This technique includes large, shallow channels designed to obstruct water before it accumulates.

• Trench Drains: Ideal for big flat roofs, these systems often feature grates to keep particles out while transporting water.

• Catch Basins: Positioned tactically to collect rainwater and filter out particles.

5. Green Roofing Systems

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

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

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

Key Materials for Roof Drainage

The materials used for roof drainage systems considerably affect their sturdiness and effectiveness.

Best Practices for Roof Drainage
