Understanding the Basics of Green Roofs
What is a Green Roof?
A green roof is a roof partially or completely covered with vegetation. It includes a growing medium, such as soil, planted over a waterproofing membrane. Green roofs are designed to absorb rainwater, provide insulation, and create a habitat for wildlife.
Types of Green Roofs
- Extensive Green Roofs: These are lightweight and require minimal maintenance. They are often covered with drought-resistant plants like sedums.
- Intensive Green Roofs: These require more soil and can support a wider variety of plants, including trees and shrubs. They demand more attention and maintenance.
Importance of Regular Maintenance
Regular maintenance of a green roof ensures its health and functionality. Without proper care, a green roof can turn from an asset into a liability, with issues like plant mortality and water leakage.
Benefits of Maintenance
- Prolongs the lifespan of the roof.
- Maintains the aesthetic and environmental benefits.
- Prevents structural damage to the building.
