How to Choose a Roofer in the UK: 10 Questions to Ask Before You Hire

Quick answer: To choose a good roofer in the UK, check that they hold public liability insurance, belong to a recognised trade body (such as NFRC, TrustMark or the Competent Roofer scheme), give an itemised written quote, offer a written guarantee, and have verifiable local reviews and past work. Avoid anyone who cold-calls, demands a large cash deposit or pushes you to decide on the day. The ten questions below cover everything worth asking before work begins.

Why Choosing the Right Roofer Matters

A roof protects the structure, insulation, electrics and everything inside a home, so poor workmanship rarely stays a small problem. A badly fitted flashing, a skipped underlay or a rushed ridge can cause leaks that surface months later, long after the roofer has left.

The roofing trade also attracts rogue traders, particularly after storms. Cold callers claiming to have "spotted loose tiles" or offering a "special price today" are a well-known warning sign, and Trading Standards regularly warns homeowners about them. Asking the right questions up front separates reliable contractors from risky ones.

The 10 Questions to Ask Before You Hire a Roofer

1. Are You Insured?

Ask for proof of public liability insurance, ideally at £2 million or more. This covers damage to your property or neighbouring properties, and injury to third parties, if something goes wrong.

Also ask whether the roofer carries employers' liability insurance if they use staff or subcontractors. Request a copy of the certificate and check the expiry date. A reputable roofer will provide it without hesitation.

2. Which Trade Bodies or Accreditations Do You Hold?

Membership of a recognised scheme shows that a roofer has been vetted and is held to a standard. Well-known options include:

• NFRC (National Federation of Roofing Contractors): the main UK roofing trade body, with insurance-backed guarantees for members.
• Competent Roofer scheme: allows registered roofers to self-certify certain work under Building Regulations, saving homeowners building control fees.
• TrustMark: the government-endorsed quality mark for trades working in and around the home.
• Federation of Master Builders (FMB) and Which? Trusted Traders: vetting schemes that check references and complaints history.

Verify membership on the scheme's own website rather than relying on a logo on a van or flyer.

3. Can You Give Me a Written, Itemised Quote?

A reliable quote is more than a single figure. It should list:

• The scope of work, room by room or section by section
• Materials, including brand, type and specification
• Labour costs
• Scaffolding, waste removal and VAT
• Start date, estimated duration and payment terms

Get at least three quotes and compare like for like. A much lower price often signals thinner materials, missing underlay or work that will need redoing. A vague quote scribbled on a notepad is a red flag.

4. What Materials Will You Use, and Why?

A good roofer explains the reasoning behind their choices, rather than just naming a product. For a pitched roof, that may mean concrete or clay tiles, natural slate, breathable membrane and battens of the correct grade. For a flat roof, it may mean EPDM, GRP, single-ply or torch-on felt, with the right insulation build-up beneath. Homeowners who want to understand how each covering performs before speaking to contractors can read this guide to the different types of roofs in the UK, which covers lifespan, suitability and typical use 

Ask whether materials carry manufacturer guarantees, and whether the roofer is an approved installer for that product. Some manufacturer warranties are only valid when installed by approved contractors.

5. What Guarantee Do You Offer?

Ask for guarantees in writing, covering both workmanship and materials. Typical workmanship guarantees range from 5 to 10 years, with longer periods on some manufacturer-backed systems.

The key question is what happens if the roofer stops trading. An insurance-backed guarantee, such as those offered through NFRC members, protects you even if the company folds. A guarantee from a business that no longer exists is worth very little.

6. Do You Handle Building Regulations and Permissions?

Some roofing work needs approval, particularly new extensions, re-roofing that changes insulation levels, and work on listed buildings or in conservation areas. Ask whether the roofer will:

• Advise on Building Regulations (Approved Documents L, C and B)
• Notify building control or self-certify through the Competent Roofer scheme
• Check whether planning permission is needed for changes to shape, height or materials

A roofer who dismisses these questions may leave you with unapproved work, which can cause problems when selling the property.

7. Who Will Actually Be Doing the Work?

Some firms win the job and subcontract it to others. That is not automatically a problem, but you should know who will be on your roof. Ask:

• Will the work be done by employees or subcontractors?
• Who is the site supervisor, and how can they be contacted?
• Who is responsible for quality control and tidying up?

Also ask how the roofer manages safe working at height, including scaffolding, edge protection and compliance with HSE guidance. Safe working practice usually reflects overall professionalism.

8. Can I See Examples of Your Previous Work and Customer Reviews?

Experienced roofers are proud of their work and happy to show it. Ask for:

• Photographs of completed projects similar to yours
• Recent reviews on Google, Checkatrade, Trustpilot or similar sites
• References from past customers you can phone
• The address of a local job you can drive past

Read the pattern of reviews, not just the rating. Consistent comments about communication, tidiness, punctuality and aftercare are more meaningful than a handful of generic five-star scores. Beware of businesses with only a mobile number, no verifiable address and no online history.

9. How Do You Want to Be Paid?

Payment terms reveal a lot. Reasonable arrangements include a small deposit to secure materials, with staged payments tied to progress and the balance due on completion and your satisfaction.

Warning signs include:

• A demand for full payment upfront
• Cash-only payments with no invoice
• Pressure to pay a large deposit before any materials are ordered
• Reluctance to provide a receipt

Where possible, pay by debit or credit card or bank transfer, which creates a paper trail. Payments over £100 and up to £30,000 made by credit card may also give additional protection under Section 75 of the Consumer Credit Act 1974.

10. What Happens If There's a Problem or the Weather Changes?

Roofing is weather-dependent, and delays happen. A professional roofer plans for this and explains:

• How the roof will be protected or sheeted if rain stops work mid-job
• How delays will be communicated
• What the process is if you are unhappy with any part of the work
• How snagging, defects and aftercare are handled

Ask for a clear start date and expected finish date in writing. Reliable contractors are honest about the risks rather than promising the impossible.

Red Flags to Walk Away From

• Cold calls or doorstep offers, especially after a storm
• "Today only" discounts and high-pressure selling
• No landline, business address, insurance or accreditation
• Quotes that are far below everyone else's
• Refusal to provide a written, itemised quote
• Requests for large cash deposits
• Scare tactics about "dangerous" roofs without photo evidence
• No guarantee, or a vague promise that isn't written down

If a contract is signed at your home, you normally have a 14-day cooling-off period under the Consumer Contracts Regulations 2013, unless you request work to start sooner in writing, so understand what you are agreeing to before signing.

A Simple Checklist Before Signing

1. Three itemised written quotes compared like for like
2. Proof of insurance and accreditation, verified independently
3. Written guarantee covering workmanship and materials
4. Clear start date, finish date and payment schedule
5. Agreement on scaffolding, waste removal and clean-up
6. Confirmation of Building Regulations or planning requirements
7. A named contact on site

FAQs

A small deposit, typically for materials, is common. Avoid paying large sums upfront, and tie further payments to progress and completion.

It is best to avoid it. Unsolicited doorstep offers, especially after bad weather, are a common tactic used by rogue traders. Choose a roofer you have researched yourself.

Public liability insurance is essential, ideally £2 million or more, and employers' liability insurance if they have employees. Ask for certificates and check the dates.

There is no legal licence required to work as a roofer in the UK, which is why accreditation schemes, insurance and references matter so much.

Workmanship guarantees commonly run from 5 to 10 years, with longer manufacturer-backed warranties on some products. An insurance-backed guarantee offers the best protection if the roofer stops trading.

Raise the issue in writing first and give the roofer a chance to put it right. If unresolved, contact the trade body or accreditation scheme they belong to, and seek advice from Citizens Advice or Trading Standards.
