Kinds Of Roof Drainage Systems
Numerous approaches can be used to make sure effective roof drainage. The most common types consist of:
1. Gravity Drainage
This technique uses gravity to direct water far from the roof surface area.

Internal Drains: Located within the building's structure, these drains use piping systems to eliminate water straight to the ground or the structure's drainage system.

Roof Drainage Leaders: These are vertical pipes utilized to carry rainwater from the roof to the ground.
2. Slope Drainage
Producing slopes in the roof structure ensures water flows towards designated drainage points.

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

Improved Slope Systems: These often include structured designs to improve water circulation 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 benefits.

Half-Round Gutters: Known for their traditional appearance and effective water circulation.
4. Trough Drainage
This method incorporates large, shallow channels designed to obstruct water before it accumulates.

Trench Drains: Ideal for big flat roofs, these systems often feature grates to keep particles out while carrying water.

Catch 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 wider range of plants.
