Gutters gather water that runs off the roof edges, directing it safely away.

K-Style Gutters: Popularly used due to their visual and functional benefits.

Half-Round Gutters: Known for their classic look and efficient water flow.
4. Trough Drainage
This approach incorporates large, shallow channels created to intercept water before it collects.

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

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

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

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