What Makes PVC Roofing Unique?

PVC (Polyvinyl Chloride) roofing membranes are reinforced thermoplastic layers with plasticizers for flexibility. PVC excels in chemical resistance, puncture resistance, and fire safety. It is commonly used in restaurants, factories, and industrial facilities where exposure to harsh elements and oils is a concern.

PVC Installation Methods

• Heat-Welded Seams: Like TPO, PVC uses hot air welding for a single, waterproof layer.
• Adhered Or Mechanically Fastened: Installs over insulation or roof substrate via adhesives or fasteners.

Key PVC Advantages

• Superior Chemical Resistance: Especially for roofs with grease or industrial discharge exposure.
• High Flame Retardancy: Safer in fire-prone environments than some alternatives.
• Longevity: Well-maintained PVC roofs last 20-30 years or beyond.

PVC Downsides

• Higher Upfront Cost: Tends to be more expensive than EPDM or TPO membranes.
• Brittleness Over Time: May lose flexibility with age and long-term sun exposure.

Rubber Shingles And Rubber Roll Roofing

Modern Alternatives For Residential Roofing

Rubber shingles and roll roofing are made from recycled tires, EPDM, or blends with plastic additives. These products mimic the look of traditional asphalt or slate roofs but provide enhanced durability and hail resistance. Rubber rolls are often used for low-slope residential additions, garages, or sheds.
