Since the early 1960s, PVC roofing has gained significant popularity in commercial, industrial, and institutional structures due to its durability, ability to withstand extreme weather, and cost-effective installation and maintenance. If your roof has recently suffered damage or is nearing the end of its expected lifespan, a PVC roof installation offers numerous advantages.

Types of PVC Roofing Membranes
PVC is particularly well-suited for low-slope and flat roofs. The cost-effectiveness of installation, reduced load on structural components, and resilience to harsh weather conditions have led to the widespread adoption of PVC roofing systems.
Standard PVC Membrane
The standard PVC roofing membrane is a single-ply system designed for long-term protection against water damage and heat reflection.
- Composition: A typical PVC roofing system consists of two layers of membrane with polyester reinforcement in the center. Additives are included to enhance flexibility, and the material can be installed using screws or adhesives.
PVC KEE Membrane
To improve flexibility, stiff components in PVC roofing membranes are adjusted during manufacturing. Liquid plasticizers used in this process may evaporate over time, but PVC KEE membranes retain elasticity longer, extending the lifespan of the roof.
- Features: This type of membrane effectively reflects sunlight and can be used in combination with asphalt.
Fleece-Backed PVC Membrane
For roofs with low slopes or flat surfaces, fleece-backed PVC membranes offer additional support.
- Installation Benefits: High-quality fleece is attached to the underside of the membrane, allowing for easy roll-out directly onto the roof. This innovation reduces labor costs while providing a robust protective layer.
Components of a PVC Roofing System
A PVC roof consists of more than just the membrane; it requires multiple layers of materials, each serving a specific purpose.
- Roof Deck: The hard layer fastened to the structural supports of the building acts as a base for the other components of the PVC roofing system.
- Insulation Layer: Typically installed on top of the roof deck, the thickness and type of insulation depend on local weather patterns and energy efficiency needs.
- Fasteners and Plates: Properly placed fasteners and plates ensure a secure connection between the membrane sheets and the roof deck.
- Adhesives: Depending on weather conditions, adhesives may be the most effective installation method, especially in areas prone to windstorms.
- Flashing and Sealants: Essential for areas where ventilation pipes, HVAC units, or parapets penetrate the roof, flashing and sealants prevent water damage and moisture infiltration.
