Roofers businesses face specific challenges that prevent AI assistants from finding and recommending them.
Roofing is a high-cost trade where consumers fear cowboys — AI reflects this caution by defaulting to verified directories rather than individual roofer websites.
Most roofer websites show before/after photos with no text descriptions, pricing, or material specifications.
Certification (NFRC, CompetentRoofer, TrustMark) is rarely structured in schema — AI cannot verify qualifications from a logo image.
Service pages don't differentiate between emergency repairs, full re-roofs, flat roofing, and fascias/soffits.
What the visible businesses do differently
NFRC or CompetentRoofer membership in schema • Service-specific pricing: emergency leak repair, ridge tile re-bedding, full re-roof per sqm, flat roof replacement • Checkatrade and MyBuilder profiles with project photos and detailed reviews • Material specification pages: slate vs tile vs felt vs rubber EPDM with pros/cons and pricing per sqm
Schema types that matter: RoofingContractor, HomeAndConstructionBusiness, LocalBusiness, Service
National Federation of Roofing Contractors membership is the industry gold standard. Add your membership number to HomeAndConstructionBusiness schema.
Emergency repair (from £150), ridge tiles (from £300), full re-roof (from £5,000), flat roof (from £1,500). Include per-sqm rates for common materials.
These are the directories AI trusts for roofing recommendations. Upload project photos with descriptions for each completed job.
Pages comparing slate vs tile vs felt vs EPDM rubber — cost, lifespan, maintenance. This genuinely helpful content is what AI extracts for 'best roofing material' queries.
Document completed projects with before/after photos, materials used, cost breakdown, and timeline. Add alt text to every image describing the work.
