A roof that stays dry in light rain can still have a defect. The timing of a leak gives useful clues, but it does not identify the cause on its own.
Record the pattern before the next visit
Note which room is affected, whether the rain was wind-driven and how long the leak took to appear. Photograph the stain and any visible water from a safe position. A simple history helps distinguish a recurring problem from a new event. Do not climb onto the roof or put yourself beneath a bulging or unstable ceiling to gather evidence.
What needs checking
The assessment may include the covering, roof junctions, valleys, chimney details and drainage. Water can travel before becoming visible indoors, so the point where it drips is not necessarily the point where it entered. A roofer should explain what the evidence supports rather than promising an exact diagnosis from one ceiling photograph.
Why covering the nearest gap can disappoint
An apparent gap may be part of the picture, but the surrounding arrangement also matters. If the tiles are unsuitable for the pitch, adding a surface patch does not correct that specification. If a valley or an adjoining roof is involved, the inspection needs to include those connections. The repair proposal should explain the route the water takes and the detail being corrected.
When a replacement discussion is worthwhile
If leaks keep returning or several roof areas are deteriorating, ask for the repair and replacement options to be explained. We focus on full replacements, with the preparation and junctions included in the plan. Keep receipts and photographs of previous work so the next assessment starts with the history rather than another guess.
