Commercial Roofing in Progress Park, Sherman, TX

Process heat moves up. Steam, cooking vapor and furnace exhaust rise through a plant ceiling and meet the roof deck. Over years they soak insulation and cook membranes. Progress Park in Sherman, TX is a master-planned industrial park of roughly 3,300 acres, assembled by the Sherman Economic Development Corporation since the 1990s. Its tenants include Tyson Foods, Sunny Delight Beverage, Kaiser Aluminum and Panda Energy, and the park has direct access to the BNSF Railway.

Industrial roofs of this kind are working surfaces. They carry stacks, fans, curbs and pipe racks, and they are exposed to what the plant makes. We read each one for that load before we price anything.

Food and beverage plants run wet. Washdown water, cooking steam and cold storage all change what air does at the ceiling. Warm, damp air rises, meets a cold deck and condenses. The insulation under the membrane takes on water without any hole above it.

Metals plants run hot. Heat and dry exhaust age the membrane near vents, and radiant heat can soften sealants at curbs. Powder and dust settle on seams and hold moisture against them.

Both kinds of building need the same first step. We scan the roof for moisture, mark the wet zones and cut cores at the edges. The cores tell us how much of the assembly is wet and whether the deck is still sound. Our manufacturing plant roof work starts there, and so does every visit here.

Rail adds a small factor. Heavy trains passing a rail-served site send low vibration through the ground and the structure. Fasteners that were tight on day one can back out slowly. We check deck attachment along the roof edge and near heavy curbs, and we log any loose fasteners by grid line.

Exhaust points are the first to fail. Warm, chemical-laden discharge lands on the membrane near the opening and breaks it down. The sheet chalks, blisters or thins. A fan curb that was flashed well on day one can open at the corners after years of vibration and heat.

We examine the membrane in a ring around each exhaust. We check curb corners, counterflashing, fasteners and the gasket under each unit. Where chemical contact is likely, we look at sheet types that resist it. Welded PVC is a common answer for fat and oil exposure, though the final choice depends on what the exhaust carries.

Walk paths matter in a plant. Maintenance crews cross the roof to reach units. A bare membrane under their boots wears out fast. Walkway pads cost little and protect the sheet.

The development corporation still owned about 550 acres of the park and put 64 acres under contract in 2017, so new industrial buildings keep arriving. A new roof is not a finished roof. Trades walk it for months, carrying tools and equipment, and punctures and dented edge metal are common at turnover.

We recommend a baseline scan within the first year. The scan records moisture, seams and flashings while everything is new. Year-five readings then have a reference point. If a leak appears, the owner can compare it against a known condition rather than guess at what changed.

The same baseline helps with warranty questions. Dated photos show what the roof looked like before a rooftop unit was added or a penetration cut. Our roof condition reports are built for that job.

Drainage deserves its own note on a new building. Construction debris, spilled sealant and stray fasteners wash toward the drains in the first rain. A clogged drain bowl on a roof this new can turn into a ponding problem within one season. We clear and photograph every drain at the baseline visit.

Down time on a line costs more than the roof repair, so the roof plan follows the line. The first questions are which bays must stay dry, which can take noise and when the plant goes quiet. Loud tear-off and deck fastening wait for those windows, and the product-contact zones under the work get temporary covers.

Open flame is rarely welcome near process lines. Welded seams and cold-applied adhesives let the crew work without it, and wherever fumes could drift toward a clean area, the intakes are located first and staging sits away from them.

Plant management and the crew agree on hold points. At each one the crew stops until someone on the plant side confirms the next step, which keeps the roof work in step with the production schedule.

Large low-slope roofs catch wind at corners and edges. Uplift peels back a perimeter flashing, then the membrane follows. After a storm we check edge metal and corners before the field.

Sherman's record shows what to expect. Spring brings North Texas its tornado peak, and one June 2025 day put an EF1 southwest of Sherman while a report near Denison measured half-dollar hail. Hail bruises insulation without always splitting the surface, so a moisture scan follows any hail report. Our hail damage repair steps begin with that scan.

Winter loads matter too. The December 2013 sleet stacked ice 4 to 5 inches deep over the Sherman and Denison area. Drains clogged with ice back water up onto a flat roof and add weight to the deck. We clear drains before the cold season.

A repair fits dry insulation and a few failed details. A coating fits a sound membrane that needs a fresh surface, and it can cut heat on the roof. A recover fits a sound deck under a tired sheet. A replacement fits wet insulation or a failed deck.

Four drivers set cost: how wet the board is, how many penetrations the roof holds, how much equipment must be moved, and how much production must stay running. We price each separately, and we confirm the city's permit requirements before pricing a replacement.

Moisture decides the order of work. If a scan finds wet board in only two bays, only those bays need tear-off, and the dry ones can be coated or left alone. A phased plan spreads cost across budget years and keeps the roof covered at every stage. We write the phases down with their triggers, so the owner knows what moves a bay from watch to repair.

Progress Park sits within Sherman. Foundation Business Park in Denison serves a similar mix of manufacturing and distribution users. Owners with plants in both can keep one roof record and one ranked repair list.

Why does a plant roof leak when no one sees a hole?

Damp air from inside can condense in the insulation. The stain looks like a leak. A scan and cores separate vapor from water entry.

What wears first around an exhaust fan?

The membrane in a ring around the opening. Warm discharge breaks it down. Curb corners and gaskets follow.

Does a new industrial roof need a survey?

A baseline scan is wise. Trades leave punctures and dents during construction. The scan records them while the roof is new.

Can production continue during a reroof?

Often, yes. The work runs in sections with daily seals. Plant management sets hold points and quiet hours.

When is a coating a better choice than replacement?

When the insulation is dry and the membrane is sound. A coating seals small flaws and reduces surface heat. Wet board rules it out.
