Rubber roofing reduces maintenance tasks such as sealing and prevents leaks, seam splitting and pitting. Rubber roofs are made of Ethylene Propylene Diene Monomer (EPDM), a tough material resistant to decay. Regular cleaning of the rubber roof is necessary to prevent mold from building up and stains from appearing. Rubber cleaning is necessary quarterly to reduce the chances of dirt buildup and to remove debris.

Sweep off debris such as leaves and twigs by using a soft-bristle broom before washing.

Fill a bucket with water and regular dishwashing detergent. Agitate the water to make soap suds.

Check all seams of the roof for leaks while cleaning.
