This approach utilizes gravity to direct water away from the roof surface.

Internal Drains: Located within the structure's structure, these drains pipes use piping systems to get rid of water straight to the ground or the structure's drainage system.

Roof Drainage Leaders: These are vertical pipelines utilized to carry rainwater from the roof to the ground.
2. Slope Drainage
Developing slopes in the roof structure guarantees water flows towards designated drainage points.

Positive Drainage: A pitch or slope directs water to specific drains or ambushes.

Enhanced Slope Systems: These often include structured styles to enhance water circulation efficiency.
3. Gutter Systems
Gutters gather water that runs off the roof edges, directing it securely away.

K-Style Gutters: Popularly used due to their aesthetic and functional benefits.

Half-Round Gutters: Known for their classic look and effective water flow.
4. Trough Drainage
This approach includes large, shallow channels designed to obstruct water before it collects.

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

Capture Basins: Positioned strategically to gather rainwater and filter out particles.
5. Green Roofing Systems
These include greenery on roofs that assist in water absorption and management.

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

Extensive Green Roofs: Require more upkeep with deeper soil and a wider range of plants.
Key Materials for Roof Drainage
The materials utilized for roof drainage systems significantly impact their resilience and effectiveness.
