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
The county around Biloxi has 8 roofing companies with payroll, lower than 79% of the cities we cover. 28 local roofers are listed, 4 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.
The county has fewer roofing companies with payroll than most cities we cover, so a commercial job may draw few bidders. Ask early who will bid, and whether nearby companies will travel.
A large share of Biloxi's housing sits outside single-family houses, so flat and low-slope roofs are common. Ask every company about its experience with your type of building, not only with houses.

May has the most reports, 10 of 30. Reports run from January to September.
The largest stone in NOAA's record for Harrison County fell on May 15, 2022: 2 inches, about the size of a hen egg.
That day brought 8 reports, with the largest from Wool Market.
A commercial roof laid before May 2022 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 EF1 on November 1, 2018 and stayed on the ground for 7.22 miles.
The strongest thunderstorm gust was 78 mph, on June 18, 2026.

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.
