There’s been a shift in commercial roofing over the last few decades, from multi-ply, or built-up roofing (BUR) options that require layers upon layers of asphalt and roofing felts, to single-ply roofing, which installs a single, thermoplastic, PVC, or ethylene layer directly atop insulation. Both offer durability and longevity. But single-ply roofing offers several advantages that BUR does not, which explains its popularity.
Benefits of Single-Ply Roof Systems in Commercial Roofing
First and foremost, single-ply roofing is much more energy-efficient than multiple dark, heavy layers of tar and gravel. When manufactured in light colors that reflect the sun’s heat instead of absorbing it, single-ply sheets can greatly increase a building’s energy efficiency. According to the U.S. Department of Energy, a cool roof can remain as many as 50 degrees cooler than a traditional, dark roof under the same summer conditions. But single-ply roofing has other advantages, too:
- It requires less labor and materials, which lowers the cost of installation.
- It can be manufactured to fit unconventional roof designs.
- It’s much more lightweight.
- It’s impact-resistant.
- It’s resistant to UV radiation and ozone.
- PVC single-ply holds up well under the grease and oil emitted by exhaust fans.
- For commercial roofing, especially within the food-service industry, PVC single-ply roofing is a solid consideration.
Composition of Single-Ply Roofing
While traditional BUR uses multiple applications of hot or cold asphalt or a similar substance, interspersed with multiple layers of roofing membrane, single-ply roofing places a single, thermoplastic polyolefin (TPO), polyvinyl chloride (PVC), or Ethylene Propylene Diene Monomer (EPDM) material directly over insulation. Typically long fasteners or adhesive is used to keep the material in place, and flashing is added around vents, windows and openings to keep precipitation at bay.
The material that forms the final layer of single-ply roofing has been treated to reflect UV light, which contributes to its energy efficiency. All types are provide excellent resistance to fire, weather, chemicals, and punctures. If you’re searching for viable options in commercial roofing that are cost-effective and will last a long time, single-ply roofing may be the answer.
