Plastic Roofs

Plastic roofing is becoming a great alternative to more traditional roofing materials. The material is versatile, durable and is especially suited to locations with wide temperature ranges. Discover the basics, prices and benefits.

Basics Of Plastic Roofing

While clay, wood, and an asphalt shingle roof have been popular materials for quite some time, new modern materials are finding their place as well. Plastic roofing can be found on more and more buildings. It is usually either PVC, which is a thermoplastic polymer, or a thermoplastic olefin (also called a TPO.) Plastic roofing most often comes as corrugated sheets, much like traditional metal roofs . They can last much longer than many types of roofs, as much as 35 years. They stand up to extreme weather quite well, expanding and contracting as temperatures fluctuate.

Advantages Of Plastic Roofing

Good For Ponding
One important benefit of a plastic roof is the ability to shed water efficiently. While some materials are vulnerable to ponding. Plastic corrugated sheets are welded together using heated air, which removes seams. Moisture is prevented from gathering and is quickly shed from the roof.

Energy Efficient
Because plastic can reflect as much as 90% of UV and other heat rays, it is more energy efficient than many other materials. The high rate of reflection lowers heat absorption and transfer. It can also be a great material in cool weather when properly insulated. Heating and cooling costs can be greatly reduced when compared to more conventional roofs.

Resistant To Fires
Another benefit of plastic roofing is fire resistance. Unlike thatched or wooden roofs, fire has a hard time taking hold and spreads slowly. Plastic is particularly good for roofs with a low slope.

Lots Of Options
Many roofing materials have a limited range of colors and styles. Natural ones like stone, clay, and wood can be tinted and dyed but can only be manipulated so far. Plastic can be created in an unlimited range of sizes, patterns, and colors. Thin sheets are inexpensive but have a shorter life than thicker ones.

Downsides

Low Strength
Plastic roofs are better suited to some places than others. They stand up well to extreme temperature changes and heavy rains, but are less able to hold significant weight. Areas with consistent snowfalls may not be the best places for these. A steep enough slope may help to shed snow quickly enough to make it suitable for moderate snows.

Tends To Shrink
Another potential downside to plastic is the tendency to shrink. If installed perfectly, the plastic panels overlap correctly and will remain nailed in place. A good contractor may cost a bit more but can prevent future leaks.
