What a Good Roofing Quote Should Include Before You Sign

A good roofing quote is only comparable if it covers exactly the same work as the others on your kitchen table. You must check what is included and what is left out before you look at the total price. Scaffolding, waste removal and VAT are often missing from a roofing quote, meaning two prices that look different may actually be for completely different jobs.

Why prices vary and why a quote is not an estimate

When you ask different roofers to look at the same problem, they will often suggest different solutions. One roofer might suggest a small patch repair to fix a leak, while another might tell you that the entire roof is failing and needs replacing. A pitched roof is the traditional sloping roof found on most UK houses, while flat roofs are common on extensions. Identical roofing work can vary by 30 to 50 per cent between firms, according to published 2026 quote advice.

Small repairs are usually a fixed price or a day rate, while larger work is priced per square metre plus access. Prices are typically higher in London and the South East. However, the biggest difference in pricing comes down to the legal status of the document you are holding.

According to Citizens Advice, a quote is a fixed price for the job. A written quote should also say when the price can go up, for example if you agree to extra work. A fixed price gives you more certainty than an estimate before the job begins.

An estimate is just a rough guess of what the work might cost. The final cost could be higher once the roofer actually starts the work. Always ask for a written quote rather than an estimate to protect yourself from unexpected bills.

The details every roofing quote should show

A single total figure written on the back of a business card is not a proper quote. You need a detailed breakdown so you know exactly what you are buying. Citizens Advice states that a written quote should show several specific details:

• A fixed total price rather than a daily rate
• A breakdown of all the work and the materials needed
• Separate costs for each material and part of the work
• How long the price is valid for
• Whether the price includes VAT
• When the price can go up, for example if you agree to extra work

A complete roofing quote includes an itemised scope covering the removal of the old roof, the new underlay, the timber supports, the outer covering and the waterproofing at the joints. This breakdown protects you if a dispute arises about what was actually agreed.

The table below shows the key stages a pitched roof replacement quote should detail and why each step matters.

A quote that lists these stages separately is easier to compare than one lump-sum figure. Knowing exactly what each line means helps you spot where corners might be cut.

Scaffolding, waste and other items often left off

Some roofers leave essential items off their initial quote to make their price look more attractive. Scaffolding is often a separate and significant line on a quote. Access can be the biggest single cost driver in roofing, as working at height requires safe platforms.

Typical 2026 prices put scaffolding at £800 to £2,000 on a typical house, and local quotes will vary. A quote that omits it will balloon later, so always check if it is included. Our guide on this site has more detail on scaffolding costs for roof work.

Waste removal is another significant cost that is not automatically included. Stripping a roof creates a lot of heavy waste. Your quote must state clearly if waste removal, skip hire and disposal or tip fees are covered.

A good quote will also list possible extras that might be needed once the job begins. These include gutter repairs or replacement, fascia and soffit work, chimney pointing or leadwork, loft insulation or ventilation improvements, and replacing rotten timbers on bigger jobs. Fascias are the long straight boards that run along the lower edge of the roof, and soffits are the boards tucked underneath them. Guttering is attached to the fascias. Pointing refers to the mortar joints between the bricks on your chimney.

If you have a flat roof, the quote should mention the timber deck. This is the structural wooden base that the waterproofing sits on. If the deck is rotten from a long-term leak, it must be replaced before any new covering is laid. A warm roof has insulation above this deck, while a cold roof has it between the joists beneath. Upgrading the insulation might be legally required if you are replacing a large section of the roof, so the quote should make clear who is paying for the extra materials and labour.

Materials, insurance and the paperwork to ask for

Vague descriptions of materials are a warning sign. A quote that simply says standard materials gives the roofer permission to use the cheapest products available. Your quote should include named materials, specifying the brand, the tile type and the felt grade.

There is a big difference in price between concrete and clay tiles, or between natural slate and fibre cement slate. On a flat roof, the quote must name the exact system being installed. Flat roof systems include built-up felt which is usually applied with a blowtorch and called torch-on, EPDM rubber, GRP fibreglass, single-ply membranes and liquid coatings.

A complete quote also includes a written guarantee covering the workmanship, plus the manufacturer's materials warranty. A workmanship guarantee means the roofer will return to fix any installation faults, while a materials warranty covers product failures. The roofing guarantees and warranties guide on this site explains insurance-backed guarantees in detail. You should also ask to keep a retention until the job passes a final inspection. A retention is a small percentage of the final bill that you hold back until you are completely satisfied that the work is finished, the roof is watertight and the site is clear.

Before you accept any quote, you must check the firm's insurance. Citizens Advice states the trader should have public liability insurance to cover injury or property damage, and employers' liability insurance for their employees. They also list professional indemnity insurance and contractors' all-risk cover.

If the firm is a member of the National Federation of Roofing Contractors, they must evidence adequate annual cover for employers' and public liability insurance. NFRC members pass an inspection before joining and are re-inspected every three years. You can also look for TrustMark, the government-endorsed quality scheme for work in and around the home. Membership is a good sign, not a guarantee, so always check the scheme's own register.

If your chosen roofer is registered with the CompetentRoofer scheme run by the NFRC, they can self-certify roof refurbishment in England and Wales. With every domestic notification, the homeowner receives a building regulations compliance certificate plus a ten-year insurance-backed guarantee. Otherwise the work goes through council building control or a registered building control approver.

Deposits and how to pay safely

How and when you pay is just as important as the total price. A fair roofing quote will outline clear payment terms before the job begins.

Citizens Advice recommends that if a deposit is unavoidable on a long job, you should not agree to more than 25 per cent. A deposit secures your slot in the roofer's diary and helps cover the initial cost of materials. You should never be asked to pay the full balance upfront.

Staged payments are standard practice for larger jobs. This means you pay a set amount at agreed milestones, such as when the scaffolding goes up, when the old roof is stripped, and when the new tiles are delivered. The final payment should only be made when the job is completely finished.

Pay by debit or credit card where possible, otherwise by bank transfer, and do not pay with cash. Paying by credit card gives you Section 75 protection on purchases over £100 and up to £30,000. This means the credit card company shares liability with the roofer if something goes wrong with the work.

How to compare quotes and spot warning signs

You should never hire the first roofer who knocks on your door. Citizens Advice says you should try to get written quotes from at least three different traders before you decide. To compare them fairly, read through the itemised scope on each document and check the terminology.

The ridge is the peak of a pitched roof, the hip is a sloping external corner, the valley is the internal junction where two roof slopes meet, the verge is the outer edge above a gable end, and the eaves are the lower edges where the gutters sit. If roofer A includes replacing the ridge tiles and valley leadwork, but roofer B does not mention them, you are not looking at like-for-like prices. Go back to roofer B and ask them to price the exact same scope of work as roofer A.

You should encourage roofers to take photos of the defect so you can see the problem yourself. Never climb on a roof or use ladders at height yourself to check their claims. Checks from the ground or from inside the loft are fine, but you must leave the high-level access to the professionals.

A bad quote often reveals a bad roofer. There are several clear warning signs you should look out for before you sign any contract:

• A single one-line total with no breakdown of the work
• Pressure from cold callers who spotted a loose tile from the street
• Being pushed to decide today
• Being sold a whole new roof for a minor local fault
• Claims that roof coating, painting or pressure washing will maintain the tiles
• A verbal guarantee that is worthless if the firm folds
• Demands for cash only or a deposit larger than 25 per cent

Common questions

Do I need building regulations approval for a new roof?

In England, repairing or re-covering a roof does not normally need a building control application if less than 25 per cent of the building envelope and less than 50 per cent of the roof is affected. Above that, approval is needed. Structural alterations, adding 15 per cent or more to the weight, or replacing a glazed conservatory roof with a solid one also require approval. Rules differ in Scotland and Northern Ireland, so you should check with your council rather than guessing.

What happens if the roofer finds rotten timber?

Nobody can see rotten timber until the old covering is off. A good written quote will state clearly how extra work like replacing rotten joists or battens will be priced. If rotten timber is found, the roofer should stop, show you the damage, and provide a fixed price for the extra work before proceeding.

Can I change my mind after signing a roofing quote?

Contracts agreed at home, by phone or online normally carry a 14-day cooling-off period. This gives you the right to cancel without penalty. However, if you ask for the work to start inside that period, for example to fix an emergency leak, you must pay for what has been done up to the point you cancel.

What should I do if the work is poor?

Under the Consumer Rights Act 2015, work must be done with reasonable care and skill. If it is not, you can ask for it to be put right or for your money back. If you have a dispute that you cannot resolve directly with the trader, you should contact Citizens Advice for further guidance.

Next steps

Getting the right paperwork in place takes a little extra time, but it is the only way to protect your home and your money. Before you agree to any roofing work, work through this final checklist:

• Check the document says quote rather than estimate
• Ensure scaffolding, waste removal and VAT are clearly listed
• Confirm the exact brand and type of materials being used
• Ask to see the firm's public liability and employers' liability insurance
• Agree to a deposit of no more than 25 per cent
• Set up payment by credit card or bank transfer, never cash

Comparing detailed written quotes is the safest way to understand what your roof needs and what it should cost. When you are ready to start gathering prices, you can find a roofer near you to inspect your property and provide a full, itemised breakdown of the work required.
