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 Houston has 301 roofing companies with payroll, higher than 100% of the cities we cover. 25 local roofers are listed, 19 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 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.
A large share of Houston'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.

April has the most reports, 49 of 169. Reports run from January to December.
The largest stone in NOAA's record for Harris County fell on April 19, 2015: 2.75 inches, about the size of a baseball.
That day brought 8 reports, with the largest from Korville.
A commercial roof laid before April 2015 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 January 24, 2023 and stayed on the ground for 23.3 miles.
The strongest thunderstorm gust was 104 mph, on May 16, 2024.
| Date | Largest hail | Reports | Where |
|---|---|---|---|
| April 19, 2015 | 2.75 in, a baseball | 8 | Korville |
| May 9, 2019 | 2.5 in, a tennis ball | 12 | Hermossey |
| January 8, 2016 | 2.5 in, a tennis ball | 4 | Bellaire |
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 25 listed, license-checked first. They are based in Houston (5), Austin. We do not tag companies by service, so ask each one about commercial roofing.
