PVC Roofing for Low-Slope Commercial Roofs

---

PVC (Polyvinyl Chloride) roofing is a single-ply membrane system designed for low-slope commercial roofs. Known for its strength, chemical resistance, and heat-welded seams, PVC is commonly used on commercial buildings that require long-term durability and reliable waterproofing. 

PVC roofing is a single-ply thermoplastic membrane reinforced with polyester or fiberglass. The sheets are installed across the roof surface and joined together using hot-air welding, creating a continuous, watertight membrane.

Because of its performance characteristics, PVC is frequently specified for commercial and industrial buildings, especially where durability and seam strength are critical.

PVC roofing systems can be installed using multiple attachment methods depending on building requirements. A typical assembly includes:

• Roof deck (structural base)
   
• Vapor barrier (when required)
   
• Insulation
   
• PVC membrane (fully adhered, mechanically fastened, or ballasted)
   
• Heat-welded seams and flashing details
   

The hot-air welding process fuses membrane seams, providing consistent waterproofing across the roof.

PVC roofing is often selected for commercial applications because of its performance advantages:

• Heat-welded seams: Strong, watertight seam integrity
   
• Chemical resistance: Performs well around grease, oils, and rooftop exhaust
   
• Long-term durability: Reinforced membranes resist punctures and wear
   
• Low-slope compatibility: Designed for commercial roof layouts

PVC roofing systems can be installed using different attachment methods based on wind ratings and roof design.

Fully adhered systems bond the membrane directly to the insulation, offering a smooth appearance and reduced movement.

Mechanically fastened systems secure the membrane with fasteners and plates, allowing efficient installation and reliable performance for many commercial buildings.

PVC roofing is a strong choice for commercial buildings that need durability, chemical resistance, and secure heat-welded seams. The best system depends on drainage, insulation requirements, and how the roof is used.
