Metal Roofing Panel Calculator

How It Works

Metal roofing panels come in three main styles. Standing seam panels have raised seams that interlock, offering superior weather resistance — they typically cover 12-18 inches of width. Corrugated panels have a wavy profile covering about 24 inches. R-panel (ribbed) panels cover 36 inches and are the most economical. Metal roofs last 40-70 years, reflect heat to lower cooling costs, and are 100% recyclable. Panels are cut to your exact rafter length, so waste is typically just 3-5%. Use 80 screws per 100 sq ft with neoprene washers to prevent leaks.
