Custom Underdeck Ceiling Systems Bring Your Home Outdoors
For over two decades, we have been transforming the forgotten space beneath upper-level decks into stunning outdoor living rooms. Proprietary galvanized steel construction. Lifetime warranty. Designed, fabricated, and installed by Colorado natives who take personal ownership of every project.
We Did Not Start a Business. We Built a Trade.
Undercover Systems of Colorado was not born in a boardroom. It started on a job site in Wheat Ridge over twenty years ago, when our founder saw an industry cutting corners with flimsy aluminum panels and one-size-fits-all designs. He knew Colorado homeowners deserved better. So he built something better.
Today, we are an employee-owned company. That means every single person who shows up to your project has a personal stake in the outcome. There are no subcontractors, no franchise playbooks, and no pressure sales. Just experienced Colorado craftsmen who designed their own proprietary galvanized steel panel system and have spent two decades perfecting the installation process in the most demanding climate in the country.
We stand behind our work with a lifetime warranty because we have never had a system fail. When you work with us, you are not hiring a company. You are partnering with a team of owners who care about your home as much as you do.
Under Decking Ceiling Systems
Our signature service and the reason we exist. We install custom-engineered galvanized steel ceiling systems beneath upper-level decks that transform dead space into dry, beautiful outdoor rooms. Each panel is precision-cut to fit your deck’s exact dimensions. Integrated drainage channels capture every drop of rainwater and route it silently away from your living area. The result is a weather-protected outdoor room that looks and feels like a natural extension of your home, not an afterthought bolted to the bottom of your deck. This is the system we designed from scratch over 22 years ago, and it is still the strongest, most reliable underdeck ceiling on the market.

Under Decking Pergolas
Combine the weather protection of our underdeck ceiling with the architectural elegance of a custom pergola. Galvanized steel framing with design options that match your home perfectly. The pergola extends your covered area beyond the footprint of your deck, creating shade and structure for outdoor dining, lounging, or entertaining.

Precision Fabrication
Every panel is cut, formed, and finished in our Wheat Ridge facility. We do not use off-the-shelf parts or outsource fabrication. Each component is made specifically for your project, from the ceiling panels to the drainage channels to the trim pieces.
Expert Installation
Our employee-owners install your system in two to four days. Every installer has a personal stake in the quality of the work. We leave your property cleaner than we found it, walk you through your new system, and hand you a lifetime warranty that we have been honoring for over two decades.
Most underdeck companies use aluminum panels because they are cheaper and easier to install. We chose galvanized steel over twenty years ago because we knew it would outlast every alternative on the market. Our proprietary panel design channels water efficiently, resists Colorado’s extreme temperature swings from summer heat to heavy mountain snow loads, and maintains its structural integrity for decades without warping, cracking, or fading.
As an employee-owned company, every team member has a personal stake in the quality of every installation. When we say lifetime warranty, we mean it because our reputation is our livelihood. We are Colorado craftsmen who designed, tested, and perfected our own system right here on the Front Range.

Call (303) 481-1967 →We interviewed several underdeck companies and Undercover Systems stood apart from day one. The attention to detail, the quality of their steel panels, and the fact that every person on the crew was an owner in the company gave us complete confidence. Two years later, our outdoor space still looks brand new through brutal Colorado winters. We use it every single day from April through October now.Colorado HomeownerCastle Rock, CO
Our deck sits twelve feet off the ground and the space underneath was completely unusable. Undercover Systems turned it into a second living room. The drainage system works flawlessly through heavy rain and the ceiling panels look like they were always part of the house. Our neighbors have all asked who did the work, and we have already referred three families. The craftsmanship is that noticeable.Colorado HomeownerHighlands Ranch, CO
