The fleece reinforcement offers protection from the oils in bituminous products that would normally damage EPDM rubber and improves puncture resistance meaning that flat roofs can be repaired without removing the existing roof. That said roofs that have suffered water damage and show signs of rot must be removed and replaced with new materials.
