Key Features of 45 mil EPDM Rubber Roofing
Cost-Efficiency: The most economical rubber roofing membrane in our lineup, offering long-term waterproofing at a budget-friendly price point.
Lightweight & Flexible: At 45 mil, the membrane is easy to maneuver, making it ideal for the complex curves and penetrations found on RV roofs and residential structures.
Superior Weatherability: This epdm membrane is inherently resistant to UV rays, ozone, and acid rain, ensuring a service life of 15–20+ years.
No Plasticizers: Unlike PVC, our epdm rubber roofing membrane contains no plasticizers, meaning it stays flexible and won't become brittle over time.
Primary Applications of 45 mil EPDM Roofing
RV & Motorhome Roofing: Lightweight, vibration-resistant, and easy to bond to aluminum or plywood substrates.
Residential Garages & Sheds: Provides a professional-grade seal for backyard structures and home extensions.
DIY Flat Roofs: The 45 mil thickness is more easy for non-professionals to install using cold-applied adhesives.
Carports & Patios: A quick, durable solution for outdoor shelters requiring 100% moisture protection.
