Kinds Of Roof Drainage Systems
Numerous techniques can be employed to ensure efficient roof drainage. The most common types include:
1. Gravity Drainage
This approach uses gravity to direct water far from the roof surface.

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

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

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

Enhanced Slope Systems: These typically include structured styles to enhance water flow performance.
3. Gutter Systems
Gutters gather water that runs off the roof edges, directing it safely away.

K-Style Gutters: Popularly utilized due to their visual and practical benefits.

Half-Round Gutters: Known for their timeless look and efficient water circulation.
4. Trough Drainage
This method integrates broad, shallow channels designed to intercept water before it collects.

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

Capture Basins: Positioned tactically to gather rainwater and filter out debris.
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 range of plants.
