When other work may be needed
- A roof flashing repair does not fix every glazing or mechanism fault.
- Replacement flashing must suit the unit and roof configuration.
- Condensation can require a broader ventilation and moisture assessment.
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:
- Whether moisture appears around the frame, glass or ceiling below it.
- Whether it occurs without rain, as well as during rain.
- Skylight model, age or earlier installation records if available.
What to ask the quote to explain
Ask whether the quote concerns the surrounding roof and flashing, the skylight unit or a condensation investigation.

Common homeowner questions
Does a leaking skylight always need replacement?
No. The surrounding roofing or flashing may be involved. If the unit itself has deteriorated, replacement may be considered separately. The assessment should identify which part needs work and why.
How can I tell whether skylight moisture is condensation?
Note whether it forms on the inner glazing, occurs without rain or follows activities that add indoor moisture. Those observations help, but they do not replace an assessment. Rain entry and condensation can both need investigation.
What skylight details should I provide?
Send any accessible make, model or installation documents, photos from inside and a description of when moisture appears. Do not climb onto the roof to locate a product label.
