Dicor DiFlex TPO RV Roof Membrane | 35 Mil | 9.5' | 3 Colors

Modern RVs demand better, more flexible roofing membranes for their complex designs — the Dicor TPO DiFlex Rubber Roof Membrane delivers that flexibility with 35-mil thickness, exceptional stretch, and 20-year manufacturer warranty. Available in Polar White, Bright White, and Tan across multiple lengths (20', 30', 40', 50') to fit your specific RV project.

Color and Length Options

Select your specific configuration from the variant options:

• Colors: Polar White, Bright White, Tan
• Lengths: 20', 30', 40', 50'
• Width: 9.5' (standard across all variants)

Superior to PVC

Highly Flexible + Stretchable

Simple Maintenance

Normal maintenance is simple — no special materials required:

• Periodic cleaning 3-4 times per year
• Non-abrasive household cleaner (like dish soap) with medium-bristled scrub brush
• Avoid harsh or highly abrasive products
• Thoroughly rinse roof and sidewalls to remove soap residue
