When other work may be needed
- Clearing leaves will not repair a deteriorated valley.
- Access may involve carefully removing and reinstating surrounding roofing.
- A valley repair may reveal concealed defects that need an amended scope.
Before you request a quote
Provide your suburb, roof type if known, when the issue occurs, previous repairs and photographs taken safely. Ask for the findings and an explained written scope. Licence requirements depend on the work; verify the appropriate contractor with Service NSW.
Prepare a useful request for quotation
For this service, these details help define the assessment:
- The roof slopes near the affected indoor room.
- Any safely visible leaves, rust or overflowing water in the valley.
- Previous valley repairs and the roof material.
What to ask the quote to explain
Ask whether cleaning, valley replacement, lifting nearby tiles and reinstatement are included as separate parts of the scope.

Common homeowner questions
Why does the roof leak where two slopes meet?
The valley is a relevant place to inspect, but surrounding tiles, flashings and drainage also matter. Provide the location of the indoor stain and the rainfall pattern so the assessment can trace the leak back to the relevant roof area.
Is cleaning a valley enough to fix the leak?
It may resolve a problem caused only by debris, but it will not correct corrosion, damage or unsuitable surrounding details. The condition of the channel should be assessed after obstruction is addressed.
Does a valley replacement mean a complete new roof?
Not necessarily. A valley can be a defined repair area when surrounding components remain serviceable. The proposal should explain which tiles or sheets need temporary removal and what will be reinstated.
