# Roof Maintenance Accreditation

The main UK trade bodies overseeing roof maintenance include the National Association of Roofing Contractors (NARC), the Confederation of Roofing Contractors (CRC), and various specialist schemes such as those run by manufacturers like Sika, Firestone, and Marley. Additionally, the Quality Mark scheme offers independent verification of competence, while the British Standards Institution (BSI) accreditation indicates a company meets BS 8601 or other relevant roofing standards. Many roofers also hold Health and Safety Executive (HSE) accreditation, particularly for working at height, and may be certified under CSCS (Construction Skills Certification Scheme). These credentials confirm that a provider has demonstrated technical knowledge, follows industry best practices, carries appropriate insurance, and maintains proper safety standards.

To verify a provider's accreditation, you should ask for their membership certificate or registration number and check it directly on the trade body's website—most publish searchable directories of accredited members. You can also request proof of public liability insurance (typically £6 million minimum for roofing work), employers' liability insurance if they have staff, and certifications for specific systems they use. This verification matters because accredited contractors are bound by codes of conduct, undergo regular training, and must maintain quality standards to retain membership. Unaccredited roofers may be cheaper upfront but offer no formal recourse if work fails, and they may not carry adequate insurance, potentially leaving you exposed to liability if someone is injured on your property.

Accredited roof maintenance providers typically charge 10–25 per cent more than unaccredited alternatives, reflecting their investment in training, insurance, compliance, and accountability measures. This premium is usually justified because accredited work often qualifies for extended warranties, is completed to verified standards, and comes with backup if disputes arise
