Flat and low-slope roofs fail differently than pitched roofs. Water doesn't run off — it sits, finds seams, and works its way in. Eagles Roofing installs and repairs single-ply membrane systems built to shed standing water and survive the UV load that bakes down on North Georgia rooftops all summer.
Whether it's a Cartersville storefront, a warehouse off the I-75 corridor, or a low-slope residential section, we diagnose the real drainage problem and install a system that solves it — TPO, EPDM, or modified bitumen — with heat-welded seams and correctly detailed flashings.
Signs Your Flat Roof Needs Attention
- Ponding water that sits for more than 48 hours after rain
- Blistering, cracking, or seam separation in the membrane
- Interior leaks and water stains below the roof deck
- Membrane pulling away from parapet walls or curbs
- Chalky, brittle surface from years of UV exposure
- Clogged or undersized drains and scuppers
Membrane Systems We Install
TPO is our most-requested single-ply membrane — a bright, reflective white surface that bounces heat, with heat-welded seams that create a monolithic, watertight sheet. It's an excellent fit for commercial buildings and modern low-slope homes across Bartow County.
EPDM (rubber) roofing is a proven, flexible system that handles temperature swings well, and modified-bitumen is a rugged, torch- or self-adhered option for smaller low-slope sections. We match the membrane to the building's use, foot traffic, and budget.
Fixing the Real Problem: Drainage
Most flat-roof failures trace back to water that has nowhere to go. Before we install a single square foot of membrane, we assess slope, drains, scuppers, and tapered insulation so water actually leaves the roof. Skipping that step just puts a new membrane over an old ponding problem.
We detail every penetration, curb, and parapet — the spots where leaks actually start — and we can add tapered insulation to build positive drainage where the deck is dead flat. The result is a roof that drains, not one that just waits to leak again.
Correcting Ponding With Tapered Insulation and Real Drainage
Low-slope roofs don't shed water the way a pitched roof does, so the entire system lives or dies on drainage. Standing water, ponding that lingers more than a couple of days after rain, is the enemy: it accelerates membrane aging, concentrates weight, finds every seam, and on TPO and EPDM it's a warranty issue the manufacturer will point to. The usual culprits are a dead-flat deck, drains set too high, or insulation that's gone flat and waterlogged. We don't just re-cover over a ponding problem; we diagnose where water wants to go and build positive slope toward it.
The fix is tapered insulation. We lay out a taper system, typically around a quarter-inch-per-foot slope with crickets and saddles between drains and around curbs, so water is actively steered to the outlets instead of pooling in the field. That rebuilds pitch without touching the structural deck, adds R-value, and gives the membrane a clean, dry plane to bond to. We pair it with properly flashed drains or new scuppers sized for our downpours. TPO's heat-welded seams and EPDM's bonded laps are both durable, but only a membrane that actually drains delivers the service life you're paying for.

What Affects the Cost
We never quote a real roof from a phone call. Instead, here are the honest factors that shape your price — all assessed during your free inspection so you get a firm, written number with no surprises.
Membrane type
TPO, EPDM, and modified bitumen each carry different material and labor costs.
Roof size & access
Square footage, rooftop equipment, and access for materials drive the labor estimate.
Drainage corrections
Adding tapered insulation, drains, or scuppers to solve ponding is often part of the fix.
Insulation & tear-off
Removing a failed system and upgrading insulation affects the total scope.
Common Flat Roofing Mistakes We Fix
A lot of our work is correcting shortcuts other crews took. Here are the mistakes we see most on flat roofing jobs around Cartersville — and how we do it right instead.
Coating over wet insulation
When a low-slope roof has saturated insulation, crews often spray a fresh coating right over it to make it look new. The trapped moisture blisters the membrane, rots the deck, and grows mold underneath. Eagles probes for wet insulation first, removes and replaces the saturated boards, and only then installs the membrane or coating over a genuinely dry, sound substrate.
Reverse-lapping the seams
On membrane roofs, an inattentive crew can lap a sheet so the upslope edge sits under the downslope one, aiming water straight into the seam. It looks finished but channels water into the lap. We run and weld seams so every lap sheds downslope, then probe-test the welds, ensuring water always rides over a seam rather than being funneled into it.
No termination detail at the walls
Flat roofs frequently fail where the membrane meets a parapet or wall because crews just glue it up and hope. Without a termination bar and counterflashing, the top edge peels and water runs behind the membrane. Eagles carries the membrane up the wall to proper height, locks it with a termination bar, and caps it with counterflashing so the vertical transition stays sealed.

That is how a flat roof survives North Georgia's heat and heavy rain without blistering or leaking. Licensed, insured, and backed by a free 21-point inspection. Call (855) 705-1940.
Flat Roofing FAQs
How long does a TPO flat roof last?
A properly installed TPO membrane commonly lasts 20 to 30 years, depending on the membrane thickness, how well the roof drains, and rooftop foot traffic. Solving ponding water and detailing the flashings correctly is what determines whether it reaches the top of that range.
Why does water pond on my flat roof?
Flat roofs are never truly flat — they need a slight slope toward drains. Ponding usually means the slope, drains, or scuppers are inadequate or clogged. We correct drainage with tapered insulation and proper drains so water leaves the roof instead of sitting on it.
Can you repair my flat roof instead of replacing it?
Often yes, if the membrane is still sound and the leaks are localized to seams or flashings. We assess the whole system and give you an honest repair-vs-replace recommendation based on the membrane's remaining life.
There's always a puddle on my flat roof after it rains. Is that normal or a problem?
A puddle that clears within about 48 hours of a storm is generally acceptable. Water that sits for days is ponding, and it's a real problem, it shortens membrane life, adds load, and can void your material warranty. It usually signals a slope or drainage defect that a simple re-coat won't solve. We correct it with tapered insulation and proper drains rather than covering it up. Call (855) 705-1940 and we'll evaluate the drainage.
How often should a flat or low-slope roof be inspected?
At least twice a year — spring and fall — plus after any major storm. Flat roofs fail at seams, flashings, and drains long before the whole membrane goes, so catching a small issue early is far cheaper than an interior leak. Ask us about a maintenance schedule at (855) 705-1940.
