Benefits of Using a Pool Cover
Investing in a pool cover offers immediate and long-term benefits that often outweigh the initial cost. Let’s explore these in more detail.
Reduced Evaporation
One of the most overlooked problems in pool maintenance is water loss due to evaporation. In a typical outdoor pool, several hundred gallons of water can be lost each month, depending on climate and exposure.
Using a cover can reduce evaporation by up to 95%, which in turn preserves your investment in water treatment chemicals like chlorine and algaecide.
Energy Efficiency
For pools heated by gas, electric, or solar heaters, a thermal cover significantly cuts down on energy usage. When not in use, pools lose heat rapidly, particularly at night.
By using a solar cover, the water temperature can rise by 8–15°F (4.5–8.5°C), depending on sun exposure and atmospheric conditions. This means pool owners can enjoy a longer swimming season without a significant increase in heating costs.
Lower Chemical Consumption
Because pool covers reduce water evaporation and minimize sunlight exposure, the effectiveness of pool treatments improves. Sunlight degrades chlorine and lowers pH balance, requiring more frequent chemical adjustments.
By covering your pool, you can reduce chemical use by 30–60%, depending on the type of cover you use and how often it’s deployed.
Safety for Children and Pets
Tragic accidents involving young children and pets can often be prevented with safety covers. A properly installed solid safety cover can support the weight of an average adult, acting as a protective barrier when the pool is not in use.
According to the Centers for Disease Control and Prevention (CDC), drowning is the second leading cause of unintentional injury death among children ages 1–14. Pool covers, combined with fences and alarms, can further reduce the risk.
Less Maintenance and Cleaning
With fewer leaves, pollen, dirt, and insects entering the pool, you will spend less time vacuuming, skimming, and backwashing filters. This not only saves time but also extends the life of your pool equipment.
Improved Water Clarity and Reduced Algae Growth
By limiting sunlight penetration, pool covers hinder algae growth. Pools that are left uncovered, particularly during fall and spring, are more prone to algae blooms.
Covers also help maintain even water chemistry, reducing the frequency of shocking and rebalancing.
Drawbacks and Considerations
While pool covers come with many benefits, there are some considerations that may influence your decision.
Upfront Cost
The cost of pool covers varies significantly. A solar cover can cost anywhere between $50 and $300 depending on size and thickness. Safety covers can run into the thousands, especially if professionally installed. Automatic covers, meanwhile, often start around $5,000 and move upward from there.
However, when viewed as a long-term investment, many types of pool covers pay for themselves over time via energy savings and reduced chemical use.
Storage and Handling
Manual covers can be heavy and bulky, especially in large pools. Storage can become a challenge, as improper folding can lead to tearing and wear. Automatic covers eliminate this concern but come with much higher installation requirements and costs.
Maintenance and Longevity
The life span of a pool cover depends on the type and usage. Solar covers typically last two to three seasons, depending on UV exposure. Safety and winter covers can last five years or more if properly maintained. Mold, mildew, and UV degradation are common issues if the cover is not dried and stored correctly.
Incorrect Use Can Cause Damage
Using the wrong type of cover for the season or purpose can lead to unnecessary wear or even damage. For instance, using a thermal solar cover during winter might trap moisture that harms the pool walls and tile line.
Proper installation and adherence to seasonal use guidelines are crucial to maximizing the effectiveness and durability of your pool cover.
When You Really *Need* a Pool Cover
While some pool owners view a cover as optional, there are specific situations where it becomes more of a necessity than a luxury.
Lack of Pool Fencing or Barriers
If your pool lacks a secure fence, gate, or other safety barriers, a safety cover can act as an additional safeguard. This is particularly important in residential areas where children may visit unexpectedly or where local regulations require additional protective measures.
Dense Pollen, Leaf, or Insect Infestations
If you live in an area with tall trees, brush, or high amounts of airborne pollen, keeping your pool clean without a cover becomes a constant chore. Similarly, if insects like mosquitoes are a problem, covering the pool at night can disrupt breeding cycles and minimize infestations.
High Swimming Season with Heated Pools
If you use a pool heater to extend your swimming season, a solar cover is essential. Without a cover, the majority of the heat added during the day will be lost overnight, increasing your utility bill.
Regions with Water Restrictions
In areas affected by drought or water scarcity laws, pool covers are practically mandatory. They reduce water loss from evaporation, helping pool owners retain every precious drop.
Swim Spas or Smaller Pools
Swim spas and plunge pools lose heat more quickly due to their smaller surface area. As a result, using a thermal cover can significantly offset heating costs.
When a Pool Cover Might Not Be Necessary
There are situations where pool covers are not as essential. For example:
Pools Used Frequently
If your pool is used daily, adding and removing a cover might become inconvenient. That said, automatic covers or mesh summer covers offer a compromise by providing some benefits without the hassle of repeated removal.
Strong Pool Circulation and Filtration
Modern pool systems equipped with efficient circulation and filtration may reduce the impact of evaporation, debris accumulation, and algae growth. However, this does not eliminate the need for a cover entirely but simply makes it less critical.
Underground or Indoor Pools
Pools located indoors or underground are naturally protected from environmental factors like wind, debris, and direct sunlight. However, even these can benefit from a thermal cover or safety cover depending on family needs.
Low Budget
If you are budget-conscious and do not notice extreme water loss, energy cost increases, or safety issues, you can delay purchasing a cover. However, the long-term savings from regular use should not be ignored.

While pool covers are beneficial for nearly all types of pools, the necessity of using one may vary based on factors such as climate, pool usage, and maintenance habits. For in-ground and above-ground pools, covers help with heat retention, water conservation, and debris control. For safety reasons, pool covers, especially rigid and safety covers, are highly recommended for households with children or pets.
However, in very warm regions where pools are used year-round and evaporation is less of a concern, some owners might choose not to use a cover. Still, even in these situations, pool covers can offer protection against unexpected weather and contribute to better chemical balance. Ultimately, regardless of the pool type, the right cover can enhance pool management and safety.
Can a pool cover help save money on maintenance costs?
Yes, a pool cover can significantly reduce maintenance costs by minimizing the buildup of debris and the loss of chemicals and water. With a cover in place, dirt and organic matter are kept out of the pool, meaning less time spent skimming and vacuuming and a lower chance of algae growth. This also reduces the amount of chlorine and other chemicals needed to maintain proper water balance.
Moreover, because pool covers prevent water evaporation, owners don’t have to refill the pool as often, which saves on water bills and the energy costs associated with heating new water. Additionally, automatic pool covers or insulated thermal covers can protect pool equipment from weather-related wear and tear, extending the life of pumps, filters, and liners, thereby saving on replacement and repair expenses.
Do pool covers help prevent accidents and injuries?
Some types of pool covers, particularly safety covers, are specifically designed to prevent accidents and provide an added layer of protection. A properly installed safety cover can support the weight of a child or pet that might accidentally fall onto it, serving as a barrier that helps prevent drownings. Safety covers are often required by law in areas where backyard pools are common and used for safety compliance.
While solar or thermal covers provide less structural strength, they still keep the water surface free of debris and reduce the visibility of the water, discouraging unsupervised access. For families with young children or pets, combining a safety cover with additional protective measures like fencing and alarms can create a comprehensive childproofing system that gives pool owners greater peace of mind.
How do pool covers affect chemical balance and water quality?
Pool covers can greatly improve water quality by reducing contamination from external elements like leaves, pollen, and dust. When fewer contaminants enter the water, the chemical balance remains more stable, requiring less frequent adjustments and reducing the overall chemical usage. This is especially useful in areas where trees, wind, or wildlife introduce a lot of organic debris into the pool.
Moreover, since pool covers limit evaporation, they help maintain steady water levels, which in turn supports optimal filtration and circulation. Evaporation can increase the concentration of minerals and chemicals in the pool, potentially causing scaling or cloudiness. By maintaining a more consistent environment, a pool cover contributes to cleaner, safer swimming conditions and makes routine maintenance less labor-intensive.
What types of pool covers are available, and which is best for me?
There are several types of pool covers available, each designed for specific purposes.
