Roof Drainage System

Accumulation of rainwater on a building’s rooftop can be hazardous for its structure if the water remains standing for longer duration. This is why, every building must have a roof drainage system to allow for the accumulated water to flow down the top of the building and pool in a reservoir or any other central collection point from which it can be reused or passed on further as per convenience and preference. There are several types of roof drainage systems being used at present in buildings around the world and these include the siphonic roof drainage system, gutters, scuppers and inner drains. Let us look at each of these in detail: 1.Gutters: These are the conventional system for roof drainage. Usually, they are found in pitched roofs and the rainwater glides into the gutter from the roof to be channeled into an underground reservoir or tank. The gutters work by action of gravity and are the most inexpensive option, which is why they are widely preferred. They also prevent the wat

A roof drainage system is instrumental in enabling the flow of accumulated water from the roof and preventing seepage, water logging, etc. Conventionally, roof drainage systems are designed in a manner that there is a slope which takes the water to the lowest level, where a downpipe is positioned. This downpipe carries off the water from the roof to the ground, to a tank or a sewage line. However, traditional roof drainage systems have a fundamental problem in that they carry air along with water which prevents the system from functioning at full efficiency and only carries limited amount of water in the pipes. It is here that siphonic roof drainage systems serve advantageous.

Water is a precious resource, and it is important to conserve it for not just meeting the requirements of the present population but also for the future generations. With rising awareness of the need for water conservation, there has also arisen an understanding for the need of rainwater management. Increasingly, people across the board are installing rainwater and stormwater management systems in industrial, commercial, agricultural as well as domestic setups to harness the water that more often than not goes to waste. There are manifold benefits to installing a stormwater or a rainwater management system, which are as follows:

One of the most important aspects to consider when planning a house or any other construction is planning for the roof drainage system, especially with flat roofs. If water accumulates on the rooftop, it can leak over time and cause seepage and weaken the structure of the construction. Whether you will need to install a siphonic roof drainage system or a traditional one will be determined by certain factors, which are as follows:
