Airport Terminal & Aviation Facility Roofing in West Virginia

Aviation roofing in Charleston runs on the airport's clock, not ours

An airport never has an off-season or an overnight when the building is empty, and that single fact reshapes every roofing decision before a sheet of membrane is ordered. West Virginia International Yeager Airport, CRW, is the state's primary commercial field serving Charleston and the Kanawha Valley, and it has a feature almost no other airport shares: it was built by shearing the tops off several ridgelines and filling the valleys between them, leaving the terminal and runway perched on an engineered mountaintop plateau above the city. That site drives hard rain runoff, exposes the buildings to ridge-top wind, and leaves no room for sloppy drainage. Every access point, material lift, and crew movement on a project here has to be cleared through the airport's facilities department, the FAA Part 139 safety program, and in places TSA security. We build that coordination into the scope at bid time instead of discovering it after the trucks arrive.

The campus is bigger than the terminal

Aviation roofing in Charleston is not just the passenger terminal. The same airfield supports cargo buildings, the rental-car center, fixed-base operator hangars, aircraft maintenance facilities, and support structures, and the region is fed by reliever and secondary fields as well.

• West Virginia International Yeager Airport (CRW)- the primary commercial airport on its mountaintop site serving Charleston and the Kanawha Valley
• Tri-State Airport (HTS)- the commercial field at Huntington serving the Tri-State region to the west
• Greenbrier Valley Airport (LWB)- general aviation with limited commercial service along the Greenbrier resort corridor

Security clearance does not disappear just because the work moves off the terminal and onto a cargo apron or a hangar row. Badging and escorted access apply across the whole campus, and our crews plan for that rather than running into a locked gate on the first morning.

Terminal roofs carry loads ordinary commercial roofs never see

The systems on a terminal go beyond a standard single-ply field. Airside roofs catch jet blast, which means the membrane adhesion or ballast has to be rated well past what a comparable warehouse would ever need. Terminal mechanical systems are denser and heavier than typical commercial, so the roof carries more curbed penetrations and more flashing maintenance points per acre. And terminals tend to be long, flat, lightly sloped expanses where drainage design is everything and the tolerance for standing water is essentially zero, a problem made worse by the volume of rain that comes off CRW's exposed plateau. We design these roofs around drainage and uplift first and the cosmetic membrane choice second.

High-bay hangars are their own structural problem

General aviation work shifts the challenge from security to structure. FBO and private hangars are tall, wide, clear-span buildings, frequently pre-engineered metal systems or wide-flange steel, and they generate serious wind uplift across that open span. The fastening pattern and seam geometry have to be matched to the building's real uplift and thermal-movement behavior, not borrowed from a low-rise commercial detail. On exposed reliever-field sites the wind exposure is often higher than at the shielded terminal, so the spec has to account for it. We install standing-seam metal and single-ply systems on these structures throughout the region and engineer the attachment to the building in front of us.

How we run a job on a live airfield

We develop a phased work plan with the facilities department and the Part 139 coordinator and get it approved by airport operations before mobilizing. Material deliveries, crane lifts, and anything near airside areas go into approved windows and, where required, into the FAA NOTAM process. Crew credentialing for airside authorization is confirmed before anyone steps onto a controlled apron, and we will not put an uncleared worker in a secure zone to save a day. Our pre-project survey documents every penetration, curb height, and mechanical clearance so the flashing for oversized equipment is engineered individually rather than improvised. For most terminal reroofs we specify a TPO, PVC, or KEE single-ply on tapered insulation to fix drainage and kill ponding; for new high-bay hangars we usually move to standing-seam metal. The final spec comes after we walk the roof with your facilities engineer, because an airport roof is not a building we want to learn on.

Airport & Aviation Roofing Questions

How do you handle scheduling at an operational airport like Yeager?

We build a phased work plan with the facilities department and the FAA Part 139 coordinator and get it approved by airport operations. Deliveries, crane lifts, and any airside work go into approved windows and into the FAA NOTAM process where required. This is a standard part of our project setup, not an exception.

What roof systems are standard for large-span terminal roofs?

Most terminal reroofing uses a TPO, PVC, or KEE single-ply on a tapered insulation system to improve drainage and address ponding. New high-bay aviation structures and hangars are often standing-seam metal. The choice depends on the existing deck, load capacity, and operational constraints, and we develop the spec after walking the roof with your facilities engineer.

How do you deal with the density of HVAC and mechanical penetrations on terminals?

Terminal mechanical density runs well above standard commercial. Our pre-project survey documents every penetration, curb height, and clearance before we build the work plan, and flashing for oversized curbs and complex through-penetrations is engineered individually rather than using standard low-rise details.

Can you work on airside structures near active runways and aprons?

Yes, with appropriate badging and full coordination with airfield operations. Airside work needs a higher level of pre-planning and crew credentialing, which we factor into the bid timeline. We do not mobilize crew without confirmed airside authorization.

Do you handle hangar roofing for FBOs and general aviation?

Yes. High-bay hangar roofing, from a single-bay private hangar to a multi-unit FBO complex, is a regular part of our work. These wide clear-span steel and pre-engineered buildings have specific uplift and thermal-movement behavior, and we engineer the fastening and seam geometry to the actual structure.
