An Airport Roof Doesn't Follow a Standard Commercial Timeline
Aviation roofing starts from a fact that governs everything else: the facility runs around the clock and cannot stop for a roofer. Wilmington Airport (ILG) in New Castle is Delaware's primary general-aviation and limited-commercial airport, and it is also a working UPS air-cargo gateway, so freight and aircraft move on it day and night. Every access point, material lift, and crew deployment has to be coordinated with the airport's facilities department and its FAA Part 139 safety program, and in some areas with TSA security protocols. We build that coordination into the scope before the contract is signed, not after the crew shows up. The same discipline carries to the aviation-support and logistics buildings clustered around ILG and out along the I-95 and US-13 corridors that feed it.
What Keeps Aviation Roofing in Demand Here
ILG's UPS cargo operation and Wilmington's position in the freight network running up I-95 toward Philadelphia International keep a steady base of aviation-related buildings in service - cargo facilities, hangars, maintenance shops, and the logistics structures that support them across New Castle County. These are large-footprint, low-slope buildings that take a lot of weather and a lot of mechanical load, and they cannot afford downtime, which is exactly why their roofs need to be specified and sequenced by someone who understands how an airport campus operates.
Airports Are Served by a Wider Regional Network
- Philadelphia International Airport (PHL) - major hub roughly 30 miles north up I-95
- Baltimore/Washington International (BWI) - large hub to the south
Big Low-Slope Roofs With Almost No Slope to Spare
Terminal and aviation roofs tend to be long, flat expanses with minimal pitch, which makes drainage design the whole game - ponding tolerance is close to zero, and a low spot that would be a nuisance on a small roof becomes standing water and a leak risk over a terminal or cargo floor. We pair that with a tapered insulation layout that builds slope back into the assembly and moves water to the drains. The large surface area also means thermal movement and edge detailing matter more, since there is simply more membrane expanding and contracting through Wilmington's seasonal swings.
Wind and Jet Blast Push the Spec Higher
Airside roofs take wind uplift on an exposed field plus jet-blast and prop-wash forces that a comparable warehouse never sees. That calls for membrane adhesion and ballast or attachment specifications beyond a standard logistics building, and edge metal detailed to stay put under repeated gusting. High-bay hangars add their own challenge: wide clear-span roofs over open bays generate large uplift loads, so the fastening pattern and seam geometry have to be designed to the actual structure rather than loaned from a smaller building.
Dense, Heavy Mechanical Equipment
HVAC on a terminal is denser and heavier than ordinary commercial, which means more curbed penetrations and more flashing touchpoints to maintain. Each oversized equipment curb and complex through-penetration is detailed individually - generic patterns do not belong on an aviation roof. Our pre-project survey documents every penetration, curb height, and mechanical clearance before we write the work plan, so the flashing scope is built for what is actually up there.
Working on a Live Campus, From Terminal to Hangar
Aviation-adjacent buildings - cargo facilities, FBO hangars, aircraft maintenance shops, rental-car centers, and on-campus hotels - each carry their own demands, but the airport coordination requirement never goes away. Badging and security access are planned for, not discovered onsite, and we do not mobilize crew to any airside area without confirmed authorization. Material deliveries, crane lifts, and any work near active aprons or taxiways are scheduled into windows approved by airport operations and coordinated through the FAA process where it applies. For terminal re-roofing we typically specify a TPO or PVC single-ply membrane over tapered insulation to fix drainage and ponding; for new high-bay hangars and aviation structures, standing-seam metal is often the right call. The system is chosen after walking the roof with the facility's engineer, against the existing deck, its load capacity, and the operational constraints of a 24/7 site.
Airport & Aviation Roofing Questions
We develop a phased work plan with the airport facilities department and the FAA Part 139 coordinator and get it approved by airport operations. Material deliveries, crane lifts, and any work near airside areas run in approved windows and are coordinated through the FAA process where required. On a 24/7 cargo airport this is a standard part of project setup, not an exception.
Most terminal re-roofing in Wilmington uses a TPO or PVC single-ply membrane on a tapered insulation system that improves drainage and addresses ponding. New high-bay aviation structures and hangars are often specified in standing-seam metal. The choice depends on the existing deck, load capacity, and operational constraints, decided after walking the roof with your facilities engineer.
Terminal HVAC density is much higher than standard commercial. Our pre-project survey documents every penetration, curb height, and mechanical clearance before the work plan is written, and flashing for oversized curbs and complex through-penetrations is engineered individually rather than using generic patterns.
Yes, with proper badging and full coordination with airfield operations. Airside work takes 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 - it is a baseline requirement we enforce.
Yes. Hangar roofing - from a single-bay private hangar to a multi-unit cargo or FBO complex - is a regular part of our aviation work around ILG. High-bay hangars with wide-flange steel or pre-engineered systems need a roofing approach matched to their uplift and thermal-movement behavior, and we design the fastening and seam detailing to the structure.
