A roof replacement is a major investment, and vague estimates can make planning harder than it needs to be. If you’re looking into a roof replacement in Dallas, GA, or comparing roofing contractors in Marietta, Acworth, or Kennesaw, a realistic budget starts with the size and details of your actual roof, not just your home’s square footage.

For 2026, a straightforward Cobb County replacement using architectural shingles may fall around $8,500–$13,000 for a roof with about 2,000 square feet of surface area. A standing-seam metal roof of a similar size may run roughly $16,000–$30,000. These are typical Atlanta-area planning ranges, not a quote from New Image Roofs. Your measured roof, material selection, and project scope will determine the actual price.

2026 roof replacement cost ranges by roof size and material

Roofing is commonly measured in “squares.” One roofing square equals 100 square feet of roof surface. That is different from your home’s interior square footage: pitch, overhangs, and roof shape all affect the amount of material and labor required.

The table below uses approximate roof surface area, not living area. It provides broad planning ranges for typical full replacements in the Cobb and greater Atlanta area.

These ranges are estimates, not guaranteed project prices. Local cost guides can differ because they make different assumptions about roof area, product grade, tear-off, permits, and other included work. For context, see the 2026 Atlanta cost overview and the Cobb County roof replacement guide.

Architectural shingles are a common choice for their balance of appearance, durability, and cost. Standing-seam metal typically costs more upfront; the exact premium depends on the system, trim, and roof design. Exposed-fastener metal is another option, but it is not the same product or price point as standing seam. Ask for the specific roofing system and materials by name when comparing estimates.

What goes into a roof replacement estimate?

A complete estimate should explain what is included, not just show a total. These are common parts of the job:

• Tear-off and disposal: Removing old roofing, hauling debris, and disposing of it. Multiple existing layers can add labor and disposal costs.
• Underlayment and water protection: Materials installed beneath the roof covering to help protect the home from water intrusion. The proposal should specify the products and where they will be used.
• Shingles or metal panels: Product line, style, color, accessories, and the amount required for the measured roof.
• Flashing and roof details: Metal or compatible materials around chimneys, walls, valleys, and other roof transitions. Reusing worn flashing may lower an estimate initially, but it may not be the right long-term solution.
• Decking repairs: Damaged or deteriorated roof sheathing may need replacement once the old roof is removed. Ask how additional decking is priced and how the contractor will get your approval before doing extra work.
• Installation labor and cleanup: Crew labor, site protection, magnetic nail cleanup, and final inspection.
• Permits and project logistics: Requirements vary by project and jurisdiction. Confirm whether applicable permits, dumpster or disposal costs, and other project costs are included.

A contractor should explain what is known before work begins and how any concealed damage will be handled. That helps you avoid surprises when the roof is opened.

What can move the price up or down?

The roof’s surface area is only one factor. A simple, accessible roof will generally cost less to replace than a steep roof with multiple sections and detailed features.

• Pitch and stories: Steeper roofs and taller homes require additional safety measures and can take longer to work on.
• Roof complexity: Dormers, valleys, skylights, chimneys, and multiple rooflines call for more careful cutting and flashing work.
• Existing layers and condition: Removing additional roofing layers or replacing deteriorated decking can increase the scope. Decking costs should be listed clearly, often as a per-sheet amount or an allowance.
• Material and accessories: Premium shingle lines, metal profiles, ventilation components, and upgraded flashing can affect the total.
• Access and site setup: Limited driveway access, landscaping, and the location of the home can affect how crews protect the property and move materials.

If a price seems unusually low, check whether it leaves out important items. A bid that excludes tear-off or assumes existing flashing can be reused may not be comparable to one that includes a complete replacement scope.

How to compare roofing quotes fairly

When evaluating roofing companies in Cobb County, GA, compare written scopes, not just bottom-line numbers. Each proposal should identify the measured roof area, roofing product, underlayment, tear-off and disposal, flashing work, ventilation details, cleanup, warranty coverage, and permit responsibility.

Ask these practical questions:

1. How many roofing squares did you measure, and what roof features or waste allowance are included?
2. Does the price include removing all existing roofing layers?
3. How will you document and price decking repairs if they are needed?
4. Which flashing and ventilation work is included?
5. What workmanship and manufacturer warranties apply?
6. Who will manage permits and cleanup?

Financing and insurance: what to keep in mind

If you’re planning a replacement as a home improvement, ask contractors or your lender about available payment or financing options, and review the terms carefully. Don’t assume a low monthly payment represents the full project cost.

If a storm damaged your roof, contact your insurer and review your policy, deductible, and claim requirements. Coverage depends on your policy and the facts of the loss; no contractor can guarantee an insurer will approve a claim. A roofing professional may help document visible conditions, but the insurer makes coverage decisions.

FAQs about roof replacement costs in Cobb County

How much does a typical roof replacement cost in Cobb County in 2026?

For a roof with about 2,000 square feet of surface area, a broad planning range is approximately $8,500–$13,000 for architectural shingles and $16,000–$30,000 for standing-seam metal. A measured inspection is needed for an accurate estimate.

Is roof size the same as my home’s square footage?

No. Home square footage usually describes interior living area. Roof area changes with pitch, overhangs, and design. Ask contractors to provide the measured roof area used for their proposal.

Can a roof be repaired instead of replaced?

Often, yes. A leak or limited storm damage does not automatically mean you need a new roof. An honest inspection should explain whether a repair is practical or whether age, widespread damage, or roof condition makes replacement the better option. Learn about roof repair services.

Does homeowners insurance pay for a roof replacement?

It may cover eligible damage, depending on your policy and the cause of the damage. The insurer decides coverage and payment. Review your policy and deductible before making plans.
