2. Slope Drainage
Producing slopes in the roof structure guarantees water streams towards designated drainage points.
Positive Drainage: A pitch or slope directs water to specific drains pipes or scuppers.
Enhanced Slope Systems: These frequently feature structured styles to enhance water circulation efficiency.
3. Gutter Systems
Gutters collect water that runs off the roof edges, directing it securely away.
K-Style Gutters: Popularly utilized due to their aesthetic and practical benefits.
Half-Round Gutters: Known for their traditional appearance and efficient water flow.

Extensive Green Roofs: Lower maintenance and require less soil depth.
Intensive Green Roofs: Require more upkeep with deeper soil and a wider range of plants.
Secret Materials for Roof Drainage
The materials used for roof drainage systems significantly affect their toughness and efficiency.
| Material Type | Benefits | Downsides |
|---|---|---|
| PVC | Lightweight, corrosion-resistant | Susceptible to UV damage |
| Cast Iron | Resilient, sound-dampening | Much heavier, prone to rust |
| Aluminum | Lightweight, resistant to deterioration | Can be dented quickly |
| Stainless Steel | Very resilient, corrosion-resistant | Expensive |
| Concrete | Long-lasting, robust | Heavy, can crack without maintenance |
