Deck Over A Flat Roof

There are proprietary pedestal systems that provide a very stable, level and serviceable deck over a roof membrane, though, they are relatively expensive compared to conventional methods.

In whatever manner a deck is constructed over a roof, maintenance for cleaning and repairs of the membrane below is recommended. Deck panels should be constructed that can be lifted with minimal effort or damage. The roof below should be cleaned and inspected at whatever intervals is found necessary for each deck. A deck located under pine trees will need much more maintenance to clean out debris than a rooftop deck above a high-rise.

Flat roofs are prone to leaking even without decks because of design errors, improper materials and improper installation. Many times when roof decks are installed, they further damage roofs causing more severe leaking and drainage problems. Proper waterproofing for a roof deck involves installing an EPDM membrane and flashing around deck supports and rail penetrations. This is often accomplished using EPDM boots that fit over the openings. EPDM is a rubber like sheet used for waterproofing surfaces. Roofs should be sloped about 1/4″ every 12″ to shed water. Drainage is very important because pooling water can cause leaks.

Access Points For Your Rooftop Deck

Access points, or means of egress, are the ways people can enter and exit the roof deck. Boston has strict building code for means of egress because they are critical for making the deck as safe as possible in the event of an emergency. How many access points you’ll need on your deck depends on who will be using the deck. There are two types of use: community decks and single owner decks.

Build Your Deck’s Substructure

Installing Flat Roof Deck

Now that your flat roof has either been replaced or confirmed to be free of issues, it’s time to build the structural base for your new outdoor living space!

The deck’s “substructure” consists of everything that holds the roof deck together including the posts, rafters, hangers, and framing. These elements are critical to the project because they provide the backbone of what the deck itself will sit on.

Exact materials vary from project to project, however, two most common materials we use to create a roof deck substructure are pressure-treated wood and steel beams. If the building’s roof is not completely flat, steel beams may be required in order to create a flat, level surface that will be safe enough to use as a base for the deck flooring. Another reason steel beams may be used to frame the roof deck is occupancy limits. The code for this is 300 pounds per square foot.

Unless local code or the roof’s shape necessitates the use of steel, most homeowners are fine with a wood substructure in order to save on cost.

Roof Is Able To Support Adequate Weight

Determining how much weight your roof can support is a job that should be left to a professional engineer or architect. Miscalculating the strength of your roof can result in grave damage and even death.While local building codes vary from state to state, the minimum requirements typically state that your roof needs to support at least 55 pounds of weight per square foot.

However, the necessary strength of your roof will also vary depending on how you plan to use the rooftop deck. For instance, if you plan to add a hot tub or other heavy furniture, you will need to account for the added weight in the design of your rooftop deck.

Even if your current roof is not strong enough to support the additional weight of a rooftop deck, there may be ways to strengthen the existing structure. You can read more about how to reinforce your roof strength here.

Composite Roof Deck Materials

If you can budget for it, you’ll likely be very happy that you chose composite decking for your rooftop patio. The most notable downside is that it’s a higher upfront cost than wood, but many homeowners feel that this levels out after a few years because of it’s benefits.

The #1 reason everyone loves composite decking is that it’s almost completely maintenance-free. If you don’t want to spend a weekend staining your deck every year or two, then choose composite. Lifespan is another significant upside, especially for your Boston-area deck that will experience more moisture and temperature swings than other regions across the United States. With composite, you won’t have to worry about wood rot.

Popular brands for composite roof deck material include Azek, Trex, and Fiberon. We almost exclusively use Fiberon because we’ve found that it’s the industry’s best value and offers impressive longevity. Your deck’s ability to stand up to Massachusetts weather for years to come should be considered during all phases of your project. And when it comes to deck material, we think you’ll agree that Fiberon’s slogan “Deck it right the first time” says it all!
