Types of Roof Drainage Systems
Numerous approaches can be used to guarantee reliable roof drainage. The most common types include:
1. Gravity Drainage
This method makes use of gravity to direct water far from the roof surface.

Internal Drains: Located within the structure's structure, these drains pipes usage piping systems to remove water directly to the ground or the structure's drainage system.

Roof Drainage Leaders: These are vertical pipelines used to bring rainwater from the roof to the ground.
2. Slope Drainage
Creating slopes in the roof structure ensures water streams towards designated drainage points.

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

Enhanced Slope Systems: These often feature structured designs to improve water flow performance.
3. Gutter Systems
Gutters collect water that runs the roof edges, directing it safely away.

K-Style Gutters: Popularly utilized due to their aesthetic and functional advantages.

Half-Round Gutters: Known for their classic look and effective water flow.
4. Trough Drainage
This technique includes wide, shallow channels developed to intercept water before it collects.

Trench Drains: Ideal for large flat roofings, these systems often feature grates to keep particles out while channeling water.

Capture Basins: Positioned tactically to gather rainwater and filter out particles.
5. Green Roofing Systems
These involve plants on rooftops that assist in water absorption and management.

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

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