Underground vs Above‑Ground Rollers & Solar Blankets

Choosing the right pool cover and roller system affects convenience, appearance, heating efficiency and overall usability. This guide compares **underground rollers**, **above‑ground rollers**, and **solar blankets** so you can select the best option for your pool, space and budget.

1. Underground Rollers (Hidden Roller Systems) #

Overview #

Underground rollers are hidden within a slim compartment built into the pool deck or nearby area. They deliver a premium, seamless finish with effortless operation.

Pros #

• Completely hidden — the cleanest aesthetic
• Maximises poolside space
• Often automated for effortless use
• No visible clutter or trip hazards

Cons #

• Highest upfront cost
• Must be planned during construction
• Requires drainage + correct structural design
• Limited retrofit opportunities

Best For: Homeowners wanting a resort‑style finish with maximum convenience and minimal clutter.

2. Above‑Ground Rollers #

Overview #

Above‑ground rollers are the most common and flexible option. They sit beside the pool and manually roll the blanket on/off.

Pros #

• Most affordable roller system
• Works with any new or existing pool
• Portable — can be moved during entertaining
• Easy to repair or replace

Cons #

• Visible and occupies poolside space
• Manual effort required (unless motorised)
• Can be bulky on narrow pool decks

Best For: Budget‑focused buyers or retrofit installations where underground rollers aren’t possible.

3. Solar Blankets (With or Without Rollers) #

Overview #

Solar blankets sit on the surface of the water and trap heat while reducing evaporation. They can be paired with either roller type or used alone.

Pros #

• Lowest cost heating solution
• Reduces evaporation by up to 95%
• Warms the pool significantly in sunny weather
• Minimises chemical loss

Cons #

• Must be removed before swimming
• Awkward to handle without a roller
• Lifespan typically 4–7 years depending on quality

Best For: Any pool owner wanting inexpensive heating and water savings.

Final Thoughts #
