Keep the drainage path clear
Roof Valley Repairs in Mandurah
A roof valley collects water from two roof planes and directs it down the roof. A failed valley detail can move a lot of water toward the roof space.
Service focus
Repair failed or damaged tiled-roof valleys that are allowing water into the roof space.
Valley leaks can relate to damaged tiles beside the valley, deterioration in the valley material, poor tile alignment or a junction that no longer sheds water as intended. Because the valley carries concentrated runoff, a small defect can show up as a significant internal leak during rain.
Valley work is one of the business’s specialist services. The valley and the tiles along both edges need to be checked together. Replacing an unrelated tile away from the entry point will not fix a failed valley detail.
Tell Shane which part of the home is affected and whether the leak only appears in heavier rain. If the valley can be seen safely from the ground, a photo may help. Avoid standing under loose material and do not attempt to clear or inspect a steep roof yourself.

A practical start
Start with the details Shane can work from.
- 01
Map the internal symptom
The location of the stain helps relate the leak to a roof intersection or valley above.
- 02
Inspect the valley detail
The valley and tiles on both sides need to be considered together.
- 03
Repair the failed section
The scope is set by the condition of the valley, adjacent tiles and nearby junctions.
For safety, keep roof observations and photos at ground level. Do not walk on a wet, damaged or unfamiliar roof.
Roof Valley Repairs FAQ
Questions before you call.
Why do roof valleys leak?
Valleys carry concentrated rainwater. Damage, deterioration or poor alignment around the valley can create a path into the roof space.
Is a valley leak always obvious from outside?
No. The internal symptom, roof geometry and condition of adjacent tiles all help narrow down the source.
Can a valley be repaired without reroofing?
Often the scope can be localised, but it depends on the condition of the valley and the surrounding roof. The roof needs to be assessed before that call is made.
