How to Find and Vet a Roofing Contractor in Glasgow

In Scotland, roofing contractors don't require a single national license in the same way electricians or plumbers do. However, reputable roofers should hold certification from recognized bodies such as the Confederation of Roofing Contractors (CRC), the National Federation of Roofing Contractors (NFRC), or be registered with Trading Standards. Check whether your contractor is listed on the NFRC register or holds Federation Membership, which demonstrates they meet set standards for workmanship and customer service.

Demand to see physical evidence of any certifications or registrations before work begins. A legitimate contractor will have no hesitation providing these credentials. If they claim to be certified but can't produce documentation, that's a major red flag. You should also verify they're registered with Companies House if they operate as a limited company—this is a quick check at companieshouse.gov.uk.

All professional roofing contractors in Glasgow must carry public liability insurance (£6 million minimum is standard) and employers' liability insurance if they employ staff. Before signing anything, ask for proof of current insurance certificates. These should cover your property in case of accidental damage, and protect the workers if they're injured on your roof.

Verify the insurance directly with the provider if possible—don't rely solely on a copy provided by the contractor. Check that coverage is active and will remain so throughout your project duration. Many Glasgow homeowners make the mistake of not verifying this, leaving themselves exposed to significant liability if something goes wrong. Request that you be added as a 'noted interest' on their public liability policy for extra protection. If a contractor refuses to provide proof of insurance or the documentation appears outdated, find someone else immediately.

Always obtain at least three written quotes from different contractors. In Glasgow's competitive market, you can expect quotes ranging from £3,000 to £8,000+ for a standard roof repair or replacement, depending on roof size and materials. Cheaper isn't always better—a quote significantly lower than others may indicate cut corners or inexperienced work.

When comparing quotes, ensure each contractor is quoting the same scope of work. Ask whether the price includes scaffolding, waste removal, and whether there's an excess (excess on insurance claims). A detailed written quote should specify materials, timescale, payment terms, and guarantees. Be wary of contractors who insist on cash-only payments or demand the full fee upfront. Standard practice is a deposit (typically 10-20%) upon agreement and the balance upon completion.

Several warning signs should immediately disqualify a contractor. If they pressure you into a decision, avoid them. Legitimate contractors understand you need time to consider quotes. Door-to-door roofers offering 'special deals' or claiming to have 'leftover materials' are classic scam tactics common in Glasgow—never engage.

Be cautious of contractors with no local address or verifiable online presence. Check Google reviews and Which? Trusted Traders status (if applicable), but remember that reviews can be fabricated. If a contractor can't clearly explain their process or guarantees, or becomes defensive when you ask for references, these are serious concerns. Additionally, avoid anyone who suggests your roof needs urgent work without a clear structural reason or who requests cash payments only.

Roofing work in Scotland should come with a minimum 10-year workmanship guarantee, ideally 12-15 years. This covers defects in the contractor's work, separate from material warranties (which are typically 25-50 years depending on the material). Get this guarantee in writing and confirm whether it's transferable if you sell your home.

If you're claiming on your home insurance for roof damage, be aware of your excess—the amount you'll pay toward a claim. Typical roofing excess in Glasgow ranges from £250 to £1,000. Some contractors may offer to absorb part of the excess as a selling point, but verify this is formal and documented. Always inform your insurer before roof work begins, especially if storm or weather damage is involved, to ensure your excess is clear and you understand what's covered.
