What affects the cost of a roof in Alpharetta
Two Alpharetta homes the same size can land thousands apart on price. A few things move the number more than anything else:
- Roof size and pitch. Roofers price by the "square" (100 sq ft of roof). The steep, multi-gable rooflines common on Windward and Avalon-area homes cost more to stage and install than a low ranch roof off Rucker Road.
- Material. Architectural shingles are the North Fulton default, and many HOAs out here require them. 3-tab is cheaper but shorter-lived; designer shingles and standing-seam metal cost more up front and last decades longer.
- Tear-off and decking. Pulling old layers and swapping rotted decking adds labor and material. On 1990s and early-2000s subdivision homes near Webb Bridge and Old Milton, that decking work shows up more often than owners expect.
- Storm and insurance work. When hail or wind off the GA-400 corridor causes the damage, insurance may cover most of a full replacement, so your out-of-pocket can be just the deductible.
