Roof Drainage

Roof drainage is the process of directing water off the roof using slope design, gutters, and drainage systems. It prevents water pooling, leaks, and structural damage. Sloped roofs rely on gravity, while flat roofs require engineered drainage systems. In Vancouver, proper roof drainage is essential due to frequent rainfall, ensuring long-term roof durability and moisture control.
