Catchwater roof systems and elastomeric paint


I have an earthship, with a rubber (EPDM) roof. The roof is designed to catch rain and snow into a cistern for household use. Is elastomeric paint safe for this kind of roof, or will it contaminate the cistern water? (I do not use the cistern water for drinking, just washing dishes and taking showers)

  1. Elastomeric paint is generally considered safe for use on EPDM roofs designed to catch rain and snow for household use, such as your cistern systems. When selecting elastomeric paint for this purpose, it is crucial to choose a product that is specifically labeled as safe for potable water systems. This designation ensures that the paint does not contain harmful chemicals that can leach into the water and contaminate it.

    Given that you do not use the cistern water for drinking but for non-potable purposes like washing dishes and showering, the risk of contamination may be relatively lower. However, it is still important to prioritize the safety and quality of the water collected in the cistern.

    Before applying the elastomeric paint to your EPDM roof, carefully review the product specifications and ensure that it complies with regulations for water systems. Additionally, consider consulting with a professional in roofing or water systems to confirm the compatibility of the elastomeric paint with your specific setup.

    Routine maintenance and monitoring of the cistern water quality are also recommended to promptly address any issues that may arise from using elastomeric paint on the roof.
