Commercial roof replacement in Tulsa.
The roof is past its life. Repairs are piling up. Every storm season brings another round of calls from tenants and another invoice from a roofer who never finished the job right. A full replacement is not a cost, it is the end of that cycle.
Q: When does a commercial roof need full replacement vs. repair?
Tulsa commercial buildings take a beating. Summers push surface temperatures past 170 degrees on dark membrane roofs. Hail comes through three or four times a year. Winter cycles from 15 to 70 degrees in the same week. Most commercial roofing systems are rated for 20 years under ideal conditions. Oklahoma conditions are not ideal.
A commercial roof replacement is a capital project, not a maintenance call. It requires a contractor who can scope accurately, bid transparently, and execute on a building that has tenants, equipment, and operations running underneath. We have done this on office parks, retail strips, warehouses, churches, schools, and multi-family properties across the metro.
Every replacement starts with a documented inspection, core cuts to check insulation moisture, and an itemized bid you can hand to ownership or a board. We install TPO, EPDM, modified bitumen, standing seam metal, and built-up systems. The right one depends on your building and your budget.
Signs your building needs a new roof.
Roof past 15 years old
Most commercial membranes in Oklahoma hit end-of-life between 15 and 20 years. If yours is in that window and repairs are becoming regular, a replacement saves money over the next five years.
Repeated repair invoices
If you have spent on three or more repairs in the past two years without the leak staying fixed, you are putting money into a system that is failing systemically, not spot-failing.
Wet insulation on core cuts
Saturated insulation cannot be dried in place. It has to come out. When the core cuts show moisture throughout the field, the math almost always favors replacement over repeated patching.
Multiple active leak points
One leak is a repair. Three leaks in different locations mean the membrane is degrading across the field. The next storm will produce a fourth.
Visible membrane shrinkage
TPO and EPDM shrink as they age, pulling flashings away from walls and curbs. Once shrinkage is visible at the perimeter, the membrane has lost elasticity and cannot be restored.
Storm damage after hail
Hail punctures and bruising that covers more than 20 percent of the roof surface typically exceeds the threshold for repair. We document and photograph every impact for your insurance carrier.
Failed seams across the field
Adhesive-sealed EPDM seams fail in sections as they age. Heat-welded TPO seams can blister. When seam failures are distributed across the roof, a full replacement is the only complete fix.
Rising HVAC energy costs
A degraded or dark membrane absorbs heat and forces your rooftop units to work harder. A new reflective TPO or metal roof can cut cooling costs by 15 to 25 percent in Tulsa summers.
Five steps from first call to warranty packet.
Every replacement follows this sequence. You get a PM, a schedule, and weekly progress reports before we break ground.
Inspect and core-cut
We walk the entire roof, photograph every deficiency, and pull core samples to test insulation moisture content. You receive a written report with photos within 48 hours of the inspection.
Free / same weekSystem recommendation
Based on building type, budget, energy goals, and inspection findings, we recommend the right membrane system. We present two or three options with trade-offs laid out side by side. No pressure toward the most expensive option.
Data-basedItemized bid
Line-by-line bid covering tear-off, insulation, membrane, flashings, drains, and workmanship. Every number is visible. We sit down with your facility manager and walk through it before you sign anything.

NDL warrantyChoosing the right system for your building.
TPO is the most common choice for flat commercial roofs in Tulsa. It reflects UV radiation, welds at the seams, and carries a 20-year no-dollar-limit warranty. Best fit for offices, retail, multi-family, and any building where energy cost reduction matters.
EPDM is the budget-conscious option for warehouses and large-footprint buildings where cost-per-square-foot is the primary driver. Properly installed, it lasts 20 to 25 years with fewer complications than older adhesive systems.
Standing seam metal is the right call for buildings with a visible slope, high rooftop traffic, or long ownership horizons. Panels carry 40-year warranties and require almost no maintenance. The upfront cost is higher, but the 40-year math is hard to argue with.
Modified bitumen and built-up systems are the right fit when an existing BUR roof is being replaced in kind, when a property has rooftop equipment that requires a traffic-resistant surface, or when a two-ply reinforced system is specified by an architect or engineer. We install all of them.
What drives commercial replacement cost.
Four variables move the number more than anything else: square footage, insulation condition, number of layers to tear off, and the density of rooftop penetrations. A clean 20,000-square-foot warehouse with one dry insulation layer and four HVAC curbs is a very different project than a 20,000-square-foot office building with two membrane layers, wet insulation, a forest of pipe boots, and a parapet wall on all four sides.
The insulation question is often the biggest surprise in a commercial bid. Oklahoma energy code requires minimum R-values on commercial roofs. If your existing insulation is saturated, compressed, or undersized, replacement adds material cost that no one wants to see on line two of an estimate. Core cuts during the inspection remove that surprise before the contract is signed.
We do not post per-square-foot prices because they are misleading for commercial work. What we do provide is a fully itemized bid within 48 hours of the inspection, covering every line from material to labor to disposal. If you are managing the project for an owner or board, that document gives you everything you need to justify the capital expenditure.
The inspection is free. The estimate is itemized.
A replacement done wrong costs twice as much.
Commercial roof replacement is not the same job as a residential shingle swap. The systems are different, the inspections are different, and the consequences of a bad install are different. A seam that fails on a 40,000-square-foot warehouse does not just damage one room.
AE Roofing runs a dedicated commercial division. Our foremen hold flat-roof certifications from Carlisle, GAF, and Firestone. We carry OSHA 30 credentials on every commercial site. We have handled replacements on occupied retail centers, active warehouses, and school facilities where downtime is not an option and every phase has to be coordinated in advance.
Every commercial project gets a dedicated project manager. Weekly progress reports with photos. Material tracking. Inspection coordination. And after completion, an optional bi-annual maintenance plan that keeps the manufacturer warranty valid and catches problems before they become leaks.
