How to Vet a Roofer in Europe: The Trade Scammers Love Most

Roofing has the widest gap of any trade between the professional and the dangerous, and it is the one scammers love most. The reasons are structural: a roof problem is invisible from the ground, expensive to fix, and feels urgent - exactly the conditions in which people hand cash to a stranger. The doorstep roofer who 'was working nearby and noticed a few slipped tiles' is a constant across every European market, and the pitch barely changes from Manchester to Malaga.

This guide is how to tell a real roofer from the person knocking on your door. It sits alongside our rundown of the top contractor scams targeting European homeowners, where the doorstep roof job is a recurring star.

Never hire the person who knocks

The single most reliable rule in roofing is that you approach the roofer, not the other way round. The unsolicited caller who has spotted a problem you cannot see, needs to start today, wants cash, and warns that your chimney is about to come down is running the oldest script in the trade. Real roofers have more work than they can handle and do not tout door to door. If someone knocks, thank them, take nothing on trust, and get an independent opinion.

Make them show you the actual problem

A professional roofer proves the fault before quoting to fix it: photos from the roof, drone footage, or evidence from inside the loft where you can see daylight or water staining. A scammer shows you a generic photo of 'a' damaged roof, or simply insists it is bad up there where you cannot look. Ask to see your roof, on your phone, before you discuss money. If the evidence does not exist, neither does the problem - or the roofer.

The checks that matter

• A registered legal entity and a valid VAT number tied to the name on the quote - the same first test as any trade.
• Liability insurance that explicitly covers work at height, which is where roofing injuries and damage happen.
• References to roofs done at least two or three winters ago - a roof's defects show up after weather, not on handover day.
• A written warranty that separates materials cover from workmanship cover, and says who honours each.
• Membership of a national roofing federation or a manufacturer-approved installer scheme, where one exists.

Scaffolding is a sign, not an upsell

Working at height is regulated across Europe, and a firm that turns up to a full roof job planning to free-climb or balance on a ladder is cutting the very corner that gets people hurt and produces careless work. Proper access - scaffolding or a secured system - is a cost a real roofer builds in, not padding. Its absence on anything beyond a minor repair is a warning about how the whole job will be done.

Beware the 'coating' upsell

A common half-scam is the roof 'coating' or 'sealant' sold as an alternative to a real repair or re-covering. On a roof that genuinely needs new tiles, flashing or underlay, a painted-on coating is money spread over a problem that keeps moving. Some coatings have niche legitimate uses, but as a blanket fix pushed by a cold caller, treat it as a red flag rather than a bargain.

Quotes and payment

Insist on a written, itemised quote that names the materials and the access method, not a lump sum scribbled on a pad. Keep the deposit modest, stage payments against work done, and if you can, hold a small retention until the roof has been through a spell of proper weather. A roofer confident in the work will not object to being paid as it proves itself.

The red flags, in one place

• An unsolicited doorstep visit, especially with urgency and a cash request.
• No evidence of the actual fault beyond 'trust me, it's bad up there'.
• No insurance covering work at height.
• A plan to work off ladders on a full roof job, with no proper access.
• A 'coating' pitched as a cheaper alternative to a genuine repair.
• No written warranty, or one that blurs materials and workmanship.
• Pressure to pay cash, up front, today.
