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

Half-Round Gutters: Known for their classic look and effective water flow.
4. Trough Drainage
This approach integrates large, shallow channels developed to obstruct water before it accumulates.

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

Capture Basins: Positioned strategically to collect rainwater and filter out debris.
5. Green Roofing Systems
These include vegetation on rooftops that assist in water absorption and management.

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

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