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 tiled roofs leak, and on tile it's 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. Flashing sits outside our leak warranty, so we'll tell you honestly what we can and can't stand behind before we start.
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.
Flashing Repair in Cottesloe - FAQs

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 trace hidden leaks back to their source on the roof itself. A proper repair might be 600 to 1,200 dollars on heritage roofs, less on modern homes. Call us as soon as you can 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 so the join sheds water properly again.
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.
Do you repair flashing on a metal roof? ▾
For metal and Colorbond roofs we specialise in cleaning and repainting rather than leak work - our leak repair and leak warranty cover tiled roofs. If you've got a leak on a metal roof we'll tell you straight rather than take the job on.
Is flashing work covered by your warranty? ▾
No. Our 12-month workmanship guarantee covers repointing, rebedding, tile replacement and leak repairs on tiled roofs. Flashing, flues, whirlybirds and other roof penetrations sit outside it, and so do metal roofs. We'll set out exactly what's covered before you commit.
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.
What Our Customers Say
"Can highly recommend this business. Great communication, tidy work, and excellent result."
"I wanted to give 6 stars. Highly recommend Ryan and the team for roof restoration. From the beginning, communication was clear and they delivered exactly what they said they would — something that really stood out after being ghosted by other companies. The pricing was very honest compared to the many quotes we received for the same work, and the quality delivered was excellent. Ryan also gave us valuable time and guidance when choosing colours, which we really appreciated. Not once did I have to wait for a response, the site was left clean, and the entire process felt smooth and professional from start to finish. Ryan is an absolute gem ~ reliable, knowledgeable, and genuinely great to deal with. Honestly, I cannot fault anything. Very grateful we trusted Ryan and his team with restoring our late-70s roof. Thank you!!"
