What Is Roller Burn?

Roller Burn is when the pool cover is stored on the roller without the over cover being used to protect the pool cover.

What happens is the sun passes down through the layers, increasing in heat from layer to layer…superheating the pool cover. The compounding heating effect always happens in the same place at the top of the pool cover roll (as the pool cover is always wound up the same way).

Identifying roller burn can be difficult in the early stages, however there are a few tell-tale signs you can look out for.

  1. Pool covers can shrink up to 1% of their length with how they are made however they simply can’t shrink in their width naturally. If the pool cover has shrunk in the width, it is typically the first sign of it being stored on the roller without the over cover in place. The pool cover will shrink at the corners first, then in the width as the Roller Burn becomes more visible.

  2. Roller burn lines are easily spotted as the Roller Burn has ‘shrunk’ the pool cover material in superheated lines across the pool cover - in line with the top revolutions of the roller. These lines are approximately every 600mm and they start from about the second layer of pool cover down from the top of the roll. Depending on how long the damage has been occurring and how long the pool cover is, it will go almost all the way to the other end.

The pool cover will still operate normally regardless of the lines and shrinkage; the only adverse effect will be in the life of the pool cover. Typically we find where the overheating of the roller burn has occurred, the life of the pool cover decreases.
