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

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

Half-Round Gutters: Known for their traditional appearance and efficient water flow.
4. Trough Drainage
This method integrates wide, shallow channels developed to intercept water before it accumulates.

Trench Drains: Ideal for large flat roofs, these systems frequently feature grates to keep particles out while directing water.

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

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

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