Roof leak detection & repairs · A focused guide
Why does my roof leak only when the wind blows one way?
Published by Big Ben Roofing Ltd
A leak associated with one wind direction needs that weather pattern included in the investigation. It does not identify a particular failed tile or flashing by itself. Record the affected room, the direction the weather appeared to come from and whether rain without wind produces the same symptom. Those observations help the assessor choose relevant roof and wall details to consider, while avoiding a diagnosis based solely on the stain's position or a dry-day surface view.
Compare events rather than one impression
Note a few dates when water appeared and, where already known, occasions when comparable rain caused no visible change. You do not need specialist weather instruments or a view from the roof. Describe the external elevation nearest the affected room and use ordinary terms if compass directions are uncertain. Keep observations separate from any assumption about how the water crossed the covering.
Ask how intermittent conditions will be addressed
The assessment may need information about a junction, an opening or an adjacent wall as well as the main roof. Ask what can be established in the current conditions and what further evidence would distinguish competing explanations. A proposal should connect the recommended work to findings, rather than promise that one material change will cure every leak that occurs in windy weather.
Useful details to record
- Record dates of wet and apparently dry events.
- Locate the affected room relative to an external elevation.
- Mention whether wind seems necessary for the symptom.
- Ask which uncertain causes remain after the assessment.
Use information already available from indoors or ground level. Do not climb onto the roof or disturb materials to complete this checklist.
Should I wait for another storm before contacting a roofer?
You can enquire using the observations already available. Explain that the problem is intermittent and supply the earlier dates. Do not expose yourself to severe weather merely to obtain evidence; further assessment arrangements should be discussed with the team.
Background reading
General guidance helps frame the questions. The cause, suitable materials and scope depend on inspection of the particular roof.

Can an intermittent roof leak be assessed on a dry day?
Prepare an intermittent leak history and understand what a dry visit can establish, what remains uncertain and when further investigation is needed.
What should be checked when a leak appears where the roof meets a wall?
Frame a roof-to-wall leak enquiry so the roof junction and adjoining wall condition are considered as a connected area.
Discuss what you have noticed
Include your postcode, the affected roof section and when the concern appears. The team will review the enquiry and confirm the next step, scope and availability.
