Norman Roof Pros provides professional commercial roofing in Norman, OK for residential and commercial properties across central Oklahoma. Commercial low-slope roofs across central Oklahoma fail from hail in a way that is quieter and more expensive than a residential failure. The building keeps operating normally while the assembly underneath gets steadily wet.
The membranes we work with here are TPO and EPDM single-ply and two-ply modified bitumen, and their hail behavior differs meaningfully. A thin membrane laid directly over rigid insulation is the vulnerable combination, because a stone drives the membrane down into the insulation and fractures the reinforcing scrim without necessarily opening a hole anybody can see. Thicker membrane over a cover board resists that markedly better. Thickness and what sits under it decide almost everything.
Which is why we specify a cover board on nearly every reroof: a half-inch high-density gypsum or asphaltic board over the insulation and under the membrane. It is a modest line item that changes how the whole assembly takes an impact, and it improves the fire and wind ratings of that assembly at the same time. On a building that will take hail again, the cover board is the closest thing to a free upgrade on the specification.
Finding hail damage on a membrane requires cutting into it. Infrared scanning locates wet insulation, core samples confirm what the scan found, and neither step is optional on a building where the damage may sit under a surface that still looks continuous. We core on a grid, patch every core the same day, and hand over the moisture map rather than a verbal summary of it. A verbal all clear on a flat roof is not an inspection.
The recurring problem on occupied buildings is penetrations. Every unit added over the years brought a curb, a pipe, a conduit stand or a gas line, and each was flashed by whoever installed that equipment rather than by a roofer. On most buildings we inspect, more than half the open items sit at penetrations no roofing contractor ever touched. We inventory every curb and stand, and price them as their own line.
We schedule around operations rather than around production. Tear-off over a warehouse aisle, a kitchen or a clinic gets sequenced so no section stays open past the day's weather window, and we hold a dry-in target instead of a square-count target. On a building that cannot close, that constraint costs more in labor and it is not negotiable. That is why we quote occupied buildings differently from empty ones.
Our licensed and insured team brings the right materials and equipment to every job — UL 2218 Class 4 impact-rated shingles, SBS-modified rubberized asphalt shingles, ASTM D7158 Class H wind-rated laminates, thirty-six-inch self-adhered valley membrane, ring-shank fasteners in the six-nail zone, 24-gauge standing seam steel with concealed clips — and backs the work with a written workmanship warranty. We serve Norman and nearby communities including Moore, Noble, Lexington, Slaughterville.

Materials, equipment and how we do commercial roofing
The difference between commercial roofing that lasts and commercial roofing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with UL 2218 Class 4 impact-rated shingles, SBS-modified rubberized asphalt shingles, ASTM D7158 Class H wind-rated laminates, thirty-six-inch self-adhered valley membrane, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Norman job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in central Oklahoma means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

The standards behind commercial roofing
Quality here is not a matter of opinion — it is written down. The commercial roofing work we do in Norman follows published industry standards: NRCA publishes the Roofing Manual, the industry's reference for details and slope minimums, and Asphalt Roofing Manufacturers Association sets the shingle application and ventilation guidance the warranties reference. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
