SYSTEM OVERVIEW
What is PVC Roofing?
Polyvinyl Chloride, commonly known as PVC, is a flexible single-ply roofing membrane used primarily on commercial and industrial buildings with flat or low-slope roofs.
PVC roofing membranes are typically installed over insulation and secured using an approved attachment method. The seams between membrane sections are heat-welded together, creating a continuous roofing surface designed to resist water intrusion.
PVC membranes are commonly available in light, reflective colors and are engineered to withstand ongoing exposure to sunlight, moisture, and changing weather conditions.
Benefits & Considerations of PVC Roof Systems
Benefits of pVC
Heat-Welded Seams
PVC membrane sections are joined using heat-welded seams, creating strong connections that help protect the building against water intrusion.
Chemical and Grease Resistance
PVC roofing is resistant to many chemicals, oils, and grease, making it a practical option for restaurants, commercial kitchens, manufacturing facilities, and other demanding environments.
Reflecting Roofing Surface
Light-colored PVC membranes can reflect sunlight and reduce heat absorption at the roof surface, potentially helping improve a building’s energy performance during warmer months.
Weather Resistance
PVC roofing systems are designed to withstand exposure to UV radiation, moisture, wind, and changing weather conditions.
Flexible Roofing Material
PVC membranes can accommodate normal movement within a roofing system and can be installed around penetrations, rooftop equipment, and other roof features.
Durable Commercial Roofing Solution
When properly designed, installed, and maintained, PVC can provide dependable long-term performance for commercial properties.
Important Considerations
- The performance of a PVC roof depends on more than the membrane itself. Proper installation of seams, flashing, penetrations, drains, roof edges, transitions, and other details is essential.
- Existing roof conditions should also be evaluated before installation. Depending on the building and current roofing system, additional preparation or removal of existing materials may be necessary before a new PVC system can be installed.
- Because PVC and TPO are both single-ply roofing membranes, they may appear similar at first glance. However, the materials have different characteristics, and one may be better suited to a particular building or operating environment.
IDENTIFY ISSUES EARLY WITH ROUTINE MAINTENANCE
PVC Roof Maintenance Expectations
PVC roofing is designed for relatively straightforward maintenance, but regular inspections remain important for protecting the roofing system and identifying problems early.
A PVC roof should be periodically inspected for issues such as:
Punctures, cuts, or membrane damage
Damaged or deteriorated flashing
Problems around roof penetrations
Seam damage
Debris around drains and drainage areas
Standing water
Damage around rooftop equipment
Deteriorated sealants
Storm-related damage
Commercial roofs should also be inspected after HVAC technicians, electricians, or other contractors perform work on the rooftop. Tools, equipment, and repeated foot traffic can potentially damage the roofing membrane.
When problems are identified early, localized PVC roof repairs may be possible without replacing the entire roofing system.

| System | Lifespan | Cost | Key Advantage |
| EPDM | 20-30 Years | $ | Low cost, easy repair |
| TPO | 15-25 Years | $$ | Energy Efficiency |
| PVC | 20-30 Years | $$$ | Chemical Resistance |
| METAL | 40-70 Years | $$$$ | Longevity |
EPDM
TPO
PVC
METAL
EPDM (rUBBER)
What it is: Single-ply synthetic rubber membrane (usually black).
Pros:
Cost-effective
Excellent weather resistance
Easy repairs
Cons:
Black surface absorbs heat (higher cooling costs)
Seams rely on adhesives/tapes
Best for: Budget-conscious projects and large flat roofs.
TPO (Thermoplastic Polyolefin)
What it is: White, reflective single-ply membrane with heat-welded seams.
Pros:
Energy efficient (reflects UV)
Strong seams (heat-welded)
Resistant to mold/dirt build up
Cons:
Quality varies by manufacturer (Asscher sources the best quality TPO)
Can age faster in extreme conditions
Best for: Energy-efficient buildings in warmer climates.
PVC (Polyvinyl Chloride)
What it is: Durable single-ply membrane similar to TPO but more chemical-resistant.
Pros:
Highly resistant to chemicals, grease, and fire
Strong, long-lasting seams
Reflective and energy-efficient
Cons:
More expensive than TPO/EPDM
Can become brittle over time
Best for: Restaurants, factories, or buildings with chemical exposure.
METAL
What it is: Panels made of steel, aluminum, or other metals (often standing seam).
Pros:
Extremely long lifespan (40–70 years)
Durable against weather and fire
Low maintenance
Cons:
Higher upfront cost
Noise (rain/hail) if not insulated
Best for: Sloped commercial roofs or long-term investments.
