Roofing in Marietta, GA

What a roof costs in Marietta
A full tear-off and replacement in Marietta runs $10,200–$19,100 for architectural asphalt shingles on a 2,000–2,500 sq ft home. Such a footprint carries roughly 22–28 squares of actual roof surface once pitch and waste are counted, which puts the same job at about $405–$758 per square — the unit a contractor's estimate will be built in.
That midpoint sits 14% below the $17,100 median across the 935 cities researched on this basis, placing Marietta in the 9th percentile for asphalt replacement cost.
Within Georgia, it runs 9% higher than the $13,425 median across the 56 Georgia cities covered here.
| Material | Installed range | Service life | Best suited to |
|---|---|---|---|
| 3-Tab Shingles | $8,000 – $15,200 | 15–22 years | Budget-first replacements on simple rooflines and rental properties. |
| Architectural Shingles | $10,200 – $19,100 | 24–32 years | Most common Georgia choice balancing durability, curb appeal, and cost. |
| Impact-Resistant Class 4 | $12,000 – $23,400 | 30–40 years | Storm-prone corridors and owners prioritizing hail and wind resilience. |
| Corrugated Metal | $9,200 – $23,800 | 35–50 years | Low-maintenance performance and strong rain-shedding on secondary structures. |
| Standing Seam Metal | $16,400 – $40,100 | 45–70 years | Long-term ownership, premium durability, and strong wind performance. |
| Synthetic Slate | $19,200 – $49,600 | 40–60 years | Premium aesthetics for historic or luxury homes without natural-slate weight. |
On what is and isn’t included
The $10,200–$19,100 band covers tear-off, underlayment, the new covering, disposal, and labor on a 2,000–2,500 sq ft footprint. It excludes deck replacement — on a Marietta roof at this price, budget a further $612–$2,292 if the sheathing is soft.
Installed cost divided by service life, using Marietta’s own figures. Corrugated Metal works out cheapest per year at about $388 — even though it is not the cheapest to buy. The bar shows best case to worst case; the dot is the midpoint. All of it assumes the roof reaches its rated life, which depends on the installation more than the product.
Each tick is one of the 935 cities researched on the same basis. Marietta sits at the 9th percentile.
What moves the number in Marietta
The $10,200–$19,100 band above assumes a straightforward roof. These are the items that move a Marietta quote off it, priced against that same range rather than a national percentage.
| Cost driver | Effect | Why it costs what it does |
|---|---|---|
| Steep pitch (7:12 and above) | +$1,612–$2,784 | Staging, slower coursing, and fall-protection time. On a $14,650 Marietta roof that is the largest single geometry premium. |
| Removing a second layer | +$918–$3,056 | Tear-off and disposal roughly double. Ask whether the $10,200–$19,100 quoted assumed one layer. |
| Sheathing replacement | +$612–$2,292 | The most common change order, priced per sheet once the deck is open. At $14,650 for the roof itself, an undisclosed sheet rate is where a Marietta quote quietly grows. |
| Two-story access | +$879–$1,465 | Longer material handling on every course, worth roughly $1,172 on this range. |
| Class 4 impact-resistant upgrade | +$1,800–$4,300 | Taken from the Marietta table above. Whether a carrier credit offsets that $1,800 depends on your own policy — price it, do not assume it. |
| Standing seam metal instead of asphalt | +$6,200–$21,000 | Roughly double the service life, so the comparison is $543 a year against $417 a year, not the sticker price. |
What the weather does to roofs in Marietta
Across the 1991-2020 climate normals, Marietta averages summer highs averaging 84°F, 55 in of precipitation a year, and 7 days a year above 90°F — the loads a replacement here is bought to survive.
The dominant stressor is sustained moisture load. Marietta’s 55 in of annual precipitation sits in the 94th percentile among the 1,037 cities covered here. 55 in a year arriving across roughly 16 days of 1 in-plus rainfall means volume and intensity both. Water finds any lap detailed against the slope, so underlayment coverage, valley metal width, and pipe-boot type matter more in Marietta than in a market where the same total arrives gently.
16 days a year of 1 in-plus rainfall compounds it — in the 89th percentile among the same set. 16 days a year drop an inch or more, and 37 drop at least half an inch. Those are the days that overwhelm an undersized valley or gutter and push water sideways under the course above. Drainage capacity belongs in the Marietta scope conversation, not just shingle grade.

What matters at inspection here
Driven by Marietta’s measured climate
- Valley and penetration detailing. 55 in a year across 16 heavy days finds every lap detailed against the slope. Name valley metal width and pipe-boot type in the scope.
- Deck condition and fastener holding. With no single climate hazard dominating in Marietta, sheathing that will not hold a nail is the most likely reason a scope changes mid-job.

Most full tear-offs require a permit and at least one inspection, handled by City of Marietta Building Department. Budget $235–$625 for permit and inspection fees. Get it in writing that the permit is pulled and the fee sits inside the quote; in Marietta an unpermitted roof tends to surface at a sale or a claim, years later.
Does this guide cover areas near Marietta?
Yes — the closest are Smyrna (5 mi), Kennesaw (6 mi), and Mableton (9 mi), each researched separately. Comparing them is worth a minute: a contractor working out of Smyrna will quote Marietta too, and the two markets do not always price the same.
