Roof Drainage Leaders: These are vertical pipes used to bring rainwater from the roof to the ground.
2. Slope Drainage
Creating slopes in the roof structure makes sure water streams towards designated drainage points.

Positive Drainage: A pitch or slope directs water to specific drains pipes or scuppers.

Boosted Slope Systems: These typically include structured designs to enhance water flow performance.
3. Gutter Systems
Gutters collect water that runs off the roof edges, directing it safely away.

K-Style Gutters: Popularly used due to their visual and functional benefits.

Half-Round Gutters: Known for their timeless look and effective water flow.
4. Trough Drainage
This approach includes broad, shallow channels developed to obstruct water before it collects.

Trench Drains: Www.repairmywindowsanddoors.co.Uk Ideal for large flat roofing systems, these systems frequently feature grates to keep particles out while funneling water.

Capture Basins: Positioned tactically to collect rainwater and filter out particles.
5. Green Roofing Systems
These include plant life on rooftops that help in water absorption and management.

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

Intensive Green Roofs: Require more upkeep with deeper soil and a broader range of plants.
Key Materials for Roof Drainage
