Commercial Roofing at Rochester International Airport, Rochester, MN

A flashing joint at a rooftop penetration can be harder to inspect than a broad membrane field because nearby equipment and operating routes restrict the approach. Airport records describe a cargo ramp exceeding 330,000 usable square feet, while FedEx is the cargo operator with an Air Commerce Drive office. Neither detail supplies a roof takeoff: pavement and building-envelope measurements are different quantities. We identify the airport structure, roof zone and site representative before preparing a roofing scope.

The airport also hosts the Airport Business Park for developers and investors. Those are separate planning and operating contexts within the airport campus, so a roof report should identify the exact building rather than assign one condition to the entire area. A visit at Airport Business Park or the RST Cargo Facility receives its own inspection boundary, photographs and work sequence.

We begin with the address or facility name, reported symptom and available roof plan. On the roof, the walk follows seams, curbs, vents, drains and metal transitions around the affected area. A leak near an equipment curb may travel along insulation before appearing inside, so we compare roof elevation and interior evidence rather than assigning the source from the ceiling mark. A commercial inspection records the visible path, tested areas and any section the crew could not reach.

Airport operations make the property contact and site access plan essential to scheduling. We confirm roof entry, escort requirements, material route, lift placement, delivery windows and areas that must remain clear. If a locked zone or operating restriction limits the visit, it stays in the report as an access condition. We can stage a return after authorization rather than leave a roof section described as inspected when it was not available for review. For properties with more than one operating contact, we confirm who can approve access and repair direction for each building. Photos carry a facility and roof-section label before they enter the closeout record, keeping a cargo-area observation from being applied to another airport structure.

Cargo ramp area and roof area are separate measurements; roof dimensions come from drawings or field measurement at the building. We identify the assembly from records, membrane markings, attachment details and suitable field tests, then map each repair area to its roof section. A condition report can preserve those measurements and photographs for facilities staff without confusing pavement, floor area and roof area.

At the actual defect, we inspect the field sheet, seam lap, flashing termination and substrate for compatibility before selecting a repair. A membrane opening may take a heat-welded patch; a curb transition may need new flashing up the sidewall and secure termination at the top. TPO system repair follows different preparation than EPDM, so we verify material and test an appropriate area when needed. Corroded metal or a blocked drain is scoped separately from membrane work.

A puncture or failed flashing detail can remain a local repair if the nearby membrane and insulation are sound. Repeated leaks, widespread moisture or loose perimeter attachment may justify testing and a comparison of repair, recovery and replacement. We list measured dimensions, known materials, access assumptions and unresolved conditions. An impact review should be based on observed marks and roof evidence, with damage documentation kept separate from any insurance decision.

FedEx's airport office on Air Commerce Drive and the cargo-ramp report can help a facilities contact identify the operating context, but they do not establish which roof requires work. The roof record should name its own asset and date. A roof asset register can track those details across airport properties while preserving separate histories for Rochester Technology Campus or other Rochester sites. The recommendation remains tied to the area inspected.

We return dated roof-zone photos, confirmed material where known, repairs completed and items awaiting testing or approval. The record notes access restrictions and any area left uninspected. If a temporary tie-in remains, the closeout identifies its location and the permanent detail still needed. Facilities staff can then match the roof action to the work order, building contact and follow-up date rather than relying on a site-wide note.

Send the airport facility name or address, roof concern, available drawings and the person coordinating access. We will define the work area and return a measured repair or testing scope. A leak can be addressed at night, over a weekend or during a holiday, with the temporary and permanent steps recorded separately. If the leak requires immediate protection, we record that work separately from permanent correction and state what needs authorization before the next visit.
