Scheduled annual and semi-annual commercial roof inspections across the Tulsa metro — zone-keyed photo logs, drain verification, parapet and flashing assessment, and capital-planning deliverables built for hail-belt buildings.
A documented inspection catches the $3,500 flashing separation before it becomes a $35,000 interior claim during a Tulsa spring storm. We walk, photograph, and report — zone-keyed to your building's roof plan, formatted for adjusters, asset managers, and capital budgets.
Commercial facility managers across the Tulsa metro typically learn about roof problems the same way: a ceiling stain appears, a tenant calls, or a section of acoustic tile comes down after a spring hail event tracking northeast out of the Wichita Mountains. By that point the water has usually been moving through the assembly for weeks — through a lifted flashing lap, a drain rim sealed shut with cottonwood debris, or a parapet cap joint that opened during the previous winter's freeze-thaw cycles. Annual inspections catch those precursor conditions before they migrate into the building.
We run inspections on scheduled routes across the Tulsa metro. Buildings in the BOK Tower corridor and the Brady Arts District are inspected on our downtown cycle. Buildings in the US-169 corridor and the South Elm industrial parks in Broken Arrow are inspected on our eastside route. The Woodland Hills and South Yale medical-office corridor runs on its own schedule with infection-control awareness at every healthcare-adjacent building. Each inspection produces the same deliverable regardless of building type: a zone-keyed photo log tied to a numbered roof diagram, a condition score per zone, and a three-column scope that separates what needs immediate attention from what to track and what to budget.
The report format matters as much as what we find. An inspection that produces only a narrative paragraph is useless for capital planning or insurance documentation. Our deliverable is structured so your CFO can read the scope column, your facility manager can hand it to an adjuster, and the next owner can build a reroof budget against it. That is the standard we hold ourselves to on every Tulsa building we walk.
Membrane condition: We photograph every field seam we can access, every lap joint, every area of membrane blistering, shrinkage, or granule displacement. TPO and EPDM shrinkage at parapet corners is a recurring finding on Tulsa commercial buildings from the 1990s — the membrane pulls back from the flashing termination and opens a water path before anyone notices. On modified bitumen roofs, we document granule loss and exposed base sheet areas that represent accelerated UV deterioration.
Drains: We pull every drain cover, check the clamping ring for corrosion and seating, verify the bowl is clear of debris, and confirm the drain leader is accepting flow. The Arkansas River valley receives higher annual rainfall than western Oklahoma, and Tulsa storm events routinely run at intensities above two inches per hour. A drain that is 30% blocked by sediment or cottonwood seed cannot keep up with those intensities — the roof fills and ponding stresses the membrane at seams and penetration laps. We documented the impact of the 2017 Tulsa County hail and debris event on drain function at multiple buildings in the South Elm industrial corridor, where partial blockage converted marginal drainage into active ponding claims.
Parapets and flashings: Every parapet cap joint, every reglet, every counterflashing lap, every pipe penetration boot, and every HVAC curb flashing on the roof plane. These are the highest-probability leak sources on any Tulsa flat-roof commercial building, and the items most consistently deferred because they do not look urgent until they fail during a storm event.
Equipment curbs and penetrations: Conduit penetrations, gas line penetrations, exhaust vent boots, and drain field penetrations. We photograph the flashing condition at each one and flag any showing sealant shrinkage, separation, or absent components. Penetration inventories on Tulsa commercial buildings grow over time as HVAC, electrical, and telecom trades add rooftop infrastructure — buildings from the 1990s routinely carry twice the penetration count of their original drawings.
Expansion joints: We verify the joint cover is seated and undamaged, that the expansion gap has not been packed with rigid caulk or spray foam — a common improper repair that causes tearing when Oklahoma's clay soils produce seasonal structural movement — and that termination flashings on both sides of the joint are intact and bonded.
Every inspection produces a numbered roof zone diagram — typically four to eight zones per building depending on roof complexity and footprint — with each zone assigned a condition grade, a summary of observed conditions, and a scope column with three rows: Immediate (address within 60 days), Monitor (re-evaluate at the next inspection visit), and Capital (budget within one to three years). Photos are keyed to zone numbers and item descriptions so there is no ambiguity about where a photograph was taken or what it shows.
We deliver the inspection report as a PDF within five business days of the roof walk. Clients on annual or semi-annual inspection contracts receive their reports on a consistent schedule tied to budget cycles — most clients want their pre-storm-season inspection in March and a post-summer inspection in September, bracketing Tulsa's primary hail window. Clients preparing for asset sale or refinancing receive the same report formatted to the documentation standard commercial lenders and buyers request for roof due diligence.
Adjusters, asset managers, and property owners have told us directly that the structured format is what they wish every contractor delivered. We built it because we were tired of explaining our own reports.
Annual inspections are appropriate for roofs under active manufacturer warranty and in documented good condition. Most warranty programs — Carlisle, Johns Manville, GAF — require annual inspections to keep warranty coverage active. We conduct and document each annual inspection in the format those manufacturers accept for warranty compliance, and we track the inspection schedule so the building owner does not accidentally lapse warranty coverage.
Semi-annual inspections are appropriate for roofs with known deferred maintenance, roofs in the final five years of a warranty term, buildings with a prior hail claim or active tenant leak complaints, and any building whose owner is preparing for sale. Tulsa's spring hail season (March through June) and the secondary storm window in September and October create two annual periods when storm damage can go undetected between annual visits — semi-annual scheduling with a pre-season walk and a post-storm-season walk closes that gap.
Roofs over occupied sensitive spaces — operating suites at Saint Francis or Hillcrest campuses, data center raised floors, occupied laboratory spaces in the Tulsa Research District near OSU-Tulsa — should be inspected semi-annually regardless of membrane age. The interior-use sensitivity justifies the more conservative inspection cycle, and we run inspection schedules for several such buildings in Midtown and South Tulsa where tenant operations make any interior water event unacceptable.
Yes. Our reports document observed conditions with dated, geotagged photographs and written condition descriptions. Adjusters at the major commercial carriers active in the Tulsa market regularly accept our inspection reports as supporting documentation. When we are conducting an inspection specifically to support a post-storm claim, we structure the report to address the adjuster's standard documentation requirements — including distinguishing pre-existing conditions from event-related damage, which is the key question in most commercial hail claims in Oklahoma.
We flag it in the Immediate scope column and call your facility contact the same day. For conditions presenting an active leak risk — an open flashing termination, a drain completely blocked before a forecasted storm event — we discuss emergency temporary repair at the time of the inspection so the building is not left exposed during the five-day report turnaround.
Yes. Most buildings on our inspection routes were installed by other contractors. We document what we find, not what we want to find, and we are not in the business of manufacturing scope to replace a competitor's work. Building owners who need an independent second opinion on another contractor's assessment are among our most common new inspection clients.
A 20,000 sq ft single-story commercial building with straightforward geometry and a normal penetration count takes roughly 90 minutes on the roof. A complex 100,000 sq ft building with multiple roof levels, heavy rooftop equipment, and a large penetration inventory takes a half day. We schedule accordingly and give your facility manager a time window before we arrive.
