Gutters gather 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 timeless look and effective water flow.
4. Trough Drainage
This method incorporates broad, shallow channels created to obstruct water before it collects.

Trench Drains: Ideal for big flat roofings, these systems often include grates to keep debris out while carrying water.

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

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

Extensive Green Roofs: Require more upkeep with much deeper soil and a wider variety of plants.
