Can you leave a leaf cover on a pool during the winter?

When it comes time to close your swimming pool, one question often comes up among owners: can you leave a leaf cover on a pool throughout the winter, or should you remove it? Leaf nets have a specific role to play in the fall, but their place during the cold season is a matter of debate. Between saving time, protection, and risks related to the weight of snow or ice, the choice deserves careful consideration.

 

Role of a pool leaf cover

A leaf cover, sometimes called a leaf net, is primarily used to catch dead leaves and debris that would otherwise end up at the bottom of the pool. It simplifies maintenance, keeps the water clearer, and prevents clogging of the skimmer, bottom drain, or filter.

Unlike a solar cover, which protects the water and limits evaporation, a leaf net has a very specific role, especially in the fall. This is when trees lose their leaves and pools become particularly vulnerable to the accumulation of organic matter and other debris.

So the question is simple: can this net, which provides such good protection in the fall, remain in place throughout the winter season under snow and ice?

 

Can a leaf net be left on an above-ground pool during winter?

In the case of an above-ground pool, sometimes called an in-ground pool, the answer depends directly on the configuration and type of cover already provided for winterization.

When an opaque pool cover or winter cover is already in place, the leaf net loses its usefulness and should generally be removed.

If it remains in place, the weight of the snow and the expansion of the ice may deform it and weaken the structure of the pool. These pools are particularly sensitive to the lateral pressure exerted by frozen water, and an additional load that is poorly distributed can damage the pool wall or pull on the fasteners. In such circumstances, caution often dictates that the net should be removed before winter and stored away.

 

Can a leaf cover be left on an in-ground pool during the winter?

For an in-ground pool, the situation is not quite the same. The net can sometimes be kept in place in addition to a sturdy winter cover, providing extra protection. Debris does not accumulate on the main cover, making it much easier to open the pool in the spring.

However, using only a leaf cover during the cold season is rarely recommended. Snow and ice always end up weighing down the net, which can become deformed or torn.

Your pool manufacturer often provides clear instructions on the type of cover to install during the cold season and under what conditions it can withstand Quebec’s winter climate. Pool owners should refer to these instructions to avoid damaging their investment.

 

Advantages of leaving the leaf net on your pool during winter

Some owners still choose to keep their leaf net on during winter, especially in regions where winters are less harsh or when they have a sturdy net designed to withstand heavy loads. The advantages are real:

• Reduced spring cleaning: leaves and branches are held on the surface, preventing them from getting stuck in the skimmer or pipes. 
• Limited deposits at the bottom of the pool: fewer leaves at the bottom of the pool means less need to vacuum or backwash the filter when opening the pool.
• Additional protection against UV rays: the net can provide additional protection against UV rays, which tend to weaken winter covers that are exposed to them all the time.
• Prevents damage to the main cover: the net prevents debris from damaging the main cover prematurely.

 

Risks and limitations of leaving the leaf net on a pool in winter

Leaving a leaf net in place also has disadvantages:

• The net is not designed to hold heavy loads such as snow and ice. The accumulated weight can stretch, tear, rip, and even damage the coping.
• If the water level is lowered too much, the cover can pull on the anchors and weaken the pool.
• Poor drainage is another potential problem if the water does not drain properly: a poorly tensioned cover promotes water stagnation, which increases freezing and makes the structure more vulnerable. 
• Even though some covers are treated against UV rays, prolonged exposure during the winter can eventually weaken the fibers, especially if the cover is not made of UV-resistant materials.

The advantage of simplifying maintenance in the spring must therefore be weighed against these very real risks.

 

How to secure your pool cover in winter

For those who decide to keep their net in place even in winter, certain precautions are necessary. 

The cover must be tightly stretched and secured according to the manufacturer’s instructions. The fasteners must be able to withstand the wind and freeze-thaw cycles that characterize the cold season. Regular monitoring is also necessary to remove excess snow and prevent the net from bending under the weight. Finally, combining a leaf cover with a sturdy winter cover remains the best strategy for limiting risks.

 

Alternatives to leaf nets for pools in winter

To avoid any risk, many people prefer to use leaf nets only in the fall and, when winter arrives, store them in a dry place when the pool is closed. Effective alternatives:

• Installing an opaque tarp or a solid cover designed specifically for winter and to support the weight of snow and ice will provide much better protection.
• Opting for a custom-made cover, tailored to the exact dimensions of your pool and capable of supporting the weight of snow.

 

Preparing your pool for winter effectively: key steps

The leaf cover is only one part of closing your pool. The following steps are essential to protect your pool from the harsh Quebec winter:

1. Clean the bottom of the pool with a vacuum cleaner to remove debris.
2. Adjust the water chemistry: pH, alkalinity, chlorine level.
3. Add the chemicals recommended in your closing kit.
4. Lower the water level below the skimmer and bottom drain.
5. Partially drain and backwash the filter. Set the filter to the winter position.
6. Empty the pipes, install drain plugs, and add antifreeze or Styrofoam to the pipes.
7. Install plugs on the skimmer and valve.
8. Install a leaf net or sturdy tarp over your pool.

These steps will prevent ice from damaging your pool and make it easier to reopen in the spring.

 

Choose a specialist in pool leaf nets

So, can you leave a leaf net on a pool for the winter? Technically yes, but it is recommended that it be used in addition to a sturdy winter cover. Using only a net exposes the pool to high risks.

Each type of pool, above ground or in-ground, has its own specific characteristics, and Quebec’s climate requires high-quality materials. To protect your pool during the winter, it’s best to opt for custom-made leaf covers and nets that are UV-resistant and capable of withstanding snow and frost.

At Toiles GR, a manufacturer of custom-made covers and tarps, we produce high-end pool leaf nets that are adapted to Quebec’s climate. Before closing your pool, call on specialists who can advise you on the most suitable type of cover or net. Installing a well-designed cover today will save you a lot of trouble in the spring.
