1. Structural Considerations: Green roofs can be heavy, so the structure of the home must be able to support the weight of the soil, plants, and any additional components.
2. Waterproofing: The green roof system must have proper waterproofing to prevent leaks and protect the structure from moisture damage.
3. Insulation: Proper insulation must be installed in order to increase energy efficiency and reduce heating and cooling costs.
4. Plant Selection: The type of plants that are used on a green roof will greatly affect its performance. The plants must be carefully selected to thrive in the local climate, and they should be able to withstand harsh weather conditions.
5. Drainage: Adequate drainage is essential for the health of the plants on a green roof and to prevent water damage to the structure. Drainage systems must be designed to handle fluctuations in rainfall and prevent standing water.
6. Maintenance: Green roofs require regular maintenance to ensure that they continue to perform at their best. Considerations must be made for access to the roof, irrigation systems, and ongoing gardening tasks.
7. Sun and Wind Exposure: The orientation of the home and roof, as well as the degree of exposure to sun and wind, is an important consideration for the design of a green roof. The level of exposure will determine which plants will thrive and how much irrigation will be needed.
8. Aesthetics: The design of a green roof can greatly impact the overall aesthetics of a home. Considerations must be made for the color and texture of the plants, as well as the placement of any additional features such as garden beds or seating areas.
