Roof replacement is different from a repair: instead of patching a leak or swapping a few shingles, the crew strips the old roofing material down to the deck, checks the decking for rot or soft spots, replaces damaged plywood, installs new underlayment and flashing, and lays a full new roof covering. In Cumming, most homes run asphalt shingles, though you'll also find metal roofs on newer builds and some architectural shingle upgrades on older subdivisions around Forsyth County. A full tear-off and replacement on an average house typically takes two to five days, depending on roof size, pitch, and whether the crew hits any decking surprises once the old shingles come off.
With 33 roof replacement contractors serving the Cumming area, the range in price, workmanship, and reliability is wide. A buyer should look for a few concrete things before signing a contract: proof of Georgia licensing and insurance (general liability and workers' comp), a written estimate that breaks out tear-off, decking repair, underlayment, and shingle costs separately, a manufacturer certification if you want a stronger warranty (like GAF Master Elite or CertainTeed SELECT ShingleMaster), and a clear plan for cleanup and magnetic nail sweeps. It also helps to ask how they handle decking replacement pricing, since that's the most common source of change-order disputes after the job starts.
