Roofing / Project guide

Roof leak investigation

Prepare a focused investigation of water entering through or near a roof. Connect the indoor observations to roof access, weather history and earlier repairs so a contractor can propose a useful assessment.

The decision this helps you make

What to aim for.

A documented explanation of the likely entry paths, remaining uncertainties and the next investigation or repair decision.

Start with the information below, then choose your property type for the access, operating and decision-making details that shape the project.

Define the scope.

  • Mark each affected indoor location and explain when water was first noticed.
  • Identify the roof areas, drainage features and adjacent walls the provider should consider.
  • Ask the investigator to separate immediate protection from permanent corrective work.

Put these records together.

  • Collect dated photographs taken during the event and after the area dried.
  • Gather roof plans, previous repair invoices and any active warranty documentation.
  • Record whether leakage followed rain, wind, snowmelt or operation of rooftop equipment.

Choose your property type.

Ask for a comparable proposal.

  • Describe inspection methods, accessible areas and what requires a separate investigation visit.
  • Ask how findings will be documented and whether proposed repairs are priced separately.
  • Identify responsibility for temporary protection, interior access and reinstating investigative openings.

Understand what affects the cost.

Ask providers to price the same scope and explain the assumptions behind these items.

  • The number of separate leak locations and the access needed to investigate them.
  • Concealed construction and the need to revisit during particular weather conditions.
  • Roof height, occupied-space protection and restrictions on bringing equipment to the work area.

Project: Roof leak investigation

Agree on the handover.

  • Request photographs connecting each finding to a marked roof or building plan.
  • Keep a record of temporary work and the circumstances requiring another visit.
  • Obtain a proposed repair scope that states assumptions and unresolved entry paths.

Questions before you begin.

Should the request ask for a roof replacement immediately?

Describe the observed leak and request an investigation that explains the available options. The contractor should identify the evidence supporting a local repair, further assessment or a larger replacement project.

What if the leak stops before the contractor arrives?

Keep the photographs, timing and weather observations. Ask what can be assessed during a dry visit and whether monitoring or another visit would help confirm the suspected source.

Continue planning.
