Implementing reliable membrane or coating solutions to protect the building.

"You’re absolutely right—a constantly wet bottom is the ultimate test of poor engineering prevalent all around, and leaky roofs are proof!

This is why you must adopt a three-pronged defense. First, the foundation: you still need that good quality, durable membrane or coating as your non-negotiable insurance. Second, the Smart Fix: Don't rely on the roof being perfect! Get your containers, bags, and pots up off the surface! Even a small stand or brick creates a tiny air gap. Why? Because the continuous air blow beneath your pots keeps the roof surface permanently dry, eliminating that continuous saturation risk. Third, Farmer’s Discipline: Practice regular movement—keep shifting those bags and pots from one spot to another.

This proactive, dual strategy—Air Gap + Rotation—is the smartest way to ensure you enjoy your garden without ever having to apologize to your downstairs neighbors!"
