Shaking Fan Curbs
Exhaust fans run around the clock, and their curb flashing tears at the corners. Rain then runs inside the curb and drips onto whatever sits below.

As a Mooresville commercial roof repair contractor, we fix plant and warehouse roofs on schedules set with your safety and maintenance staff.
Mooresville commercial roof repair on plants follows the safety plan already in place for that building.

Plants in Morgan County carry exhaust fans, stacks, and process equipment on their roofs. Repairs around them need hot work permits, lockouts, and access times set by plant staff.
We plan each job with your safety team, protect the floor below any opened deck, and patch temporarily over active lines until a window opens. Warehouses beside the plants get the same planning, set around their shipping hours instead of production.
Four plant roof conditions start most of our Mooresville work.
Exhaust fans run around the clock, and their curb flashing tears at the corners. Rain then runs inside the curb and drips onto whatever sits below.
Process exhaust leaves film that softens membrane and rusts nearby steel. The damage spreads in a ring around each stack on the roof.
Plant dust settles in drains and holds water on the roof. Standing water then finds any open lap or puncture near the drain.
Old leaks rust the steel deck until it flexes under foot traffic. A soft spot near equipment is often the first sign.
Maintenance staff cross the roof to fans and filters every week. Their paths wear through the membrane between the hatch and the equipment.
Process piping and electrical conduit pass through the roof in tight groups. Standard boots leave gaps between them that rain finds.
Plant repairs are planned so production keeps running.
Torn flashing is replaced with membrane that wraps the curb on all four sides and seals under a counterflashing at the top.
Rusted deck is cut out and replaced with new steel fastened to the joists, with containment set up below before the deck is opened.
Drains get cleared, new strainers, new clamp rings, and fresh membrane at the bowl so water leaves the roof again.
Tight groups of pipes and conduits get a sealed pan or custom flashing that closes the gaps between them.
Each row ties a plant roof failure to the repair that closes it.
Water drips onto equipment under the fan.
New wraparound flashing seals the curb on all four sides.
Rusted deck sags and ponds water over the floor.
Rusted sections are replaced and tied back into the roof.
Dust-packed drains back water across the roof.
Drains are cleared, rebuilt, and their scuppers reopened.
Weekly traffic wears membrane thin between the hatch and the fans.
Paths are patched and covered with walkway pads that take the wear.
Call with the line and its schedule. We will plan a temporary patch that holds until a repair window.
Plant jobs run on the plant schedule.


We sit down with plant safety staff to review hot work permits, lockout steps, access hours, and the lines running under each roof area.
Fans, stacks, curbs, drains, and deck get checked from end to end, with moisture readings across the field and photos of each defect.
Active leaks over running lines get a temporary patch that keeps water off the equipment until planned downtime arrives.
Permanent repairs are booked for planned downtime or a slow shift, with materials staged ahead so the window is used fully.
Curbs, deck, and drains are repaired from above, with containment set up below any opening in the deck.

Yes, including seams, flashing, drains, and the areas around fans and process equipment. Work follows plant safety rules, and the floor below is protected during repairs.
Choose one that plans with your safety staff, works under hot work permits, and repairs each roof system in its own material.
Curb count, wet insulation, deck damage, and how much protection the floor below needs. Repairs timed to downtime can add planning but avoid lost production.
Warehouses and offices get the same tracing and matching-material repairs, with scheduling set around shipping or office hours.
A well-placed temporary patch keeps water off the line for weeks while the permanent repair is planned. We check it after each heavy rain and reseal it if the edges start to lift, so the line stays dry until the shutdown window.
Plant rules apply to every crew member on the roof. Fans and equipment near the repair are locked out by your staff before we touch their curbs.
Shutdowns are the best window for work over active lines. We plan materials and crew size ahead so the repair fits inside the shutdown hours, and we review the finished work with maintenance before the lines restart.
A pitch pan is a small sealed box around pipes or conduits that pass through the roof together. It closes the gaps between them that individual boots cannot, and it gets checked each spring because the sealant inside shrinks over time.
Call with the plant address and the area that leaks, and we will plan around your shifts.
