This technique makes use of gravity to direct water far from the roof surface area.

Internal Drains: Located within the building's structure, these drains pipes usage piping systems to eliminate water straight to the ground or the building'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 guarantees water flows towards designated drainage points.

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

Boosted Slope Systems: These frequently feature structured designs to enhance water flow efficiency.
3. Gutter System Systems
Gutters collect water that runs the roof edges, directing it securely away.

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

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

This method incorporates wide, shallow channels created to obstruct water before it builds up.

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

Catch Basins: Positioned tactically to collect rainwater and filter out particles.
5. Green Roofing Systems
These include vegetation on roofs that assist in water absorption and management.

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

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