Fan Bases
Exhaust fans shake their bases loose and drop residue around them. The sealant at the base dries, and water slips under the fan.

As an East Chicago commercial roof repair contractor, we repair flashing and membrane around the fans, stacks, and curbs on busy industrial roofs.

East Chicago commercial roof repair centers on the equipment. On plant roofs here, most leaks start at a curb, a stack, or a fan.
Residue from exhaust lands on the membrane around each unit and softens it over time. We clean the repair area down to firm material first, because patches and sealant only hold on a clean surface.
Plant roofs here carry more equipment per square foot than most. These five details fail first.
Exhaust fans shake their bases loose and drop residue around them. The sealant at the base dries, and water slips under the fan.
Hot stacks expand and contract with every cycle. Their collars and storm caps crack, and water runs down the outside of the pipe.
Rooftop units sit on curbs with four corners of flashing. Vibration splits those corners, often on the side facing the wind.
Dust and process residue pack drain strainers tight. Water backs up and ponds around the units nearest the drain.
Crews servicing equipment walk the same lines across the roof. Without pads, those routes wear thin and puncture.
Equipment-heavy roofs improve one unit at a time. These are the changes around each one we repair.
Industrial roofs here still call for all four repair types. Each pair shows where one applies.

Between the units, East Chicago plant roofs are mostly low-slope membrane. Drains and seams in that field get flat roof repairs.

Warehouse and shop bays beside the plants often have metal roofs. Screw rows and laps there get resealed and replaced by the run.

On roofs this crowded, water can enter at one curb and drip near another. A trace from the floor up sorts out which unit is the source.

Fans, stacks, and curbs are where East Chicago roofs fail most. Industrial repairs rebuild that flashing with materials that stand up to residue.

(219) 389-4915Call UsEquipment roofs need the plant staff involved before any work. These steps keep the repair and the line both running.
Your maintenance staff tell us which units run hot, which ones exhaust residue, and which can be shut down briefly for the repair.
Residue and softened membrane are removed around each unit until the surface is clean and firm enough to hold a patch.
Curb corners, fan bases, and stack collars get new flashing, and residue-resistant material goes where exhaust lands.
A unit-by-unit photo list shows what was repaired and what to watch, so maintenance can check it on their rounds.

Each row shows the short answer. Open it for the rest.
We repair leaks on industrial and commercial roofs across East Chicago. Fans, stacks, and heavy equipment wear the membrane and flashing around them, so we trace each leak to its detail, clean residue off the repair area, and repair it on firm material.
Plant schedules set the repair order. Noisy or dusty steps go between shifts, units are shut down only when your staff agrees, and equipment below an opened deck gets covered.
Send the building address and which unit or bay is leaking. We repair plant, warehouse, and shop roofs in East Chicago and start each visit at the drip inside.
Look for a roofer who repairs industrial systems, carries insurance, and asks about your equipment and safety rules before the visit. Expect photos of each repaired unit and a written note of what still needs watching.
Grease and chemical residue from exhaust sit on the membrane and break it down over time, and sealant at the fan base dries out faster around it. Cutting back to firm material and adding a residue-resistant layer slows the next round of damage.
Tell us which units sit over the leaks and when your shifts run. We walk the roof with your maintenance lead and price the repair.
