Effective roof drainage with high-quality downpipes
Properly functioning downpipes are essential for directing rainwater safely away from your roof and protecting your property. Without a reliable drainage system, water can accumulate, leading to severe damage to façades, masonry, and foundations. By installing robust downpipes, you ensure that rainwater is channelled efficiently into the designated drainage or collection systems.
Whether you are constructing a new building or renovating an existing roof, these components offer a durable solution for both residential and commercial properties. They provide long-lasting protection against weather elements and structural deterioration.
Our extensive range of downpipes and accessories
In our assortment, you will find a comprehensive selection of downpipes and matching accessories from renowned manufacturers such as INEFA and zAmbelli. The range includes folded zinc pipes, pipe brackets, screw pins, and plinth elbows to complete your drainage system. For precise routing, we offer downpipe bends in various angles, including 40, 72, and 85 degrees, available with or without beads.
To match your exterior design, the components are available in multiple colours, including silver, anthracite, copper brown, white, grey, brown, and dark brown. You can select from various nominal sizes, such as DN 50, DN 75, DN 80, DN 100, and DN 125, as well as specific millimetre dimensions for rainwater flaps and collectors, ensuring a perfect fit for any roof size.
Choosing the right downpipe components and pricing
Selecting the correct downpipe depends primarily on the roof area and the expected volume of rainwater. Larger roofs require greater diameters, such as DN 100 or DN 125, to prevent overflowing during heavy downpours. Additionally, consider integrating rainwater flaps with or without sieves, or dedicated rainwater collectors, if you intend to harvest water for garden use.
When planning your project, you can expect prices for these drainage components to range from approximately 4.99 GBP to around 149.99 GBP (as of 2026). This allows for flexible budgeting, whether you need a single replacement bracket or a bulk pack of screw pins for a complete installation.
Frequently asked questions about downpipes
How do I determine the correct size for my downpipes?
The required size depends on the total surface area of your roof and the local rainfall intensity. Generally, a DN 80 pipe is sufficient for smaller roofs, while larger residential or commercial roofs require a DN 100 or larger diameter to ensure adequate drainage.
What is the purpose of a rainwater flap?
A rainwater flap allows you to divert water from the downpipe directly into a water butt or storage tank. Models equipped with a sieve also filter out leaves and debris, preventing blockages in your collection system.
How far apart should pipe brackets be installed?
To ensure stability and prevent the pipe from sagging or detaching during heavy rain or wind, pipe brackets should typically be installed at intervals of approximately two metres. Always secure the brackets firmly into the masonry using appropriate screw pins.
Can I connect different metals in my drainage system?
It is crucial to avoid combining incompatible metals, as this can lead to galvanic corrosion. Always ensure that your downpipes, brackets, and connectors are made from compatible materials, such as sticking entirely to zinc or appropriately coated components.
How often should the drainage system be cleaned?
You should inspect and clean your drainage components at least twice a year, ideally in spring and late autumn. Removing leaves, moss, and dirt prevents blockages and ensures that water flows freely away from the building.
Summary: Reliable protection through robust downpipes
Investing in high-quality downpipes and matching accessories ensures that your property remains safe from water-related structural issues. With the right combination of pipes, brackets, and collectors, you achieve a highly efficient and visually appealing drainage solution.
