Record the location and pattern of displaced tiles from a safe position. Have the visible tile, its relationship with neighbouring tiles and its support assessed. Displacement alone does not establish the complete repair boundary.
Which differences can be recorded from the ground?
Describe whether one tile sits differently or several rows form an irregular pattern. Identify its position relative to the ridge, gutter, dormer or wall. That orientation helps an investigator recognise the correct roof area. Do not try to assess concealed fixing from a distant viewpoint.
A broken tile, a displaced tile and a colour difference are different observations. Keep them separate in the report. Earlier and current photographs may help if the same location can be recognised. Do not use a ladder to confirm a suspected detail; preparation should remain limited to safely visible information and the question of which components require professional investigation.
Why do surrounding components belong in the same question?
A tile forms part of an interconnected roof plane. Ask how its position, overlap, support and neighbouring details will be assessed. A replacement should not merely resemble the existing colour; it needs to be considered suitable within the actual arrangement. A product name without assessment of those relationships is insufficient.
Other components may be involved where tiles meet a dormer, ridge or side wall. Record where assessment ends and which uncertainties remain. The eventual intervention may be small even when the investigation question is wider. This distinction prevents a simple visible change from being treated as fully understood before its relationship to surrounding construction has been examined.
Why does the existing tile profile matter?
Shape, dimensions and connections are relevant when retention or replacement is discussed. Similar colours do not make two tiles interchangeable. Ask how the existing profile is identified and which documentation or assessment supports the choice of supplementary material.
For historic roofs, retaining character and existing material may also be a separate consideration. The Cultural Heritage Agency’s information on historic tiled roofs emphasises retention. This does not mean every old tile remains usable. Actual condition and any protected status need separate assessment before a decision is made. Material recognition, technical suitability and heritage considerations should remain identifiable questions rather than being reduced to a visual colour match.
How should the chosen intervention be recorded?
Ask for a description of the assessed location and what was actually changed there. An overview photograph helps locate the work area later; detail information explains which connection or fixing was addressed. Also record where surrounding components intentionally remain outside the instruction.
Keep this information with earlier reports so a new displacement is not automatically treated as the same incident. Where several owners share a continuous roof, identifiable property and roof-area boundaries help. The planner can organise this preparation, but it prescribes no fixing method and cannot determine remotely how many tiles need replacement. That decision requires assessment of the actual components and their relationships.
Worth asking
Frequently asked questions
Is a matching colour enough for a replacement tile?
No. Shape, dimensions and connections also matter. Have suitability within the existing roof assessed.
Should I reposition a tile myself?
This guide advises neither roof access nor DIY repair. Have investigation and work safely planned by the relevant contractor.
Does one displaced tile imply complete replacement?
No. The work boundary follows from findings about the actual situation, not that single observation alone.
