vent. It's where most roofs leak, and where we fix more leaks than anywhere else.
Repaired properly, not bodged
If the flashing's just lifted or the seal's perished, we strip it back and reseal it. If it's rusted or was never installed right, we patch and re-secure the join so it sheds water again. Either way it's done to last, not bodged with a tube of silicone.
Stops the leak at the source
Sealing the flashing fixes where the water's actually getting in, so the ceiling stain stops spreading and doesn't come back next storm.
Fully insured
We carry $10M public liability and work safely across tile, metal and flat roofs throughout the Perth metro.
Our Flashing Repair Process in Cottesloe
- 1
Find the failed flashing
We inspect the chimneys, walls, valleys, vents and penetrations and identify which flashing has lifted, perished or rusted.
Why it matters: Flashing failures are easy to miss from the ground.
- 2
Strip the old seal
We remove the failed flashing or perished sealant back to a clean, sound surface.
Why it matters: New sealant won't bond over old, cracked material.
- 3
Reseal and re-secure
We reseal sound flashing and patch or re-secure it where it's lifted or rusted, lapped and fixed so water sheds away from the join.
Why it matters: Correctly lapped flashing sends water out, not in.
- 4
Check the surrounding roof
While we're at the join we check the nearby tiles, pointing and valleys, since flashing leaks often sit alongside other wear.
Why it matters: Where one thing's failed, the next is usually close.

My heritage home's original copper valley is leaking. Do I need to replace it? ▾
Not always. We often restore original copper valleys by sealing and treating corrosion. Replacement happens when damage is too advanced, and we'll source Zincalume or period-correct materials. Either way, expect 1,800 to 3,500 dollars for valley work.
How do I know if my flashing needs repair or just resealing? ▾
Look for water stains on interior ceilings, rust streaks on the exterior, or visible cracks in sealant. We use thermal imaging to find hidden leaks. A proper repair might be 600 to 1,200 dollars on heritage roofs, less on modern homes. Call within 24 hours if you're getting active leaks.
How much does roof flashing repair cost in Perth? ▾
A reseal of sound flashing is a small job. Patching and re-securing rusted or badly installed flashing costs more, especially around a chimney. We find what's failed first, then give you a price before any work starts. Call 08 6388 4492.
Can you fix chimney flashing? ▾
Yes. Chimney flashing is one of the most common leak points on a roof. We reseal or patch the flashing around the chimney so water sheds away from it instead of tracking down inside.
My roof leaks where it meets a wall. Is that flashing? ▾
Almost certainly. The join where a roof meets a wall is sealed with flashing, and it's a classic leak spot when that flashing lifts or perishes. We reseal or patch it to fix it for good.
Do you replace valley flashing? ▾
Yes. Rusted-through valleys are a major leak source on older Perth roofs. We repair the valley iron where it's still serviceable, and there's a dedicated valley replacement service if the whole valley's gone.
Will silicone fix my flashing leak? ▾
A smear of silicone might hold for a few months, but it's not a repair. Failed flashing needs the old seal stripped and the join resealed or patched properly. That's what actually lasts.
