One drip over a wing or an avionics bay is a larger loss than the roof repair that stops it. In a hangar, the first question is what sits below the wet spot and whether it can be towed out before work starts. We trace the water to a panel lap, a fastener row, a door header or a gutter, and then mark the repair boundary so no crew member crosses the aircraft footprint. For a hangar near McKinney, TX, the roof schedule follows the flight schedule, and the work zone is cleared by the people who know what is parked inside.
A hangar roof spans a wide, open interior with few columns. The framing is long, the metal panels run in long sheets and the roof moves more with temperature than a short roof does. Movement works on fasteners and laps, and a panel that expanded in July can leave a gap by January. Many hangars use standing seam metal or exposed-fastener panels, though some carry a low-slope membrane over insulated deck.
We inspect the ridge, the eaves and the transition at the door wall, then the panel laps and fastener rows. In a membrane roof, we probe seams and check the drain bowls. Condensation is a frequent confusion in hangars: cold metal over warm moist air can drip on aircraft without any roof defect. We check for it before blaming the panels.
Skylights and light panels, where a hangar has them, add flashing to the list. Translucent panels yellow and crack under sun, and their end laps open first. We note each one, replace cracked panels and reseal the laps, so natural light stays and the leak does not.
A hangar's large door opening is its weakest line. The header carries a heavy load, the door tracks are exposed and the roof edge above them takes wind and rain together. Water that gets behind the header flashing runs down the door frame and into the interior, often on the side where aircraft are parked.
We check the header flashing, the end laps over the door and the gutters or drip edge above it. Wind pressure at the opening is high in a storm, so we also look at how the roof edge is fastened. An edge metal and gutter repair here is not cosmetic, because a lifted edge at the door wall can peel back a run of panels.
Seam failures along the door header are common after repeated wind loading. A seam failure repair re-locks the panel or replaces the clip, depending on the profile, and it is done before the next storm season.
Hangars hold fuel, solvents and oxygen, and hot work above them is the highest-risk step in the job. We avoid torch application and open flame wherever possible, choosing mechanical attachment, hot-air welding in approved zones or cold-applied adhesives. A hot work permit, a fire watch and a clear drawing of what lies below are all set before any heat source comes out.
The hangar manager tells us where fuel is stored, which tanks are in use and whether the fire suppression system will be impaired. Foam and sprinkler systems can be sensitive to heat and to cutting, so we mark their lines before any penetration is made. If a task cannot be done safely with aircraft or fuel inside, it waits until the space is cleared.
Grounding and static are a related concern. Metal panels, tools and cranes near fuel call for bonding, and we follow the hangar's rules on tools, cords and lighting inside the zone. Anything that could spark stays out of areas the manager has marked, and the crew lead walks the interior with the manager before and after each shift.
Debris is a safety problem around aircraft. A loose screw, a scrap of metal or a piece of membrane on a ramp can be drawn into an engine or damage a tire. We keep a tool count each day, sweep the work zone and the ramp below, and use magnetic sweepers on the pavement. Waste goes into closed containers, not open dumpsters.
Interior protection is cheap relative to the loss. Aircraft are towed out where possible, and where they stay, they are covered by the owner's approved protection and the roof zone above them is sealed first. The crew lead keeps a contact number for the hangar manager, so a rain delay or a loose item is reported in minutes.
Gutters and downspouts matter on a hangar because water falling at the door line lands where aircraft move. We check that they discharge away from the apron and the door tracks, and we clear any build-up of leaves and grit that blocks flow.
Springtime is when the National Weather Service sees the Metroplex's severe-weather peak, including large hail, damaging wind, flooding and tornadoes. A large metal roof gives hail a broad target, and wind loads on a hangar edge are substantial. A wind damage repair starts at the door wall and eaves, then runs panel by panel along the fastener lines. A drone roof inspection after a storm covers the surface without anyone stepping on the panels.
July afternoons normally reach 95.6°F and August afternoons 95.8°F, and a metal roof in July is hot enough to burn skin. We start at first light and stop before the peak, and we plan the repair for cooler hours so sealants cure properly.
Aviation properties are often secured, and entry can require badges, escorts and vehicle inspection. Cranes and lifts near an airfield may also need notice or approval based on height, so we raise it with the owner at the start. McKinney lists US 75, SH 121 and US 380 as its principal highway routes, and the city's location page puts Interstate 35 within about thirty minutes, which shapes how trucks reach a site, though the final approach is set by the property's gate and apron.
We confirm gate hours, escort rules and the lane that heavy trucks use before delivery. Trucks coming in from the US 75 and SH 121 district or from US 380 still wait at the gate, so the roof schedule allows for how soon the first truck can be cleared.
After the job, the closeout record lists panel and fastener work, door-wall flashing, drain checks and photographs. The same format fits a warehouse or a flex industrial building with a similar roof.
Share where water appears, what is parked below and the access rules at the gate. We will plan the inspection so the aircraft stay protected and the schedule holds.
Short answers to what owners and facility managers ask before a roof visit.
Not always. Aircraft are towed out when possible. If they stay, the roof over them is sealed first and the owner's protection is in place.
Cold metal over warm, moist air can condense and drip. We check for condensation before assuming a defect in the panels.
Only with a permit, a fire watch and a drawing of what is below. We prefer mechanical and hot-air methods and avoid open flame.
We count tools daily, sweep the pavement, use magnetic sweepers and keep waste in closed containers.
We mark its lines before any penetration and coordinate with the hangar manager so the system is protected or taken out of service by the owner.
