Quick answer: Union City still has its railroad-era main street, but the buildings that define its water risk now are the distribution warehouses along the South Fulton Parkway and Flat Shoals corridors — single buildings approaching a million square feet under one flat roof. A ponding roof leak or a broken sprinkler line in a building that size can wet inventory across whole aisles before anyone finds it, and the small streams that cross the city, including a tributary to Wolf Creek documented in state permit filings, collect the runoff from all that new pavement. If water is spreading through your Union City building or home, call PuroClean of East Cobb at (770) 627-0900. We answer 24/7 with a live person and respond in 60 minutes or less.

The Georgia General Assembly incorporated Union City in 1908, and one account of its name credits the union of rails at a railroad junction. The rail lines never left, but in the last decade the land around them has filled with logistics buildings drawn by the airport, the interstates, and the intermodal yards nearby. The city now covers about 19.8 square miles and counted 26,830 residents in the 2020 census — while its daytime footprint is measured in dock doors and trailer courts as much as in homes.
Big roofs, fast water
A warehouse roof is a catchment. Rain that would soak into acres of ground instead lands on one membrane, runs to a limited number of drains, and ponds wherever the deck has sagged or a drain has clogged. When a seam fails or a drain backs up during a heavy storm, water enters above the ceiling plane and travels — across decking, down columns, and into racking rows that can be far from the actual opening. A single distribution building here was built at 987,840 square feet, and newer logistics centers add hundreds of thousands more; at that scale, a “small roof leak” is a relative term.
The second source is inside the building. Sprinkler mains run the length of these structures, and a struck head, a frozen section near a dock door, or a failed fitting releases water at pressure until the zone is shut down. Office build-outs, restrooms, and break rooms add ordinary plumbing to buildings that are otherwise mostly open floor. In every case the damage pattern is the same: water spreads wide and shallow, wicking into cardboard, pallet wood, drywall at office partitions, and the slab joints themselves.
Homes share the same new drainage
Union City’s neighborhoods sit in the same landscape as the warehouses, and the city’s small streams receive what all that pavement sheds. A Georgia EPD public notice for one Stonewall Tell Road warehouse project describes buffer impacts along about 407 linear feet of an unnamed intermittent stream, a tributary to Wolf Creek in the Middle Chattahoochee–Lake Harding watershed — a useful reminder that even the unnamed channels crossing residential streets are mapped parts of a drainage system. Homes near those channels, and homes downhill of new grading, can see yard and crawlspace water they never had before.
What to do in the first hour
1. Protect people and product first. Keep staff clear of wet electrical areas and move salvageable inventory out of the spread path if it can be done safely.
2. Stop the source. Shut the sprinkler zone or supply valve for a plumbing break; for a roof leak, note the entry point and place containment under the drip line.
3. Document before cleanup. Photos and video of water lines, entry points, and damaged goods protect your claim and your inventory records.
4. Call (770) 627-0900. Commercial extraction and drying at warehouse scale needs truck-mounted capacity and moisture mapping across the whole spread, not a mop crew.
