Roof replacement cost by size
A 1,800 square foot roof with standard asphalt shingles typically costs $9,000 to $14,500 in Marietta, while a larger 2,800 square foot roof common in East Cobb runs $13,500 to $18,500. These figures include tear-off, disposal, new underlayment, and standard architectural shingles.
Homes with steep pitches or multiple dormers, common in Kennesaw Mountain and Sprayberry, run toward the top of these ranges because of added labor time and safety requirements.
What drives the price of a full roof replacement
Material choice is the largest lever. Standard architectural shingles cost less than premium designer shingles, and standing-seam metal roofs, increasingly popular in Indian Hills and Oakton, run $18,000 to $32,000 but last significantly longer. Roof complexity, including valleys, skylights, and chimneys, also adds labor cost beyond the base square footage price.
Decking condition matters too. Older homes near Church Street sometimes need partial or full decking replacement discovered only after tear-off begins, which can add several thousand dollars to the original estimate.
Timing replacement around Cobb County storms
Many Marietta homeowners replace roofs reactively after storm damage rather than proactively, since Cobb County sees regular hail and wind events tracked by NWS Peachtree City from spring through late summer. Scheduling a proactive replacement in late fall or winter, when contractor calendars are lighter, can sometimes secure better pricing and faster turnaround.
Permits and inspections for full replacement
A full re-roof requires a permit from City of Marietta Development Services within city limits, or Cobb County Community Development for unincorporated addresses, typically costing $75 to $250. A final inspection confirms proper underlayment, ventilation, and flashing before the permit closes.
Choosing a contractor for a large investment
Because replacement is a major expense, get at least three written estimates, confirm license status where applicable through the Georgia State Licensing Board for Residential and General Contractors, and ask for manufacturer warranty documentation. See our guide to hiring roofers in Marietta for a full vetting checklist.
