Rooftop decks showcase panoramic views and enhance outdoor living spaces. They add ambiance to our homes and provide opportunities to dine outside. Many times a rooftop veranda will expose views not previously available from inside the home. The extreme heights above grade that enable the spectacular views do require additional safety considerations. When dealing with rooftop deck safety, our concern is often largely geared towards the barrier railings. Barrier railing installations on roof decks pose a different set of considerations than ground level decks. In this article we will discuss some of these considerations and ways to mitigate any potential safety issues.
Safest Railings for Raised Decks
Whether you choose a traditional picket railing, glass panels, or one of the many other options available; a rooftop railing installation will be unique. Rooftop decks are almost always sloped and sloped deck railings require some custom considerations. So what are the most important things to consider when it comes to constructing rooftop deck railings? How should you mount your railings to a rooftop? Here are some common safety considerations for rooftop decks:
Slopes and Transitions-
Almost all roof decks are pitched in one or multiple directions. The ability to shed water is what basically defines a dry deck space. The amount of slope the deck requires will depend on the design parameters and the size of the deck. Some rooftop decks on flat roofs utilize drains or scuppers to direct water. In comparison; ground level decks are typically built level, which can be a much easier railing installation.
Rooftop deck railings often require the installer to adjust for slope and angles. Choosing to construct a sloped railing vs. a level railing is often overlooked. It can make all the difference in the finished product. Although a sloped railing is a possibility or even necessity in some cases, the level rail option is almost always preferred over a sloped railing. In our experience the sight line usually starts high and moves downward, meaning the top rail will catch the first glance almost 100% of the time.
What Can Be Done About Perforations?
Rooftop deck safety also includes waterproofing. In most cases, waterproofing should be completed and cured prior to the railing installation. Unless the post bases are to be coated over during waterproofing; it is preferable to install them on a finished surface. Additionally, products like Jiffy Seal and other flashing options can be used under railing posts to protect waterproof membranes. Sealing around post bases and annual safety inspections can also be very beneficial.
Structural Considerations for Safe Deck Railings-
The safest deck railings are attached extremely well and protect persons and pets from falls. Attachment needs to be done by utilizing connections to structural members. Bolting into plywood sheeting alone is not acceptable, even if a deck is already constructed. Whether you are building a new deck or repairing an old deck, it’s important to add blocking at the post locations prior to waterproofing. A professional railing installer or contractor should be able to locate structural members and or isolate any issues with attachment prior to construction. Solid blocking or structural members must offer at least 3″ of embedment for bolts attaching railing frames.
