Other reasons EPDM may become damaged

RubberCover and other high quality EPDM membranes are hard wearing, developed to withstand weathering and remain UV stable. This contributes to the exceptional service life and makes them hard to damage.
There are no specific materials that can adversely affect EPDM, and the damage that does occur is often accidental. This can be from debris, such as an overhanging tree branch or other wind carried item that may land on the surface during a storm.

During installation, it is advised that you wear suitable footwear when handling the membrane. This can help to minimise the risk of puncturing the EPDM with footwear or foot-carried sharp debris.

How to repair EPDM

Should EPDM become damaged, it is often easy to repair, particularly if the damage is small, such as a puncture or tear. Patch repairs can be straightforward to carry out using an EPDM patch and the right primer, adhesive and sealant. 

EPDM can also be repaired with liquid PU in an emergency. This can be long term, or depending on the nature of the repair, a liquid solution can also provide a temporary fix while waiting for a professional repair.
