Roof replacement means stripping the existing roof covering down to the deck and installing a new system: underlayment, flashing, ventilation, and a new surface layer (asphalt shingle, metal, tile, or a flat roofing membrane depending on the building). It's a different job from a repair or a re-roof over old shingles. A full tear-off lets a crew catch rotten decking, damaged flashing around chimneys and vents, and ventilation problems that a patch job would leave in place. In metro Atlanta, that matters because of the mix of older wood-decked homes, heavy summer thunderstorms, and the occasional hailstorm that pushes an insurance claim into the mix. We've listed 147 roof replacement businesses serving the Atlanta area, ranging from small local crews to larger regional companies.
Before you hire, look past the sales pitch and check a few concrete things: a Georgia-licensed and insured business (general liability and workers' comp, since roofing has a high injury rate), a written estimate that spells out tear-off, decking repair pricing, underlayment type, flashing, and ventilation (not just "shingles"), manufacturer certification if you want a strong material warranty, and local references or job photos you can actually verify. Get more than one quote. A wide spread in price usually means the bids aren't scoped the same way, so ask each contractor to itemize.
Our scoring weighs licensing and insurance status, review volume and rating consistency over time, responsiveness, and how complete a contractor's public information is, so you're not starting from zero when you compare 147 options.
