Valley Iron Replacement Services
Roof valleys are the channels formed where two roof planes meet, and they carry some of the heaviest water flow on your entire roof. The valley iron (typically galvanised steel or lead) deteriorates over time due to constant water exposure, debris accumulation and galvanic corrosion. A corroded or perforated valley is a guaranteed source of leaks that cause serious damage to internal walls, ceilings and framing. We remove the old valley iron, inspect the underlying structure, and install new custom-formed Colorbond or zinc valley flashing that is designed to handle high-volume water flow for decades.
What's Included
Benefits
Stop Valley Leaks
A new valley iron eliminates the rust holes, perforations and failed joints that allow water to bypass your roof into the structure below.
Prevent Internal Damage
Valley leaks often go undetected until significant damage has occurred to ceilings, walls and timber framing. Replacing valleys proactively avoids costly repairs.
Long-Lasting Materials
Colorbond and zinc valley flashing are highly corrosion-resistant and designed to outlast the surrounding roofing material.
Our Process
Valley Inspection
We inspect each valley to assess the condition of the existing flashing, identify corrosion and check the underlying structure.
Tile Removal Along Valley
Tiles on both sides of the valley are carefully lifted and stacked to expose the full length of the valley iron.
Remove Old Valley Iron
The corroded valley flashing is removed and the valley board is inspected for rot or damage. Repairs are made as needed.
Install New Valley Flashing
Custom-formed Colorbond or zinc valley flashing is installed with correct overlaps and sealed joints for watertight performance.
Replace Tiles & Clean Up
Tiles are carefully replaced and re-bedded at the valley edge. Valley mesh is fitted if requested, and the area is cleaned.
Frequently Asked Questions
How do I know if my valley irons need replacing?
Signs include water stains on internal ceilings near valley locations, visible rust or holes when viewed from the roof, and debris accumulation in the valley channel. An inspection from the roof cavity can also reveal deterioration.
Can valley irons be patched instead of replaced?
Temporary patches can slow a leak, but once a valley iron has corroded to the point of failure, replacement is the only reliable long-term solution.
What material is best for valley flashing?
Colorbond steel is the most popular choice for its corrosion resistance and colour range. Zinc is also an excellent option and is often used on heritage properties. We recommend the best material based on your roof type.
