Check whether the quotes describe the same job
One proposal might replace a damaged tile while another includes work at an adjoining junction. A third may be an inspection price rather than a repair price. Put the descriptions beside one another and identify what each actually buys. A lower total is meaningful only after those differences are visible.
Start with the location and finding. “Repair leaking roof” does not tell you which component will be changed or why. Ask for the affected area, the observed defect and the proposed response in plain language. If the cause remains uncertain, distinguish the cost of investigating it from a price based on an established repair scope.
Previous work matters as context, too. If a leak has returned after patching, a new quotation should explain what it proposes to investigate or change this time. Otherwise, two similarly priced visits may repeat the same limited task without answering why the symptom persists.
Separate materials from access and preparation
The price of a replacement tile or a container of pointing is not the price of a completed repair. The job may also involve obtaining a suitable material, reaching the area safely, preparing the existing detail and handling waste. Ask which of these activities are included instead of assuming they are the same across quotations.
Roof height, pitch and restricted access can change the work arrangements. A defect close to a roof edge on one property may require a different approach on another. This is why a neighbour’s total, or an online price attached to a short description, may not be a useful benchmark for your own roof.
Preparation can explain another difference. A proposal that renews an unsound base is different from one that treats only a surface. Monier’s capping drawings distinguish bedding from pointing, while Selleys’ product guidance describes the contact required with adjoining tiles. Ask what the contractor proposes to retain, remove and prepare for the selected material.
Make exclusions and uncertain items visible
An exclusion is useful information when it tells you where the job stops. Check whether adjacent components, internal ceiling repairs, further investigation or inaccessible areas are outside the price. Do not assume an item is covered because it is near the repair or mentioned in an inspection photograph.
Ask how additional work will be proposed if access reveals a hidden defect. The useful answer describes how the new finding, scope and price will be communicated for a decision. An allowance or provisional item should be understandable enough that you can see what event might change the final amount.
Also clarify tax treatment, waste removal, inspection charges and any separate attendance fee in the actual quote. Do not fill gaps using a general website description. A written proposal for your property is the place to establish what is included and how payment relates to the agreed stages of work.
Compare the roof work and keep insurance records separate
Compare the components and areas, not just the total. One quotation may include inspection only, another a temporary measure, and another replacement flashing or tiles with access and removal included. Ask how uncertain or concealed defects will be handled. Internal drying, plasterboard and painting should be named separately if proposed rather than assumed to come with stopping the roof leak.
If you are also asking an insurer about the damage, retain dated safe photographs, inspection findings, earlier maintenance invoices and the itemised quotation. Ask the insurer what information and authorisation it requires before committing to non-urgent repairs. A roofing quotation describes proposed work; it is not confirmation that a policy covers the damage or that an insurer will pay it.
