Question

In 3–5 sentences, explain the various factors that should be considered when implementing green roofs.(4 points)

Answer 1

When implementing green roofs you must first confirm the building’s structural capacity and provide safe access for installation and ongoing maintenance, accounting for dead/live loads, snow and wind. The roof assembly needs an appropriate waterproofing membrane, root barrier, drainage layer, filter fabric and a substrate depth chosen for the intended plant community and thermal/insulation goals. Plant selection should match the local climate and maintenance expectations (drought-tolerant species for extensive roofs, deeper substrates for intensive plantings), and you must plan irrigation, erosion control and routine upkeep. Finally, consider life-cycle costs, warranties, local codes and permitting, plus the project’s stormwater, energy and biodiversity objectives when evaluating feasibility.
