TPO, EPDM and Modified Bitumen Specialists
Flat roofing in Marietta, GA serves the city's commercial buildings, retail centers, warehouses and the low-slope additions on many homes. These roofs are really low-slope systems, and they live or die by seams, drainage and flashing details — not by the membrane's headline thickness. Clark Brothers Roofing installs and repairs the three proven systems: TPO, EPDM and modified bitumen.
Each system in this guide gets its own honest section below — strengths, weaknesses, ideal buildings — because flat roof sales usually push whichever membrane a contractor prefers. Georgia's heat and sudden downpours punish poor drainage and weak seams, so the assessment matters as much as the material. Call +1 470-613-9333 from our Powers Ferry Rd base for a documented flat roof assessment. We also maintain and coat flat roofs that still have sound structure beneath them, which is often the smartest money a building owner can spend.
TPO is a single-ply membrane whose seams are heat-air welded into a continuous sheet, the strongest seam method in single-ply roofing. Its white, reflective surface reduces heat load on Marietta buildings through long Georgia summers, and it resists punctures and chemical exposure common around rooftop equipment. TPO dominates new commercial construction for good reason. Its maintenance priorities are seam probing, keeping welded patches compatible, and watching areas around curbs and pipes where installers' detail work decides how the roof ages.
EPDM is a synthetic rubber membrane with one of the longest service records in low-slope roofing; properly installed EPDM roofs routinely serve for decades and aged material stays flexible and repairable. Its seams are taped or glued rather than welded, which places a premium on seam maintenance as the system ages, and its standard black surface absorbs heat — acceptable under ballast or on many industrial buildings, a consideration on sun-baked retail roofs. For owners who value longevity and repair simplicity, EPDM remains a serious option.
Modified bitumen builds a roof from multiple asphalt-based plies reinforced with polyester or fiberglass, finished with a granule-surfaced cap sheet. That redundancy is its appeal: a surface puncture rarely means a leak because another ply sits beneath, and the cap sheet tolerates the foot traffic of frequently serviced equipment better than single-ply membranes. It is an excellent fit for smaller commercial roofs, plaza decks and low-slope residential additions. Weight is higher than single-ply, so deck capacity is checked before specifying it.
Whatever the membrane, flat roof failures concentrate in the same places: standing water that has not drained within about 48 hours, seams, and penetrations for vents, drains and HVAC curbs. Ponding adds structural weight, degrades membranes faster and turns pinholes into leaks, so we map ponds during assessments and address drainage — tapered insulation, drain additions or corrections — as part of the system. Leak tracing on flat roofs follows the same discipline as pitched work: the interior drip is evidence, not a location.

A Marietta Roofer, Up Front About Everything
Clark Brothers Roofing is based at 1122 Powers Ferry Rd in Marietta, GA 30067, and this page is about how we work rather than a polished origin story. We inspect roofs carefully, photograph problems instead of describing them from the driveway, explain repair-versus-replace honestly, and put pricing in writing. If a roof has good years left, we will say so — even when a replacement would pay us more.
We are also up front about the trade itself. Georgia does not license roofers, prices in this market vary wildly, and storm season brings out-of-town crews who disappear. Our answer is simple: local address, published phone number +1 470-613-9333, open 24 hours, and business licence and insurance certificates available on request for every customer who asks. That approach shapes everything on this page: how we inspect, how we price, and how we handle the paperwork Georgia homeowners actually need.
Every job starts with a real inspection: shingles, flashing, valleys, vents, decking where accessible, and the attic side when a leak is involved. You get photos and a plain-language explanation of what is failing, what is cosmetic, and what can wait. Then you get options — repair, maintenance or replacement — each priced separately, so you can choose the scope instead of being sold the largest one by default.
Many roofing websites imply a state licence that does not exist. Georgia does not license roofers; roofing is a traditional specialty trade under O.C.G.A. 43-41-17. We will not dress that up. What we can show you is our business licence and current insurance certificates, on request, before you sign anything. Ask any roofer you interview for the same documents — a legitimate local company will hand them over without hesitation.
As of October 2026, our published ranges are architectural shingle at $4.50–$7.00 per square foot installed, typical replacements at $12,000–$22,000, and most repairs at $300–$1,500. Quotes are calculated from measured roof area, not living area, and include tear-off, underlayment, drip edge and ventilation checks. If a permit applies to your parcel in the City of Marietta or unincorporated Cobb, we confirm that before quoting rather than adding it later.
Our base at 1122 Powers Ferry Rd puts us minutes from East Cobb, the Marietta Square, Franklin Gateway and the I-75 and I-285 corridors. We work on the housing stock we know: Marietta homes with a median year built around 1984, Cobb homes around 1989, layered shingle roofs, aging flashing and heavy tree cover. Local means accountable — you know where to find us after the job, not just during it.

A tree limb through the roof or water pouring through a light fixture turns a home into a triage problem. The first hour matters, but almost everything useful in that hour happens inside the house, not on the roof. Wet roofs are fall hazards, damaged decking can give way, and electrical hazards hide in wet ceilings.

Clark Brothers Roofing is open 24 hours at 1122 Powers Ferry Rd, Marietta, GA 30067. Call +1 470-613-9333, describe what you are seeing, and keep this guide open while you wait for help to arrive.
Key points
Get everyone, including pets, out of rooms with sagging ceilings, active drips near fixtures, or visible structural damage. A bulging ceiling holds pooled water and can release it all at once, so do not stand under it and do not push on it except as described below from a safe position. If water is reaching outlets, switches, or the panel area, or you smell electrical burning, leave the area and call emergency services or your utility. No roof repair is worth an electrical or collapse injury.
Contain, do not chase. Place buckets under drips, line the floor with plastic, and move what you can. If a ceiling bulge is growing, a careful puncture at its lowest center with a screwdriver, from the side rather than directly underneath, can drain pooled water into a bucket in a controlled way instead of letting the drywall fail on its own. In the attic, if and only if access is safe, dry, and lit, a container under the entry point can limit spread. Otherwise stay out and let the crew handle it.
A tarp helps only if it is installed safely and anchored without creating new damage. Never go onto a wet, steep, or structurally damaged roof yourself, and be wary of anyone offering to nail a tarp through sound shingles without explaining the anchor method, since every nail hole is a future leak path. Proper emergency tarping weights or anchors at edges, extends well past the damage, and sheds water over, not under, the courses below. If a tree is involved, the removal and the roof work need coordination so the tarp is not torn off with the limb.
Before cleanup erases the evidence, photograph and video the damage from inside and from the ground outside, including the object that caused it, debris in the yard, and water-affected rooms. Save the date and the storm details. Then call your roofer first for emergency mitigation and documentation, and notify your insurer promptly. Keep receipts for emergency work: under Georgia's HB 423 framework, emergency work is treated separately from a full contract, and payment questions after a denial follow specific rules your documentation supports.
The facts in this guide are drawn from the official and primary sources below, checked October 2026.
Roofs rarely fail without warning. They fail after a season of small warnings nobody looked at: a cracked boot, a lifting valley edge, granules thinning at the eaves. A regular inspection cadence catches those while they are still in the $300 to $1,500 repair range instead of the ceiling-and-decking range, which is the entire economic argument for inspections.
Marietta's tree canopy, pollen, heat, and storm history argue for a specific rhythm: a routine check on a set interval, an extra check after any serious storm, and a planned check before you buy or sell. This guide sets out that cadence and what a thorough inspection should actually cover. To book one with Clark Brothers Roofing, call +1 470-613-9333.
For most Marietta homes, schedule a professional roof inspection once a year, ideally in spring before the heaviest storm season or in fall before winter rain sets in. Homes under heavy tree cover, roofs over 15 years old, and roofs with a history of leaks benefit from twice-yearly attention because debris load and aging components change faster. Between professional visits, your own ground-level look after storms, checking for tabs in the yard, gutter overflow, and new ceiling stains, fills the gaps at no cost.
The calendar does not override events. Any storm with hail at or above 1 inch, like the 1.00-inch hail in Due West on September 12, 2023, or winds strong enough to scatter debris and damage trees, earns an inspection regardless of when the last one occurred. Wind creases tabs and breaks sealant bonds invisibly from the ground, and hail bruises mats in ways that shorten roof life without leaking immediately. An after-storm inspection documents condition with dates, which matters if damage later becomes a claim.
Roof condition is one of the first things buyers, lenders, and insurers ask about, and surprises here delay or kill transactions. Sellers should inspect before listing so repairs can be made calmly and documented, rather than negotiated under deadline. Buyers should insist on a roof-specific inspection beyond a general home inspection, since general inspectors often view roofs from the ground. Also schedule a check as a roof crosses 10, 15, and 20 years: insurers apply ACV age schedules at those marks that can cut value by 40 to 60 percent, and knowing condition early preserves options.
Expect more than a glance. A complete inspection examines shingle condition and granule coverage, tests sealant bonds, checks every penetration and boot, inspects flashing at walls and chimneys, walks valleys, reviews ridge and ventilation against the 1/150 baseline, looks in the attic for stains, dampness, and daylight, and checks gutters and soft metals for storm evidence. You should receive photos and a written summary separating urgent repairs, watch items, and remaining-life observations. If the report is a single sentence and a price, it was not an inspection.
Start with the fact most homeowners get wrong: Georgia does not license roofers. Roofing falls under the traditional specialty exemption at O.C.G.A. 43-41-17, so there is no state roofer's licence to ask for, and any contractor implying otherwise is telling you something about their honesty. Vetting here means checking the credentials that do exist.
The good news is that a real checklist exists: local business licence, current insurance certificates verified directly, a Georgia Secretary of State business search, and a written scope that names code items like drip edge. This guide walks through each check and the red flags, including the illegal deductible waiver. Clark Brothers Roofing welcomes every check on this list; reach us at +1 470-613-9333.
Ask for the contractor's local business licence (often called an occupation tax certificate) and verify the business exists and is in good standing with a Georgia Secretary of State business search, which takes minutes online. Then request certificates of insurance, general liability and workers' compensation, and verify them with the issuing agent rather than accepting a photocopy at face value, since certificates can be outdated or borrowed. Confirm the legal business name and physical address match across the licence, the insurance, the SOS record, and the quote.
A trustworthy quote names its components: tear-off or overlay, underlayment type, drip edge, flashing treatment, ventilation approach, and cleanup and disposal. Drip edge is required in Georgia under R905.2.8.5, so its absence is a competence flag. The scope should state how many layers are present, how decking replacement is priced if found, and which permit office covers your parcel, since the City of Marietta and unincorporated Cobb differ. Vague one-line quotes protect the contractor, not you, when surprises appear mid-job.
In Georgia, waiving or absorbing your insurance deductible is illegal, so a contractor offering it is offering to commit fraud with your policy, and the inflated invoice that hides it becomes your problem. The same goes for 'free roof' pitches after storms and pressure to sign an assignment of benefits on the spot; SB 201, effective July 1, 2025, added protections and AOB limits in declared-disaster counties for a reason. Also walk away from anyone who offers to negotiate your claim: in Georgia that role belongs to licensed public adjusters and attorneys only.
Favor a contractor with a real local address you can drive to, a phone that is answered, and documentation habits: photo inspections, written findings, and photo reports on completion. Ask how they handle the call six months later if a repair leaks. Storm-chasing operations dissolve before warranties matter, while a Marietta-based company has a reputation on your street to protect. Clark Brothers Roofing is based at 1122 Powers Ferry Rd, Marietta, GA 30067, is open 24 hours, and can be reached at +1 470-613-9333. Vet us with this same list.
Homeowners can do genuinely useful leak detective work without ever stepping on the roof. Mapping the stain, checking the attic safely, and photographing the slopes from the ground give a roofer a head start and sometimes reveal an obvious cause like a debris-choked valley. The diagnosis is DIY-friendly; most of the fixing is not.
This guide draws the line clearly: what to check, what never to do, and the signals that mean call a professional now. Smearing tar on a shingle or walking a wet roof in the rain causes more damage and injury than any leak. If your checks point to the roof surface, call Clark Brothers Roofing at +1 470-613-9333 for leak detection and repair.
For most buildings, TPO offers the best mix of welded-seam reliability, reflectivity and cost. EPDM suits owners who value its long track record and repairability, and modified bitumen wins where foot traffic is heavy. The right answer depends on your equipment layout, traffic and budget — we lay the options out system by system rather than selling one default.
Technically water should clear within 48 hours of rain ending. Persistent ponding means a drainage or slope problem: it adds weight, accelerates membrane aging and finds pinholes. Solutions range from tapered insulation and added drains to targeted re-sloping, and the right one comes from mapping the pond during an assessment.
Often, yes, if the existing system and insulation are dry and sound. A professional coating system can restore waterproofing on aging TPO, EPDM, modified bitumen and metal at well below tear-off cost. Wet insulation or deck failure disqualifies a roof, and we verify condition before recommending coating — see our roof coating page for the full process.
It depends on the system: welded TPO seams, glued or ballasted EPDM, and multi-ply modified bitumen each price differently, and insulation and deck condition drive the total. Because of that range, we quote flat roofs from a measured assessment in writing rather than publishing a misleading per-square-foot figure. Call +1 470-613-9333 to schedule.
Start dry and on foot. In the attic during daylight, look for dark streaks on rafters, damp or matted insulation, moldy decking, and pinpoints of daylight, working from the stain location uphill. On the ceiling below, outline the stain lightly in pencil and date it, so you can tell after the next rain whether it grew. From the yard, photograph each slope, valley, chimney, and vent with a zoom lens, and note which downspouts overflow. This record, stain map, attic findings, dated photos, is exactly what speeds up a professional trace.
A few fixes are legitimately yours. Clear gutter overflow by cleaning gutters from a stable ladder at the eave, following ladder safety basics, or hire it out. Note debris dams visible in valleys and tell your roofer rather than raking them from a ladder. Inside, manage water with buckets and protect finishes. What you cannot fix from the ground is the entry point itself: boots, flashing, valleys, and shingles live on the slope, and that is where the boundary sits for both safety and workmanship.
