Two parts of the same detail
Ridge caps cover the meeting line at the top of a tiled roof, while hip caps follow the sloping external corners. On a bedded system, mortar forms the bed beneath those caps. The exposed pointing is a separate part of the detail. The terms describe different work, even though a quotation may discuss them together.
Monier’s ridge and hip capping drawings label mortar bedding and flexible pointing separately. They help explain the arrangement of the components, rather than prescribe a repair for an existing roof. Selleys’ Point Works guidance also requires contact with the roof and ridge tiles. The visible finish therefore needs to be considered as part of a connected detail.
When discussing a repair, ask which material is cracked and what evidence supports that conclusion. “Ridge repair” is a useful category but an incomplete work description. You should be able to understand whether caps are being lifted and rebedded, whether existing bedding is being retained, and where new pointing will be applied.
What a crack can and cannot establish
A fine surface crack, a visible gap and a displaced cap are different signs. Record their location from a safe ground-level position, including whether one short area or several roof lines appear affected. Do not touch or push caps to test their stability. That assessment belongs with the person planning safe access to the roof.
Repointing may be considered where the supporting bed remains suitable and the problem is in the exposed finish. If the bedding or cap arrangement needs renewal, covering it with a new finish does not remove that underlying issue. Ask how the assessment distinguishes those conditions rather than accepting either treatment as a default package.
A crack also does not establish the source of an indoor leak. If ceiling moisture prompted the enquiry, describe its timing separately. The inspection may need to follow other details nearby as well. Keeping the visible ridge concern and the indoor symptom distinct allows the explanation to show whether and how they are connected.
Why the length and preparation change the scope
A proposal for a short ridge section differs from a proposal for every ridge and hip. Ask for the roof lines to be identified in a photograph, sketch or written description. An approximate length is useful only when everyone understands which lines it includes and whether any areas are excluded or awaiting closer assessment.
Preparation is another meaningful difference between quotes. The scope should explain how unsound material will be dealt with and which base is being retained. Avoid comparing only the name of the pointing product or the final colour; neither tells you what happens beneath the visible finish or how much work is included.
The selected product also has application and curing conditions. Weather can affect when that work can be carried out, and the requirements vary by material. Discuss scheduling with the contractor instead of treating a dry-looking roof on the morning of the appointment as proof that all conditions are suitable.
Make the repair decision understandable
Before approving the work, ask for three things in ordinary language: what was found, which ridge areas need attention and what treatment is proposed for each. If some areas need rebedding and others only repointing, the description should preserve that distinction. A single broad label can otherwise hide a useful difference in scope.
Ask how broken adjacent tiles or other defects found during access will be handled. They may be connected to the work area, but they are not automatically included because the quote mentions ridges. Clarifying the approval process for additional work helps keep a targeted repair from becoming an undefined programme of roof maintenance.
Completion photographs and a written record can show the locations worked on and any follow-up recommended. Keep them with the original observations. The purpose is to understand what has changed and what remains, rather than to judge concealed bedding solely from the appearance of the new pointing.
