A properly installed metal roof shrugs off the sun, humidity, and storm seasons that age an asphalt roof out early. It costs more up front and then stops costing you anything for decades.
The same climate that shortens an asphalt roof's life is what metal is built for. Summer sun that dries out and curls shingles reflects off a metal panel. Storm-season wind that peels shingle tabs has no loose edge to grab on a standing seam roof. And the algae streaking that shows up on north-facing asphalt slopes across Knoxville simply doesn't take hold on metal.
As a ballpark, 2026 national cost guides (Angi, HomeGuide) put metal roofing at roughly $7 – $14 per square foot installed, with whole-home projects commonly landing in the $7,500 – $40,000 range depending on the metal, panel profile, and gauge. That is a market range, not a quote, and it is exactly why the estimate starts with someone looking at your roof for free. If the up-front number is the obstacle, financing available.
