How to Check a Roof Replacement Quote Before You Sign
Last Updated: November 7, 2026
Quick Summary
A transparent roof replacement quote breaks the job into separate priced lines covering strip-out, waste disposal, timber work, insulation, the exact roof covering, leadwork, access, labour, VAT and guarantees. Ask for anything vague to be clarified in writing before you compare quotes or sign.
- Check that strip-out, waste disposal and access are each listed separately.
- Ask for the exact product name, grade and fixing method, not just "tiles" or "slates".
- Confirm whether the total includes VAT, and compare only VAT-inclusive totals.
- Read every exclusion and treat "allowance" or "provisional sum" lines as needing written explanation.
- Never pay a large deposit before the scope and exclusions are agreed in writing.

What Should Be Included in a Roof Replacement Quote
If you have been asked for a roof replacement quote, the first question is whether it spells out the work in full. Many homeowners compare two figures without realising the cheaper one leaves out key parts of the job. A fair quote should describe the work clearly enough to compare line by line, and show the evidence behind the scope rather than just a headline total.
A transparent quote separates the job into priced sections rather than one lump sum, each with a description, quantity or area, and specification.
- Strip-out and removal: the existing covering, battens, underlay and any felt, with the area stated in square metres.
- Waste disposal: how old materials leave site, whether a skip or grab lorry is used, and whether the waste transfer note is included.
- Structural and timber work: replacement of battens, sarking boards, fascia and rotten timbers, with a rate per metre and an allowance for unforeseen timber.
- Insulation: the product type and thickness, particularly where the roof is upgraded to meet thermal requirements.
- Roof covering: the exact product name, manufacturer, colour, grade and fixing method, not just "slates" or "tiles".
- Leadwork and flashings: chimney flashings, valleys, abutments and ridge details, each listed separately.
- Rainwater goods: guttering, downpipes and fascia work where affected, with the length stated.
- Access: scaffolding, towers or harness systems, shown as included or as a separate line.
- Labour: shown as its own line or built into each item, with the number of operatives and expected duration where possible.
- VAT: a clear statement of whether the total is VAT-inclusive, with the rate and amount shown separately.
- Guarantees: the workmanship period and any manufacturer product guarantee, with what each covers and what voids them.
A quote that is vague on materials, waste or access cannot be trusted yet. Ask for the missing detail in writing before comparing it with anything else.
Watch out: A quote that lists a single total with no breakdown of materials, labour, waste and access gives you nothing to compare and makes it almost impossible to spot what has been left out. For a complete checklist covering line items and red flags, see how to assess roof repair quotes.
The table below summarises the items a transparent roof replacement quote should price or describe separately.
| Quote item | What to check | Why it matters |
|---|---|---|
| Strip-out and removal | Area in square metres | Shows the scope of old material removed |
| Waste disposal | Skip or grab lorry, waste transfer note | Confirms old materials leave site properly |
| Structural and timber work | Rate per metre, allowance for timber | Reveals costs for hidden rot |
| Insulation | Product type and thickness | Matters where thermal upgrades apply |
| Roof covering | Exact product name, grade, fixing | Avoids vague terms like "tiles" |
| Leadwork and flashings | Each detail listed separately | Prevents missing weatherproofing work |
| Access | Scaffolding shown as included or extra | Access can be a major hidden cost |
| VAT | Stated separately, with rate | Stops misleading price comparisons |
Roof Replacement Quote Checklist: Reading Each Line
Read every line before you accept it. Use this checklist to test each item:
- Scope: Does it state the roof area, pitch and type of covering?
- Materials: Are the product names and grades written down, not just "slates"?
- Labour: Is labour shown as its own line, or buried in a single total?
- Waste: Is removal and disposal listed separately?
- Access: Is scaffolding included, excluded, or priced as an extra?
- Extras: Are repairs to timber, chimneys or lead listed as possible additions?
- Guarantee: Is the warranty period written into the quote?
If a line says "allowance" or "provisional sum", ask what that figure covers and when it will be confirmed, as these phrases can hide the true cost of the job.
How to Compare Roofing Quotes Fairly
Comparing quotes only works when you compare the same job. Ask each roofer to quote for the same scope, materials and start date, and give each the same written brief so differences reflect the work rather than what was asked for.
Build a comparison sheet with one column per quote and one row per item, marking each cell as included, excluded or unclear, and never accept a verbal answer as a substitute for a written one. The rows that matter most are the easiest to leave out: strip-out, waste disposal, scaffolding, timber repairs, leadwork, insulation, VAT and the workmanship guarantee.
Quote exclusions, assumptions and variation orders
Transparency depends as much on what a quote excludes as on what it includes. Read the exclusions line by line and ask the roofer to explain anything you do not understand, such as hidden timber repairs found after stripping, asbestos testing or removal, chimney stack repairs above roof level, and changes requested mid-job.
Payment schedules, deposits, warranties and cancellation terms
Ask for the payment schedule in writing and check how much is due before work starts, at each stage, and on completion. Be cautious about large upfront deposits, and ask what happens to any deposit if the start date slips.
How to verify a roofer and assess quote reliability
Price alone tells you little about reliability. Before comparing totals, check that the business name and address appear on the quote, ask for proof of public liability insurance and employer's liability insurance where staff are employed, and ask which competent person scheme or trade body the roofer belongs to. Request references from similar jobs and, where possible, ask to see recent work.
VAT and the final price
A common source of misleading comparisons is VAT. One quote may show a total excluding VAT while another shows a VAT-inclusive figure, making the first look cheaper when it is not. Ask every roofer to state whether the total includes VAT, to show the VAT amount separately, and to confirm the rate applied.
Watch out: A very low quote is not always a bargain. It may rely on cheaper materials, skip waste removal, leave out scaffolding or exclude timber repairs, and a very high quote may simply include more work. The only way to know is to read both documents in full and compare them line by line.
Roofing Quote Exclusions and Next Steps With CJU Roofing Specialists
Before you sign, look closely at the exclusions, such as hidden timber repairs found after stripping, asbestos testing or removal, and changes requested mid-job. Ask the roofer to explain in writing how any extra work will be agreed and priced. You can also browse examples of our completed roofing projects to see the standard of work we deliver.
Once you have a clear, complete quote, talk it through with the roofer. At CJU Roofing Specialists, we are happy to go through every line with you and explain any exclusions before you commit. You can request a quote or ask about our 5-year workmanship guarantee on full roof replacements through our contact page.
Watch out: Never pay a large deposit before the scope and exclusions are agreed in writing (Home maintenance and repairs).
Frequently Asked Questions
What should be included in a roof replacement quote?
A transparent roof replacement quote should set out the scope of work in plain terms: the area being covered, the removal and disposal of the existing roof covering, the underlay, battens, flashings and any leadwork, the chosen materials by name and specification, scaffolding or access arrangements, and the workmanship warranty. It should also state whether VAT is included, what the payment schedule looks like, and what happens if the surveyor finds unexpected timber or structural problems. If any of these are missing, ask for them in writing before comparing the price with other offers. Pricing varies with the size and complexity of the roof, so request a quote based on a survey of your property.
How do I compare roof replacement quotes fairly?
Compare quotes on what they include, not just the total. Put each quote side by side and check that they describe the same materials, the same amount of work and the same access arrangements. A lower figure may simply leave out scaffolding, waste removal or a warranty. Ask each provider to clarify any item that is unclear, and note how each one handles exclusions and variations. A quote that is much lower or higher than the others is worth questioning rather than accepting or dismissing straight away.
Should scaffolding be included in a roof replacement quote?
For most full replacements, scaffolding or another safe means of access is needed, so it should appear as a named line in the quote rather than being assumed. If it is excluded, the quote should say who arranges it and what it will cost you. Check whether the access method suits your property, particularly if it is a steep pitch, a listed building or a site with restricted access. Ask CJU Roofing Specialists to confirm how access is handled in any quote you receive from them.
