Three roofing quotes, three different prices. Which one is fair? The roof replacement cost UK homeowners see online is only half the answer, because two quotes with the same headline can describe very different jobs. This guide shows what a fair roof replacement quote includes, why prices differ, and how to compare roofing quotes and check a roofer before you hire.
How Much Is Roof Replacement in the UK?
The cost of roof replacement UK buyers face depends on roof size, covering, access and extras. For a fuller breakdown by roof and house type, see our new roof cost UK guide. These are other companies’ figures, not ScopeCheck prices, and they do not all say whether VAT is included.
Why Roof Replacement Quotes Vary So Much
A fair price for roof replacement is hard to judge because quotes are rarely like for like. The main reasons are:
- Scope: one roofer includes scaffolding and skip hire, another does not.
- Covering: different tiles, slates or flat roof systems, sometimes described only as “tiles”.
- Hidden repairs: an allowance for rotten timber in one quote, nothing in another.
- Extras: leadwork, chimney work, fascias and guttering may be in or out.
- VAT: some quotes include it, others add it later.
That is why roofing quotes UK homeowners collect can look 30% or 40% apart and still be fine. The gap often reflects what is missing, not what is cheaper. Our guide on why “included in the price” causes problems explains how vague wording creates disputes.
What Should a Roof Replacement Quote Include?
If you ask what should a roof replacement quote include, start with this checklist. For more detail, read what a roofing quote should include.
- Scaffolding, including hire period, erection and dismantling
- Stripping the old covering
- Battens and breathable membrane
- The new covering, named by product
- Ridge and hip tiles
- Leadwork, flashings and chimney work
- Fascia, soffit and guttering, if included
- Waste removal and skip hire
- An allowance for timber repairs and how extra work is priced
- Guarantee terms and who backs them
- VAT, deposit and stage payments
- Start date and expected duration
Is scaffolding included in roof replacement cost? Not always. Checkatrade lists scaffolding and skip hire as extra costs to budget for. Never assume it is covered.
What Is Often Missing from a Cheap Roofing Quote?
A roof quote too cheap to be true is worth checking, not dismissing. Look for missing items before you ask whether it is a scam. The figures below are hypothetical and not UK market prices.
| Item | Quote A (£9,600) | Quote B (£7,400) |
|---|---|---|
| Scaffolding | Included | Not mentioned |
| Waste removal | Included | Excluded |
| Leadwork | Included | Excluded |
| VAT | Included | Not stated |
| Guarantee | Described | Not described |
Quote B is £2,200 cheaper on paper, but the real gap cannot be known until the missing items are priced. Ask Roofer B to confirm each in writing, then compare. Read builder quote much cheaper than the others? for a step-by-step check.
How to Compare Roofing Quotes Like for Like
To compare roofing quotes, follow these steps:
- Ask every roofer to price the same specification.
- Request an itemised breakdown, not a single total.
- Put VAT on the same basis for every quote.
- List every exclusion and ask what each would cost.
- Check allowances. A PC sum or provisional sum is an estimate, not a fixed price (see what a PC sum is and provisional sums).
- Compare timelines and guarantees.
- Compare payment terms and deposits.
- Get the revised answers in writing, then compare totals.
Fixed price vs estimate roofing: a fixed quote should stay the same unless the scope changes, while an estimate can move. Our guide on quote or estimate explains the wording. How many roofing quotes should I get? Three is a common starting point, but they must cover the same scope. See also how to compare builder quotes and how to compare contractor estimates.

Red Flags When Hiring a Roofer
- No written quote, or one with vague scope
- Cash-only demands
- A large upfront deposit with no stages
- No address, no insurance details or no proof when asked
- Pressure to accept a “today only” price
- Unsolicited door-knocking after a storm
These are reasons to pause and ask questions, not proof that a roofer is dishonest. Roofing quote red flags matter most when several appear together.
How to Choose a Roofer: A Simple Process
How to choose a roofer is easier with a process. Hiring a roofer UK homeowners often rush after a leak or storm, which is when mistakes happen. Slow down where you can:
- Write down the work you want, including roof areas, covering and any extras.
- Ask at least three roofers to visit and quote against the same specification.
- Request itemised written quotes, then ask follow-up questions in writing.
- Check insurance, guarantee and any trade body claims yourself.
- Compare scope, not just price, using the table above.
- Confirm the final contract before paying a deposit.
If you are in a hurry because of a leak, ask about a temporary repair while you take time over the full replacement. A rushed decision rarely produces the best value.
How to Check a Roofer Before Hiring
How to check a roofer is legit UK buyers can start with the basics: proof of public liability insurance, a written guarantee, references and examples of past work. Then check any trade body claims yourself.
- NFRC: a roofing trade association. It says members pass an inspection before joining and are inspected every three years. See choosing a roofing contractor on its site and use its member search to confirm a company.
- TrustMark: described on its own site as the UK’s government-endorsed quality scheme for work in and around the home. Use its Find a Trader tool to confirm a registration.
- Guarantees: NFRC explains that a contractor’s workmanship guarantee differs from an insurance-backed guarantee. Ask which one you are being offered and who stands behind it.
NFRC / TrustMark roofer meaning: membership suggests a roofer has met a scheme’s requirements. It does not guarantee the quality of any particular job, so still compare the written scope.
10 Questions to Ask Every Roofer
- Is scaffolding included, and for how long?
- Are waste removal and skip hire included?
- Which covering, battens and membrane will you use?
- How are timber repairs assessed and priced?
- Are leadwork and chimney work included?
- Is VAT included?
- What deposit do you need, and when are stage payments due?
- Can I see proof of insurance?
- What guarantee do you give, and who backs it?
- How long will the job take, and what happens if it overruns?
Payment Terms: How Much Deposit Is Normal?
There is no single figure that suits every job. Ask what the deposit pays for, whether payments are tied to completed stages and when the final payment falls due. Put the terms in the contract and check them against general consumer guidance. Our post on how much deposit a builder should ask for explains what to look for.
What Happens If the Roof Needs Extra Work Mid-Job?
Stripping a roof can reveal damaged battens, rafters or other timber. This is one of the most common reasons a final bill rises, and it is not always improper. The question is how it is handled. Before you sign, ask how the roofer will tell you about extra work, how it will be documented with photographs, and how it will be priced. Agree any variation in writing before the work goes ahead. Our guide to provisional sums in builder quotes explains why allowances need clear terms.
Roofing Contract: What to Include
A written agreement should confirm the scope, named materials, price, VAT, payment stages, start date, duration, how variations will be agreed and the guarantee. Re-roofing usually involves building regulations, so ask who handles that. The Planning Portal says approval is needed in most re-roofing situations.
