PVC Roofing Membrane
A PVC roofing membrane is a premium single-ply roofing system engineered for commercial buildings that demand
exceptional durability, chemical resistance, and long-term performance. PVC is frequently specified for facilities where
exposure to oils, grease, chemicals, or rooftop contaminants can shorten the life of other membrane types.

What Is a PVC Roofing Membrane?
PVC (polyvinyl chloride) roofing membranes are thermoplastic single-ply systems that are heat-welded at the seams,
creating a continuous, watertight surface. Versico’s PVC systems utilize KEE HP (Ketone Ethylene Ester)
technology, which enhances flexibility, chemical resistance, and long-term weathering performance.
Unlike standard plastic membranes, KEE HP-modified PVC maintains pliability over time and resists plasticizer migration,
helping the membrane retain strength and flexibility throughout its service life.

Versico PVC & KEE HP Roofing Systems
Why PVC (KEE HP) Is Specified for Demanding Commercial Environments
PVC roofing membranes are often selected when roof conditions or building use present challenges for other systems.
KEE HP PVC excels in environments where chemical exposure, rooftop runoff, or frequent maintenance traffic are concerns.
- Excellent resistance to oils, grease, and chemicals
- Superior performance near restaurant exhausts and industrial vents
- Heat-welded seams for strong, consistent watertight performance
- Reflective membrane options for energy efficiency
Common applications include restaurants, food processing facilities, manufacturing plants, laboratories,
distribution centers, and mixed-use commercial buildings.
Versico PVC (KEE HP) System Options
Versico manufactures multiple PVC configurations to match performance requirements and building design criteria.
- KEE HP PVC Membranes: Enhanced flexibility and chemical resistance
- Multiple Thicknesses: Commonly 50-mil, 60-mil, and 80-mil options
- Reinforced Sheets: Added puncture resistance and dimensional stability
- Fully Adhered or Mechanically Attached Systems
Certain Versico PVC assemblies are eligible for extended manufacturer warranties when installed by a certified contractor
and designed to specification.
Why Contractor Certification Matters for PVC Roofing
PVC roofing systems rely on precise heat-welded seams and manufacturer-approved installation details.
Improper welding temperatures, rushed installations, or incorrect system selection can compromise performance and warranty eligibility.
- Proper hot-air welding techniques
- Correct membrane thickness and reinforcement selection
- Approved flashing and accessory details
- System design that aligns with warranty requirements
Working with a Versico Certified Contractor helps ensure the roof system is installed to manufacturer standards
and performs as intended over the long term.
When a PVC Roof Should Be Inspected
- Leaks near exhaust fans or chemical discharge areas
- Seam deterioration or membrane discoloration
- Grease or oil accumulation on the roof surface
- After equipment changes or tenant improvements
- Before purchasing or selling a commercial property
Our inspections focus on seams, flashing, penetrations, drainage, and areas exposed to contaminants that accelerate roof wear.
