That's an excellent and very practical question! A windy rooftop terrace can turn a standard trash bin into a flying hazard or a mess-maker. After dealing with this myself, I've found the best bins share a few key features to combat the wind.
First, look for heavy-duty materials. Plastic is common, but for high winds, opt for a thick, commercial-grade polymer or, even better, powder-coated steel. The extra weight is your friend. Some bins come with a weighted base or a sandbag ring you can fill for added stability.
The lid is crucial. A secure, locking lid or a tight-fitting flip-top is non-negotiable. Avoid simple swing lids that can flap open. Look for designs where the lid locks onto the bin body or has a sturdy hinge mechanism. A pedal-operated bin is a great choice here, as it keeps the lid securely closed until you step on it.
Anchoring options are a game-changer. The best bins for this environment have anchor points or holes in the base allowing you to use bungee cords, ratchet straps, or brackets to secure it to a railing or wall. If that's not possible, placing it in a sheltered corner, away from the prevailing wind, helps.
For style and function, consider a rectangular design—it's less likely to roll and can fit snugly into corners. A built-in ashtray can be useful if you entertain. My top recommendation would be a heavy, rectangular steel bin with a locking pedal lid and anchor points. Brands like Simplehuman or commercial lines from Rubbermaid often have models that fit this bill perfectly. It might be a bigger investment, but it will save you from chasing trash across the terrace!
