How to Choose a Roofer in Tonbridge — 7 Questions to Ask

Roofing is one of the home improvement categories with the highest proportion of rogue traders and poor workmanship. It's an industry with low barriers to entry, work that is done out of sight, and consequences of poor practice that can take years to manifest — by which time the contractor may be untraceable. The good news is that the questions that separate a reliable roofer from an unreliable one are simple and consistent. Here are seven of them.

1. Are You Local, and Can You Show Me Evidence?

Genuinely local roofers — those based in or immediately around Tonbridge — have something to lose from poor work. Their reputation is local, their repeat business is local, and unhappy customers are in a community they work in every day. A contractor travelling from 50 miles away has no such stake. Ask where they're based and how long they've been operating in the area. Request the addresses of two or three local jobs completed in the last 12 months that you can drive past. A confident, established local roofer will provide this without hesitation.

NFRC registration: The National Federation of Roofing Contractors requires all member companies to carry a minimum £2m public liability insurance, employ trained operatives with NVQ or equivalent qualifications, and operate a complaints procedure. Checking NFRC membership at nfrc.co.uk takes 30 seconds and confirms a contractor meets these minimum standards. Source: NFRC Membership Standards, 2024

2. Are You NFRC Registered?

The National Federation of Roofing Contractors (NFRC) is the UK's largest roofing trade body. NFRC membership requires contractors to demonstrate adequate public liability insurance, relevant technical qualifications, and compliance with industry standards of workmanship. It's not an absolute guarantee, but it's a baseline filter that eliminates the most casual operators. You can verify NFRC membership on the NFRC website — membership numbers can be fabricated on websites.

3. Can You Provide Written Public Liability Insurance Evidence?

Any roofer working on your property should carry public liability insurance of at least £1 million — ideally £2–5 million. This protects you if a roofer damages your property or injures someone during the works. Ask for the certificate (not just a verbal assurance) and check the policy hasn't expired. If a roofer won't provide insurance evidence, do not allow them on your roof.

4. Do You Provide a Written, Itemised Quote?

A verbal quote, or a quote that simply says "re-roof your house: £X," is not useful and is not a contract. A proper written quote should specify, as a minimum:

• The specific materials to be used (tile brand, profile, colour)
• The lead specification for valleys and flashings (Code 4, Code 5)
• Whether new breathable membrane is included
• Whether scaffold is included and how it will be erected
• How rotten timber discovered during strip will be handled and what it will cost
• The workmanship guarantee period

A written quote is a document you can refer back to, pursue under contract if the work isn't done to specification, and use as evidence in a dispute. A roofer who is reluctant to put things in writing is one to avoid.

5. What Guarantee Do You Offer, and Is It in Writing?

The industry standard for a reputable roofer is a 10-year workmanship guarantee on new roofing work. This is separate from the manufacturer's product guarantee on the tile or membrane — it covers the quality of the installation itself. Ask for the guarantee in writing as part of the contract, and check that it's signed. A verbal "oh we guarantee all our work" is not enforceable.

6. Can You Provide Recent Local References?

Google and Checkatrade reviews are a reasonable proxy but they can be gamed. Direct references — homeowners in Tonbridge and the surrounding area who have had roofing done in the last year and are willing to speak to you — are harder to fabricate. Ask for two or three references. Most homeowners are happy to take a 5-minute call about a good experience with a tradesperson. If no references are available, ask why.

7. What's the Payment Schedule?

Legitimate roofing contractors typically ask for a small deposit (10–20%) on order of materials for large jobs, with the balance on satisfactory completion. Never pay the full amount upfront. Payment in full before work starts removes most of your leverage if the work isn't completed or is done poorly. Payment in cash with no receipt removes your paper trail entirely. Both are red flags. A bank transfer on a documented invoice is the correct method for any significant roofing job.

Red Flags: When to Walk Away

In addition to failing the questions above, these specific patterns are known indicators of unreliable or dishonest operators in Tonbridge and Kent:

• Cold calling at your door, claiming to have been working nearby and "noticed" a problem with your roof
• Urgency pressure — insisting the repair must be done today and that prices increase after this visit
• Refusal to provide a written quote or contract
• Demand for full payment upfront, especially in cash
• No local presence, no verifiable address, no registered business

If you're uncertain about any of these, the simple step of checking a roofer's details on Companies House (for limited companies) or via a local trade body is 10 minutes well spent.
