rolldeck: the pool cover you can stand on.
A solid deck that rolls on two rails over your pool for winter, then rolls back in spring. Your covered pool becomes patio space for six months instead of a saggy tarp. Designed by 3DFluid in Broomall, PA. Now reserving 2027 installs.
how a rolling deck pool cover works
RollDeck is one solid deck that rolls on rails. In summer it parks beside your pool as extra deck space. In fall you roll it over the water and it locks closed for winter. In spring you roll it back. The deck is the same size in both positions.
summer: parked
The deck sits beside the pool and works as lounge space while you swim.
fall: roll and lock
Do your normal closing, then hold the key switch while the deck rolls over the pool. It takes about two to three minutes, slow on purpose, and locks closed with a key.
spring: roll it back
Roll the deck back to its spot and the pool is open. No cover to pull off, clean, fold or store.
the good: why homeowners want one
A rolling deck changes what a covered pool is. Instead of hiding the pool under fabric, it turns the pool area into usable floor.
a patio all winter
Put chairs, a fire table or planters on the closed deck. The space you lose to a cover from October to May comes back.
no cover to wrestle
Closing the pool is your normal routine (blow out the lines, add winter chemicals) and then you roll the deck. Nothing to stretch, anchor, drag off or fold.
nothing to store
A safety cover spends every summer folded in your shed or garage. The deck simply parks beside the pool and keeps working as deck space.
no sagging, no puddles
It is a rigid floor, not fabric. Rain and snowmelt drain through the deck instead of pooling on top, so there is no cover pump to run.
cleaner spring opening
Leaves stay on top of the deck where you can blow them off, and the deck shades the water all winter.
built to last
IPE hardwood decking and outdoor-grade materials made to last for decades. Fabric covers are replaced every several years.
rolldeck vs. a regular pool cover
Here is how a rolling deck compares with the covers most Pennsylvania pools use today. Cover prices are typical installed ranges from national cost guides; your quote depends on pool size and shape.
| Mesh safety cover | Solid safety cover | Automatic cover | RollDeck | |
|---|---|---|---|---|
| Typical installed cost | about $1,000–$3,000 | about $1,500–$3,600 | about $8,000–$20,000+ | Quoted after a free measurement |
| Lasts | roughly 10–15 years | roughly 7–11 years | fabric usually replaced every several years | built to last for decades; decking cared for like any deck |
| Walk on it / use it | No | No | No | Yes, it is a deck |
| Opening and closing | Stretch over anchors, then remove, fold and store | Same, and heavier; pump off water first | Key switch | Roll it closed, it locks |
| Water and debris on top | Lets fine dirt and some sunlight through | Holds water; needs a cover pump | Holds water; needs a cover pump | Water drains through; leaves stay on top and blow off; no pump |
| Pool shapes | Almost any | Almost any | Best on rectangles | Rectangles and near-rectangles |
| Certified safety cover (ASTM F1346) | Yes, if certified and installed right | Yes, if certified and installed right | Yes, on certified models | Not certified; your pool barrier is still required |

the honest downsides
A RollDeck is not right for every yard. We would rather tell you now than at the measurement.
it needs parking room
The deck has to park somewhere when the pool is open, so you need clear, fairly level space at one end of the pool about as long as the pool itself, or about half that at each end with our two-piece version.
it costs more than fabric
A solid rolling deck costs more than a mesh cover. It makes sense when you want the winter patio and the no-cover routine, not when you only want the cheapest cover.
shape matters
Rails are straight, so rectangles and near-rectangles work best. Freeform pools, raised walls or rock features at the edge may rule it out.
you will see the track
On existing pools the deck sits about one step above the patio and the track runs along both sides of the pool all year. On new pools we can set it close to flush with the patio.
it is a new product
RollDeck is a 3DFluid design and the images on this page are concept renderings. We are measuring yards and reserving 2027 installs now.
not a safety certification
A locked solid deck is a strong cover, but RollDeck is not certified to the ASTM F1346 safety cover standard. Pennsylvania code still requires a proper pool barrier such as a fence and self-closing gate.
is your pool a good fit?
good fit
Rectangular or near-rectangular inground pool, concrete or fiberglass, with open patio or lawn at one end. You want to use the pool area in winter and stop dealing with a cover.
maybe
Not enough room at one end? Our two-piece version parks half at each end. Steps or a slope at the parking end can often be solved too, and we check at the measurement.
not a fit
Freeform pools, pools with rock waterfalls or raised walls on the long sides, or no room at either end to park the deck.
Building a new pool? Plan the RollDeck from day one with a fiberglass pool or custom concrete pool and we design the rails and parking zone into the patio.
from measurement to first winter
Every RollDeck is built for one specific pool.
free measurement
We measure the pool, the parking end and the grades, and tell you on the spot if your yard is a fit.
3d design
We model your backyard in 3D with the deck open and closed, so you see exactly where it parks and how it looks.
permit and engineering
We handle the township permit and the engineering.
site prep
We prepare the patio along the pool and the parking area.
install
We build and install your RollDeck and test it before handover.
first closing
We do your first winter closing with you and show you how to run the deck.
rolldeck questions
What is a rolling deck pool cover?
It is a rigid deck that rolls on rails over a swimming pool to cover it, then rolls back off to open it. When it is closed, the pool area becomes walkable patio space. When it is open, the deck parks beside the pool and works as extra deck space.
Can I walk on it and put furniture on it?
Yes. It is designed as a deck, not a fabric cover, so chairs, tables and people can be on it when it is closed and locked.
Does it replace my safety cover or pool fence?
It replaces the winter cover you install and remove each year. It does not replace your pool barrier: RollDeck is not certified to the ASTM F1346 safety cover standard, and code still requires a fence or other approved barrier.
Do I still need to winterize the pool?
Yes. You still blow out the lines and add winter chemicals. What goes away is installing, anchoring, pumping off, removing and storing a cover.
How much does a RollDeck cost?
It depends on the pool size, the parking zone and the decking you choose, so we quote after a free measurement.
Will it work on my existing pool?
Often, if the pool is rectangular or close to it and you have room at one end to park the deck. We confirm it at the free measurement.
What about snow?
RollDeck is designed for Pennsylvania winters. Clear heavy snow before rolling the deck open, the same way you would before using any deck.
Is it safe while it moves?
It only moves while you hold the key switch, and safety sensors stop it if something is in the way. Nobody should be on the deck or in the pool while it moves. When it is closed, it locks with a key.
Where do you install RollDeck?
We are based in Broomall and install across Delaware, Chester, Montgomery and Bucks counties and Philadelphia. See all areas we serve.
