Corrugated Roofing: Plastic vs Metal

The differences between plastic and metal corrugated roofing range from slightly to extremely different. And yet, each has its positives and negatives when you are considering what you would like to use for your roof.


  • Plastic does not handle extreme heat very well
  • Plastic tends to occasionally chip when metal will not as easily
  • Will provide natural lighting for indoors
  • If damaged during installation or in extreme weather a chip or crack can spread to ruin the entire panel
  • Plastic has more aesthetic appeal than metal
  • Typically more expensive than metal
  • Sometimes needs a special kind of paint if you want to paint the plastic panels
  • Not as flimsy as metal and the weight is usually better for extreme weather
  • Commonly more water-tight than metal


  • Commonly quite cheap and affordable
  • Is wholly more durable than plastic
  • Constructing a roof with corrugated metal is difficult to work with in windy weather because  it is light-weight
  • Will have to be treated for rust
  • Can dent in extreme weather
  • Only a small crew needed when working with metal corrugated roofing
  • Can be painted very easily
  • Commonly rigid and flimsy
  • Nosier than plastic in extreme weather like hard rain or hail.
  • A false ceiling will need to be installed if you do not want the heat that the metal absorbs to radiate inside
