What Is The Function Of An Under Deck System?

Thanks to our patented, interlocking aluminum panels, Maxi Decks Protection creates a 100% watertight ceiling system that doesn’t just look seamless — it is.


Every panel is precision-engineered with a subtle slope, guiding rainwater effortlessly into a hidden gutter system. From there, it’s quietly channeled away from your deck, your foundation, and your peace of mind.


And while most imitators cut corners with cheap, sag-prone vinyl, we only use high-grade aluminum — built to last, built to perform, and built to protect what matters most.


No leaks. No drips. No compromises.

FUN Fact

How Much Clearance Is Needed Under The Deck?

At its highest point, the ceiling hangs just about 2 inches below your deck beams. From there, it slopes ever-so-slightly—just 1/8 inch for every foot—to ensure smooth drainage and flawless performance.



And here’s the best part…


In nearly every single install, there’s plenty of headroom left. Doors open fine. The space stays clean, dry, and totally usable—like an outdoor living room you’ll actually enjoy.


Now, in rare cases, a door might brush up against the system…

But don’t worry—we’ve already solved that. With a bit of expertly installed flashing, we’ve overcome this tiny hiccup every time. Fast. Easy. No stress for you.


Bottom line?


You get a sleek, waterproof ceiling below your deck—without sacrificing function or space.
