What is a Roof Drainage System?
A roof drainage system is designed to channel water off the roof and away from the building’s structure. It consists of various components, including gutters, downspouts, and drains, which work together to manage rainwater effectively. Proper drainage helps to prevent water pooling, which can lead to leaks, mold growth, and structural damage.

Types of Roof Drainage Systems
There are several types of roof drainage systems, each suited for different building types and climates:

Gutter Systems
Gutters are typically installed along the eaves of a roof and collect rainwater, directing it toward downspouts. This system is common in residential buildings and is effective for sloped roofs.

Internal Drains
Internal drains are embedded within the roof structure and are ideal for flat roofs. They collect water and funnel it through pipes that lead down into the building’s drainage system. This type minimizes the visibility of drainage components.

Scupper Drains
Scuppers are openings in the parapet walls of a flat roof. They allow water to flow directly off the roof into a drainage system below. Scupper drains are often used in combination with internal drains for added efficiency.

Overflow Drains
Overflow drains are secondary drainage systems designed to handle excess water in case the primary system fails. These are essential for preventing catastrophic water damage during heavy rainfall.
