Introduction
Installing aluminium gutters represents a reliable investment for property owners in the United Kingdom, providing robust protection against rainwater while enhancing aesthetic appeal. Aluminium systems offer superior longevity compared to alternatives, with a functional life expectancy exceeding 50 years. At Alugutter, we manufacture high-quality marine-grade aluminium gutters in-house, ensuring precision and durability. This guide outlines the installation process, drawing on our expertise to assist tradespeople and homeowners. For visual demonstrations, refer to our installation videos and downloadable installation guides.
Tools and Materials Required
Preparation ensures a smooth installation. Gather the following items:
- Measuring tape and spirit level
- Pencil or marker
- Metal cutting tools (mitre saw, circular saw, angle grinder, or hacksaw with appropriate metal-cutting blades)
- Drill with masonry or wood bits
- Screwdriver or power driver
- Sealant gun with low modulus silicone sealant, our code SU1
- Ladder or scaffolding for safe access
- Safety equipment (gloves, eye protection)
- Alugutter components: gutters, brackets, joints, outlets, downpipes, and fittings
Select blades designed for non-ferrous metals to avoid damage or burrs during cutting.
Site Preparation and Planning
Begin by assessing the roofline and planning the layout. Calculate the required fall for efficient drainage—aluminium gutters may be installed level or with a gentle slope of 1:600 towards outlets and downpipes. Measure the fascia board length and mark bracket positions. Brackets should be spaced at a maximum of one metre apart, reduced in high-wind or snowfall areas for added stability.
Clear debris from the fascia and ensure it is sound. For new installations, align with existing downpipes or plan new positions. Use our gutter and downpipe estimator for accurate material quantities.
Cutting Aluminium Gutters
Aluminium is lightweight and easy to work with, but precise cutting is essential. Mark measurements carefully and employ a mitre saw for angled cuts at corners, or a circular saw for straight sections. Angle grinders suit intricate adjustments, while hacksaws provide manual control for smaller tasks. Always use metal-specific blades to achieve clean edges without distortion.
For safety, secure the gutter in a vice or clamp. Post-cutting, deburr edges with a file to prevent injury and ensure smooth joints. View our video on how to cut aluminium panels for practical techniques applicable to gutters.
Installing Brackets and Gutters
Fix fascia brackets first, using stainless steel screws for secure attachment. Position the first bracket at the highest point, then string a line to maintain the desired fall. Snap or clip gutters into brackets, starting from one end.
For specific profiles:
- Half round and deepflow: Follow our Half Round & Deepflow Snapfit Gutters Install Guide and watch How To Install Aluminium Gutters (Half Round & Deepflow).
- Box gutters: Refer to the Box Snapfit Gutters Install Guide and How to Install Aluminium Gutters (Box Gutter).
- Moulded ogee: Use the Moulded Ogee Gutter Install Guide.
Apply our low modulus silicone sealant to joints for watertight seals, code SU1. Our Snapfit twinseal system simplifies this process, reducing installation time.
Fitting Outlets, Downpipes, and Hoppers
Position outlets above downpipe drains. Install downpipes vertically, using brackets spaced at 1.5 metres. For flush joint systems, consult the Flush Joint Downpipes Guide; for traditional, use the Traditional Downpipes Guide.
Connect to drainage systems, ensuring compliance with UK building regulations.
Superior Powder Coating for Longevity
Alugutter exceeds industry standards in polyester powder coating. Each item is hand-sanded for surface key, degreased, etch-primed, and then coated. This multi-step process prevents early paint failure, unlike simpler methods used by many coaters. Our architectural-grade powders ensure colour retention and resistance to UK weather.
Complementary Systems
Enhance your installation with our aluminium fascia and soffits or aluminium wall copings. For fascia and soffit fitting, watch How To Install Aluminium Soffit and Fascia and review the guide. For copings, see How To Install Aluminium Wall Coping and the guide.
Common Challenges and Solutions
- Thermal Expansion: Aluminium has minimal movement but allow a 3-5mm expansion gap at each abutting joint.
- Joint Leaks: Use ample sealant and test with water post-installation.
- High Winds: Reduce bracket spacing to 600mm.
