3. Gutter Systems

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

• K-Style Gutters: Popularly used due to their visual and functional advantages.

• Half-Round Gutters: Known for their timeless look and efficient water flow.

4. Trough Drainage

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

• Trench Drains: Ideal for big flat roofings, these systems typically feature grates to keep particles out while funneling water.

• Capture Basins: Positioned tactically to collect rainwater and filter out debris.

5. Green Roofing Systems

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

• Extensive Green Roofs: Lower maintenance and need less soil depth.

• Intensive Green Roofs: Require more upkeep with much deeper soil and a larger variety of plants.

Secret Materials for Roof Drainage

The products used for roof drainage systems significantly affect their sturdiness and efficiency.

Best Practices for Roof Drainage
