Getting work done on your roof is one of the more stressful home maintenance decisions you’ll face. It’s a high-cost job, the results are largely hidden from plain view, and most homeowners simply don’t know enough about roofing to challenge what they’re being told.
That gap in knowledge is exactly where rogue traders operate.
How Do Roofers Rip You Off in the UK?
The roofing industry has a well-documented problem with unscrupulous traders, and the tactics used tend to follow recognisable patterns. One of the most common is the unsolicited knock at the door, often from someone claiming they “noticed some damage” while working nearby. This is a classic opener used to create urgency where none exists, and it should immediately put you on your guard.
Another widespread tactic involves quoting a low price to secure the job, then inflating the final bill with unexpected add-ons once the scaffolding is already up and the roof is partly stripped. At that point, many homeowners feel they have no choice but to agree. Recognising these tactics upfront is the single most effective defence you have.

How to Spot a Dodgy Roofer Before They Start Work
A genuine, reputable roofer is not difficult to identify if you know what to look for. They will provide a detailed written quote, give you time to compare it with others, and won’t pressure you into making a decision on the spot.
Red flags include requests for large cash payments upfront, an unwillingness to provide a written contract, no fixed business address, and vague answers about what exactly the work involves. Any roofer who insists you need to decide today, or who won’t give you documentation, is not a roofer you want on your roof.
| Warning Sign | What It Could Indicate |
|---|---|
| Unsolicited door knock | Potential rogue trader |
| Cash-only payment requested | No paper trail, VAT evasion |
| No written quote provided | Dispute risk, price inflation |
| No proof of insurance | You bear liability for accidents |
| Pressure to decide immediately | High-pressure sales tactic |
| No fixed business address | Difficult to pursue if problems arise |
How to Not Be Scammed by a Roofer: Vetting and Verification
Doing a little homework before hiring can save you a significant amount of money and stress. Start by checking whether the roofer is a member of a recognised trade body such as the National Federation of Roofing Contractors (NFRC), which operates a vetting scheme for member companies and requires them to hold valid public liability insurance.
Beyond trade body membership, ask for references from previous customers and take the time to actually contact them. Online reviews are useful but easy to manipulate; speaking directly to a past client gives you a much clearer picture of how the company operates and whether they did what they said they would.
Getting Multiple Quotes and Understanding What You’re Paying For
Never accept the first quote you receive for any roofing work, regardless of how reasonable it sounds. Getting at least three quotes is standard practice, and it gives you a realistic sense of the market rate for the job in your area.
When reviewing quotes, look for a breakdown of materials, labour, and any additional costs such as scaffolding or waste disposal. A quote that simply states a single lump sum with no detail is a problem; it gives you no way to assess whether the materials being used are appropriate or whether the labour costs are fair.
| Type of Roofing Job | Typical UK Cost Range (2024) |
|---|---|
| Tile replacement (per tile) | £15 to £40 |
| Full re-roof (semi-detached) | £5,000 to £12,000 |
| Ridge tile repointing | £300 to £700 |
| Flat roof replacement (garage) | £1,500 to £3,500 |
| Chimney repointing | £400 to £900 |
| Roof inspection | £100 to £250 |
How to Not Get Ripped Off by a Contractor: Contracts and Payments
This advice applies equally whether you’re hiring a roofer, a builder, or any other tradesperson: never pay in full before the work begins. A reasonable deposit of between 10% and 25% is standard for larger jobs, but anything more than that before a single tile has been touched is a serious risk.
Insist on a written contract that specifies the scope of work, the materials to be used, the agreed price, the payment schedule, and a projected completion date. Paying by card rather than cash also gives you additional consumer protections under Section 75 of the Consumer Credit Act 1974, which can be valuable if a dispute arises.

Protecting Yourself During and After the Work
Once work has started, don’t assume everything is going to plan simply because the roofer turns up each day. Ask to see any materials before they’re installed, particularly if the quote specified a particular brand or type of tile, and take photographs at each stage of the work.
When the job is complete, don’t make the final payment until you’ve had the chance to inspect the work properly. If any defects are visible or if the work doesn’t match what was agreed in the contract, raise this in writing before paying the remaining balance. Reputable roofers will stand behind their work; those who disappear the moment the final payment clears are the ones who were never worth hiring in the first place.
How to Not Get Ripped Off by a Roofer: What to Do If Things Go Wrong
If you find yourself in a dispute with a roofer after the work is complete, your first step should be to raise the issue in writing directly with the company. Keep copies of all correspondence, photographs, and your original contract, as these will be essential if the matter escalates.
If the roofer is an NFRC member, you can raise a formal complaint through their Alternative Dispute Resolution (ADR) scheme, which provides an independent route to resolution without going to court. For more serious cases involving financial loss or fraud, Trading Standards and Action Fraud are the appropriate bodies to contact. The key lesson throughout this entire process is the same one that applies before the work even begins: documentation, verification, and caution are your most reliable tools.

How to Not Get Ripped Off by a Roofer: Frequently Asked Questions
The most common method is inflating material costs or adding unexpected charges after work has begun, when the homeowner feels unable to walk away. Getting an itemised quote upfront is the most effective way to prevent this.
A deposit of between 10% and 25% is reasonable for larger jobs, but you should never pay more than this before work begins. Avoid any roofer who demands 50% or more of the total cost as a deposit.
The National Federation of Roofing Contractors (NFRC) is the UK’s largest roofing trade body, and membership requires companies to meet professional standards and hold valid insurance. Hiring an NFRC member significantly reduces the risk of poor workmanship or disputes.
It is generally inadvisable, as unsolicited door-knocking is a recognised tactic used by rogue traders who rely on pressure and urgency to secure work. Always research any tradesperson independently before agreeing to hire them.
A proper roofing contract should clearly state the scope of work, the specific materials to be used, the agreed total price, the payment schedule, and an expected completion date. Anything less leaves you exposed in the event of a dispute.
Yes, paying by credit card gives you additional protection under Section 75 of the Consumer Credit Act 1974 for purchases over £100, meaning your card provider shares liability with the trader if things go wrong. This protection does not apply to debit card payments.
A quote significantly lower than others you’ve received may indicate that inferior materials are being proposed or that additional costs will be added later. Always ask the roofer to explain what is included in a low quote before accepting it.
A rogue trader is someone who operates dishonestly, typically by overcharging, performing substandard work, or disappearing before a job is completed. In roofing, rogue traders often target elderly or vulnerable homeowners with unsolicited visits.
Yes, you should contact your local Trading Standards office through GOV.UK and report the matter to Action Fraud if money has been taken dishonestly. Keeping documentation such as contracts, receipts, and photographs will strengthen any complaint.
You should obtain a minimum of three quotes to give yourself a realistic sense of the going rate for the work in your area. Comparing multiple quotes also makes it easier to identify any that are unusually high or suspiciously low.
Most routine repair and maintenance work does not require planning permission, but if you live in a listed building or a conservation area, restrictions may apply. You can check the relevant rules using the Planning Portal.
Raise the issue in writing immediately and give the roofer a formal opportunity to return and complete the work within a specified timeframe. If they fail to respond, contact Trading Standards and, if the roofer is an NFRC member, raise a complaint through their dispute resolution scheme.
A workmanship guarantee is a positive sign, but its value depends entirely on the company still being in business when you need to make a claim. Always check how long the company has been trading and whether the guarantee is backed by an independent warranty provider.
Photograph the condition of the roof before work begins, the materials as they are delivered, progress at each stage of the job, and the finished result. These images serve as crucial evidence if a dispute arises over the quality or scope of the completed work.
