Roof Drains Introduction

The primary purpose of any roof drainage system is to remove water from roofs as quickly as possible in a controlled and predictable way.

Factors including roof outlet size, shape, appearance and anticipated drainage requirements need to be taken into account. Design is usually the responsibility of consulting engineers familiar with the roof construction, piping systems and additional functions intended for particular roofs.


Building Regulations / Standards

International regulations and local building codes must be observed for all drainage installations. Local rainfall rates should be taken into account.

Roof Construction

Roof outlets are not multi-purpose and products are designed for use with specific types of roof construction (e.g. cold roof, warm roof, inverted roof parapet roof and balconies).

The depth of structural slab, thickness and location of insulation and the type and location of waterproof membrane are factors to consider at the outset of any drainage selection.
