Quick answer
A useful quotation should identify the work proposed, key materials, access or scaffolding, waste arrangements, payment terms, anticipated programme and applicable guarantees. Where diagnosis is not obvious, it should also be clear what defect the proposed work is intended to correct.
At a glance
- A quotation without a stated defect is difficult to compare against another.
- Access and scaffolding costs are a common source of later disagreement.
- Waste removal should be stated, not assumed.
- Guarantee terms should be attached, not just mentioned verbally.
The scope should follow the diagnosis
A quotation is more useful when it links the proposed work to a stated finding — for example, which slates are being replaced and why, or which section of flashing has failed and what will replace it. Where the defect is not obvious from the description, the quotation should say plainly what problem the work addresses. This makes it possible to compare quotations properly rather than comparing headline totals for different scopes.
It should also be clear whether the price is fixed for the described scope, or provisional pending further findings once work begins. Both approaches are legitimate, but they should not be confused with each other. A provisional price should explain how any additional work would be identified, agreed and charged, so there is no ambiguity if the roof turns out to need more than first thought.
The practical detail that avoids disputes
Beyond the scope of work itself, a written quotation should set out the commercial and practical terms clearly enough that neither side needs to guess later. Vague wording such as 'materials as required' or 'scaffolding if needed' tends to store up disagreement for later in the job, when it is harder to resolve calmly.
- Key materials to be used and their specification.
- Access or scaffolding arrangements and whether these are included.
- How waste and debris will be removed.
- Payment terms and any staged payment schedule.
- An anticipated programme, including realistic weather allowance.
- Guarantees that apply, and what they cover.
- Contact details for queries once work has started.
Documents worth asking for alongside the quotation
It is reasonable to ask for the quotation to be accompanied by, or to reference, a copy of the inspection notes or photographs that informed it, a materials specification sheet where relevant, and written confirmation of insurance. None of this needs to be elaborate, but having it in writing means there is something concrete to refer back to if a question arises once work is under way, rather than relying on memory of a verbal conversation.
Reading a quotation critically before signing
Before accepting a quotation, read it as though you were the one who would have to enforce it if something went wrong. Does it say clearly what will be done, by whom, using what materials, over what timescale, and for what total cost? If any of these are missing or expressed only in general terms, it is worth asking for a revised version rather than relying on a verbal assurance that the detail 'is understood'. A short delay while a quotation is clarified is a small cost compared with a dispute part-way through the work. It is also worth checking that the quotation is dated and clearly attributed to the business you have been dealing with, rather than an unnamed template that could apply to any job.
What we would check
During an inspection, areas we would normally look at for this include:
- Whether the stated defect matches what can be seen or evidenced.
- Whether materials specified suit the existing roof construction.
- Access, scaffolding and waste arrangements are stated, not assumed.
- Payment terms and programme are realistic and clearly written.
- Guarantee documentation is attached rather than referred to only verbally.
