Replacing a roof in Marietta typically costs $8,000–$25,000 in 2026, depending on roof size, material, pitch, tear-off requirements, and structural repairs. For a roof area of 2,000–2,500 square feet, a standard architectural shingle replacement commonly falls between $8,100 and $18,950 before unusual decking repairs or major upgrades.
Metro Atlanta labor rates are running about $75–$95 per hour, while architectural shingle installations generally fall within the regional range of approximately $405–$758 per square. One roofing square equals 100 square feet of roof area.
The tables below provide a practical Marietta budget range before you request contractor bids.
2026 Roof Replacement Cost in Marietta by Material
These estimates assume a standard residential roof, normal access, one existing layer, and no major structural damage. The low-middle-high ranges include typical installation labor and materials.
| Roofing material | Cost per square | 2,000 sq. ft. roof (20 squares) | 2,500 sq. ft. roof (25 squares) |
|---|---|---|---|
| 3-tab asphalt shingles (Budget) | $350–$550 | $7,000–$11,000 | $8,750–$13,750 |
| Architectural shingles (Popular) | $405–$758 | $8,100–$15,160 | $10,125–$18,950 |
| Class 4 impact-rated shingles (Storm upgrade) | $500–$900 | $10,000–$18,000 | $12,500–$22,500 |
| Standing-seam metal (Premium) | $900–$1,700 | $18,000–$34,000 | $22,500–$42,500 |
| Synthetic/composite roofing (Premium) | $700–$1,400 | $14,000–$28,000 | $17,500–$35,000 |
A typical Marietta home with a straightforward architectural shingle roof often lands near $10,000–$16,000. Complex roofs, multiple tear-off layers, premium warranties, and extensive decking replacement can push the total higher.

Material Comparison for Marietta Homeowners
3-Tab Asphalt Shingles (Budget)
Three-tab shingles offer the lowest initial price. They are appropriate for homeowners prioritizing basic weather protection and a lower upfront budget.
However, they generally provide less dimensional appeal and fewer premium warranty options than architectural products. In Marietta’s hail and wind environment, compare the manufacturer’s wind rating and warranty before choosing this option.
Architectural Shingles (Popular)
Architectural shingles are the most common replacement choice in metro Atlanta. They provide better curb appeal, thicker construction, and more design options than three-tab shingles.
The regional installed range is approximately $405–$758 per square, with the final price driven by roof complexity, shingle brand, ventilation, flashing, and tear-off work.
Class 4 Impact-Rated Shingles (Storm Upgrade)
Class 4 shingles are designed to resist impact better than standard asphalt products. They are worth considering in Cobb County because hail and severe thunderstorms are most common from spring through late summer.
Some insurance carriers offer premium credits for qualifying Class 4 products. Confirm the discount with your insurance company before installation and keep the product documentation, invoice, and final inspection records.
Standing-Seam Metal (Premium)
Standing-seam metal provides long service life, strong wind performance, and a modern appearance. It costs considerably more because of specialized fabrication, installation, trim, flashing, and labor.
Metal can be especially attractive for modern homes or homeowners planning to remain in the property long term. Ask whether the quote includes concealed fasteners, underlayment, closures, ridge ventilation, and proper wall and chimney flashing.
Synthetic or Composite Roofing (Premium)
Synthetic roofing can replicate the appearance of slate, cedar, or other premium materials while weighing less than many traditional products. It typically costs more than asphalt but less than some natural roofing systems.
This option may make sense for homeowners focused on appearance, durability, and resale appeal. Review product warranties carefully because installation requirements vary by manufacturer.
What Changes the Final Roof Replacement Price?
Roof Size and Squares
Contractors price roofing by the square, not by the home’s interior square footage. A 2,000-square-foot house may have more than 2,000 square feet of actual roof area after pitch, overhangs, garages, and porches are measured.
Satellite measurements can provide a useful starting point by calculating roof planes, approximate size, and complexity before an onsite contractor visit.
Pitch and Complexity
A simple gable roof costs less than a steep, multi-plane roof. Additional labor is common for:
- Dormers and skylights
- Valleys and hips
- Multiple roof sections
- Steep pitches
- Difficult access
- Chimneys, plumbing vents, and wall intersections
- Attached garages and additions
A steep or highly cut-up roof may add 10%–30% or more compared with a basic roof of the same measured area.
Tear-Off Layers
Removing old shingles adds disposal, labor, and equipment costs. Two or more existing layers may require additional time and may not be allowed beneath the new system.
As a planning benchmark, tear-off and disposal can add roughly $100 per square or more, depending on the number of layers and local disposal charges.
Decking Repairs
Marietta’s housing stock averages approximately 39 years old, so decking repairs are a common budget consideration. Once shingles are removed, contractors may find water-damaged, soft, or improperly fastened plywood.
Ask for a clear per-sheet price for decking replacement. A quote that says “decking as needed” without a unit price can make the final invoice difficult to predict.
Underlayment, Ventilation, and Flashing
A complete roof system usually includes more than shingles:
- Synthetic underlayment
- Ice-and-water protection at vulnerable areas
- Drip edge
- Ridge and soffit ventilation
- Pipe boots
- Valley metal or membrane
- Chimney and wall flashing
- Ridge caps
Although Marietta does not experience the same ice exposure as northern states, underlayment and water-shedding details remain important during heavy rain and wind-driven storms.
Gutters and Other Add-Ons
Gutters, downspouts, fascia, skylights, and chimney repairs may be separate line items. Mature neighborhoods with large pine and hardwood canopies may also require tree trimming or debris management before installation.
Cobb County and City of Marietta Roof Permit Rules
A building permit is required in 2026 for a re-roof involving removal of existing roofing materials. The correct permitting office depends on whether the property is inside the City of Marietta or in unincorporated Cobb County.
Unincorporated Cobb County
Permits are handled through the Cobb County Community Development Agency.
The reported fee structure includes:
- Permit fee calculated from construction valuation at approximately $6.85 per $1,000
- $50 Letter of Completion fee
- $15 technology fee
The valuation generally includes labor and materials. Confirm the current fee schedule before signing because county fees can change.
City of Marietta
Properties inside city limits use the Marietta Building Division.
Residential re-roof permit charges are valuation-based. Typical fees may range from approximately $235 to $625, depending on project value and the applicable fee schedule. The city may also require contractor documentation, including:
- A current City of Marietta business license
- Proof of general liability insurance
- Workers’ compensation documentation when applicable
- Scope of work and project valuation
Your contractor should identify the permitting jurisdiction and confirm that the permit is pulled before work begins.
Marietta Insurance and Hail-Season Budget Trends
Georgia insurance premiums are projected to rise approximately 10% in 2026, following an estimated 8.6% increase in 2025. Many policies now use percentage-based wind and hail deductibles, often around 1%–2% of dwelling coverage.
For example, a 2% deductible on $400,000 of dwelling coverage equals $8,000 out of pocket. That number may be more important to your storm budget than the roofing estimate itself.
Other trends to review with your insurance agent include:
- Roofs older than 15 years may face greater underwriting scrutiny.
- Some carriers are moving older roofs to actual cash value coverage.
- Class 4 shingles may qualify for premium discounts.
- New roof documentation can affect eligibility and coverage terms.
- Storm claims may receive more detailed inspection during the 2026 season.
The National Weather Service reports that North and Central Georgia experience damaging thunderstorm winds throughout the year, with the greatest frequency during spring and summer. Large hail occurs most often around April but can affect the region through summer. Cobb County’s mature tree canopy adds additional risk from falling branches and pine debris.
Budgeting and Scheduling Tips for 2026
- Measure before collecting bids. Start with the roof’s actual squares, not the home’s living area.
- Request low-middle-high pricing. This shows how material choices and unknown repairs affect the budget.
- Ask for unit prices. Get separate costs for decking, tear-off layers, ventilation, flashing, and gutters.
- Review your insurance first. Confirm your wind/hail deductible and whether the roof is covered at replacement cost or actual cash value.
- Schedule before peak storm demand. Spring and summer storms can increase inspection and contractor demand.
- Get permit responsibility in writing. The contract should state who applies for the permit and schedules inspections.
- Keep a contingency reserve. Set aside at least 10%–15% for decking, flashing, ventilation, or code-related repairs.
