Commercial Roofing in Cedar Cove Technology Park, Tuscaloosa, AL

A supplier plant in Cedar Cove Technology Park has a roof that works as hard as its production floor: a wide low-slope field carrying exhaust fans, make-up air units and a forest of curbs, all of which a superintendent counts before looking at anything else. The 950 acres of Cedar Cove Technology Park reach from Progress Drive to Ed Stephens Road, a mile off I-59, and buildings there that supply the Mercedes plant at Vance are the kind that run tight schedules where a leak is unwelcome.

Plans have named SMP Automotive Systems for a 700,000 square foot Mercedes-supplier facility in the park, and Faurecia for a plant just south of the I-20/59 rest stop, some 3.5 miles west of the Mercedes plant. A supplier plant is watched closely by managers who want to hear about roof problems before production does, and the walk is built to give them that notice.

A first walk puts the roof on paper, curb by curb, with the date.

Rooftop Equipment and Curbs

On a manufacturing roof the curbs are the story. Each rooftop unit, exhaust fan and make-up air box sits on a curb with its own flashing, sealant and fasteners, and each one is a place where water can enter or where heat and vibration can loosen a joint. Every one is counted, numbered on the plan and scored by itself.

A curb that was flashed in good weather and never revisited is a common finding on a young roof. Sealant dries and cracks, base flashing separates from the curb wall, and counterflashing pulls loose. We probe each joint, photograph the worst and mark the ones that need attention this season.

Equipment changes are the other recurring item. A plant adds a line, a unit is replaced or a duct is rerouted, and the openings that result are only as good as the work done around them. The log records each change, so the next walk starts from what is true, not what the drawings say.

For a facility manager, the output is a numbered list tied to the plan: curb 14 has open sealant on the north corner, curb 22 has a lifted counterflashing, curb 31 is sound. A list like that is something a maintenance team can act on in a day.

Loads, Supports and Walkways

Heavy equipment loads a roof differently from a field of membrane, and on a long span a point load from a unit can deflect the deck. Crushed insulation under a support, cracked cover board and ponding beside the heavy gear are the clues that the deck or the support is straining.

Service routes matter as well. Technicians cross the same path to reach units week after week, and without walk pads the membrane wears through to its reinforcement. We mark the worn routes on the plan and recommend pads where the wear shows, and the rooftop equipment curbs and supports work includes raising or rebuilding a support when the roof beneath it has failed.

Where a plant expects to add or move equipment, we ask for the plan before the unit is set, so that curbs, flashing and drains are laid out around the new load.

Insulation under a support can compress over time, so the unit sits lower on one side and water ponds against it. Measuring the tilt of a unit is a quick check, and a visible tilt is a reason to raise the support before the seam fails.

Exhaust, Heat and Chemical Exposure

Manufacturing exhaust can attack a membrane. Warm, damp or chemical-laden air from a vent settles on the roof near it, and the surface there can blister, discolor or soften. We score the area around each vent separately and note any change, so that the cause can be identified and a material chosen that can stand up to it.

Tuscaloosa’s climate adds its own load. A membrane here sits through wet seasons that add up to about 53.5 inches and summers that have touched 107 degrees, and heat from the plant below plus sun above is what cracks sealant at the curbs.

A PVC roof is one option where grease or chemicals reach the surface, and the walk tells us whether a repair, a recover or a different membrane suits the building.

Roof drains near exhaust areas clog with whatever the plant vents, so their baskets are checked more often and the log shows the dates.

Wind and Roof Securement

The April 27, 2011 tornado carried estimated 190 mph winds, and a county survey after the May 2025 storm found straight-line gusts between 90 and 100 mph. Neither measures a roof in Cedar Cove, yet both explain why the uplift rating of each section and the state of its edge metal belong in the file.

On a big plant roof, the corners and perimeter see the highest uplift pressure. We pull fasteners along the perimeter row, check cleats and coping, and mark any run that needs more securement. A roof that passes a pull test is documented as such, and a roof that fails gets a plan.

Rooftop equipment is secured to the curb and the curb to the deck. We check hold-downs, screens and tie-downs on the units themselves, since a loose panel in a gust is a hazard to the roof beneath it.

Roof hatches and any skylights come next. A hatch that will not seat, or a skylight curb with failed sealant, lets in wind-driven rain and gives uplift a grip.

Each result is written next to the section name, so the ranked list shows which parts of the roof are tied down well and which are not.

Turnover, Warranty and Records

New plants often change hands from builder to owner with a roof warranty and not much else. We walk the roof at turnover, photograph every curb and drain and take cores at representative points, so the owner has a baseline before the first production line starts.

The roof warranty management file keeps the manufacturer’s terms, the notice period and the allowed repair methods in one place. Repairs follow the published method, and each is logged with photographs.

For owners with sites in the Airport Industrial Park and nearby Vance, a shared format lets the asset manager compare roofs across the supplier network.

If a plant is leased rather than owned, the baseline protects both parties, because it shows what the roof was when the tenant arrived. A preventive roof maintenance schedule then sets who checks which drains and when.

Commercial Roofing Questions

What is the first thing counted on a plant roof?

The curbs. Each rooftop unit, fan and vent gets a number on the roof plan and a score for its flashing and sealant.

How do exhaust vents affect a membrane?

Warm, damp or chemical air can blister or soften the surface nearby. We score the area separately and note any change.

Is a recover possible over an equipment-heavy roof?

Sometimes, if insulation is dry and the deck can carry the load. Cores and a moisture scan decide.

When do equipment changes need a roof plan?

Before the unit is set. Curbs, flashing and drains are easier to lay out first than to fix afterward.

What do you need to begin?

A building list, the newest roof report and a contact for cranes and access. Photographs and notes go into the roof file so the next walk can compare.
