As an Elizabethtown industrial roofing contractor, we roof plants and large warehouses around process exhaust, heavy rooftop units, and long drainage runs.
Before an Elizabethtown industrial roofing contractor picks a sheet, the stacks and vents get checked, because the residue on the roof decides between these two.
PVC or another oil-resistant sheet for roofs that catch residue.
Fits plant roofs where exhaust leaves little or no residue.
Plant roofs carry loads and residue that office roofs never see, and these four conditions show up on most of them.
Oil and grease that settle on standard TPO or EPDM swell or soften the membrane around exhaust fans and process vents.
Heavy units on low curbs or steel frames, plus service carts, crush insulation that lacks a high-density cover board.
Water that travels far to an interior drain or scupper settles in low spots between outlets, especially around wide curbs.
Skylights and smoke vents spread across the field each need their own curb flashing, and old ones leak at the curb corners.
The membrane, insulation, and drainage plan are chosen together for a plant roof.
A full PVC roof where exhaust is widespread, or a separate membrane zone and sacrificial pads around one grease stack, with containment boxes at kitchen or process fans.
Compare with TPOCover boards rated for foot traffic and walkway pads routed to every service point protect the roof where plant staff work.
EPDM on plant roofsInterior drains with clamping rings and sumps, scuppers on the low side, gutters off open edges, and overflow outlets set above the primary drains.
Flat roof drainageOn a plant, the roof protects production as much as the building.
A sheet chosen from the maker's chemical chart holds up near the stacks that vent oil mist instead of softening around them.
Tapered insulation and outlets sized for long runs move rain off wide roofs before it ponds around curbs.
Sections are torn off and dried in one at a time, with protection over lines under any deck repair.
Walkway pads and curb caps keep maintenance traffic and dripping residue off the open membrane.
Unit shutdowns, crane days, and hot work rules are agreed with plant staff before the first section opens.
Photos and a marked roof plan show which zones carry special membrane and where each drain sits.
Call and tell us which stacks vent oil or grease, and the roof walk starts with your maintenance staff at those fans.
Plant roofs are planned around production, so the order of work starts with your staff.
We walk the roof with your maintenance staff to find which stacks run hot, which vent oil mist, and which sit idle, then cut cores and check the deck from inside.
The maker's chemical resistance chart for your process settles the sheet, and zones near grease exhaust get oil-resistant membrane or sacrificial pads.
Outlet types, tapered insulation, crickets, and overflow drains are drawn for that roof so water reaches an exit across long runs.
Unit and makeup air shutdowns, crane and lift days, fire watch and hot work rules, and crew routes away from forklift lanes are set with the plant.
Each area is torn off and dried in before the crew leaves, tied to the old roof with a temporary seal so overnight rain stays outside.
Walkway pads go to every service point, metal curb caps go on at fans, and you get photos and a marked roof plan.
Plant campuses usually mix roof types, and these two services cover the rest.
Office wings and cooled warehouse space on a plant campus often take welded white TPO over new insulation.
TPO roofing
Pitched steel buildings beside the plant take standing seam or R-panel roofs, installed or repaired with matching parts.
Commercial metal roofingAnswers about exhaust, drainage, and keeping a plant running during the work.
Size, load, and what comes up from inside. Industrial roofs cover more area, carry heavier units on curbs or steel frames, catch residue from stacks and vents, and see more maintenance traffic. That changes the membrane, calls for higher-density insulation or a rated cover board, and shapes how the crew works around the building.
PVC and other oil-resistant sheets hold up better near grease, oils, and chemical exhaust than standard EPDM or TPO, which can swell or soften. The maker's chemical resistance chart settles it for a given process, and one grease stack can get its own membrane zone and pads instead of a whole new roof type.
Usually both. Interior drains suit wide roofs where water sits far from any edge, scuppers suit parapets on the low side, and gutters suit open edges. Overflow drains or scuppers sit higher than the main inlet as a backup, and tapered insulation with crickets steers water to each outlet.
In most cases, yes. The roof is replaced in sections, each torn off and dried in before the crew leaves. Shutdowns of nearby units and intakes, protection over lines under deck repairs, crane days, hot work rules, and crew routes away from forklifts are planned with plant staff.
Because a nearly flat deck leaves water in low spots between drains, around curbs, and along walls. Tapered boards are cut with built-in slope and laid in a pattern drawn for that roof, with crickets and saddles. The added thickness raises the surface, so curb and threshold heights get checked first.
Yes. Each skylight and smoke vent sits on a curb that needs new flashing run high enough above the new roof, and older units that crack or leak at their curb corners are often replaced while the roof is open. The added insulation height is checked against every curb.
Start with a roof walk alongside your maintenance staff and a written plan for every stack, drain, and shutdown.
