Airport Terminal & Aviation Facility Roofing in Milwaukee, WI

Roofing for terminals, hangars, and aviation support buildings around Milwaukee — huge roof areas, wind and jet blast, and operations that never stop.

An airport never closes, so the roof job has to plan around that

The thing that separates aviation roofing from every other commercial project is that the building does not stop. Milwaukee Mitchell International Airport runs around the clock, with American, Delta, Southwest, and United moving passengers through at every hour, and that means there is no night where the terminal goes dark and a crew has the place to itself. Every access point, every material hoist, every crew movement has to be worked out in advance with the airport's facilities team, the FAA Part 139 safety program that governs operations there, and TSA security protocols in the secured zones. We treat that coordination as the first part of the scope, settled before the contract is signed rather than discovered on the first morning of mobilization.

Milwaukee sits right on Lake Michigan, and that location does two things to an airport roof. It drives a maritime freeze-thaw cycle and wind-driven rain that the membrane and edge details have to be specified for, and it generates the kind of hard, sustained wind that makes uplift the governing design factor on these wide, exposed roofs.

Terminal roofs are huge, flat, and intolerant of standing water

Terminal roofs cover enormous, nearly flat expanses with very little slope to work with, which makes drainage the make-or-break detail. There is almost no tolerance for ponding on a roof this size — water that sits finds the one weak seam and the one undersized drain. Most terminal re-roofing here runs a TPO or PVC single-ply over a tapered insulation system specifically to build slope back into a deck that never had enough, and we size the drains and overflow scuppers for the real rainfall and snowmelt loads a Wisconsin year delivers.

Terminals also carry far heavier and denser mechanical equipment than a comparable commercial building. The HVAC serving a concourse means a crowded field of large, curbed penetrations, each one engineered individually rather than dropped onto a standard detail. On the airside, roofs near gates and aprons take jet-blast exposure, which demands adhesion and ballast specifications well beyond what we would put on a logistics box of the same footprint. We survey every curb, clearance, and penetration before building the work plan.

Beyond the terminal: hangars, cargo, and the relievers

A lot of aviation roofing around Milwaukee is not the terminal at all. It is the cargo facilities, the rental-car centers, the FBO buildings, the aircraft-maintenance hangars, and the hotels sitting on the airport campus — and the area's general-aviation relievers carry their own steady demand:
