Most issues associated with floating covers come from outside forces. This may include damage from extreme weather conditions such as high winds, storms, or heavy snowfall, which can cause tears or dislodge the cover. Over time, exposure to UV rays may degrade material that isn't UV resistant.
Accumulation of debris or algae on the cover surface can add weight and strain, potentially causing sagging or sinking. Improper installation or inadequate anchoring can result in the cover shifting or becoming uneven, reducing its efficiency.
