Quality Materials

Each system is custom designed and manufactured from heavy gauge, galvanized steel. The ceiling comes in multiple colors to match your home’s aesthetic.



Take your space to the next level by adding accessory items like ceiling fans, recessed can lights, speakers, porch swings and more. The space can even be enclosed for a screened porch or a fully framed enclosure. The possibilities are endless.

Why Choose Us

Our Satisfied Customers

This is a game changer for us. This space which couldn’t be used for days after a rain due to wet furniture is now usable anytime. Plus we can store stuff here during a rain. The fans help air flow as well where it can get super stuffy on those hot summer days. Super pumped for the first time it rains o I can just sit there and be dry!!!!


Sioux Falls

We absolutely love the system that Undercover Heartland put under our deck. We have a hot tub under there and now are able to use it year round without rain or snow falling on us. It’s also nice to have some protected shade in the summer that stays clean and covered. It feels like we added another room to our house for way less money. They did a great job, were very clean and organized as well.


Sioux Falls

We had an Undercover Heartland system installed this summer (2023). We just love it! It looks so beautiful and gives our patio such a nice finished look. It doubled our outdoor living space! Our outdoor furniture stays nice and dry and clean.  The staff was very professional and friendly. They answered all our questions. They did a great job!


Rapid City

Jon and Erica are wonderful people to work with They always call before they come to job site. Do a wonderful job, love my new deck and would love to work with these two again.



We give this product 5 stars out of 5.  Very professional looking, does what it said to do, keeps the water out of the lower deck.  The owners of this business are top notch, showed up when they said, worked through the rain and storms.  Right after they completed the job, we had the worst rain storm in decades, flooded our yard, and there was not a drop of water under the ceiling.  We give them the highest recommendation possible.  They make a great team.



Amazing Craftsmanship! I highly suggest this company and will surely use them again on future projects.
