EPDMROOFING
EPDM roofs were designed to become oxidized. The layers that are lost from oxidization over time improves the longevity against UV and ozone rays. However, Polk says that this should not be a concern. Over a span of 10-12 years, about 10% of the roofs overall thickness will be lost. EPDM roofs have gray and white streaks that appear on the sides of the RV and in addition, becomes extremely slippery when wet.
