Our read: commercial roofing in Norman

Cleveland County's roofing establishments are mostly very small: 43 of 53 with paid employees have fewer than 5 employees, and the whole group has 243 paid employees (Census, 2023). The county's storm record adds 42 tornadoes and 365 hail reports for 2014 to June 2026. On a commercial bid, ask who will actually be on your roof, how many people the job needs, and whether the company installs membrane systems or mostly shingles.

Can a Norman roofing company with a few employees handle a commercial building?

Some may. We have no data on which establishments take commercial work. The Census count for 2023 shows 43 of the county's 53 roofing establishments with paid employees have fewer than 5 employees. Ask for references on buildings like yours and for the crew size on your job.

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 Norman changes about commercial roofing

Hail of 1 inch or more has fallen near Norman on more days than in most cities we cover. Membranes can be punctured by hail, so ask for an inspection after a hail day, with core samples if the insulation may be wet.

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.

That day brought 19 reports, with the largest from Lake Thunderbird Dam.

A commercial roof laid before May 2020 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 thunderstorm gust was 105 mph, on May 6, 2024.

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.
