Metal roofing has become a common upgrade around McDonough, especially on homes replacing worn-out three-tab shingles or barns and outbuildings that need something that will outlast a couple of shingle cycles. This category page covers 15 local contractors who install and repair metal roofing, from standing seam panels to exposed-fastener systems and metal shingles.
What metal roofing work involves
A metal roof job usually starts with tearing off the old roofing (or installing over existing shingles if the deck allows it), checking and repairing the decking, adding synthetic underlayment and ice-and-water barrier at eaves and valleys, then installing panels with either hidden clips (standing seam) or exposed screws. Flashing at chimneys, vents, skylights, and roof-to-wall transitions is where most leaks originate, so how a crew handles those details matters more than the panel brand. Ridge caps, trim, and proper ventilation finish the job. Repairs range from resealing fastener heads and replacing a damaged panel to fixing flashing that has pulled loose in a storm.
What to look for before hiring
- Licensing and insurance: confirm current general liability and workers' comp coverage, since roof work carries real injury risk.
- Manufacturer certification: installers certified by panel manufacturers (like those offering 40-year finish warranties) tend to follow spec more consistently.
- Written estimates: a detailed quote should break out panel gauge and finish, underlayment type, flashing work, and tear-off/disposal, not just a single lump sum.
- Local storm experience: Georgia's hail and wind events mean a crew that has handled insurance claims in this area will know how to document damage and work with adjusters.
- Warranty terms: separate the paint/finish warranty from the workmanship warranty, and get both in writing.
