An under deck ceiling that works
Create a beautiful new outdoor living space.
The ceiling collects rainwater that falls between your deck boards, directs it into a gutter and downspout, and leaves a clean, dry space below without exposed nails, dirty rafters, or water hazards.

The Under Deck Oasis advantage
Compared with vinyl and PVC ceilings
Rigid aluminum holds its shape.
Vinyl systems rely on polymer panels that can feel flexible by design. Under Deck Oasis uses high-quality aluminum for a firm, architectural ceiling.
The alternative
Flexible vinyl or PVC components can be more susceptible to movement as outdoor conditions change.
Under Deck Oasis
Rigid aluminum is selected for long-term exterior performance without the sagging, splitting, or rust concerns associated with lesser materials.
The Under Deck Oasis advantage
Compared with above-joist membranes
Add the system without rebuilding the deck.
Above-joist membranes are placed over the joists before the decking goes down. Retrofitting one later can require removing existing deck boards.
The alternative
The drainage layer is integrated into the deck build, making installation timing and access from above important.
Under Deck Oasis
The system is installed beneath the joists of a compatible existing deck, allowing the deck surface above to remain in place.
The Under Deck Oasis advantage
Compared with limited-finish systems
Design a ceiling that belongs with the home.
Some common vinyl systems are offered in only white and bone, limiting how the finished ceiling can relate to the rest of the outdoor room.
The alternative
A narrow palette can make the ceiling feel like a utility product instead of part of the architecture.
Under Deck Oasis
Choose from eight solid colors, five woodgrain finishes, and smooth or rustic panel textures. Panels and trim can also be coordinated separately.
The Under Deck Oasis advantage
Compared with standardized kits
Plan around the deck, not the box.
Real decks include beams, cantilevers, stairs, doors, drainage constraints, and accessory locations that do not always fit a standardized layout.
The alternative
Fixed lengths, standard spans, and limited components can place more of the burden on the deck to fit the system.
Under Deck Oasis
Each layout is reviewed for the actual structure and professionally planned around drainage, clearances, fans, lighting, heaters, and finished details.
The service advantage
Compared with product-only systems
The system comes with a team.
Buying drainage materials is not the same as having the deck reviewed, the installation planned, and experienced people available before and after the project.
Materials alone
The homeowner or contractor may be left to coordinate deck conditions, drainage, accessories, installation quality, and future service separately.
Under Deck Oasis
The Grandville team supports project planning, traveling crews serve projects nationwide, and a growing dealer and certified-installer network extends trained installation and local support.
The coverage advantage
Compared with material-only protection
Product coverage is only half the story.
Material warranties and installation workmanship warranties protect different parts of a project. Some product warranties exclude improper installation along with associated labor or removal costs.
Material-only coverage
A product warranty may address manufacturing defects while leaving installation workmanship and related service to a separate contractor.
Under Deck Oasis
Qualifying Under Deck Oasis installations include a five-year workmanship and no-leak installation warranty, with aluminum materials covered separately under the manufacturer’s limited lifetime warranty. Terms and exclusions apply.
Every deck is different. Final compatibility, clearance, drainage, accessories, and installation details are confirmed during project review.

How the under deck ceiling works
A waterproofing ceiling attached beneath your deck.
The interlocking aluminum panels collect rainwater, then use a slight pitch to move it into a gutter. A downspout carries the water to a controlled location away from the deck.
- Seamless, watertight interlocking aluminum panels
- Approximately 2-3 inches below the joists at the high end
- A 1/8-inch-per-foot slope moves water toward the gutter
- Compatible with lights, ceiling fans, and other accessories
The best color and finish options
Match your home. Make the space yours.
Choose from eight solid colors and five unique woodgrains, then add the optional rustic texture for even more depth. Our finishing process is designed to resist fading, and panels and trim can be mixed for a custom combination.

How is Under Deck Oasis purchased and installed?
Start with a free project estimate. Our team will plan the system for your deck and coordinate professional installation through an Under Deck Oasis crew or a trained installer serving your area.
How much does the system cost?
Pricing depends on deck size and shape, finish, location, cantilever areas, fans, lighting, accessories, and installation complexity. The estimate form gives our team what they need to prepare an accurate quote.
When it rains, where does the water go?
The panels act like a large trough beneath the deck. Their slight slope moves collected rainwater into a gutter, which sends it through a downspout and away from the deck and house.
How does the system handle snow and wind?
The sturdy aluminum system was designed in Michigan for harsh Michigan winters. Each panel locks securely into the teeth of the carrier system, helping keep the ceiling firmly in place during heavy snow and strong winds.
Can I add lights, fans, and other accessories?
Yes. Under Deck Oasis regularly plans for ceiling fans, lights, heaters, and other accessories while properly diverting water around their mounting areas.
What warranty protection is available?
Under Deck Oasis provides separate installation and manufacturer material warranties. The full warranty documents explain coverage, service requests, material claims, and the disclosure for homes near salt water.
