Internal Drains: Located within the building's structure, these drains use piping systems to remove water directly 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
Developing slopes in the roof structure makes sure water streams towards designated drainage points.

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

Improved Slope Systems: These frequently 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 used due to their aesthetic and practical benefits.

Half-Round Gutters: Known for their classic look and efficient water flow.
4. Trough Drainage
This method includes broad, shallow channels created to intercept water before it accumulates.

Trench Drains: Ideal for big flat roofs, these systems frequently include grates to keep particles out while directing water.

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

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

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