Nobody wants a storage box full of essential gardening tools, cushions, toys and so on. And whilst the vast majority of outdoor storage boxes sold by retailers are water-resistant, waterproofing is hard to guarantee. However, many of our BillyOh wooden storage sheds come with options for things like more heavy-duty waterproof roofing and thicker flooring to protect even further against damp. The interlocking panels of our metal and plastic sheds also protect them against even the harshest weather elements and water ingress.
