9 red flags that separate cowboys from craftsmen. NFRC checks, deposit rules, and guarantee essentials.
After every storm, unlicensed operators knock on doors across Hackney, Stratford, and Barking offering cheap repairs. They use pressure tactics, demand cash upfront, do substandard work, and vanish without a trace. East London Trading Standards consistently ranks roofing among the top five complaint categories.
The antidote is simple: never hire a roofer who knocks on your door unsolicited. Always get multiple written quotes. Always verify insurance and trade body registration. Always insist on a written guarantee before work begins.
Written quote: Must name materials by specification, itemise every element, state total cost, and be valid for 30+ days. A verbal quote or single-number estimate is not acceptable.
Insurance: £2m minimum public liability (£5m preferred). Ask to see the certificate — not just hear “yes we’re insured.”
Trade body: NFRC (National Federation of Roofing Contractors) or TrustMark registration. Both involve vetting, inspection, and a complaints procedure.
Guarantee: Written, minimum 10 years, specifying what is covered and how to claim. Insurance-backed guarantees provide protection if the company ceases trading.
Reviews: Verified Google reviews from real customers. Check Checkatrade, TrustATrader, and local Facebook groups. Be suspicious of a company with zero online presence.
Deposit: Maximum 10–20% on larger jobs to cover material costs. Full payment upfront is a red flag. Balance due on satisfactory completion only.
After every East London storm, unlicensed operators drive through residential streets in Hackney, Stratford, Barking, and Romford, knocking on doors and pointing at roofs. "I was working on your neighbour's roof and noticed you've got some loose tiles." This is the most common opening line for rogue traders. They offer a quick cheap fix, demand cash payment, do terrible work (or no work at all), and move on to the next victim.
The rule is absolute: never hire a roofer who knocks on your door unsolicited. No legitimate roofing company generates work by cold-calling on residential doorsteps. Every professional roofer has more work than they can handle through referrals, online enquiries, and repeat customers.
Step 1: Search the NFRC member directory at nfrc.co.uk. Type their company name and see if they are registered. NFRC membership involves vetting, site inspections, and ongoing compliance checks.
Step 2: Search the TrustMark register at trustmark.org.uk. TrustMark is a government-endorsed quality scheme for tradespeople.
Step 3: Check Google reviews — not just the star rating, but read the actual reviews. Are they from real local people? Do they mention specific streets and specific jobs? Fake reviews are generic ("great service, would recommend") while real reviews describe actual work done.
Step 4: Ask for the insurance certificate. Not a verbal assurance — the actual document. Check the company name matches, the policy is in date, and the cover level is at least £2 million (ideally £5 million) public liability.
Step 5: Get it in writing. The quote, the guarantee, the payment terms, the materials specification. If any element is verbal-only, it effectively does not exist.
A written quote from a professional roofer should separately list: the work to be done (in plain English, not trade jargon), every material by manufacturer name and specification, scaffolding costs, waste disposal costs, a timber inspection allowance, the total price (inclusive of VAT if the company is VAT registered), payment terms (maximum 20% deposit, balance on completion), guarantee terms (minimum 10 years, in writing), the company's registered address and insurance details, and the quote validity period (minimum 30 days).
If the quote is a single line — "New roof: £6,500" — it is not a quote. It is a number on a piece of paper. Get a proper quote from someone who takes the time to specify the work correctly.

“Poplar flat — roof terrace membrane was pooling and leaking into the flat below. They re-laid the membrane with correct falls, new drainage gullies, and composite deck on top. Problem solved.”
“EPDM rubber roof on our garage. Clean installation, proper drainage, and the 20-year guarantee gives us peace of mind. Half the price of the GRP quote we had from another company.”
“Roof survey before we bought our house in Forest Gate. They found three issues the surveyor missed — rotten valley board, nail-sick slates, and a blocked hopper. We renegotiated the price and saved four grand.”
