As a Louisville commercial roof repair contractor, we trace leaks and repair flat, metal, and industrial roofs on business buildings across Jefferson and Bullitt counties.
Your Louisville commercial roof repair contractor handles four kinds of repair work. Each card lists what gets checked on the roof and what gets fixed.
Flat roof leaks start at seams, curb flashing, and drains far more often than out in the open field of a TPO, EPDM, modified bitumen, or built-up roof.
Exposed-fastener and standing seam roofs leak where daily panel movement works screws loose, end laps open, and rust settles at gutters and low panel ends.
Ceiling stains rarely sit right under the hole, so leak work starts at the drip inside and follows the water uphill to the seam, curb, or penetration feeding it.
Plant and warehouse roofs get repaired around production, with hot work permits, fall protection at skylights, and every opening sealed before the crew leaves.
Most repair calls begin with something seen from the parking lot, at a desk, or on a roof walk. Here is what each sign points to.
Water spilling over the front of a gutter in steady rain points to a clogged outlet or an undersized downspout.
A bent strip of edge metal at a corner gives wind a handle to peel back the perimeter membrane.
Orange runs below a metal roof line trace back to rusted gutters, failed washers, or corroded panel ends.
Because water travels along deck flutes and wet insulation, the stain often sits several feet from the opening.
Leaks that show up only with sideways rain come through parapet coping, counterflashing, or ridge closures.
Steel deck rust seen from inside in several bays signals wet insulation spreading under the membrane.
Dirt rings left after water dries mark a low area around a drain that sits high or keeps clogging.
Lift a lap with a finger and it has lost adhesion, letting water run under the membrane.
Screws standing proud of a metal panel have worn washers that leak a little more with each rain.
A repair keeps the existing roof in service by fixing the details that let water in. These are the gains owners notice afterward.
Fixing the true entry point stops the drip over inventory, equipment, and offices, so nobody has to move a bucket each time it rains.
Catching a leak early keeps water out of the insulation boards, which wick it outward and turn a small repair into a section replacement.
Rebuilt curb flashing and a cricket on the uphill side move water around rooftop units, the busiest spots on most commercial roofs.
Clearing strainers and resetting a drain that sits high shortens the time water stands on the membrane after each Louisville storm.
Refastened edge metal and coping caps leave wind nothing to grab along the perimeter, where peeling damage tends to start.
Move stock out from under the drip, set buckets, and note the time and wind direction. Then call us to line up a repair.

Schedule Free InspectionMoisture readings and cores decide which column a roof belongs in, and one building can need repair on one section and replacement on another.
Every visit follows the same order, from the first roof walk to the notes you keep for next time.
We walk the roof and the interior leak areas, then check every seam, curb, drain, and fastener row upslope of each stain. Notes on when the drip appears point us to the right side of the building.
Moisture meters, an infrared scan at dusk, and water run on one detail at a time separate the real source from spots that only look suspect. Testing one curb or lap at a time keeps the answer clear.
Ladder or hatch access, fall protection near skylights, and a hoist for material get set before any membrane is opened, with walk paths kept clear of tenants and deliveries.
Damaged material is cut back to solid membrane or metal, cleaned, primed, and covered with a matching patch, flashing, or panel section. Each opening is sealed before the crew leaves for the day.
You get photos of the repaired seams and flashing, the conditions to watch next, and any section that is heading toward restoration or replacement, ready for your maintenance file.
Is your building near Louisville? We repair commercial roofs in the towns below; for anywhere else, call us or send us a message.
Shopping center and office roofs where a curb leak can pull in an HVAC tech, a sheet metal shop, and an electrician.
Plant roofs that switch from built-up to metal to single-ply at each addition, each transition a likely leak.
Storm leaks get a logged temporary patch, and larger section repairs wait on the City Clerk registration.
Commercial buildings along Preston Highway carrying decades of sign brackets, dish mounts, and conduit through the roof.
Warehouse roofs with long exposed fastener rows, yellowed skylight panels, and gutters that empty onto truck courts.
Buildings along Dixie Highway where high winds lift edge metal, shift coping caps, and tear gutter straps loose.
Office and retail roofs approved through the city permit desk, with some parcels on the Oldham County side.
Low sites near the Salt River, where gutters and downspouts need to carry roof water well clear of footings.
Older Bullitt County metal buildings coated in roofing cement that comes off before any new sealant goes on.
Short answers to what owners ask most before a repair visit.
Commercial roof repair fixes the exact places water gets in, such as open seams, punctures, failed flashing, clogged drains, and loose fasteners. On Louisville buildings the common calls are lifted seams, punctures near HVAC units, flashing pulled off parapets, and backed-out screws on metal panels. The aim is a dry building with the existing roof kept in service.
Look for soft, bruised spots on modified bitumen or built-up roofs, dents with cracked paint on metal panels, cracked skylight panels, split vent caps, and granules washed into gutters. Hail damage often stays hidden until the next rain finds it. Take photos soon after the storm, and walk the roof only when it is dry and safe.
Access, tracing time, and the amount of damaged material drive the price most. A tall building that needs a lift costs more to reach than a one-story shop, and leaks spread across several sections take longer to trace. Wet insulation removal, extra curbs and drains, and after-hours work add to it.
The National Weather Service office in Louisville posts warnings and storm reports for Jefferson County, and adjusters usually ask for the storm date and type. Keep those records with photos of damaged edge metal, coping, or panels, interior photos of new leaks, and notes on hail size or wind. File the repair invoices in the same folder.
Repairs leave drains and downspouts discharging where they already do. Moving an outlet changes where stormwater lands on the property, so any move gets cleared first with the Metropolitan Sewer District, which runs sewer and stormwater service across Louisville Metro. Rusted gutter outlets, cracked drain leaders, and debris-choked scuppers get repaired in place.
Yes, as a temporary fix. Wet-surface mastic, peel-and-stick tape, or a weighted tarp over a damaged section slows the water until the roof dries. Each temporary patch gets logged with its spot and date, and the permanent repair follows in workable weather with material matched to the seam, drain, or flashing.
