How to find a reliable roofer in Wales

Roofing is one of the highest-risk trades for homeowner scams and poor workmanship in the UK. In Wales, where Atlantic weather puts roofs under sustained pressure, a bad roofing job can cause serious and expensive water damage within months. This guide explains how to find a genuine, qualified roofer and avoid the most common pitfalls.

Why roofing qualifications matter

Unlike gas or electrical work, roofing is not legally licensed in the UK โ€” anyone can legally call themselves a roofer. This creates a Wild West environment where inexperienced or dishonest operators regularly take money for substandard work.

The main quality indicators are:

NFRC (National Federation of Roofing Contractors) โ€” the UK's largest roofing trade body. Members are vetted, insured, and must adhere to a code of conduct. Check membership at nfrc.co.uk.

CompetentRoofer โ€” a government-approved competent person scheme for roofing. Members can self-certify their own work without local authority inspection. Check at competentroofer.co.uk.

CITB (Construction Industry Training Board) card โ€” shows the roofer has completed formal industry training.

In Wales specifically, many reputable roofing contractors are also registered with Cymru Ceidwaid (Welsh Conservation Contractors) if they work on traditional Welsh slate, which requires specialist knowledge.

How to check a roofer before hiring

Before accepting any quote:

  1. Verify NFRC or CompetentRoofer membership โ€” don't just take their word for it, check the register online.
  2. Check Companies House โ€” legitimate roofing companies are registered. A sole trader operating under their own name is fine; a vague "business name" with no company registration is a warning sign.
  3. Ask for proof of public liability insurance โ€” roofing work can damage neighbouring properties; ยฃ2 million minimum is standard.
  4. Request three references from local jobs completed in the last 12 months โ€” and follow up on them.
  5. Check their physical address โ€” a local base means they're accountable if something goes wrong.

Never let a roofer start work on the day they arrive unsolicited. Legitimate roofers do not cold-call.

Getting quotes: what to include

A professional roofing quote should specify:

  • Exact work scope: which sections of roof, which materials
  • Material specification: manufacturer, product name, and thickness for felt, tiles, slates, or membrane
  • Underlays and battening: replacement vs reuse
  • Flashing: lead, mortar, or sealant โ€” and which is being used where
  • Valley treatment: open cut, closed, or lead-lined
  • Disposal of old materials: skip or recycling
  • Guarantee period: NFRC members typically offer 10-year guarantees on major works

Get at least three written quotes. If quotes vary by more than 25%, ask each contractor to explain what they're including/excluding.

Common roofing scams in Wales

The "we spotted a problem" cold call โ€” men in a van stop outside your house claiming to have seen loose slates or dangerous flashing while working nearby. They show you a tile (sometimes from your own roof, sometimes not). Never hire from a cold call.

Pointing scams โ€” inflated prices for "repointing" ridges or chimney stacks, often done with the wrong mortar which fails within a year.

Felt-only repairs โ€” applying a bituminous felt coat over a failing flat roof rather than full replacement. This delays the inevitable by 2โ€“5 years but the underlying failure worsens.

Pressure-washing offers โ€” power-washing moss from roofs can dislodge or crack tiles. Moss treatment should use biocide spray, not pressure washing.

Welsh weather and your roof

Wales has some of the highest rainfall in the UK, particularly in the Valleys and mid-Wales. This means:

  • Natural Welsh slate performs exceptionally well in the Welsh climate โ€” it's been used here for 400 years for good reason. Quality reclaimed Welsh slate is preferable to imported alternatives.
  • Concrete interlocking tiles are common in post-war housing and perform adequately, but check for frost damage on older installations.
  • Flat roofs are a weak point in the Welsh climate โ€” modern EPDM (rubber) or GRP (fibreglass) systems significantly outperform felt in wet conditions. If you're replacing a flat roof, insist on one of these modern systems.
  • Guttering and downpipe maintenance matters more in Wales than in drier areas โ€” blocked gutters cause fascia damage and penetrating damp.

Get your roof professionally inspected every 5โ€“7 years, and after any extreme weather event (storm, heavy snow, flooding). Early intervention costs far less than emergency repairs after water has penetrated the structure.
