Challenge yourself by building a floating deck on top of your flat roof. Most roofs are flat and after finding the right deck design that does not need a frame in order to support the decking, it is possible to create a comfortable space for relaxing, eating and entertainment.

How to Build a Deck Over a Flat Roof
If you have a flat roof, you can add more living space and value to your home by installing a deck. There are several methods of building decks over flat roofs, but the most common is using the floating deck system.
Floating Deck System
The floating deck system uses joists that are attached to the inside of the roof sheathing by metal clips or brackets. The joists are then attached to each other at the ends with metal hangers or hanger straps. The joists support the decking boards and create an even surface for walking on. The boards can be made from any type of material that suits your needs and budget, including wood, composite or pressure-treated lumber.
Building a deck on top of your flat roof is not as difficult as it might sound. It does require some careful planning and the right materials, but the result will be a safe, sturdy and beautiful outdoor space for entertaining or relaxing.
Your first step is to draw up plans for your deck. You will want to include stairs and railings in your design. You can also add lighting fixtures and ceiling fans if desired. Once you have drawn up your plans, take them to a contractor or building supply store so they can tell you what materials you need and how much material it will take to complete the project.
Building a deck on a flat roof can be a little tricky. But with the right tools and materials, you can get the job done in no time.
Start by measuring your roof and sketching out your deck design. Then, decide how to frame the deck. You’ll want to make sure that you frame it so that it’s strong enough to hold the weight of whatever you plan on putting up there.
Next, build your frame and attach it to the house with screws or bolts and some extra framing material like 2x4s or 2x6s. You’ll need to do this step before attaching any of your decking materials because it will help support them later on in the process.
Once your frame is built, add some plywood over top of it so that it’s flush with the flat surface of your roof. This will help create a smooth surface for laying down your flooring materials like carpet or wood slats (which should be treated first). Make sure not to nail through any shingles into this plywood sheet though!
A flat roof is the perfect place for a deck. You can build a deck over just about any type of flat, pitched or sloped roof. The only limitation is your imagination.
Floating decks are built on top of the ground and cantilever out over the edge of the building’s surface. They are ideal for flat roofs because they allow you to have outdoor living space without sacrificing valuable square footage inside your home.
A floating deck is similar to an angled deck in that it uses support posts that attach to an existing wall or railing. But instead of angling them out, they extend straight out from the house to provide support for your decking material.
There are several advantages to floating decks:
They are less expensive than other options because they don’t require building foundations or adding height to your structure;
They take up less room inside your home than other options like raised decks do;
Floating decks can be installed on existing structures such as existing walls or railings;
A flat roof deck is a great addition to a home, but it can be difficult to build. When the roof is flat, you don’t have the normal support of rafters or joists to build your deck on top of. Instead, you’ll need to construct a frame that will support both your decking and your weight.
The first step in building a flat roof deck is framing out the area for the deck itself. You’ll want to use either 2×4 or 2×6 lumber for this part of the project. Locate the center of your roof and mark off where each end of the deck will be located along with any posts or beams you may want in between them.
Once you’ve determined these locations, nail together four large blocks of wood at each corner using two 2x4s or two 2x6s. This will create a square shape for your roof support structure that will allow it to rest safely on top of the roof without sinking into it too much.
Next, add another row of boards over each side of your square frame so that they meet in the middle at right angles to each other. This creates a basic platform on which you can build whatever type of flooring you want (perhaps just some gravel).
