UNDERSTAND THE PROBLEM

What this service addresses

A ceiling stain shows where water has appeared indoors. The leak may start somewhere else. Water can travel along roof components before it becomes visible indoors. A roof leak assessment connects the weather pattern, the affected room and the condition of the roof covering, flashings and drainage. The aim is a repair that addresses the cause rather than another patch over the stain.

What you might notice

  • A ceiling stain appears or grows after rain
  • Drips return during wind-driven rain
  • Dampness develops near a chimney, skylight or wall junction
  • A previous sealant repair has started leaking again

What we check

  • Review when the leak occurs and where moisture is visible
  • Inspect accessible roof coverings, junctions and drainage paths
  • Identify the likely water entry route and explain the evidence
  • Define a repair and any further investigation needed

When other work may be needed

  • An inspection may need safe access, suitable weather or a return visit to confirm an intermittent leak.
  • Ceiling damage, plumbing leaks, condensation and structural defects may need separate assessment.
  • An online description or photo cannot establish the complete cause.

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 affected room and where water first appears.
  • Whether it happens in light rain, heavy rain or wind-driven rain.
  • Previous patches, solar work or other recent changes.

What to ask the quote to explain

Ask how the proposed repair relates to the observed entry route, what could not be inspected and how the result will be checked.

Common homeowner questions

Why does my roof leak only in heavy rain or strong wind?

Heavy rain may reveal an obstructed outlet or drainage problem, while wind-driven rain can enter a vulnerable flashing, tile overlap or penetration. Describe the rain intensity, wind direction and how long it takes for the stain to appear. Water can travel before it becomes visible indoors, so do not assume the nearest tile is the cause. An inspection needs to follow the water path and check the surrounding roof before choosing a repair.

Can one leaking section be repaired without replacing the whole roof?

A local repair may be appropriate when the surrounding roof is serviceable and the defect can be corrected. Widespread deterioration or several failing components can make a broader scope more sensible. An assessment should explain the condition and the reason for either option.

What information should I send about a roof leak?

Provide the suburb, roof material if known, the affected room, when the problem started and whether it happens every time it rains. Photos taken safely from indoors or ground level and records of earlier repairs can help. Do not climb onto the roof to collect evidence.

Should a ceiling stain be painted over after a storm?

First check the water source and whether the affected materials have dried and remain sound. Painting over a stain can hide a recurring leak. Tell us if the mark spreads, drips return or the ceiling shape changes.
