Most roofers are decent tradespeople. But roofing is also the classic doorstep-scam trade — the work is high up where you can’t check it, urgency is easy to invent, and by the time problems show, the van’s number plate is a memory. These are the patterns that come up again and again in Bristol, and the simple habits that defeat them.
The doorstep “passing by” approach
Someone knocks: they were “working on a roof down the street” and noticed your tiles/chimney/ridge are dangerous. Sometimes there’s a grain of truth; usually there isn’t. The tell is the push for immediate action — up the ladder today, cash price, no paperwork. Legitimate roofers with local reputations don’t need to cold-knock. The defence is simple: thank them, close the door, and if you’re worried, book your own inspection from a firm you chose.
The invented emergency
A variant: the scammer gets on the roof (sometimes just to “check for free”), then descends with photos of horrifying damage — occasionally damage they created, more often photos of someone else’s roof. Countermeasure: any genuine finding survives a second opinion. A roofer who objects to you getting one is telling you what their photos are worth.
The disappearing deposit
Large cash deposit demanded “for materials”, then the firm evaporates or the job stalls indefinitely. Reasonable firms have trade accounts with merchants and don’t need hundreds of pounds of your cash before a tile is lifted. Deposits on big jobs should be modest, invoiced, and ideally protected — see our post on insurance-backed guarantees.
The quote that grows on the roof
Work starts at one price and “discoveries” double it, with pressure to approve verbally because “we’re already up here”. Real discoveries happen — the difference is documentation. Photos, a pause, and a revised written figure before continuing is professional; a bigger invoice at the end is not. Agree the change process before work starts.
The habits that make you a hard target
Never commission roof work from someone who initiated the contact. Get written itemised quotes — compare against our cost guide. Pay by bank transfer or card, never cash. Check the firm has a real address and landline. And trust the pattern, not the charm: every scam above depends on speed, so anyone rushing you has answered your question.
