$0-$500K (Year 1-2): - Owner + 1-2 crews, 1 admin - Focus: residential re-roofs, storm damage - Marketing: door knocking after storms, Google Business Profile, yard signs - Software: JobNimbus or AccuLynx for CRM + job tracking
$500K-$2M (Year 2-4): - 3-5 crews, dedicated sales rep, office manager - Add commercial/multi-family - Insurance restoration becomes major revenue (40-60%) - Marketing: SEO, Google Ads ($15-40/click for "roofing contractor near me") - Hire production manager — owner exits daily field work
$2M-$5M+ (Year 4-7): - 8-12 crews, sales team, project managers - Service department (repairs, maintenance contracts) - Manufacturer certifications (GAF Master Elite, Owens Corning Platinum) - Expansion: adjacent markets, additional service areas - Consider franchise model or acquisitions
