Oklahoma Decks Waste the Space Below Them
Sunspace by Express Sunrooms of Oklahoma installs under-deck panel systems for Oklahoma homeowners who have an elevated deck with usable square footage below it that is currently unusable because rain falls straight through the deck boards.
The space below an elevated deck is already covered by the deck above. It is sheltered from direct overhead sun. In Oklahoma, where outdoor living space is valuable for a short window of genuinely comfortable weather each year, that wasted square footage represents real lost value.
Under-decks panels turn that wasted space into a functional year-round outdoor living area: dry during OKC spring rain, sheltered in summer heat, and usable for entertaining, outdoor kitchens, storage, or relaxation regardless of what the weather is doing on the deck surface above.

How the Under-decks Panel System Works
Any existing or new elevated Oklahoma deck where the space below is not being fully used because of rain drip-through.
The Under-decks panel system utilizes precision-fabricated, pitched aluminum ceiling panels installed beneath deck joists. This pitch directs captured water into a gutter and downspout system, routing it away from the space below.
A rain-resistant panel locking system seals every joint, preventing drips. The result is a dry ceiling surface, even during typical Oklahoma rain. All components—panels, gutter, and downspout—are powder-coated aluminum, requiring no painting, sealing, or annual treatment.

Under-decks Panel FAQs: Oklahoma Homeowners Ask
Honest answers to every question Oklahoma homeowners ask before, during, and after their window project.
What is an Under-decks panel system, and how does it work?
An Under-decks panel system is a ceiling installed beneath an elevated deck’s joists. This system uses precision-fabricated, slightly pitched aluminum panels and a locking system to capture rainwater passing through the deck boards, directing it to an aluminum gutter and downspout. The result is a clean, finished ceiling that creates a complete, dry, rain-resistant space below the deck.
Does an Under-decks panel system require any modification to the deck above?
No. The Under-decks panel system attaches to the underside of the existing joist structure without modifying the deck surface, deck boards, or visible deck framing.
The deck above continues to function exactly as it did before installation. Only the space below changes.
Can Under-decks panels be installed on an existing deck?
Yes. Under-deck panels can be installed on any elevated deck with a sound joist structure at any time. The deck does not need to be new or recently built.
We assess the joist condition and spacing at the free consultation to confirm the installation approach. If the joists are sound, the panel installation proceeds without any structural modification.
Can Under-decks panels be combined with a new AlumaDeck or Trex deck installation?
Yes. Installing Under-decks panels at the same time as a new AlumaDeck or Trex composite deck is the most cost-effective approach. When the joist framing is exposed during deck construction, panel attachment is straightforward, and gutter routing can be planned as part of the overall deck drainage design.
We recommend discussing Under-decks panels at the free consultation for any new elevated deck installation in Oklahoma.
What ceiling colors are available?
Five standard colors are available: White, Wicker, Clay, Royal Brown, and Dark Bronze. Custom colors are also available for Oklahoma homeowners who want the ceiling to match a specific home exterior color precisely.
We bring color samples to the free consultation and can discuss custom color options at that time.
What does the 25-year Stay Dry warranty cover?
The 25-year Stay Dry product warranty covers the Under-decks panel system against water penetration through the installed panel ceiling. If water drips through the panel system during normal rain events within the warranty period, the product warranty covers the issue.
This warranty applies in addition to our two-year no-questions-asked labor warranty on the installation itself.
Can an outdoor kitchen be installed in the under-deck space?
Yes. The dry, protected space created by Under-decks panels is one of the most practical outdoor kitchen locations on an Oklahoma property. It is shaded from direct overhead sun by the deck above and protected from rain by the panel ceiling.
For homeowners planning both an Under-decks panel system and an outdoor kitchen, we discuss the layout and any electrical or gas routing requirements at the free consultation.
Can motorized screens be added to the open sides of the under-deck space?
Motorized retractable screens on the open sides of the under-deck space combine with under-deck panels overhead to create a fully enclosed and weatherproofed lower-level outdoor room. The motorized screens deploy on demand to block insects and reduce UV, and retract completely on good weather days.
This combination is popular for Oklahoma properties with large elevated decks where the under-deck space is large enough to serve as a primary outdoor living area.
Can a porch conversion be done in the under-deck space?
Porch conversion systems using Walls Under panels can be installed in under-deck spaces to enclose the sides with WeatherMaster vinyl windows or glass panels. This creates a fully enclosed and weatherproofed lower-level sunroom from the under-deck space.
The combination of Under-decks panels, overhead, and Walls Under side panels on the sides fully encloses the space without any new structural addition to the home.
