Two roofing prices are only directly comparable when they cover the same work. A useful written quotation explains the problem, proposed materials, access and what happens if extra damage is uncovered. Rather than choosing by the headline figure alone, use a shared scope and ask each contractor to clarify the differences before agreeing.
1. Start with the findings and scope
Ask which roof sections and details need attention and why. Does the proposal cover an isolated repair, a new covering or work to the deck and supporting timber as well? Record what was inspected and any areas that could not be accessed. A contractor should distinguish an observed defect from an assumption that can only be checked once tiles or other materials are removed.
2. Identify the materials and junctions
For renewal work, check the proposed covering, underlay, battens and fixings where applicable. Ask what happens at chimneys, valleys, rooflights, ridges, verges and roof-to-wall junctions. Matching a visible tile colour is not the whole specification. The material needs to suit the roof and its exposure, with the surrounding weatherproofing details included or explicitly excluded.
3. Check access, protection and waste
Confirm whether scaffolding or other access equipment, waste removal and site clearance are included. Ask how the property will be protected while the roof is open and how weather may affect the schedule. Explain limited parking, shared access or nearby public areas in advance. The photograph here shows a real roof strip-off, illustrating why access and the condition underneath matter to the overall job.
4. Agree how discoveries and payment are handled
Ask for exclusions, payment stages and any deposit requirements in writing. Clarify how additional damage will be recorded, priced and agreed before extra work proceeds. Check whether the quoted total includes applicable tax. Do not assume that every quote is fixed regardless of discoveries, or that a verbal discussion changes the written scope without confirmation.
5. Clarify permissions and completion paperwork
Where approval is required, establish who will arrange it and which completion documents you should receive. Ask for any guarantee terms and insurance evidence directly rather than relying on a vague claim. Check what any stated protection actually covers and who provides it before agreeing to work. Keep the quotation, agreed changes, receipts and relevant certificates together.
6. Resolve differences before choosing
The Federation of Master Builders recommends itemised quotations based on the same scope, materials and assumptions. If one price omits flashing, insulation, access or disposal, ask for that difference to be explained. A clear answer about what is included is more useful than pressure to make an immediate decision. Choose the scope you understand and have agreed in writing.
We provide clear written quotations and explain when a repair may be sufficient instead of a full re-roof. When requesting a quote, include your postcode, the symptoms and any photographs taken safely. We will discuss the work and access needed; this guide is not a price promise or a substitute for inspecting the roof.
