Commercial Roofing in Sandtown Crossing, South Fulton, GA
A new tenant means new roof penetrations. Sandtown Crossing is an area of existing shopping and residential development. South Fulton's strategic plan pairs it with an 85-acre passive-park component and identifies room for more retail and restaurants. The city's 2025 business announcement called the shopping center an active retail destination and announced a new retail opening there. Each opening brings a fit-out. Each fit-out can touch the roof. We start with the use below the roof zone, then name what the new tenant will add above it.
Building use: what a fit-out does to the roof
A tenant moves in with equipment. A rooftop unit needs a curb. A kitchen needs an exhaust fan and a makeup air unit. A cooler needs a condenser. Plumbing vents, gas lines and conduit all rise through the deck.
Each penetration is a seam that must stay sealed. Each curb is four corners. A fit-out that adds six items adds six places for water to enter. The roof record should show them all.
We map penetrations before a fit-out starts. We photograph existing curbs. We note abandoned ones from a former tenant. The map tells the mechanical contractor where the deck is open and where it is solid.
Make-ready between tenants is the best time to fix the roof. The unit is empty. Access is easy. A leak history is fresh. We recommend a short roof check at each turnover. It costs little and sets a clean start for the next tenant.
Roof mechanism: curb flashing and repeated service
Curb flashing is a common leak path on retail roofs. The sheet turns up the curb and is sealed at the top. Heat moves the curb. Sealant hardens. The corner opens.
Service visits add wear. A technician walks to a unit, kneels and sets down tools. A worn path forms. Membrane scuffs at the curb base. Grit grinds into laps.
We protect the route. Walk pads run from the hatch to each unit. A log at the hatch names each visit. When a puncture appears, the log narrows the list. Our rooftop equipment curbs and supports work raises lines off the sheet and rebuilds failed corners.
Signs add load. A storefront sign bolts through a parapet or canopy. A new sign means new holes. The holes need flashing or a curbed support, not caulk alone. We check each sign mount during a fit-out and note any that moves in wind.
Restaurant pads: grease, exhaust and drains
The plan identifies room for more restaurants. A restaurant roof has its own mechanism. Exhaust throws grease onto the sheet. Some membranes soften. Drains downwind clog. Rain carries grease to the low point.
The first walk looks at the fan curb, the grease path and the nearest drain. Softened sheet is cut out. Grease-resistant material goes in its place. A containment tray is added where none exists.
Cleaning helps. The exhaust vendor and the roofer can share a schedule. The roof gets cleaned on the same visit. That saves a second lift and a second closure on a restaurant roof.
Inspection findings: what the first walk marks on a center roof
A center roof has a long run of shared parapet. It also has many small roofs. The first walk covers both. We photograph each bay from a fixed point. Then each curb, each drain and each penetration.
Common marks include open cap joints and cracked boots. Curb corners split. Scuppers sit high. Sealant at terminations dries out. Terminations get a press test and laps get a probe. Water poured at each drain shows the flow.
Shared walls get a note. Flashing at a common wall depends on two owners. A commercial roof leak repair there begins by confirming which roof the water entered. Water can travel along a parapet and appear next door.
The walk ends with a one-page summary and a longer record. The summary separates sound areas, repair items and watch items.
Timing: heat, humidity and the spring storm window
Hot, damp summer afternoons age boots and sealants, and Atlanta tops 95 degrees on about seven of them in a typical year. Humid air slows cure, so heavy tie-ins go on in the morning and the open area is sealed before storms arrive.
Spring is the severe window. North and central Georgia sees large hail on roughly seven days a year, peaking in April, and tornadoes are on record for every month, clustered in March through May. A retail roof with rooftop units has many targets for hail. We inspect after each event and compare the roof to its baseline. A hail damage review takes surface samples and reads a moisture meter under each mark.
Edge metal takes wind first. We test every coping length by hand. Open joints and loose cleats are listed. A heavier cleat costs little. A lifted membrane costs a great deal.
Access and sequencing: open stores, busy lots
A shopping center stays open. Customers park near the work. Deliveries arrive on schedule. Tenants have quiet hours.
We agree on a staging area first. We close only the stalls we need. We place barriers on the first morning. We set a pedestrian path past the work. Loud steps run before opening or after close.
Residential neighbors are close in a mixed area. Noise and dust travel. The work window is posted. Intakes stay covered while adhesive is used. Each day's close-in point is written down.
Weather windows run tight in humid months. Afternoon storms build fast. Each night the roof is closed in. Materials stay covered. Tools are secured. If a front moves in early, we stop at the last close-in point.
Send the mechanical plan, curb list and the access window
What should a GC send for a tenant fit-out that touches the roof?
Send the mechanical plan, curb locations, loading limits and the access window. We recommend adding the existing roof plan. With those, we mark penetrations and set the work order.
How do you handle abandoned curbs from a former tenant?
We map them, check the flashing and recommend removal or capping. We recommend doing it in make-ready, before the new tenant's unit goes in.
Can grease damage be repaired without replacing the roof?
Often yes. We cut out softened sheet and replace it with grease-resistant material. We recommend a containment tray and a cleaning schedule.
Who pays for shopping center roof work?
The lease says. Many leases pass roof cost through common charges. We recommend a dated record so the landlord can show what was done.
When should a retail roof be inspected?
Before March and after each severe storm. We recommend a full photo pass and a moisture scan each spring.
What does a turnover roof check include?
A photo pass of curbs, penetrations and drains, a look at abandoned equipment and a note on sealant. We recommend doing it before the next tenant's contractors go up.
