The commercial hub and the other cities in this market use the same rubric.
Every company is scored 0-10 in six weighted categories against fixed written anchors, using only sourced, dated evidence. Service Capability uses the commercial list of 14. The other five inputs stay on the roofing rules. A company is numbered only when its own site names commercial work and the place, and Florida DBPR shows a current roofing license.
