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

K-Style Gutters: Popularly utilized due to their visual and functional advantages.

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

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

Catch Basins: Positioned tactically to collect rainwater and filter out debris.
5. Green Roofing Systems
These include greenery on roofs 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 wider variety of plants.
