Grocery Store Roofing in Pompano Beach, FL
Two days after a hurricane, the one door in the neighborhood everybody expects to be open is the grocery store. People in Pompano Beach, FL need ice, water, milk and bread, and a store with a damaged roof has to choose between a wet floor and a locked door. Hurricane Wilma crossed South Florida in October 2005 with an eye that covered most of Broward, and roof damage was reported across the county. A store whose roof lets go in a storm like that has no good way to open its doors.
We repair, recover and replace roofs on grocery stores, from the neighborhood market to the supermarket at the head of a plaza. The roof of a food store has jobs a roof on an office does not: it carries heavy refrigeration, it protects open food, and it has to be dry when the power comes back on.
Open After the Storm: why a grocery roof cannot wait
A grocery store carries its worth in a few days of perishable stock, and a roof leak turns that stock into a loss quickly. Ceiling tiles over aisles absorb water and fall, drips land on shelves and cases, and the floor becomes a slip hazard that stops customer traffic. A leak that a warehouse might live with for a week can close a food store in an afternoon.
That is why we put grocery roofs on the front of the list before hurricane season. We look at the edges first, since wind like Irma's 2017 gusts of 80 to 100 mph across Broward goes after perimeter metal before anything else, and then at drains and every unit on the roof. When a storm has passed, our emergency roof repair crews dry-in the damaged area so the store can get back to selling while permanent repairs are scheduled.
Cold Chain Overhead: condensers, racks and the pipes that feed them
Walk the roof of a supermarket and you find the other half of the refrigeration system. Condensers, rack equipment, exhaust fans and long runs of refrigerant line leave the building through the roof, and each place a line crosses the membrane is a penetration that has to stay watertight under constant vibration and heat. Dewpoints in the 70s, hot nights and near-daily summer thunderstorms keep that equipment working harder than it does in cooler places.
Roof traffic is the second problem. Refrigeration technicians climb up several times a month, and without walk pads they wear a path through the membrane. We install pads where the traffic is, check each curb and support for flashing and tie-downs, and make sure refrigerant lines and conduit are carried on supports that lift them off the membrane. The roof can do its part of a cold-storage building's job as well, which is to keep warm, wet air from reaching the insulation.
Dry Floors, Clean Product: what a leak means in a food building
Water in a food building is a food-safety issue before it is a repair issue. A drip over an open produce table or a bakery case can mean pulling product, closing an aisle and calling the store manager before the roofer has even arrived. Slow leaks are worse in some ways, because wet insulation above a drop ceiling can sit unnoticed until it shows up as a stain or a musty smell.
An infrared moisture survey flown or walked just after sunset picks out the wet insulation, so only the saturated squares get cut out and replaced. On a store with a long history of small leaks, the survey can reveal a pattern: water entering at one flashing and traveling across the deck to a spot over the dairy case. We deliver photos and a marked-up roof plan so the store's facilities group can see what we see and make decisions with the facts in front of them.
Early Hours: roofing while the produce truck backs in
A grocery store is busy at hours when other buildings are dark. Deliveries arrive before dawn, stockers are on the floor overnight, and customers fill the aisles from the time the doors open until late evening. Roof work has to move around all of that, which means early starts, careful staging away from the loading dock and customer entrances, and a clean parking lot at the end of every shift.
Wet season timing sets the other edge. Mornings are usually clear, and we open only what we can dry-in before the cells build over the Everglades and roll east in the afternoon. We cover or move product below the active zone the night before, protect the sales floor, and keep fans, vents and intakes sealed from dust and fumes. If the radar turns early, the crew closes up what it opened, so the store is not left with an open roof when the sky turns.
Deli and Bakery Exhaust: grease on the membrane
Rotisserie ovens, fryers and bakery equipment send grease-laden air up through exhaust fans, and some of that settles on the roof around them. Grease softens many membranes and speeds up their wear, and a roof that looks fine from the parking lot can be failing in a ring around the exhaust fan. Over time the damage spreads to seams and flashings nearby.
The remedy is a choice of material and a cleaning habit. A membrane built to resist fats and oils, like PVC, holds up better near kitchen exhaust, and grease trays under the fan discharge catch drips before they land on the roof. We look at that part of the roof first on any store with a deli, and we add it to the preventive maintenance visit so grease gets cleaned before it gets into the seams.
Supply Side: Associated Grocers, FreshPoint and the Central 95 corridor
Pompano Beach's grocery picture does not stop at the stores. Publix, with 589 employees, and Associated Grocers, with 615, are among the city's top ten employers, and FreshPoint Produce and Dairy, at 420, joins them there. That puts a lot of food handling inside the city, and the Central 95 corridor beside I-95, home to Associated Grocers and FreshPoint distribution operations, holds the buildings that move product.
A grocer's roof problem often has a counterpart upstream. A leak at a distribution building can interrupt the supply to many stores as quickly as a storm at one of them, so owners with multiple locations pay attention to the whole chain. On distribution center roofs and store roofs alike the discipline is the same: find the water, keep the product dry, and plan the repair around the operation instead of the other way around.
Questions We Hear Often
Can a grocery store keep selling during a roof replacement?
Yes, in most cases. We work in sections, dry in each one the same day, and protect the aisles beneath. Product under an active zone is covered or moved the night before, and noisy steps start early.
Who do we call when a roof leak drips onto produce at night?
Call us any hour. A crew will cover the opening, shield what is below and photograph the damage for your records. Permanent repairs follow when the weather allows.
How do we protect refrigerated cases from a leak?
Cover the case, move product out of the drip zone, and call right away. A roofer can stop the water at the source while your refrigeration contractor checks the equipment, since both problems often show up together.
When should a grocer prepare the roof for hurricane season?
Before mid-May, when the wet season opens and the stormiest weeks begin. Clear the drains, tighten the tie-downs on rooftop units and have edge metal inspected. A short walk with photos beats a scramble in August.
Does a white roof really lower a store's cooling costs?
Light-colored membrane runs cooler under the sun, so rooftop units work a little less hard through a Broward summer. Savings vary by building, so we describe the benefit in terms of heat on the roof, not a promised number.
