Your Roof Is a Deck: The Rooftop Living Space on Every Arena Home
Look up at almost any house and you'll see a triangle of wasted space — an attic nobody uses under a roof that only sheds rain. Arena treats the roof as what it could be: a floor. Every Arena home is built with a warm, flat, protected roof engineered as real outdoor living space — a second backyard, up top, with the Wasatch in every direction.
A dead attic, or a second backyard?
A conventional pitched roof does one job — keep the water out — and buries a third of your home's footprint in unusable attic. Flip that roof flat, build it to be walked on, and you've added hundreds of square feet of the most valuable space a Utah home can have: private outdoor room with a view, on land you already own, with no extra lot to buy.
How a "warm roof" makes it usable
The trick is the assembly. A standard flat roof bakes its waterproof membrane in the sun and foot traffic until it fails. Arena builds a protected (inverted) roof: the insulation and the walking surface sit on top of the membrane, so the part that keeps water out is shielded from sun, temperature swings, and footsteps — and lasts far longer.
Protected membrane
The waterproofing lives under the insulation, shielded from UV and foot traffic — the failure mode of ordinary flat roofs, designed out.
Pedestal pavers
Level pavers sit on adjustable pedestals with an air gap beneath, so the surface drains freely, dries fast, and shrugs off Utah's freeze-thaw.
Engineered for Utah loads
The steel structure is sized for snow load plus people — the roof-deck structural calc is done up front, not bolted on later.
Interior stair access
You reach it from inside, up the same steel stair that runs the height of the house — not a ladder and a hatch.
What you'll actually do up there
An evening lounge above the neighborhood. A container garden that finally gets full sun. A little outdoor kitchen for summer. Room to watch the fireworks, the sunset over the valley, the mountains going pink in the morning. Hot-tub and sauna hookups can be provisioned in the build if you want them. It's the room people fall in love with — and it comes standard, not as a premium package.
The math: outdoor square footage, for a fraction of the cost
Here's why it's such a good deal. You're already paying for a roof. Building it to be lived on — instead of wasted — adds usable square footage at a small fraction of what indoor space costs per foot. It's the same logic behind the whole Arena Standard: spend where it changes how you live, and engineer it in from the start so it costs a fraction of indoor space. A rooftop deck bolted onto a finished conventional house is a five-figure renovation; on an Arena home, it's just how the roof was always built.
