Creating a cozy outdoor oasis on your urban rooftop is a fantastic way to maximize space and enjoy the skyline. However, high winds can turn your stylish furniture into dangerous projectiles. Securely anchoring your pieces is essential for safety and longevity. Here’s a practical guide on how to anchor down your urban outdoor furniture on a rooftop.
First, assess your furniture and rooftop surface. Check if your furniture has pre-drilled holes for anchoring or built-in eyelets. Identify your rooftop material—is it concrete, wood decking, or a protective membrane? This will determine the best fastening methods. Avoid any technique that punctures a waterproof membrane unless done by a professional.
One of the simplest solutions is to add weight. For lighter items like side tables and chairs, use furniture with built-in weight, such as concrete-topped tables. You can also create DIY weight bags filled with sand or purchase weighted bases designed for umbrella stands and furniture legs. This method is non-invasive and ideal for temporary setups.
For a more permanent and secure solution, use straps and tie-downs. Heavy-duty straps, similar to those used for truck cargo, can be looped around furniture frames and anchored to robust, fixed points on the rooftop, like a sturdy parapet wall or dedicated anchor points installed by a contractor. Ensure the straps are UV-resistant to withstand sun exposure.
Another effective method is to use ground anchors or foot plates. For furniture with legs, you can screw foot plates directly into a wooden deck. On concrete, use concrete screws and anchors. You can then use zip ties, metal brackets, or cables to attach the furniture legs to these secured plates. This provides a very strong, low-profile hold.
Finally, think about your overall layout. Positioning heavier, more wind-resistant pieces like solid sofas on the windward side can act as a buffer for lighter items. When severe weather is forecast, the safest practice is to always store lightweight cushions and portable furniture indoors. By taking these steps, you can create a secure, stylish, and enjoyable rooftop retreat that stands up to the elements.
