2. Slope Drainage
Creating slopes in the roof structure ensures water flows towards designated drainage points.
Positive Drainage: A pitch or slope directs water to specific drains or scuppers.
Enhanced Slope Systems: These often include structured styles to improve water flow performance.
3. Gutter Systems
Gutters collect water that runs 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 timeless appearance and efficient water flow.
4. Trough Drainage
This approach includes broad, shallow channels developed to obstruct water before it collects.
Trench Drains: Ideal for large flat roofings, these systems frequently feature grates to keep debris out while funneling water.
Capture Basins: Positioned strategically to collect rainwater and residential Guttering filter out debris.
5. Green Roofing Systems
These include plants on rooftops that assist in water absorption and management.
Substantial 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.
