Pros of Plastic Roofing

Polycarbonate panels are made with bisphenol A (BPA), which is a shatter-resistant agent that allows this plastic to have high-performance and remain pliable—thus making it an ideal material for a plastic roof as it is tough and can handle unexpected impacts from the natural surroundings.

The lightweight qualities of polycarbonate roof panels and plastic roofing offer many benefits compared to other alternative materials such as aluminum and glass. One advantageous benefit is more reasonable shipping costs, especially compared to metal—saving time and money. In addition to the savings, installation will be a breeze once contractors experience how easy and effortless polycarbonate plastic roof sheets are easy to handle.

Blocks UV Rays
Another stand out quality that polycarbonate roofing has to offer is its incredible UV blocking capabilities. These plastic roof sheets are an ideal material for constructing awnings, greenhouses, sunroom roofing, and pool covers. According to, “Polycarbonate as a material blocks almost the entire relevant UV spectrum, meaning both UVA and UVB. The material absorbs UV radiation and does not allow it to be transmitted through. Even a very thin sheet of polycarbonate would absorb UV rays and would provide far better protection to the skin and eyes than any sun protection cream.”

Temperature & Impact Resistant
Polycarbonate panels make great plastic roofs because they are resistant to extreme temperatures either or hot or cold. They can stand up to extreme force and are nearly unbreakable when compared to its glass counterpart. Being practically unbreakable with 250 times the impact strength of glass, polycarbonate makes for a great roofing material as it can withstand extreme weather and the severity of nature’s elements such as hail, rain, sleet, snow, and tropical storms.

Long Lasting
Due to its unprecedented reception to UV resistant coatings, polycarbonate plastic roof sheets are long-lasting. Even with constant exposure to the sun, it will not cause the material to discolor, crack, or weaken. Its resilience and durability allow polycarbonate roofs to stand the test of time especially when compared to its glass alternatives.

Great for Sunrooms and Greenhouses
Ideal for sunrooms and greenhouses, polycarbonate plastic roof sheets can soak up the sun even on a cold or cloudy day. It also has the multitude of benefits for these outdoor environments such as high light transmission, thermal insulation, and impact resistance, all qualities which allows herbs, vegetation, and greenery inside of these outdoor structures to grow and thrive.

Cons of Plastic Roofing

While there are a plethora of reasons to use polycarbonate plastic roof sheets for your next outdoor project such as a sunroom, greenhouse, pool or patio cover, there may be one downside to using this super durable material, which is that it can be scratched.
