# New Roof Installation Trade Body Accreditation

The main UK trade bodies overseeing roof installation include the National Association of Roofing Contractors (NARC), the British Flat Roofing Council (BFRC) for flat roofs, and membership with schemes like the Federation of Master Builders (FMB) or the Guild of Master Craftsmen (GMC). These bodies set standards for workmanship, health and safety compliance, and professional conduct. Additionally, many roofers hold certifications from manufacturers such as Marley, Kingspan, or GRP specialists, which indicate they have been trained to install specific products correctly. Membership with Trading Standards Approved trader schemes or certification bodies like Checkatrade also provides verification of credentials. Understanding these accreditations is important because they demonstrate that a contractor has met industry standards, carries appropriate insurance, and operates within a regulated framework.

To verify a provider's credentials, ask for documentary evidence of their accreditation before obtaining a quote. You can cross-reference any claimed membership directly with the relevant trade body's website, as most publish searchable directories of registered members. Check whether they hold appropriate insurance, particularly public liability and employer's liability, and request to see their most recent safety record or accreditation certificate. Ask how long they have held their accreditation and whether there have been any disciplinary actions against them, as this information is often publicly available. This verification matters significantly because accredited providers are subject to disciplinary procedures if they breach standards, giving you a formal route for complaint and redress beyond small claims court. Non-accredited traders offer no such protection, and disputes can be far more costly and time-consuming to resolve.

Accredited roofing providers typically charge 10 to 20 percent more than unaccredited alternatives, though this premium varies depending on the complexity of the job and local market
