Trench Drains: Ideal for big flat roofings, these systems often include grates to keep debris out while carrying water.

Capture Basins: Positioned tactically to gather rainwater and filter out particles.
5. Green Roofing Systems
These include plant life on rooftops that help in water absorption and management.

Comprehensive Green Roofs: Lower maintenance and require less soil depth.

Extensive Green Roofs: Require more upkeep with much deeper soil and a larger range of plants.
Secret Materials for Roof Drainage
