Why Choose Us for Valley Replacement in Dianella?
Valleys are where water runs fastest, and original galvanised valleys in Dianella homes from the 1960s-1970s have corroded through after 50 years. When valleys fail, water runs straight into the roof cavity instead of away from the home. Leaves also pack tight in valleys and trap moisture, accelerating corrosion from underneath. We replace corroded valleys with new Colorbond, ensuring water flows fast and clean toward the gutters. Replacement is straightforward once we're up there and is often done as part of a full restoration. Standing water in a valley is a sign replacement is needed. Fixing valleys stops a serious cause of ceiling leaks in older Dianella homes.
Valleys are where two roof sections meet and water flows down. Dianella's original galvanised valleys from the 1960s-1970s corrode and leak. We replace them with modern materials that last longer and seal properly to prevent water entry.

Benefits of Valley Replacement for Dianella Properties
Stops a major leak source
The valleys carry the most water on your roof. When the valley iron rusts through, it leaks heavily in a downpour. Replacing it stops one of the worst leaks a roof can have.
New valley iron, properly lapped
We replace the rusted valley with new iron, lapped and sealed so water runs straight off, not back under the tiles.
Tiles lifted and reset cleanly
We lift and reset the tiles either side of the valley cleanly, and repoint where needed, so the finished job is watertight and looks right.
Done before it does damage
A leaking valley wrecks ceilings, insulation and timber. Replacing it early costs far less than the water damage it causes if left.
Our Valley Replacement Process in Dianella
- 1
Inspect the valleys
We check the valley iron for rust, holes and lifting, and look at the tiles either side.
Why it matters: Valleys often rust from underneath where you can't see it.
- 2
Lift the edges
We carefully lift the tiles along both sides of the valley to get the old iron out.
Why it matters: Clean removal protects the surrounding roof.
- 3
Fit new valley iron
New valley iron goes in, lapped and sealed to shed water away from the roof structure.
Why it matters: Correct lapping is what keeps water out.
- 4
Reset and check
We reset the tiles, repoint where needed, and check the valley sheds cleanly.
Why it matters: The job's only done when the roofline's back to right and watertight.

What happens when a valley starts leaking? ▾
Water runs into the roof cavity instead of off the edges. In Dianella, this causes ceiling stains and timber rot inside the roof space. Replacement stops the leak immediately.
How much does valley replacement cost? ▾
Depends on roof size and how many valleys need work. In Dianella, we usually identify corroded valleys during a restoration and include replacement in the overall quote.
How much does roof valley replacement cost in Perth? ▾
It depends on how many valleys need doing, their length, the roof type and access. Call 08 6388 4492 or request a quote for a fixed price. It's a targeted repair, usually far cheaper than the water damage a failed valley causes.
How do I know my valley needs replacing? ▾
Rust stains, flaking metal, or a leak that shows up in heavy rain near where two roof sections meet are the usual signs. Often you can see the valley iron has rusted thin or holed. We confirm it on inspection.
Can you replace a valley on a tiled roof? ▾
Yes. We lift and reset the tiles either side cleanly, fit the new valley iron, and repoint where needed so the finished job is watertight and looks right.
Will replacing the valley stop my leak? ▾
If the valley is the source, yes. Rusted valleys are one of the most common heavy-leak points on older Perth roofs. We confirm the valley is the cause before replacing it.
Can you just repair it instead of replacing? ▾
Sometimes, if the iron is mostly sound. But once valley iron has rusted through, patching it rarely lasts. We'll tell you honestly whether a repair or a full replacement is the right call.
