Why are PVC roofs so special?
Initially introduced in Europe in the 1960s, PVC roofing systems have experienced significant growth. Currently, approximately 65% of the European commercial roofing market is comprised of PVC roofs. PVC is increasing in popularity in the United States – being the first single-ply roofing product to obtain a standard designation from the American Society for Testing and Materials (ASTM D4434). PVC roofs are often referred to as the first “cool roof”, it is environmentally sustainable with a proven long service life.
The rise in popularity is due to a large variety of standout characteristics:
- PVC is notable for its longevity.
- PVC has a proven durability in harsh weather and temperature extremes.
- Low-life cycle costs are a characteristic with PVC roofing.
- Owners of PVC roofs experience energy efficiency and often lower heating and cooling costs.
- PVC roofs have high levels of heat and solar reflectance.
- A notable degree of resistance to flame, chemicals, and grease has been shown.
- PVC roofs are easily maintained.
- Installation is quick, quiet, and relatively clean when compared to other roofing systems.
- PVC roofs are inherently recyclable and re-usable.
- Waste reduction occurs throughout the life-cycle in production, shipment, installation, and post-consumer disposal.
- Only 43% of the PVC membrane composition is derived from non-renewable fossil fuel feed-stocks, as compared with other single-ply and built-up systems with a higher percentage.
- PVC is inherently recyclable – into other roofing materials and new PVC roofs.
- Closed-loop manufacturing reduces the contribution to greenhouse gases.
- PVC manufacturing and installation produces virtually no scrap.
- A PVC roof can often be installed over an existing roof, reducing landfill cost and contents.
- PVC roofing systems require less energy to produce than competitive products.
- A PVC roofing system can assist in earning points under the LEED system in at least 10 categories.
The energy efficiency of PVC roofs is outstanding. Some building owners with PVC roofing systems save up to 40% in annual electric costs due to the roof’s ability to reflect sunlight and solar energy. This figure varies by geographical area, climate, and local energy incentives. Insulation performance is also increased by 25%- 50%, depending on the design*. Rooftop cooling equipment runs more efficiently with a reduced strain from the reflectability of the roofing system, which contributes to better quality indoor air. The urban heat island effects are mitigated as a result of this collective efficiency. In addition, a PVC roofing system may, with the correct system design, increase the useful life of the roof as a whole by up to 75%.*
