This technique incorporates large, shallow channels developed to intercept water before it builds up.

• Trench Drains: Ideal for big flat roofings, these systems typically include grates to keep particles out while funneling water.

• Capture Basins: Positioned strategically to collect rainwater and filter out particles.

5. Green Roofing Systems

These involve plant life on roofs that help in water absorption and management.

• Extensive Green Roofs: Lower maintenance and need less soil depth.

• Extensive Green Roofs: Require more upkeep with deeper soil and a larger variety of plants.

Key Materials for Roof Drainage

The materials used for roof drainage systems significantly affect their toughness and effectiveness.
