For many 2,000 square foot homes in Marietta, a full architectural shingle roof replacement often lands around $12,000 to $22,000, but the roof area, pitch, access, decking, and ventilation matter more than the home's interior square footage.
A 2,000 square foot house is not always a 2,000 square foot roof
The biggest pricing mistake is using the home's living space as the roof size. A 2,000 square foot ranch with a simple gable roof may have a very different roof area than a 2,000 square foot two-story home with valleys, dormers, porches, and a steeper pitch.
In Marietta and Cobb County, many homes in this size range price higher when the roof is steep, access is tight, old shingles need full tear-off, or the decking has soft spots that must be replaced before new shingles go on.
What should be included in the number
- Full tear-off down to the deck, not a roof-over.
- Synthetic underlayment, drip edge, starter strip, ridge cap, and proper flashing details.
- Ice and water shield in valleys and other leak-prone areas.
- Ventilation review so the new roof can actually last.
- Cleanup, magnetic nail sweep, permit handling when required, and written warranty terms.
Why quotes for the same house can be far apart
One quote may include decking allowance, better ventilation, upgraded shingles, and a written workmanship warranty. Another may only price shingles and labor. That is why the cheapest quote is not automatically the best quote.
Ask each roofer to put the material, scope, warranty, and exclusions in writing. If two bids are thousands apart, compare the scope line by line before choosing.
