Kinds Of Roof Drainage Systems
Different methods can be employed to make sure reliable roof drainage. The most common types consist of:
1. Gravity Drainage
This approach makes use of gravity to direct water away from the roof surface.
Internal Drains: Located within the building's structure, these drains pipes usage piping systems to eliminate water directly to the ground or the structure's drainage system.
Roof Drainage Leaders: These are vertical pipes used to carry rainwater from the roof to the ground.
2. Slope Drainage
Creating slopes in the roof structure ensures water streams towards designated drainage points.
Positive Drainage: A pitch or slope directs water to particular drains or ambushes.
Boosted Slope Systems: These typically include structured styles to enhance water flow effectiveness.
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 practical advantages.
Half-Round Gutters: Known for their traditional look and effective water flow.
4. Trough Drainage
This method incorporates wide, shallow channels designed to obstruct water before it builds up.
Trench Drains: Ideal for large flat roofing systems, these systems typically include grates to keep particles out while directing water.
Capture Basins: Positioned strategically to collect rainwater and filter out particles.
5. Green Roofing Systems
These include greenery on roofs that assist 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 variety of plants.
Secret Materials for Roof Drainage
