Our read: commercial roofing in Denver
How do I vet a Denver roofer for a commercial building?
Size alone does not settle it. In Denver County, 78 of 103 roofing establishments with paid employees have fewer than 5 employees (Census, 2023), and that count does not show who does commercial work. Ask which buildings of your type the company has roofed recently, how many workers will be on site, and which company stands behind the membrane warranty.
What commercial roofing is, and what to ask about it
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.
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
Ask each roofer
- How many buildings like mine have you roofed in the last two years?
- Do you scope the whole drainage path or only the wet spot?
- Can you scan or core the roof to see whether the insulation is wet?
- Who holds the membrane warranty, you or the manufacturer?
What Denver changes about commercial roofing
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 Denver'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.

The county's biggest hail days
The largest stone in NOAA's record for Denver County fell on May 30, 2024: 2.75 inches, about the size of a baseball.
That day brought 32 reports, with the largest from Denver Intl Arp.
A commercial roof laid before May 2024 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 June 24, 2015 and stayed on the ground for 2.8 miles.
The strongest thunderstorm gust was 81 mph, on June 6, 2020.
| Date | Largest hail | Reports | Where |
|---|---|---|---|
| May 30, 2024 | 2.75 in, a baseball | 32 | Denver Intl Arp |
| May 8, 2017 | 2.5 in, a tennis ball | 8 | Denver |
| July 15, 2016 | 2 in, a hen egg | 7 | Glendale |
Why this page prints no city price for commercial roofs
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.
