FAQ
Frequently Asked Questions
Not exactly. A 'green roof' is primarily an ecological building element for insulation and water management, often with low-maintenance, shallow planting. A 'roof garden' is designed for human access, recreation, or agriculture, with deeper soil and diverse plantings.
No. The roof must be flat or gently sloped, structurally reinforced to hold the significant weight of soil, plants, water, and people, and have proper waterproofing and drainage systems.
Plants must tolerate wind, sun, and sometimes shallow soil. Common choices include sedums, herbs (lavender, thyme), ornamental grasses, succulents, and small, hardy shrubs. For deeper soil, vegetables and perennials are possible.
Benefits are multifold: they provide recreational/green space in dense cities, reduce the 'urban heat island' effect, improve building insulation, manage stormwater runoff, and can support local biodiversity or food production.
