The short answer
A terrace garden is safe when three things are checked first: how much weight the roof can carry, how water drains away, and the condition of the waterproofing. Wet soil is heavy, so the design must match the roof. When these are right, a terrace garden protects the roof from direct sun.
What to check
- 01
Check the weight
Wet soil and large planters are heavy. Match the design to the roof.
- 02
Check drainage
Water must flow to the drains, not sit on the roof.
- 03
Check waterproofing
Fix any weak spots before building.
- 04
Choose light options
Pots, planters and turf weigh less than deep beds.
