How to Buy a Wood Rooftop Deck You Will Love

Written by on

A rooftop deck adds enjoyment to your life and value to your home or property. If you are dreaming of adding a rooftop deck to your home, do your homework first. Avoid regrets by planning properly. A well-built and long-lasting roof deck can pay for itself. See how.


If you have a flat roof, and you are currently wasting the space, a rooftop deck can give you a brand-new room. An outdoor penthouse amenity. Great views, great fun, great memories. The only other way to add more square footage of living space to your home is to build an addition. And they can be very pricey.

The Financial Case for a Rooftop Deck

Every year real estate studies report that kitchens and outdoor decks are the top two improvement projects with the best return. A new kitchen or a backyard deck typically return about 80% of their costs to the added value of the home. Even better, a rooftop deck often returns up to 150% of the initial investment cost.

Now that’s a very nice return on your investment! You get to use your rooftop deck the entire time until you eventually sell your home. Then, when you sell your home, you can cash in on your investment. If you have the cash or funding available to invest in a rooftop deck, you get a double benefit.

Look at a high-quality rooftop deck with a Eurotec aluminum joist and pedestal frame system with hardwood decking. Depending on your size, materials and other factors, this type of long lasting and durable roof deck will cost in the vicinity of $25 to $35 per square foot for materials.

Compare the initial cost and return on investment of a home addition to a rooftop deck. A typical addition project runs in the $200 to $250 per square foot range. Often even higher. When you compare the cost of an addition to a roof deck, it’s not even close. You could buy 5 to ten rooftop decks for the price of one addition.

And here’s the kicker. The return on invest for a new home addition is usually in the 70% range. I’m not saying an addition is a bad investment. Home additions are wonderful. They provide lots more living space, more functionality for your home, you get most of your investment back when you sell, etc. But compared to the likely 150% return on investment of a roof deck, the deck provides a much better return on your investment.

Making Your Rooftop Deck Budget Work

First, establish a budget for your deck. Take your budget and divide it by the square footage of deck you’d like to build. That is your cost per square foot for your deck.


Here’s one example of a preliminary budget for a rooftop deck:

Let’s say you have a budget of $20,000 for materials and you’d like to build a 20 foot by 20-foot roof deck (400 square feet).

$20,000 divided by 400 equals $50 per square foot available for your roof deck materials. You can buy a lot of deck for $50 per square foot.  And if you don't need the full $50 per square foot, you can buy some furniture, planters or maybe add a pergola.

Here’s another rooftop deck budget example:

Let’s say you have a budget of $20,000 for deck materials. If you take your budget and divide it by $35 per square foot, you end up with 571 square feet. That’s roughly a 20 foot by 28-foot deck. So, if you need additional space, you could build an even larger deck with more space for various activities. And still stay on budget.

If you have a different rooftop deck budget and different square footages, calculate your numbers the same way. Don’t forget to budget for your labor costs and furnishings, too. See what works best for your budget and your project.


Rooftop Deck Proper Prior Planning

There are a lot of steps when you’re planning a rooftop deck project. The basic steps are checking with your local building inspectors and code officials to see if roof decks are allowed in your area. Then you will want an engineer to evaluate you existing roof to see if it can hold the additional weight of a deck. There are a few more, too. Don’t skip these important steps.
