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
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
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
