Separate a damaged tile from a wider roof problem
A crack, a missing piece and a tile that has slipped out of line are different observations. Each gives the inspector a different question to answer. Record the position and appearance in plain language rather than treating them as interchangeable faults. A photograph from the ground can show the general area even when it cannot show the complete defect.
A displaced tile also raises the question of why it moved. The assessment may need to consider how it sits with neighbouring tiles and the condition of its support and fixing arrangements. Simply moving it back into line does not explain whether the cause has been addressed. Ask for that distinction in the proposed work.
Inside the house, note any fresh stain or drip and when it began. A visible tile defect and an indoor stain may be connected, but their proximity alone does not prove the route. If there is no indoor symptom, describe that accurately too; a concern does not have to be leaking visibly before it is worth checking.
A replacement needs to fit, not just match the colour
A tiled roof is an assembly of overlapping units, not a single continuous sheet. A replacement needs to sit correctly with the units beside it and above it so those relationships are maintained. Tiles of a similar colour or overall size can have different profiles. That is why compatibility is a fitting question before it is an appearance question.
If you have spare tiles stored safely at ground level, mention them and provide a photograph of any markings without moving heavy stacks. Existing records from the roof installation or an earlier repair can also help. Do not remove a tile from the roof yourself to obtain a sample or read its underside.
An exact visual match may be difficult on a weathered roof. Discuss appearance separately from fit and performance so that you know what the finished repair is expected to look like. If a compatible product cannot be sourced, ask what alternatives are being considered and how much additional roof area they would affect.
Understand what the local repair includes
A useful repair description identifies the affected roof area and the work proposed there. It should make clear whether the price covers only individual tile replacement or connected work at a ridge, valley or flashing. That distinction is especially helpful when one quotation appears much larger than another for the same visible defect.
For example, a quote to replace two tiles and a quote that also repairs an adjoining junction are not pricing the same task. Ask for the evidence behind the extra work. There may be a sound reason for it, but a broad description such as “repair roof” makes it hard to see which problem each item addresses.
Monier’s maintenance guidance distinguishes broken tiles from ridge bedding and drainage concerns. That is a useful reminder to assess the components separately. A small visible defect does not establish that the whole roof is failing, and a small replacement does not establish that every neighbouring detail is in good condition.
Keep the repair proportionate and the record useful
Do not walk on the roof to count damaged tiles or test whether one is loose. An apparently small job can still require planned access and work at height. The cost of those arrangements is separate from the price of the tile itself, which helps explain why a two-tile job cannot be priced from material cost alone.
Before approving work, clarify how additional defects discovered during access will be communicated. A sensible record separates the agreed repair from anything awaiting a further decision. If the concern followed a storm, include the date and what changed; the timing is useful context but is not proof of the cause of every defect.
Keep the location, replacement information and completion photographs where available. If a leak prompted the repair, continue to note any new moisture after rain and share it with the person responsible for the assessment. That follow-up helps distinguish the repaired tile issue from a separate water-entry path that may need investigation.
