PVC RV Roofing That Works Harder and Lasts Longer

Ronald Mark Associates manufactures XTRM PLY® PVC, a high-performance roofing membrane engineered specifically for the RV market. Introduced in 2010, it remains the most solar-reflective white membrane available, designed to keep RV interiors cooler by reflecting infrared energy rather than absorbing it. XTRM PLY® also releases absorbed heat efficiently through emissivity, preventing it from transferring into the RV interior, a dual advantage that rubber and TPO membranes don’t offer.

XTRM PLY® is the only PVC RV roofing membrane made in the USA, manufactured by a US-based workforce committed to domestic production. Choosing it means supporting American manufacturing.

Unlike rubber roofing, which requires regular reconditioning to maintain performance, XTRM PLY® needs nothing more than soap and water. It resists streaking and chalking, holds up against punctures and tears with 30% higher tear resistance than TPO and EPDM, and can be permanently patched using commonly available adhesives, without the need for a professional.

Available in roll lengths from 21′ to 45′, XTRM PLY® PVC RV Roofing is built for both aftermarket replacement and OEM specification.

XTRM PLY® PVC RV Roofing is available through authorized distributors across the United States, serving both the aftermarket and OEM channels. Contact us to be connected with the right distributor for your region and application.

Most Solar-Reflective White Membrane

XTRM PLY® achieves its reflectivity through whitening agents, including titanium dioxide, which deflects infrared energy before it reaches the roof surface. It also releases absorbed heat efficiently through emissivity, preventing it from building up and transferring into the RV interior. The result is a cooler interior without additional insulation and lower demand on your RV’s air conditioning system.

Low Maintenance

Rubber roofing requires periodic reconditioning treatments to prevent cracking and maintain its seal. XTRM PLY® doesn’t. Soap and water is all it takes to keep the membrane clean and performing. A six-month check of your roof sealants is the only routine upkeep recommended.

Unrivaled Strength

XTRM PLY® delivers 30% higher tear resistance than TPO and EPDM rubber roofing systems. Its puncture resistance holds up in harsh conditions where softer membranes fail, whether from debris impact, foot traffic during maintenance, or temperature-driven expansion and contraction. It also resists the streaking and chalking that rubber membranes develop over time, maintaining its appearance without surface treatments.

Proven Performance

Ronald Mark Associates has been manufacturing PVC membranes for the RV market since 2010. XTRM PLY® is produced under ISO 9001:2015 certified processes at our US facilities, with every roll meeting strict quality standards before it ships. That consistency is what makes it a trusted spec for both aftermarket replacement and OEM manufacturing.

The roofing membrane you spec into a new build shapes the ownership experience your buyers will have for years. Low maintenance, easy repairability, and thermal performance are not just product features — they are purchasing considerations that end buyers increasingly ask about before committing to a unit.

Specifying XTRM PLY® PVC gives your sales and service teams a straightforward story to tell. No reconditioning treatments, no seasonal protocols, no specialist repairs — just soap and water for cleaning and a simple permanent patch process when damage occurs. That simplicity reduces post-sale service friction and supports long-term customer satisfaction.

Thermal performance adds another dimension to that story. XTRM PLY® is formulated with titanium dioxide whitening agents for high solar reflectivity, and its emissivity means absorbed heat is released efficiently rather than transferred into the living space. For buyers in warmer climates, that is a tangible comfort advantage tied directly to your roofing choice.

XTRM PLY® PVC is manufactured by Ronald Mark Associates under strictly controlled production processes covering compounding, extrusion, and lamination. Every roll leaves our facilities backed by an ISO 9001:2015 certified quality management system.

We’ve been engineering PVC membranes for the RV market since 2010. When you specify XTRM PLY®, you’re backed by the manufacturer, with the technical knowledge, production consistency, and distributor network to support your project from inquiry to installation.
