Metal roof calculator. panels, screws, trim, and cost for standing seam and corrugated metal roofing.
Enter roof footprint, pitch, and material type.
Metal roofing has surged in popularity for residential use — it lasts 40–70 years (vs. 20–30 for asphalt shingles), reflects heat to reduce cooling costs, and handles severe weather better than nearly any other roofing material. The tradeoff is upfront cost: metal roofing runs 2–3× the price of asphalt shingles installed. This calculator estimates panel count, screws, ridge cap, and trim for both corrugated and standing seam metal roofing.
Divide your total roof area (including pitch multiplier and waste) by the coverage area per panel. A standard 36-inch-wide panel that's 20 feet long covers 60 sq ft. A 2,000 sq ft roof needs about 37 panels at that size, plus ridge cap, eave trim, and gable trim.
Material cost ranges from $3–$8 per sq ft for corrugated panels to $8–$14 per sq ft for standing seam. Installed cost runs $7–$15 per sq ft total. A 2,000 sq ft roof: $14,000–$30,000 installed. Compare that to asphalt shingles at $6,000–$12,000 — but the metal roof will last 2–3× longer.
Metal roofing is a long-term investment — the higher upfront cost is offset by 40–70 year lifespan, lower maintenance, better energy efficiency, and higher home resale value. Whether corrugated or standing seam, accurate panel estimation starts with your roof footprint and pitch. This calculator handles the pitch multiplier and returns panel count, trim, and fasteners.
