Downpipes and gutters

Downpipes: The backbone of the drainage system 

Downpipes are the channels that direct water from your roof down to a safe discharge point. They are usually positioned at various points along the gutter line, ensuring that the water collected on the roof is quickly and efficiently drained away. A well-installed downpipe system helps prevent water from pooling on the roof, which can lead to leaks or even structural damage over time. 

When choosing downpipes, it’s important to consider their material and finish. Most modern systems offer downpipes made from robust, weather-resistant materials, which are designed to withstand the elements without rusting or deteriorating. The simplicity of a downpipe’s design means that it doesn’t have to be flashy. Instead, its strength lies in durability and proper installation. A poorly secured or undersized downpipe can result in slow drainage, increasing the risk of water damage during heavy rainfall. 

Gutters: Protecting the sides 

Along with downpipes, gutters form the next element of a roof drainage system. Gutters are fitted along the roofline and are designed to capture the rainwater as it runs off. They direct the water towards the downpipes, ensuring that water does not spill over and run down the side of the house. In this way, gutters help protect the roof’s edge, as well as the exterior walls of your home. 

Gutters often come in various profiles, and the material they’re made from plays a significant role in their performance. For example, some systems are constructed from acrylic-coated, hot-dip galvanised steel with a surface layer of high-built polyester (HBP). This material is lightweight, corrosion-resistant, and won’t fade from wind or sunlight. 

An effectively designed gutter will also include leaf guards or filters, especially in areas where trees can cause blockages. Ensuring that gutters remain clear is essential for the drainage system to work as intended, as even a slight clog can cause water to overflow and damage your facade.

FAQ

What is the purpose of gutters?

Gutters collect and direct rainwater away from your roof and foundation, preventing water damage to your home. They help avoid leaks, erosion, and flooding by safely channelling water to the ground or a drainage system. Properly functioning gutters protect your property from long-term damage.

How far apart should downpipes be?

Generally, downpipes should be spaced about 10 metres apart, depending on the roof size and rainfall intensity. However, always check local building regulations, as specific requirements may vary and influence the ideal placement.

How do you clean a blocked downpipe?

First, remove any leaves and debris from the gutter. Then, use a long rod or a pressure washer to clear the blockage in the downpipe. Test the system with water to ensure proper flow and repeat the necessary cleaning.
