Metal roofing has become a common upgrade for Alpharetta homeowners who want a roof that outlasts asphalt shingles and handles Georgia's heat, storms, and pollen season without curling or granule loss. The category covers standing seam panels, stone-coated steel shingles, corrugated metal, and metal shingle systems, along with the tear-off, decking repair, underlayment, flashing, and ventilation work that goes into a proper install. We've gathered 50 contractors in the Alpharetta area who install or repair metal roofs, from full residential re-roofs to metal accents over porches and dormers.
Before hiring, ask about the panel gauge and coating warranty, whether the crew uses concealed fasteners (standing seam) or exposed screws, and how they handle flashing around chimneys, valleys, and skylights, since that's where most leaks start. Get a written estimate that breaks out material, labor, and any decking repair, and confirm the contractor is licensed and insured and pulls permits with the city or county. Ask how many metal roofs they've installed in the past year versus asphalt, since technique and tooling differ.
Our scoring weighs review volume and recency, rating consistency across platforms, how contractors respond to negative feedback, and verifiable business details like licensing and years active. It's meant to surface installers who do consistent, well-documented work rather than just the ones with the loudest marketing.
