Complete Gutter Replacement Guide for Perth Homeowners (2026)
Gutters are one of those parts of your home that you rarely think about until they fail. When gutters corrode, sag, overflow, or pull away from the fascia, they can cause serious damage to your roof, walls, foundations, and landscaping. For Perth homeowners, replacing ageing gutters is one of the most practical investments you can make in protecting your property.
This guide covers everything you need to know about gutter replacement in Perth: the signs it is time, the materials and profiles available, what it costs, and how to choose the right system for your home.
Signs Your Gutters Need Replacing
Not every gutter problem requires full replacement — minor issues like a blocked downpipe or loose bracket can be repaired. But here are the signs that replacement is the better investment:
- Visible rust or corrosion. This is especially common along seams, joints, and the bottom of the gutter trough. Once rust has perforated the metal, patching is only a short-term fix.
- Multiple leaking joints. Older gutters with soldered or riveted joints often develop leaks at multiple points simultaneously. Modern seamless guttering eliminates this issue.
- Sagging sections. Gutters that sag between brackets have typically stretched under water weight and cannot be permanently straightened.
- Paint peeling on fascia boards. If the timber fascia behind your gutters shows moisture damage, water is likely overflowing or leaking behind the gutter.
- Foundation erosion or staining. Water overflowing from failed gutters can erode soil around your foundations and leave mineral stains on walls and paving.
- Age. Gutters over 20 to 25 years old in Perth’s climate have usually reached the end of their effective life, particularly if they are the original galvanised steel type common in homes built before the 1990s.
- Water stains on eaves. We often see brown rings or damp patches on the eave sheets, which usually indicates the old gutters lack proper overflow slots. This forces water backward into the roof cavity during heavy downpours.
Gutter Profiles Available in Perth
Perth homes use several standard gutter profiles. Understanding the differences helps you choose the right option for your roof and climate.
Quad Gutter (115mm)
The most common profile on Perth residential homes. Quad gutter has a rounded front face and is available in a wide range of Colorbond colours. It suits most standard residential roofs and handles Perth’s typical rainfall volumes effectively.
Best for: Standard single and double-storey residential homes.
Fascia Gutter (185mm)
A larger, flat-fronted profile that doubles as both gutter and fascia board. Fascia gutters create a clean, modern look and are popular on contemporary Perth homes. The larger capacity handles higher water volumes, making them suitable for homes with large roof catchment areas.
Best for: Modern architectural homes, properties with large roof areas, and areas that experience heavy concentrated rainfall.
Half-Round Gutter (125mm)
A traditional, semi-circular profile often used on heritage homes and Federation-style properties. Common in suburbs like Mount Lawley, Claremont, and Peppermint Grove where character homes predominate.
Best for: Heritage and character homes where period-appropriate detailing matters.
OG (Old Gothic) Gutter (125mm)
A classic profile with a decorative front lip that suits traditional home styles. OG guttering is still available but is less common on new installations. It is a good choice for maintaining the original look of older Perth homes.
Best for: Replacement on older homes where matching the existing profile is important.
Pro Tip: Regardless of the profile you choose, we strongly recommend specifying “slotted” gutters. These have small slots on the front face that allow water to overflow away from the house during extreme storms, preventing it from flooding your eaves.
Colorbond: The Standard for Perth Gutters
Colorbond steel by BlueScope is the dominant gutter material in Perth and across Western Australia. There is good reason for this — it is specifically engineered for Australian conditions.
Why Colorbond Suits Perth
- Corrosion resistance. Colorbond’s multi-layer coating system resists corrosion from salt air, making it ideal for coastal suburbs from Scarborough to Mandurah.
- UV stability. The paint finish is designed to resist fading and chalking under Australia’s intense UV, maintaining its appearance for decades.
- Heat reflectance. Lighter Colorbond colours reflect significant heat, keeping gutter temperatures lower and reducing thermal expansion stress.
- Colour range. Over 20 standard colours to match or complement any roof and exterior colour scheme.
Popular Colorbond Colours for Perth Gutters
| Colour | Best Suits |
|---|---|
| Surfmist | Light-coloured roofs, modern homes |
| Shale Grey | Mid-toned roofs, neutral exteriors |
| Woodland Grey | Darker roofs, bushland settings |
| Monument | Dark roofs, contemporary architecture |
| Classic Cream | Traditional homes, rendered exteriors |
| Paperbark | Warm-toned brick homes |
Alternatives to Colorbond
While Colorbond dominates the Perth market, other options include:
- Zincalume. The raw metal version without the coloured finish. Cheaper but prone to faster weathering in coastal areas.
- Aluminium. Lightweight and corrosion-resistant but more expensive. Occasionally used on high-end homes.
- PVC. Used in some budget applications but not suitable for Perth’s heat and UV levels.
Gutter Replacement Costs in Perth
Pricing depends on the profile, material, length, storey height, and complexity of the installation. Here are indicative costs for 2026:
| Item | Typical Cost |
|---|---|
| Quad gutter (Colorbond) | $45 - $65 per linear metre |
| Fascia gutter (Colorbond) | $55 - $85 per linear metre |
| Half-round gutter (Colorbond) | $50 - $75 per linear metre |
| Downpipes (90mm round) | $25 - $45 per linear metre |
| Old gutter removal and disposal | $10 - $20 per linear metre |
| Fascia board replacement (if needed) | $30 - $55 per linear metre |
For a typical three-bedroom Perth home with 30 to 40 metres of gutter line, expect a total replacement cost of approximately $1,800 to $3,500 including removal, new gutters, downpipes, and installation.
Factors That Influence Cost
- Storey height. Two-storey homes require scaffolding or elevated platforms, adding $400 to $1,000 to the total depending on site access.
- Fascia condition. If the timber fascia behind the old gutters has rotted, it will need replacing before new gutters can be fitted.
- Number of corners and joins. Complex rooflines with many corners cost more due to additional cutting, joining, and fabrication.
- Access difficulty. Homes with limited access, steep driveways, or adjacent structures that restrict scaffold placement may attract higher labour costs.
- Gutter guard installation. Adding gutter guards at the time of replacement adds $25 to $50 per linear metre but saves on future cleaning costs.
Choosing the Right Gutter System
Here are the key decisions to make with your roofer:
Profile
Match the profile to your home’s style and your roof’s water capacity needs. If you are unsure, Quad is the safe default for most Perth homes. If your roof has a large catchment area or you experience regular overflows, consider the larger Fascia profile.
Colour
Gutters can either match your roof colour for a seamless look or contrast with it for a more defined roofline. Your roofer can bring Colorbond colour samples to help you decide.
Downpipe Placement
Effective gutter performance depends on having the right number of downpipes in the right locations. Undersized or poorly placed downpipes are a common reason for gutter overflow. Your roofer should assess the roof area draining into each gutter run and recommend downpipe sizes and positions accordingly.
Gutter Guards
If your property has significant tree coverage — common in suburbs like Kalamunda, Mundaring, Darlington, and Roleystone in the Perth Hills — gutter guards fitted at the time of replacement can save years of maintenance and repeated cleaning costs.
The Replacement Process
A professional gutter replacement typically follows these steps:
- Inspection. The roofer assesses the existing gutters, fascia boards, downpipes, and brackets to determine the full scope of work.
- Quotation. A written quote detailing materials, colours, profiles, and all costs.
- Old gutter removal. Existing gutters, brackets, and downpipes are removed and disposed of.
- Fascia repair. Any damaged timber fascia is replaced to provide a solid mounting surface.
- New gutter installation. New gutters are cut to length on-site, fitted with correct fall (slope towards downpipes), and secured with new brackets.
- Downpipe connection. New downpipes are fitted, connected to existing stormwater drains or soakwells.
- Testing. The system is tested with water to ensure correct flow and no leaks.
- Clean-up. All waste materials are removed from the property.
Most standard gutter replacements on Perth homes are completed in a single day.
