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

K-Style Gutters: Popularly utilized due to their visual and practical benefits.

Half-Round Gutters: Known for their timeless appearance and effective water circulation.
4. Trough Drainage
This approach includes wide, shallow channels developed to intercept water before it accumulates.

Trench Drains: Ideal for big flat roofing systems, these systems frequently feature grates to keep particles out while transporting water.

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

Comprehensive 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.
