This approach incorporates wide, shallow channels designed to obstruct water before it accumulates.
Trench Drains: Ideal for big flat roofing systems, these systems typically feature grates to keep particles out while carrying water.
Catch Basins: Positioned strategically to gather rainwater and filter out debris.
5. Green Roofing Systems
These include greenery on rooftops that assist in water absorption and management.
Extensive Green Roofs: Lower maintenance and need less soil depth.
Intensive Green Roofs: Require more maintenance with much deeper soil and a wider variety of plants.
