1. Record what happens, not what you think caused it
Write down when the problem started and whether it appears during steady rain, wind-driven rain, cold mornings or after using the bathroom. Mark the room and ceiling area affected. A stain beneath a chimney is evidence of where water appeared, not proof that the chimney is the source.
For an intermittent leak, keep a simple dated log. Note wind direction if known, how long the rain lasted and whether the damp patch grew. Tell the roofer about previous repairs, including ones that worked temporarily.
- Date first noticed and frequency
- Photographs before decorating or cleaning the stain
- Previous invoices, guarantees and repair descriptions
- Any recent insulation, extraction or solar-panel work
2. Take useful photographs from a safe position
Take a wide view to show the roof and a closer view of the visible concern from ground level. Indoors, show both the affected area and enough of the room to locate it. Photograph loft conditions only where access and a proper walkway are already safe; ceiling plasterboard is not a walking surface.
Do not climb a ladder or walk on the roof to obtain a better photograph. Do not disturb suspect asbestos, electrical fittings or unstable ceilings. Keep people away from falling material or a bulging ceiling and seek urgent help where necessary.
- A whole-building view
- A close view of the stain with surrounding features
- An image showing changes during or after rain
- No unnecessary faces, documents or neighbouring interiors
3. Explain access restrictions before the appointment
Tell the office about locked side gates, conservatories, extensions, shared drives, parking restrictions and any vulnerable occupants. Mention a loft hatch in a cupboard or a roof hidden behind a higher building. The roofer can then explain what can be inspected at the first visit and whether specialist access is needed.
A drone view can show coverings and junctions but cannot prove that hidden insulation is dry or timber is sound. Ask what remains uninspected and whether opening-up or scaffold access is needed before a firm specification is possible.
4. Leave the visit with a clear next step
Ask for the likely cause, supporting photographs, limits of the inspection and whether repair and replacement are both viable. Separate confirmed defects from possible hidden work. If further investigation is chargeable, agree its scope and price before it takes place.
- What is confirmed, and what remains uncertain?
- What will the proposed repair actually address?
- Is any temporary work needed while a quotation is prepared?
- What access, further investigation or documents are still required?
