Metal Roofing Calculator | Panels, Cost & Materials Instantly
Replacing or installing a metal roof is one of the biggest investments a homeowner makes — yet most people have no idea how much material they actually need until they’re standing at the lumber yard, second-guessing every measurement. Miscalculate by even 10%, and you’re either making costly emergency runs mid-project or paying for panels that sit unused in your garage. That’s where our Metal Roofing Calculator comes in. Enter your roof dimensions, pitch, and panel type, and get an instant, accurate breakdown of panels, ridge cap, trim, fasteners, and total material cost — so you can order with confidence the first time.
Enter 0 for a flat roof. Common pitches: 3:12 (low), 6:12 (medium), 12:12 (steep).
Standard panels come in 8 ft, 10 ft, 12 ft, 16 ft, and 20 ft lengths.
* Estimates only — costs vary by gauge, coating, region, and installer. Does not include underlayment, fasteners, trim, or installation labour.
