Types of Roof Drainage Systems
Numerous methods can be employed to ensure effective roof drainage. The most typical types consist of:
1. Gravity Drainage
This technique utilizes gravity to direct water away from the roof surface area.

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

Roof Drainage Leaders: These are vertical pipes used to carry rainwater from the roof to the ground.
2. Slope Drainage
Creating slopes in the roof structure makes sure water streams towards designated drainage points.

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

Improved Slope Systems: These typically feature structured designs to improve water circulation effectiveness.
3. Gutter Systems
Gutters gather water that runs the roof edges, directing it securely away.

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

Half-Round Gutters: Known for their classic look and efficient water flow.

This method includes large, shallow channels created to intercept water before it collects.

Trench Drains: Ideal for big flat roofing systems, these systems often include 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 plant life on roofs that assist in water absorption and management.

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

Intensive Green Roofs: Require more maintenance with deeper soil and a wider variety of plants.
