Gutters collect water that runs off the roof edges, directing it securely away.

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

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

Trench Drains: Ideal for big flat roofings, these systems often feature grates to keep particles out while directing water.

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

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

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