Signs you need it
- Ponding water after rain on a flat roof
- Open seams or failed flashing at rooftop units and parapets
- Ceiling stains below drains, units or roof edges
- A roof near the end of its warranty, with a lease or sale coming up
Wind gusts of 58 mph or more were recorded on 92 days near Chattanooga, higher than 90% of the cities we cover. 26 local roofers are listed, 5 license-checked.
Commercial roofing covers retail, office, warehouse, church and multi-family buildings. Most of these roofs are flat or low-slope and use single-ply membranes, modified bitumen, built-up roofing or standing seam metal.
Crews, materials and warranties differ from house roofing. A company that is good on shingles may not be the right one for a membrane roof.
Wind gusts of 58 mph or more are recorded near Chattanooga on more days than in most cities we cover. On a membrane roof, ask how edges and parapets are anchored, because wind starts at the perimeter.
The county has more roofing companies with payroll than most cities we cover, so you can compare several bids on a commercial job. Ask each for references on a building like yours.

May has the most reports, 7 of 20. Reports run from March to August.
The largest stone in NOAA's record for Hamilton County fell on March 1, 2017: 1.75 inches, about the size of a golf ball.
That day brought 2 reports, with the largest from Chickamauga.
A commercial roof laid before March 2017 was in place for the largest stone in the record, so ask for a roof survey and keep it with the warranty papers.
The strongest tornado in the record was rated EF3 on April 12, 2020 and stayed on the ground for 12.75 miles.
The strongest thunderstorm gust was 90 mph, on June 7, 2025.

A commercial roof is priced by the building: its area, membrane, insulation, drainage and rooftop equipment. One range per city would mislead.
Ask each company for a written scope and a price per square foot of roof, so bids can be compared line by line.
Estimates for a 2,000 square foot roof, not quotes. How we build them6 of 26 listed, license-checked first. They are based in Chattanooga (6). We do not tag companies by service, so ask each one about commercial roofing.
