Roof Terrace Planter FAQs

On a roof terrace, every kilogram counts. Planters, soil and water all add to the structural load, which is why weight is so often a deciding factor in roof garden design. Aluminium offers an excellent strength-to-weight ratio compared with heavier materials such as concrete, so you can plant generously without adding unnecessary load.



Your structural engineer will confirm what the roof can carry; our job is to make sure the planters themselves add as little as possible. Monarch manufactures bespoke aluminium planters for roof terraces of all sizes, from private residential terraces to large commercial roof gardens. Read on for answers to the most common questions.
