Gutter Guard for Colorbond® and Corrugated Metal Roofs Corroguard® is Leaf Stopper’s purpose-built gutter guard system for traditional curved corrugated metal roof profiles, includ ing many Colorbond® corrugated roofs commonly found across Australia. Leaves, twigs, bark and wind-blown debris can accumulate in exposed gutters, restricting outlets and creating another maintenance job around the home. Corroguard® helps reduce larger debris entering the gutter while allowing rainwater to pass through the aluminium Mesh Shield into the drainage system. For homeowners, that can mean fewer difficult gutter-cleaning jobs, less time spent working from ladders and greater confidence that the roofline is easier to inspect and maintain before storms, heavy leaf fall and bushfire season. See How Corroguard® Protects Corrugated Roofs Watch this overview to see how the Corroguard® system fits a corrugated metal roof and helps protect the gutter beneath it. Purpose-Built for Corrugated Roof Profiles Corrugated roofing has a distinctive curved profile. A gutter guard system needs components that follow those corrugations rather than relying on generic clips or a one-size-fits-all fixing method. Corroguard® uses purpose-designed Corrofast Saddles to secure Mesh Shield at the high points of compatible corrugations. At a traditional external gutter edge, Trimets secure the outer edge of the mesh. This creates a supported surface extending from the roof towards the gutter edge. The inclined installation helps keep larger debris above the gutter channel, where it can be removed more easily and may move from the surface under suitable dry and windy conditions. Wet leaves, branches and matted debris can still remain on top of any gutter guard and should be cleared when required. Part of the Leaf Stopper Roof Protection System Family Leaf Stopper is not a single universal gutter mesh. It is a family of profile-specific systems developed for different Australian roofs and gutter configurations. Corroguard®: Traditional curved corrugated metal roofs TILEGUARD™: Compatible concrete and terracotta tiled roofs DEK-762™: Compatible DEK-762-style metal roof profiles DEKGUARD™: Supported flat-based metal roof profiles COMGUARD™: Internal box gutters adjoining supported flat-based roof profiles Choosing the correct system matters because the roof-side components, fixing method and gutter configuration differ between profiles. How Leaf Stopper Mesh Shield Works Mesh Shield forms the protective surface across the gutter. It helps reduce leaves and larger debris entering the channel while allowing rainwater to pass through the mesh apertures. The correct Mesh Shield depends on the debris surrounding your property, the level of strength required and any applicable bushfire construction requirements. Watch the Mesh Shield Overview Choose the Right Mesh Shield Standard Mesh Aperture: 3.5mm × 3.5mm Aluminium thickness: 0.55mm Best suited to: General leaves, twigs and larger debris Material: Non-combustible aluminium Premium Mesh Aperture: 3.5mm × 3.5mm Aluminium thickness: 0.80mm Best suited to: Installations where a thicker, stronger mesh is preferred Material: Non-combustible aluminium Premium Mesh has the same aperture as Standard Mesh but uses aluminium that is approximately 46% thicker. It is not a finer-aperture mesh. Fine Mesh Aperture: 1.8mm × 1.8mm woven mesh Aluminium thickness: 0.40mm Best suited to: Pine needles, fine seeds and smaller leaf matter Material: Non-combustible aluminium Bushfire applications: The BAL-rated Mesh Shield option within the Leaf Stopper range Where Fine Mesh is intended to perform an ember-guard function, confirm the applicable material, aperture and installation requirements with your builder, building certifier or bushfire consultant. Product selection alone does not establish whole-building BAL compliance. What Comes in a Corroguard® Gutter Edge Kit? A Corroguard® gutter-edge kit includes the components required to protect a compatible traditional external gutter beside a corrugated roof. 250mm-wide aluminium Mesh Shield in your selected length and mesh type Trimets to secure the mesh at the compatible external gutter edge Corrofast Saddles to secure the mesh to the corrugated roof profile Colour-matched screws for a consistent finished appearance Always follow the current Corroguard® installation instructions for saddle positioning and component spacing. Do not rely on a universal “every second” or “every third” corrugation rule. What Comes in a Corroguard® Valley Kit? Corroguard® valley kits are available where separate protection is required for compatible corrugated roof valleys. 250mm-wide aluminium Mesh Shield in your selected length and mesh type Corrofast Saddles to secure the mesh to the corrugations Colour-matched screws Trimets are not required for the valley installation Valleys can involve complex water movement, roof junctions and flashing details. Follow the relevant installation instructions and engage a roofing professional where the valley is damaged, unusually configured or difficult to access safely. Protection That Supports Safer, Easier Home Ownership Cleaning exposed gutters can involve repetitive ladder use, awkward roof access and working around slippery surfaces. This can be especially challenging for older homeowners, people living alone and families who would prefer to spend less time worrying about roof maintenance. Corroguard® helps reduce the amount of larger debris entering the gutter, which may reduce how frequently extensive cleaning is required. That does not make the system maintenance-free, but it can make ongoing home care more manageable by: Keeping larger leaves and twigs above the gutter channel Making surface debris easier to identify Reducing concealed leaf accumulation inside the gutter Supporting easier inspection of the roofline Reducing the need to repeatedly remove temporary gutter inserts Providing greater peace of mind when storms or heavy leaf fall are forecast Suitable for a Range of Australian Properties Corroguard® may be suitable for compatible corrugated-roof properties affected by: Nearby trees and seasonal leaf fall Wind-blown bark, twigs and debris Regular storms and heavy rainfall Rainwater harvesting systems Bushfire-prone surroundings Recurring gutter-cleaning requirements Birds or other pests attempting to access the protected gutter edge A correctly installed system may help reduce access around the protected roof and gutter edge, but it cannot guarantee complete bird or vermin exclusion throughout the building. Supporting Rainwater Harvesting Corroguard® can provide an initial layer of debris reduction for homes collecting roof water in rainwater tanks. By helping reduce leaves, twigs and larger organic material entering the gutter, the system may reduce the load placed on downstream strainers and filters. It does not replace: First-flush diverters Tank inlet screens Appropriate filtration Tank maintenance Water-quality treatment required for the intended use No Gutter Guard Is Maintenance-Free Corroguard® is designed to reduce gutter maintenance—not eliminate it. Fine dust, pollen, silt and small particles may pass through the mesh and settle inside the gutter. Leaves and branches can also remain on the surface, particularly when wet or caught around roof features. Periodic inspection remains important to check: The surface of the Mesh Shield Downpipe entrances Gutter corners and ends Roof valleys Visible fixings and saddles Fine sediment inside the gutter Damage following storms or roof work The appropriate inspection frequency depends on surrounding vegetation, weather, roof design and local conditions. Plan Future Access with EasyAc® You may not need to access your gutter or downpipe for years. However, including a removable access point during the original installation means it is already available when an inspection or cleaning task eventually arises. The EasyAc® range provides screw-free local access through the Mesh Shield without requiring a long section of gutter guard to be removed. Steel EasyAc® The original EasyAc® model introduced in 2010 Manufactured from steel Uses a louvered lid that slides onto the base plate from one end EasyAc20® Released in 2025 Longer than the original Steel EasyAc® Manufactured from aluminium Available in a range of colours The lid is positioned beside the slotted tabs and pushed sideways into place Both models use patented internal tabs that are pushed underneath the Mesh Shield to hold the base plate in place. The lid does not rely on screws, so a screwdriver is not required each time it is removed or replaced. EasyAc® can provide useful local access near selected downpipe outlets, corners or other maintenance points. It does not automatically clear a blockage further down the downpipe or within underground stormwater infrastructure.

Frequently Asked Questions Will Corroguard® work on a Colorbond® roof? Corroguard® is designed for many traditional curved corrugated metal roof profiles, including compatible Colorbond® corrugated roofing. Confirm that your roof has the required curved corrugated profile before ordering. Is Corroguard® suitable for Trimdek or other flat-pan roofs? No. Trimdek and other supported flat-based metal profiles generally require DEKGUARD™, which uses Gripits secured to the roof pans. Confirm the roof manufacturer and exact profile before choosing a system. Can I install Corroguard® myself? Yes, capable DIY customers may install Corroguard® on a straightforward and safely accessible roof. Professional installation is recommended for high, steep, complex or difficult-to-access buildings. How much gutter guard do I need? Measure the total linear length of the external gutters and compatible valleys you want to protect. Measure each separate run and allow for the joins, corners and installation details shown in the current instructions. What kit lengths are available? Corroguard® kits are available in different lengths, including 5m, 10m, 15m and 30m options, depending on the selected product and configuration. Does Corroguard® completely stop gutter cleaning? No. Corroguard® helps reduce larger debris entering the gutter, but fine sediment and surface debris may still require periodic attention. Can I flush the gutter through Mesh Shield? Water may be directed through the Mesh Shield to help move loose fine sediment. For more direct local access, consider installing Steel EasyAc® or EasyAc20® during the gutter guard installation. Is Corroguard® suitable for properties with nearby trees? Yes. Corroguard® is commonly selected for properties affected by leaves, twigs, bark and other tree debris. Choose Standard, Premium or Fine Mesh according to the size and type of surrounding debris. Which mesh should I choose for pine needles? Fine Mesh is generally the most appropriate Leaf Stopper option for pine needles, fine seeds and smaller leaf matter because it has a 1.8mm × 1.8mm woven aperture. Is Corroguard® suitable for bushfire-prone properties? All Leaf Stopper Mesh Shield options are made from non-combustible aluminium. Fine Mesh is the BAL-rated mesh option within the range. Confirm the exact gutter-guard and ember-protection requirements for your property with the relevant building or bushfire professional. Does Corroguard® stop birds and pests? A correctly installed system may help reduce access around the protected gutter and roof edge. It cannot guarantee complete bird or vermin exclusion throughout the roof or building. Will Corroguard® prevent every gutter blockage or overflow? No gutter guard can guarantee this. Drainage performance also depends on gutter fall, gutter capacity, downpipe condition, stormwater infrastructure, rainfall intensity and ongoing maintenance. Can Corroguard® repair a damaged or poorly draining gutter? No. Existing corrosion, incorrect gutter fall, blocked downpipes, leaking joins and undersized drainage should be addressed before installing the gutter guard. Can I still inspect my gutters after installation? Yes. The gutter and Mesh Shield should remain part of your periodic roof inspection. Adding an EasyAc® access panel can provide removable local access without unscrewing a long section of mesh. Is EasyAc® included in the Corroguard® kit? No. Steel EasyAc® and EasyAc20® are optional access products sold separately. What comes with the Corroguard® gutter-edge kit? The gutter-edge kit includes 250mm Mesh Shield, Trimets, Corrofast Saddles and colour-matched screws in quantities appropriate to the selected kit. What comes with the Corroguard® valley kit? The valley kit includes 250mm Mesh Shield, Corrofast Saddles and colour-matched screws. Trimets are not used for the valley installation. Show more
