If you live in a region where you winterize your pool and get snow on your winter cover, it is rather important to get the snow off of your cover as soon as possible.
Let me tell you why…
If you have an above ground pool, the accumulation of snow on your pool will gravitate toward the center of the pool and can pull the pool walls in, potentially causing damage to the top rail and walls of your pool. It can also cause damage to your cover.
If you have an inground pool, the accumulating snow will weigh down your cover, causing it to stretch, possibly beyond the point of repair. If you have a safety cover, the snow weight could cause stress on the cover and pull the anchors out of your decking or rip out your coping.
The idea is to get the snow off your pool cover to the best of your ability in order to avoid damaging your pool and pool cover. Use a broom to sweep the snow off the cover. DO NOT use a shovel, as this can cause damage to the cover by putting holes in the cover. A long handle broom or a leaf blower will work just fine.
