Custom Underdeck Ceiling Systems in Colorado

Bring Your Home Outdoors

A Dry, Beautiful Outdoor Living Space No Matter the Weather

Snowmelt and rain can turn the space beneath your deck into a wet, messy area—making it unusable for much of the year. At Undercover Systems of Colorado, we solve that problem with a patented underdeck ceiling system that creates a clean, dry, and beautiful outdoor living space beneath your existing deck.


Our custom underdeck solutions are crafted from heavy-gauge, galvanized steel to ensure long-term durability and protection. Each system is professionally installed by our experienced team, transforming what was once wasted space into a comfortable outdoor retreat—ready to enjoy year-round, rain or shine.


Backed by a lifetime transferable warranty, our ceiling systems are built to last, giving Colorado homeowners peace of mind and added value to their property.

Designed for Durability and Style

An elevated deck may offer a great view, but the space underneath often goes unused plagued by dripping water, stained concrete, and constant debris. Our underdeck ceiling system solves these problems and more by completely sealing off the underside of your deck with a sleek, waterproof ceiling.

Our system is:

Designed for Durability and Style

Unlike other underdeck systems that attach directly to your joists, our patented design suspends the ceiling panels below the joists, allowing air circulation and easy access for maintenance. This protects the integrity of your deck and prevents moisture buildup that can lead to rot or mold.


Our Clearspan System is load-tested and built to handle the state’s toughest snow and ice conditions—giving you a system that performs just as well as it looks.
