In 3–5 sentences, explain the various factors that should be considered when implementing green roofs

When implementing green roofs, several factors should be considered. Firstly, the structural integrity of the building must be assessed to ensure it can support the weight of the green roof. Additionally, the climate of the region and the amount of sunlight the roof receives should be taken into account to determine what types of plants will thrive. Proper drainage systems need to be in place to prevent water damage and ensure the longevity of the roof. Maintenance requirements, such as watering and pruning, should also be considered to ensure the green roof remains healthy and attractive.
