Having a rooftop garden is a wonderful way to enjoy urban outdoor space. A common concern for owners is whether the legs of urban outdoor furniture will damage the critical waterproof membrane below. The direct answer is: yes, they potentially can. Point loads from sharp or narrow furniture legs, constant pressure, and movement can puncture or wear down the membrane over time, leading to costly leaks.
To prevent this, consider these essential protective measures. First, always use wide, flat furniture feet or legs to distribute weight evenly. Second, and most importantly, place protective pads or mats under each leg. These can be rubber pads, PVC mats, or specially designed composite decking tiles that create a barrier. Avoid dragging furniture, and consider using lightweight materials. Regularly inspect the area under your furniture for signs of wear. By taking these simple precautions, you can safeguard your waterproofing investment and enjoy your rooftop oasis with peace of mind, ensuring your garden remains a source of joy, not water damage.
