Aluminium Gutter

Why Choose Aluminium Guttering?

Aluminium has become one of the most trusted gutter materials for a reason. It combines strength, sustainability, and low maintenance with a neat, high-end look that suits a wide variety of buildings.

Key benefits include:

• Long Service Life: While aluminium gutters have a stated life expectancy of 30 years, many continue to perform for 60 years or more when maintained properly.
• Eco-Friendly: Each gutter is manufactured from 97% recyclable aluminium, helping to reduce environmental impact.
• Protective Coating: Our gutters are coated using ARP’s high-performance polyester powder coating for lasting durability and weather resistance.
• Low Maintenance: Unlike some traditional gutter materials, aluminium doesn't require regular repainting or intensive upkeep.
• Quick Installation: Our aluminium gutter systems are designed for efficient installation, using either a snap-fit jointing system or traditional nut and bolt fixings depending on the range. Both methods provide a secure fit while helping to reduce time and labour on site.

Sizes, Colours & Finishing Options

We supply aluminium gutter systems in a range of standard sizes, with matching aluminium downpipes available to ensure full system compatibility and effective water flow.

Our aluminium gutters are available in Black and Anthracite Grey as standard, but can also be supplied in any RAL colour on request. This allows you to match your rainwater system to the building’s exterior for a cohesive, professional finish. Bespoke colours are available across the full range, just let us know your requirements when placing your order.

Maintenance Made Simple

Maintaining aluminium guttering is easy, especially compared to more traditional materials. To preserve the appearance and performance:

• Clean the system regularly, removing leaves and other debris from the gutters and downpipes.
• Inspect fixings periodically to ensure everything remains securely in place.
• Rinse all visible surfaces annually with clean water to keep the powder coating looking fresh. In coastal or industrial areas, do this every six months instead.
• Act quickly on repairs if any damage is found to prevent more costly issues down the line.

We cover these steps and more in our full Aluminium Gutter Maintenance Guide.

For more information regarding using these products in coastal areas, read our guide to materials in coastal and high corrosion areas.

Installation Guidance

The installation process differs slightly between our extruded aluminium gutter and cast aluminium gutter ranges.

ARP’s Sentinel Extruded Aluminium Guttering features a simple but innovative snap-fit jointing system. Its components are simply clipped down into position before they are injected using ARP’s unique Arbosil 3923 sealant and left to cure. Not only does this create a strong long-lasting joint, but the process is also easy and mess-free. Installation must be completed using ARP’s Aluminium Gutter Sealant. For more information on this process, check out our jointing video demonstration. 

Cast Aluminium Gutters are designed to emulate the look of traditional cast iron gutters but feature an easy-to-follow installation process, simple enough even for first-time DIY-ers. Take a look at our comprehensive installation guide to find out more about how to fit this high-quality gutter system.

Lindab Aluminium Guttering

Lindab's pressed aluminium half round guttering is a complete metal rainwater system built to deliver a durable result without the weight or handling time of cast iron. The Swedish manufacturer's half round profile gives a clean, consistent roofline on refurbishments, new builds, extensions and light commercial work, and it's a straightforward upgrade from uPVC for anyone wanting metal guttering that lasts.

Why choose Lindab aluminium guttering?

Aluminium's low weight means lengths are easier to carry up ladders and scaffolding, fewer hands are needed on site, and jobs move faster than with cast iron. It won't rust, so corrosion isn't a concern, and its thermal movement is far lower than uPVC, so you get less of the joint creep, sagging and leaks that drive ongoing maintenance. The system includes rubber-sealed gutter joints, stop ends, angles and brackets designed to fit together precisely, so every install is repeatable. It’s backed by a 15-year manufacturer's warranty, and aluminium is fully recyclable.

Sizing gutters and downpipes

125mm is the standard choice for most domestic roofs; step up to 150mm for larger roof areas, steep pitches, valley discharge or exposed sites.

Downpipe choice depends on the water each outlet has to carry: 75mm suits small catchments such as porches and garages, 87mm covers most houses, and 100mm maximises discharge where fewer outlets are wanted. Outlet number and position matter as much as pipe diameter. When fitting, position the gutter brackets to give a fall of 10mm per 3m length towards the outlet. Unsure on sizing? Our expert team will be able to help, so do get in touch with any questions.

Frequently asked questions

Do all the downpipes fit both gutter sizes?

Yes. The 75mm, 87mm and 100mm round downpipes all connect to both the 125mm and 150mm half round gutters, so you can size outlets to the job without changing the gutter.

How does aluminium compare with uPVC guttering?

Aluminium is more rigid, moves far less with temperature changes and won't turn brittle under UV the way many plastics can. That makes it a longer-lasting upgrade when replacing tired plastic systems.

Is aluminium guttering easy to install?

Yes. The lightweight lengths and matched system fittings make handling and fitting quicker than heavier metal systems. As with any work at height, use suitable access equipment.
