TL;DR: Roof replacement in Marietta, GA typically costs between $8,000 and $18,000 for a standard single-family home, depending on roof size, materials, and local labor rates. Cobb County permits add $75–$200, and architectural shingles (the most popular choice here) run $5.50–$7.00 per square foot installed. We'll walk you through the cost breakdown, material options, and what to expect when getting estimates.
How Much Does Roof Replacement Cost in Marietta, GA?
The average roof replacement cost in Marietta, GA ranges from $8,000 to $18,000 for a typical single-family home. This figure reflects the Atlanta metro area's elevated labor demand and the specific conditions homeowners face here in Cobb County.
To understand your likely cost, start with your roof size. A 1,500–1,900 square foot roof typically runs $8,500–$12,500, while a 2,000–2,400 square foot roof falls in the $9,000–$18,000 range. Larger homes (2,500–3,000 sq ft) often see costs between $12,000 and $22,000.
The installed cost per square foot generally falls between $4.50 and $9.00, depending on the material you choose. This is higher than national averages, primarily because Cobb County contractors face strong seasonal demand (especially March through July) and the labor market here reflects metro Atlanta's pricing structure.
Here's a quick reference for typical Marietta home sizes:
| Roof Size (sq ft) | Estimated Cost Range |
|---|---|
| 1,500–1,900 | $8,500–$12,500 |
| 2,000–2,400 | $9,000–$18,000 |
| 2,500–3,000 | $12,000–$22,000 |
| 3,100+ | $15,000–$28,000+ |
These ranges assume standard asphalt or architectural shingles with one layer of tear-off. Steeper roof pitches, additional layers, decking damage, or premium materials will push costs higher. We'll break down each factor below.
Key Takeaway: For a typical 2,000 sq ft Marietta home with architectural shingles, expect a base cost around $12,000–$14,000 before permits and any structural repairs.
What Factors Affect Your Roof Replacement Cost?
Several variables move your final quote up or down. Understanding each one helps you anticipate what a contractor will charge and identify where you might have flexibility.
Roof Size and Pitch Larger roofs cost more simply because they require more material and labor. But pitch (steepness) matters just as much. A standard 6/12 pitch is straightforward; a steep 10/12 or 12/12 pitch adds 20–30% to labor costs, as roofing contractors explain, because contractors need additional safety equipment and work more slowly. On a 2,000 sq ft Marietta home, that steep-pitch premium could add $2,500 or more.
Tear-Off Layers Removing an existing shingle layer costs $1.00–$1.50 per square foot. If your roof has two layers (common in older Marietta homes), you're looking at $2.00–$3.00 per square foot just for removal. Georgia building code generally prohibits more than two layers, so homes with three layers require a full tear-to-deck, which increases labor time and disposal costs.
Decking Damage and Rot Once the old shingles come off, inspectors often find damaged or rotted plywood underneath. Replacing a 4×8 sheet of decking typically costs $75–$150 per sheet, including labor. A roof with widespread rot can add $1,500–$5,000 to your project.
Chimneys, Skylights, and Valleys Every penetration and valley requires careful flashing work. A single chimney or skylight adds complexity and material cost. Multiple penetrations or complex roof geometry can add $500–$2,000 to your estimate.
Attic Ventilation Requirements Georgia's building code (based on the International Residential Code) requires 1 square foot of net free ventilation per 150 square feet of attic floor space. Pre-1990 Marietta homes often lack adequate ventilation, and inspectors will flag this during permit review. Adding or upgrading ventilation can cost $500–$2,500 depending on your attic configuration.
Seasonal Demand Metro Atlanta roofing contractors carry 4–8 week backlogs from March through July, with demand premiums of 10–15% during peak season. November through February offers genuine negotiating leverage and faster scheduling.
Permit and Inspection Fees The City of Marietta and unincorporated Cobb County both require roofing permits. Expect $75–$200 in permit fees, depending on your project valuation and jurisdiction.
Roofing Material Costs: Which Option Fits Your Budget?
Material choice is the single biggest lever you control. Here's what each option costs installed in the Marietta market, along with lifespan and best-use scenarios.
| Material | Cost/sq ft (Installed) | Lifespan | Best For |
|---|---|---|---|
| 3-Tab Asphalt | $4.50–$5.50 | 15–20 years | Budget-conscious homeowners; rental properties |
| Architectural Shingles | $5.50–$7.00 | 20–30 years | Most Marietta homes; balance of cost and durability |
| Metal Roofing | $9.00–$15.00 | 40–70 years | Long-term investment; energy efficiency; modern aesthetics |
| Tile/Slate | $12.00–$20.00+ | 50+ years | Premium custom homes; specific architectural styles |
Asphalt Shingles (3-Tab) The cheapest option at $4.50–$5.50 per square foot installed. A 2,000 sq ft roof would cost roughly $9,000–$11,000 in materials and labor. These shingles are durable enough for Georgia's climate but typically last 15–20 years before needing replacement.
Architectural (Dimensional) Shingles The most popular choice in Marietta at $5.50–$7.00 per square foot installed. For a 2,000 sq ft roof, expect $11,000–$14,000. Architectural shingles have a layered, dimensional appearance that looks more upscale than 3-tab, and they last 20–30 years. This is the sweet spot for most homeowners balancing cost and longevity.
Impact-Resistant Shingles (Class 4) These cost $1,500–$3,000 more than standard architectural shingles on a typical Marietta roof, but they unlock Georgia insurance discounts of 20–28%. If your insurer offers this discount, the premium often pays for itself within 3–5 years. Class 4 shingles are tested to withstand hail impact and are increasingly common in Cobb County, which averages 4+ significant hail events annually.
Metal Roofing Standing-seam metal roofing runs $9.00–$15.00 per square foot installed. A 2,000 sq ft roof costs $18,000–$30,000. Metal roofs last 40–70 years, require minimal maintenance, and offer excellent energy efficiency. They're gaining popularity in Marietta for new construction and high-end renovations, though the upfront cost is substantial.
Tile and Slate Rare in standard Marietta residential but common in premium East Cobb custom builds. Costs range $12.00–$20.00+ per square foot installed. These materials are beautiful, extremely durable (50+ years), but require specialized labor and structural reinforcement due to weight.
Transparent Calculation Example: A 2,000 sq ft Marietta home with architectural shingles:
- Material + labor: 2,000 sq ft × $6.00/sq ft = $12,000
- One layer tear-off: 2,000 sq ft × $1.25/sq ft = $2,500
- Permit (City of Marietta): $150
- Total estimate: $14,650
This assumes standard pitch, no decking damage, and no additional complexity. Steeper pitch, rot, or ventilation upgrades would add to this figure.

Cobb County Permits and Local Requirements: What Will It Cost?
Here in Marietta, Georgia, understanding your permitting jurisdiction is critical - and it's a detail most national guides miss.
City of Marietta vs. Unincorporated Cobb County If your address is within the City of Marietta limits, you pull permits through the City of Marietta Development Services. If you're in unincorporated Cobb County, you work with Cobb County Community Development. This distinction matters because each jurisdiction has its own fee schedule and inspection process.
Permit Costs Residential roofing permits in both jurisdictions typically cost $75–$200, depending on your project valuation. The fee is calculated as a percentage of the estimated project cost, so a $14,000 roof replacement might generate a $150 permit fee. Always verify the current fee schedule with your local jurisdiction before budgeting.
When a Permit Is Required A full roof replacement always requires a permit in Cobb County and the City of Marietta. Repairs (patching, flashing work) may not require a permit if they're minor, but a licensed contractor will advise you on this. Never skip the permit to save money - unpermitted work can void your homeowner's insurance claim and create title issues at resale.
HOA Considerations Many Marietta neighborhoods, especially in East Cobb, have HOAs with specific roofing material and color requirements. Your HOA may mandate certain shingle brands, colors, or types. Check your CC&Rs before selecting materials; some HOAs restrict metal roofing or require architectural shingles in specific colors. This can limit your material choices and sometimes increase costs if your preferred option isn't approved.
Licensed Contractor Requirement Only a licensed Georgia roofing contractor can legally pull a permit in Cobb County or Marietta. If a contractor asks you to pull the permit yourself, that's a red flag - they likely aren't licensed. Always verify your contractor's license through the Georgia Secretary of State's online verification portal before signing any agreement.
Does Homeowners Insurance Cover Roof Replacement in Marietta?
Insurance claims are the most common trigger for roof replacement in Cobb County, which sits in the hail-prone "Dixie Alley" corridor. Understanding what your policy covers - and what it doesn't - is essential to calculating your actual out-of-pocket cost.
Hail and Wind Damage in Cobb County Cobb County averages 4+ significant hail events annually. When a storm damages your roof, your homeowners insurance may cover the replacement cost, but the payout depends on your policy type and the age of your roof.
ACV vs. RCV Policies This distinction is the single largest variable in what you'll actually pay. An ACV (Actual Cash Value) policy reimburses you based on the roof's depreciated value. A 10-year-old roof might be depreciated 50% or more, leaving you to cover the balance out of pocket. An RCV (Replacement Cost Value) policy reimburses the full cost of replacement without depreciation. RCV policies cost more but are far more valuable after a claim. Check your policy documents to see which type you have.
Deductibles and Wind/Hail Deductibles Standard deductibles range $1,000–$2,500. Many Georgia policies also carry separate wind or hail deductibles of 1–2% of your dwelling coverage. On a $300,000 home, a 1% wind deductible equals $3,000 - significantly higher than your standard deductible. You'll pay whichever is higher when filing a claim.
Steps to File a Roof Claim
- Document damage with photos and video immediately after a storm.
- Contact your insurer promptly (check your policy for required timeframe).
- Schedule an adjuster inspection.
- Obtain a contractor estimate for the scope of work.
- File a supplemental claim if the adjuster's scope differs from the contractor's estimate.
Out-of-Pocket Cost Scenario Suppose your roof replacement costs $14,000. You have an ACV policy with a $1,500 deductible. Your 10-year-old roof is depreciated 40%, so the insurer pays $8,400 (60% of $14,000). You pay the $1,500 deductible plus $5,100 out of pocket - a total of $6,600. With an RCV policy, the insurer would pay $14,000 minus your $1,500 deductible, leaving you to pay only $1,500.
Important Legal Note Georgia law (O.C.G.A. § 33-32-1) prohibits roofing contractors from waiving, absorbing, or rebating your insurance deductible as an inducement to hire them. If a contractor offers to "cover your deductible," they're committing insurance fraud. Legitimate contractors will work with your insurer on the scope of loss but won't illegally waive your deductible.
How to Get an Accurate Roof Replacement Estimate in Marietta
Ready to move forward? Here's how to get reliable quotes and avoid low-ball estimates that hide costs.
Step 1: Measure Your Roof You don't need to climb onto your roof yourself. A contractor will measure it during the site visit. But knowing your approximate square footage helps you compare quotes. If you know your home's footprint, multiply by 1.2–1.4 to account for pitch and overhangs - that's a rough estimate of roof area.
Step 2: Get Three Quotes Always request estimates from at least three licensed contractors. This gives you a range and helps you spot outliers. Compare apples to apples: each quote should include a line-item breakdown of materials, labor, tear-off, permits, and any structural repairs.
Step 3: Verify Licensing and Insurance Before signing anything, verify your contractor's Georgia State Contractor License at the Secretary of State's online portal. Confirm they carry general liability and workers' compensation insurance. Ask for certificates of insurance; a legitimate contractor will provide them without hesitation.
Step 4: Red Flags in Low-Ball Estimates If a quote is significantly lower than others, ask why. Common red flags include:
- No line-item breakdown (vague "labor" charges)
- No mention of permits or inspection
- Pressure to sign immediately
- Contractor asks you to pull the permit
- No written warranty or guarantee
Step 5: Compare Warranties Material warranties (from the shingle manufacturer) typically cover defects for 20–30 years. Workmanship warranties (from the contractor) vary widely - some offer 5 years, others 10 or more. A longer workmanship warranty reflects contractor confidence and is worth paying slightly more for.
Professional Edge Roofing provides detailed, line-item estimates with transparent pricing and full warranty coverage. When you request an estimate, you'll receive a clear breakdown of all costs - materials, labor, permits, and any repairs - so there are no surprises at project completion.

Frequently Asked Questions About Marietta Roof Replacement Costs
What is the average cost to replace a roof in Marietta, GA in 2026?
Direct Answer: The average roof replacement in Marietta, GA costs $8,000–$18,000 for a typical single-family home, with most projects averaging around $12,000–$14,000 for a 2,000 sq ft roof with architectural shingles.
For a precise estimate, you'll need to account for your specific roof size, pitch, material choice, and any structural repairs. Architectural shingles (the most popular option here) run $5.50–$7.00 per square foot installed, while asphalt 3-tab shingles cost $4.50–$5.50 per square foot. Cobb County permits add $75–$200 to your total.
How long does a roof replacement take in Marietta?
Direct Answer: A typical roof replacement in Marietta takes 1–3 days, depending on roof size, complexity, and weather.
A standard 2,000 sq ft roof with straightforward pitch usually takes 1–2 days. Steeper pitches, multiple penetrations (chimneys, skylights), or decking repairs can extend the timeline to 3–5 days. Weather delays are common in Georgia's rainy season (June–August), so scheduling in fall or spring often means faster completion.
Is a permit required for roof replacement in Cobb County?
Direct Answer: Yes, a building permit is required for any full roof replacement in both the City of Marietta and unincorporated Cobb County.
Permits ensure your work meets local building codes and protects your homeowner's insurance coverage. Unpermitted work can void insurance claims and create title issues at resale. Only a licensed Georgia contractor can legally pull a permit. Permit costs typically range $75–$200 depending on your project valuation.
Does homeowners insurance pay for roof replacement after a hail storm in Georgia?
Direct Answer: Yes, homeowners insurance typically covers hail damage to your roof, but the payout depends on your policy type (ACV vs. RCV), the age of your roof, and your deductible.
An ACV (Actual Cash Value) policy reimburses based on depreciated value, often leaving you to cover 30–50% out of pocket. An RCV (Replacement Cost Value) policy covers the full replacement cost without depreciation. Deductibles typically range $1,000–$2,500, with some policies carrying separate wind/hail deductibles of 1–2% of dwelling value. File a claim promptly after storm damage and request a written scope of loss from the adjuster before hiring a contractor.
How does Marietta roof replacement cost compare to other Atlanta suburbs?
Direct Answer: Marietta's roof replacement costs are comparable to other East Cobb and Atlanta metro suburbs like Kennesaw and Smyrna, typically ranging $8,000–$18,000 for a standard home.
Labor rates across the Atlanta metro are fairly consistent, so your cost in Marietta will be similar to nearby areas. The main variables are your specific roof size, pitch, material choice, and local labor availability. Seasonal demand (March–July) affects pricing across the entire metro area, so timing your project for fall or winter can save 10–15%.
What is the cheapest roofing material for a Georgia home?
Direct Answer: 3-tab asphalt shingles are the cheapest option at $4.50–$5.50 per square foot installed, costing roughly $9,000–$11,000 for a 2,000 sq ft roof.
However, architectural shingles at $5.50–$7.00 per square foot offer better durability (20–30 years vs. 15–20 years) and are only $1,500–$3,000 more on a typical Marietta home. For most homeowners, architectural shingles provide better long-term value. If you're in a hail-prone area like Cobb County, Class 4 impact-resistant shingles cost $1,500–$3,000 more but unlock insurance discounts of 20–28%, often paying for themselves within 3–5 years.
How do I know if I need a full roof replacement or just repairs?
Direct Answer: If your roof is over 20 years old, has widespread damage (more than 30% of the surface), or requires frequent repairs, replacement is usually more cost-effective than repair.
A contractor can inspect your roof and advise whether repair or replacement makes sense. Minor damage (a few missing shingles, isolated leaks) can be repaired for $300–$1,000. But if you're facing multiple repairs or your roof is nearing the end of its lifespan, replacement typically costs less over time and provides better peace of mind.
