Solvo Index scored 2 commercial roofing companies for new construction in the Lakeland area, which spans Lakeland, Lakeland Highlands, Kathleen, Winter Haven, Haines City, Davenport, Plant City, and 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 leads with a Solvo Score of 76.9 and is the only Verified roofer on this list. Its Florida license, CCC058022, is active through August 2028, and it has 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 company is ranked on the same six-category rubric using publicly sourced evidence.
No company can pay for a higher score. Verified companies sort first. How we score
No company can pay for a higher Solvo Score or a better position. Every company is measured against the same six-category rubric, then sorted by how well its score can be verified.
Evidence Completeness, the share of fields we could independently verify rather than leave blank, sets each company's Confidence Tier: HIGH at 90%+, MEDIUM at 70-89%, LOW below 70%. A company marked Verified carries that tier above HIGH.
A published score never exceeds 97.0, even where the formula computes higher. Every ranked company, including #1, carries at least one published weakness.
Badges are single-fact superlatives among these 2, each tied to one sourced number, never a blended score. Not a competition for #1: a company can hold more than one.

Collis Roofing is the Verified company on this list. License CCC058022 is Current and Active through 08/31/2028. Birdeye lists 4.4 from 163 reviews and splits the count into Google 150 and BBB 12. The Google profile URL was not found. A BBB letter grade is not used as the star rating.
Strengths: Collis Roofing is the Verified company. License CCC058022 is Current and Active through 2028-08-31. The DBPR record prints CCC058022, which scores 5.

Those phrases do not match GAF Master Elite or Owens Corning Platinum Preferred, so those 2-point rows stay empty. The review record used here is 4.4 from 163 Birdeye. 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. TPO, EPDM, modified bitumen, metal, flat or low-slope, inspections, insurance claims help, and skylights or drainage were not named on that page.

Other commercial services and cities within the Lakeland market, same methodology, 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.
