Commercial Storm Damage Restoration in Tulsa, OK
When hail or straight line wind moves across the Tulsa metro, the commercial buildings in its path do not all fail the same way. A twenty year old modified bitumen roof over a retail center behaves nothing like a two year old TPO system on a distribution warehouse, and the damage on both is often invisible from the parking lot. That is why storm losses on commercial property get underpaid so often. Nobody documented what actually happened up there.
Decor Roofing and Restoration has handled commercial storm damage across the Tulsa metro since 1987, from our headquarters right here in Bixby. We are a full service commercial restoration contractor, which means the roof, the water that came through it, and the interior reconstruction all happen under one contract with one accountable project team. You are not coordinating a roofer, a water mitigation company, and a general contractor while your tenants are asking when they can reopen.
We are an IICRC Certified Firm, company number 70249741, with certified water damage and fire and smoke restoration technicians on staff. Our inspector is HAAG certified and documents in Xactimate, which is the format commercial adjusters work in every day. Call (918) 382-7663 any time.

How Hail Damages Each Commercial Roof System
Commercial hail damage is not one thing. The membrane or panel on your building determines what the hail did, how quickly it will turn into a leak, and how it needs to be documented for a claim. This is the part most inspections get wrong, because a walk that treats every flat roof the same will miss the failure mode that matters.
TPO and PVC single ply
Hail on a thermoplastic membrane fractures the reinforcing scrim inside the sheet without always breaking the surface. From above it can look like nothing more than a scuff. What has actually happened is that the layer carrying the membrane’s strength has been broken, and the sheet will split along that line under the next thermal cycle or foot traffic. Impact around penetrations and at seam welds is the most urgent, because those are the points already carrying stress.
EPDM rubber
EPDM bruises. The hailstone drives the membrane down against the substrate below and crushes it, leaving a circular mark that is often easier to feel than to see. Where the roof is fully adhered over a hard deck the bruising is worse, because the membrane has nowhere to give. Bruised EPDM frequently holds water out for another season and then fails suddenly, which is why a documented inspection right after the event matters more on rubber than on almost any other system.
Modified bitumen and built-up
On granule surfaced modified bitumen, hail knocks the granules loose and exposes the asphalt underneath to ultraviolet light. The roof does not leak that week. It ages several years in one season instead, because the layer protecting it from the sun is gone. On gravel surfaced built-up roofing the same thing happens with the ballast displaced, and the bare spots show as dark patches across the field. Heavier stones fracture the ply mat itself, which is a repair rather than a cosmetic matter.
Metal panel and standing seam
Metal dents, and a dent by itself is often cosmetic. What is not cosmetic is a fractured protective coating at the impact point, because that is where corrosion starts, and hail striking the fastener heads on an exposed fastener roof, which breaks the seal on the washers. A metal roof that took hail two years ago and is now showing rust streaks below the fasteners is telling you exactly when the damage happened.
Wind and Tornado Damage on Commercial Buildings
Wind damage on a commercial roof almost always starts at an edge. The field of the roof is the strongest part of the assembly. The perimeter, the corners, and anything that sticks up are where uplift pressure concentrates, and that is where a storm finds its way in.
- Membrane uplift and billowing. Once wind gets under a single ply sheet at a loose edge, it peels. A membrane that billowed and reseated can look intact and have fasteners pulled or seams stressed along the whole run.
- Edge metal and coping failure. Loose or displaced coping is both a leak path and a liability concern, because that metal comes off the building and lands somewhere.
- Parapet and wall flashing separation. Wind pulls the membrane away from the parapet and leaves open voids at the top of the wall, which is the single most common source of interior water on a commercial building after a wind event.
- Fastener backout on metal roofing. Panels flex under wind load and work the screws loose over time, and the seal fails before the fastener does.
- Rooftop equipment. HVAC curbs, exhaust fans and condenser units shift under wind and tear the flashing around them. Bent condenser fins are also a documented, covered loss that gets missed constantly.
After a tornado event, the question is structural before it is anything else. We do not put crews on a roof with suspected deck or joist damage until the structure has been assessed. Keep everyone out of the affected sections of the building and call us.
The First 48 Hours: What a Property Manager Should Do
What happens in the first two days shapes the entire claim and most of the final cost. The scope only grows from here, so the goal is to stop the damage and record what it looked like before anything was disturbed.
- Get people out of affected areas and keep them out. Wet ceiling tile and saturated insulation come down without warning, and a compromised structure is not obvious from below.
- Photograph everything before anyone touches it. Interior water, ceiling stains, affected inventory and equipment, and the exterior from ground level. Timestamped photos are evidence. Do not send anyone onto the roof.
- Stop the water where you safely can. Buckets and containment inside, and move what can be moved. Mitigation is a covered expense and failing to mitigate can reduce a settlement.
- Notify your carrier and open the claim. Most commercial policies have a reporting window measured in days, not months. Opening the claim early costs nothing and protects your position.
- Call us at (918) 382-7663 for emergency tarping and board up. Same day response is our standard. Emergency mitigation is documented separately and submitted as part of the claim.
- Get a documented inspection on the roof. Not a walk and a verbal opinion. A written, photographed, system specific condition report is what turns a disputed claim into a paid one.
How a Commercial Storm Claim Differs From a Residential One
Property managers who have handled a claim on their own home are often surprised by how different a commercial loss is. The differences are worth knowing before you are in one.
- The scope is bigger and so is the disagreement. On a large roof, a difference of a few cents per square foot in the settlement is a serious number, so commercial adjusters scrutinise scope far more closely.
- Business interruption and loss of rents are usually in play. Those are separate coverages from the building itself and they run on the restoration timeline, which means delay costs money in more than one place.
- There are more stakeholders. Ownership, property management, tenants, and sometimes a lender all need to be kept informed, and tenant leases may dictate response obligations.
- Replacement cost versus actual cash value matters more. On a large commercial roof the depreciation holdback can be a very large number, and recovering it depends on completing the work and documenting it correctly.
- Code upgrade requirements can be triggered. A commercial reroof may require insulation or attachment upgrades that were not on the original building, and whether the policy covers that depends on the ordinance and law endorsement.
We document all covered damage in Xactimate, meet your adjuster on the roof, and coordinate through the claim. That work is included with any project we complete. We are a restoration contractor, not a public adjuster, so the settlement decision remains between you and your carrier. What we control is that nothing goes undocumented.
Oklahoma Commercial Storm Season and Why Timing Matters
Oklahoma sits in the part of the country that produces the most concentrated hail and wind damage to commercial property in the United States. Around the Tulsa metro the heaviest activity runs from March into June, with a secondary autumn window, and it is normal for a single spring to bring several separate qualifying events.
That creates a practical problem for building owners. Damage from an April hailstorm frequently does not become a leak until July or later, and by then the reporting window on the policy may have closed and the loss date is difficult to establish. Insurers know this. It is one of the most common reasons a legitimate commercial claim gets denied.
The way around it is straightforward. After a significant hail or wind event in your area, have the roof inspected and documented even if nothing is leaking. A dated condition report costs you nothing and establishes exactly what happened and when. If the roof is fine, you have a clean baseline for next season.

FREQUENTLY ASKED QUESTIONS
How soon after a hailstorm should a commercial roof be inspected?
Within 30 days of the event. Most commercial policies have a reporting window measured in days, and hail damage to a commercial membrane frequently does not leak for months. By the time it does, the loss date is hard to establish and the claim window may have closed. A dated inspection right after the storm protects your claim whether or not you end up filing.
Does commercial property insurance cover storm damage restoration?
In most cases, yes. Hail, tornado and high wind are covered perils under virtually all commercial property policies. What varies is coverage for interior damage, business interruption, loss of rents and code upgrades, which depends on your specific policy and endorsements. We document all covered damage in Xactimate and coordinate with your adjuster throughout the claim.
Can hail damage a commercial flat roof without causing a leak?
Yes, and that is the most common scenario. Hail can fracture the reinforcing scrim inside a TPO or PVC membrane, bruise EPDM against the deck, or strip granules from modified bitumen without opening a hole. The roof keeps water out for another season or two and then fails. This is why damage is documented by system rather than by looking for active leaks.
Will our tenants have to close during commercial storm restoration?
In most cases, no. We develop a phased plan that sequences work by zone so unaffected areas of the building stay open. On multi tenant properties we coordinate directly with building management on scheduling, access and containment. Some structural damage does require closing a section, and if that applies we tell you at the assessment rather than mid project.
What is an IICRC Certified Firm and why does it matter for storm restoration?
The IICRC is the certifying body for the cleaning, inspection and restoration industry. A Certified Firm registers with the IICRC, employs technicians who hold IICRC certifications, and pledges to maintain awareness of the published standards for restoration work. Decor is IICRC Certified Firm number 70249741 with certified water damage and fire and smoke restoration technicians on staff.
