R panel roofing is typically 36 inches wide, which makes it one of the most common metal roofing options for homes and buildings. Each panel covers a large area quickly, so contractors can finish jobs faster. R panels are popular because they cost less than other metal roof types and last a very long time. According to RubyHome, metal roofing costs between $10.00 and $17.05 per square foot with installation included. Understanding the width of R panels helps you know how many panels you need for your roof.

What Size Is an R Panel?

R panels measure 36 inches wide from edge to edge. The actual coverage width is usually 34 inches because there is a 1-inch overlap on each side where panels connect.

This overlap keeps water from getting between panels. Most R panels come in lengths from 8 feet to 40 feet, depending on what you need.
