Kinds Of Roof Drainage Systems
Various methods can be utilized to make sure efficient roof drainage. The most common types consist of:
1. Gravity Drainage
This method makes use of gravity to direct water away from the roof surface.
Internal Drains: Located within the building's structure, these drains usage piping systems to get rid of water straight to the ground or the building's drainage system.
Roof Drainage Leaders: These are vertical pipes utilized to carry rainwater from the roof to the ground.
2. Slope Drainage
Creating slopes in the roof structure makes sure water flows towards designated drainage points.
Positive Drainage: A pitch or slope directs water to specific drains or scuppers.
Enhanced Slope Systems: These frequently feature structured designs to enhance water flow performance.
3. Gutter Systems
Gutters collect water that runs the roof edges, directing it securely away.
K-Style Gutters: Popularly used due to their aesthetic and functional advantages.
Half-Round Gutters: Known for their timeless appearance and efficient water flow.
4. Trough Drainage
This technique includes wide, shallow channels developed to obstruct water before it collects.
Trench Drains: Ideal for large flat roofings, these systems often feature grates to keep particles out while carrying water.
Capture Basins: Positioned strategically to gather rainwater and filter out particles.
5. Green Roofing Systems
These involve vegetation on rooftops that help in water absorption and management.
Extensive Green Roofs: Lower maintenance and require less soil depth.
Intensive Green Roofs: Require more upkeep with deeper soil and a larger variety of plants.
