Solvo Index scored 3 commercial roofing companies serving Brandon. Every company holds a Florida contractor license checked on DBPR and carries a confidence tier so you can weigh the score against how well documented it is.
Collis Roofing is the Verified pick at 76.9, just behind Stronghold Roofing's 77.0 on raw score, because Verified companies sort first. Collis holds Florida license CCC058022, active through August 2028, with 26 years on record, 5 of 14 commercial services, a 20-year workmanship and material warranty, and a 4.4 rating from 163 Birdeye reviews. The next 2 companies are ranked on the same six-category rubric using publicly sourced evidence.

The service list confirms 5 of 14. Local or national: Regional.
Weaknesses: The about page says Collis was founded in 1994. The DBPR licensure date is 08/01/2000, which is later, so Track Record uses 26 years from that date.

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.
