Kinds Of Roof Drainage Systems

Different techniques can be employed to ensure efficient roof drainage. The most common types consist of:

1. Gravity Drainage

This technique uses gravity to direct water away from the roof surface area.

• Internal Drains: Located within the structure's structure, these drains usage piping systems to remove water directly to the ground or the structure's drainage system.

• Roof Drainage Leaders: These are vertical pipes used to bring rainwater from the roof to the ground.

2. Slope Drainage

Producing slopes in the roof structure ensures water streams towards designated drainage points.

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

• Boosted Slope Systems: These frequently feature structured styles to enhance water flow effectiveness.

Gutters collect water that runs off the roof edges, directing it securely away.

• K-Style Gutters: Popularly utilized due to their aesthetic and functional benefits.

• Half-Round Gutters: Known for their classic look and effective water circulation.

4. Trough Drainage

This technique integrates broad, shallow channels created to obstruct water before it accumulates.

• Trench Drains: Ideal for big flat roofing systems, these systems often feature grates to keep debris out while channeling water.

• Catch Basins: Positioned tactically to gather rainwater and filter out debris.

5. Green Roofing Systems

These include plants on rooftops that assist in water absorption and management.

• Comprehensive Green Roofs: Lower maintenance and require less soil depth.

• Extensive Green Roofs: Require more maintenance with much deeper soil and a broader range of plants.

Key Materials for Roof Drainage

The materials used for roof drainage systems considerably impact their resilience and efficiency.

Best Practices for Roof Drainage
