If Your Roof
Is Gummy or Cracked Around an Exhaust Fan
That membrane gets cut out and replaced with a grease-resistant sheet, with a containment box under the fan.

Which Plant Roof Sections Take a Repair?
Large roofs fail in sections. A Lexington industrial roof repair contractor sorts which sections need a patch and which need a survey.
If Your Roof
Shows Stains in a Line Under an Expansion Joint
Split bellows or covers get replaced and the joint flashing resealed so the joint still moves.
Start WithExpansion Joint Repair
If Your Roof
Has Soft Spots on the Path to Rooftop Units
Crushed insulation gets cut out and replaced, then walkway pads go down along that path.

If Your Roof
Leaks in Several Bays After Years of Patches
A moisture survey marks every wet area on a roof plan before more patches go on.

Plant Roof Damage Seen From the Floor and the Roof
On a plant roof, the floor below often shows trouble before anyone walks up top.
Residue Around a Fan
Inside The Building
Drips show up near process equipment under a grease or vent exhaust.
On The Roof
Swollen EPDM or brittle TPO sits in the discharge path of the fan.
Line Stain at a Joint
Inside The Building
A straight stain runs across the ceiling along the building's length.
On The Roof
Expansion joint bellows have torn, and membrane at the joint ends is stretched tight.
Soft Spots on Service Paths
Inside The Building
Leaks gather in the bay under the path from the roof hatch to the units.
On The Roof
Cover board has crushed underfoot, and the membrane has scuffed or punctured.
Long Seam Opening in Sections
Inside The Building
Wet spots appear in a row across several bays over time.
On The Roof
Shrinkage and movement have opened a long seam run in separate stretches.
Industrial Roof Repair Options for Lexington Plants
Four repair types cover most plant and warehouse roof calls.
Roof Damage From Exhaust Fans and Grease
Damaged membrane at the discharge point gets replaced with a grease-resistant sheet such as PVC, a sacrificial pad or containment box goes under the fan, and stacks get extended where heat is the cause.
Expansion Joint Repair on Large Roofs
Split bellows and covers are replaced and the joint flashing resealed, following the joint maker's detail where one exists, so the joint keeps moving as the building heats and cools.
Walkway Pads Around Rooftop Equipment
Scuffed membrane gets patched, crushed boards get replaced, and pads get heat-welded or adhered along the paths service techs walk to each unit.
Moisture Survey Before Roof Repairs
Infrared scans at night, capacitance or impedance readings on a grid, and core cuts mark wet areas on a roof plan so repairs replace only what is wet.
Production Keeps Running
Smaller leak fixes happen during shifts once the area underneath is cleared or covered, and larger repairs wait for a shutdown or weekend window. Lines stay protected while the work goes on overhead.

- Hot work permits in place
Benefits of Repairing Your Roof
Plant roof repairs are about keeping production running under a dry roof.
Wet Areas Only
A survey-based plan cuts out the wet sections and leaves dry roof in place.
Fewer Repeat Fan Leaks
Grease-resistant sheets and containment boxes slow the breakdown that keeps returning around exhausts.
Safer Service Routes
Walkway pads mark the path and spread foot loads across the membrane near rooftop units.
Grease Pooling Around the Exhaust Fan?
Grease softens membrane until it splits. Call us to plan a repair around your next shutdown window.
Call UsWorking With a Lexington Industrial Roof Repair Contractor
Plant repairs follow your safety rules from the first walk to the last photo.
- WALK
Inspect Your Roof
We walk the roof with your maintenance lead, note every fan, vent, joint, and service path, and confirm access from the hatch or ladder.
- PERMIT
Set the Safety Plan
Lockouts for nearby exhaust fans, hot work permits for heat welding, and covers for lines below get agreed before the crew goes up.
- SURVEY
Survey Where Needed
Roofs with leaks in several places get an infrared or meter survey, so the plan cuts out only the wet sections.
- REPAIR
Repair by Section
Damaged membrane, joints, and boards get replaced section by section during shifts or the shutdown window.
- PHOTO
Hand Over the Record
Your maintenance file gets photos, the marked roof plan, and notes on areas to watch.
Repairs We Pair With Plant Roof Work
Plant campuses mix roof types, so these often come up on the same visit.
Flat Roof Repair
Office wings and low-slope additions get seam, blister, and drain repairs matched to their membrane.
Typical Repairs
- Seams welded or taped to match
- Drain bowls reset
- Blisters cut and patched
Commercial Metal Roof Repair
Metal warehouses and storage buildings on the same campus get fastener, lap, and panel repairs.
Typical Repairs
- Corroded fasteners swapped
- End laps sealed and taped
- Rusted gutter sections replaced
Commercial Roof Leak Repair
Hard-to-find drips over equipment get traced with hose tests and infrared before anything is cut.
Typical Repairs
- Drip mapped to roof landmarks
- Hose tests from low to high
- Temporary seals in wet weather
Industrial Roof Repair Questions for Lexington Facilities
Scheduling, exhaust damage, joints, foot traffic, and surveys.
How Is Roof Repair Scheduled Around Plant Operations?
Your maintenance and safety staff set the access times, hot work rules, and which areas can have crews overhead. The plan covers lockout of nearby fans, hot work permits, protection for lines below, and access routes that avoid process piping.
Shutdowns and weekends suit larger repairs, and smaller leak fixes happen during shifts once the area below is cleared or covered.
How Do Grease and Heat From Exhaust Fans Break Down an Industrial Roof?
Grease, chemical residue, and hot discharge soften or crack membrane around the fan. Expect swollen or gummy EPDM near grease exhaust, brittle TPO where hot air blows across it, and corroded panels near acidic discharge.
Repairs use a grease-resistant sheet such as PVC, a sacrificial pad or containment box, and longer stacks where heat is the cause. The plant's safety data sheets help confirm which materials hold up.
How Are Expansion Joints and Long Seams Repaired on Large Roofs?
Split bellows or covers get replaced, the joint flashing gets resealed, and the joint is checked to confirm it still moves as the building heats and cools. Torn bellows, stains in a line under the joint, and membrane stretched tight at the ends are the signs.
Long seam runs get probed end to end, since shrinkage opens them in sections.
How Is Foot Traffic Damage Repaired Around Rooftop Equipment?
Scuffed or punctured membrane gets patched, crushed insulation gets replaced, and walkway pads go down along the service paths. Damage gathers between the hatch and the units, where panels and tools get set down, and wherever cover board has crushed.
Heat-welded or adhered pads spread foot loads and mark the path. Crushed boards come out before the patch goes on.
When Does an Industrial Roof Need a Moisture Survey Before Repairs?
Order one when leaks show up in several places, when the roof carries many past patches, or when soft spots spread past one detail. Infrared scans show warm wet areas at night, meters give readings on a grid, and core cuts show each layer.
The survey marks wet areas on a roof plan, so repairs replace exactly what is wet and each section gets the right call.
