Choosing the Best Leaf Guard for Colorbond Gutters: A 2026 Buyer’s Guide

Choosing gutter guard for a COLORBOND® roof starts with one important fact: COLORBOND® is the steel product, not the roof profile.

Two homes can both have COLORBOND® steel roofing while requiring completely different gutter guard systems.

One might have a traditional curved corrugated roof suited to CORROGUARD®. Another might use Trimdek®, Klip-Lok or another flat-based metal profile requiring DEKGUARD®. A third may have geometry compatible with the separate DEK-762™ system.

That means the best COLORBOND® gutter guard isn't determined by colour or material alone. You need to identify:

• Your actual roof profile
• Your gutter configuration
• The surrounding debris
• Your preferred Mesh Shield
• Any bushfire requirements
• Whether you're installing it yourself or using a professional

This guide walks through each decision so you can choose the correct Leaf Stopper system for your COLORBOND® roof rather than relying on a generic “fits COLORBOND” claim.

COLORBOND® Is Not a Roof Profile

This is the most important distinction in this entire guide.

COLORBOND® is BlueScope's pre-painted steel product used in a wide variety of Australian roofing and building applications.

It can be formed into many different roof profiles.

So saying:

“I have a COLORBOND® roof.”

does not give enough information to select gutter guard.

You might have:

• Traditional curved corrugated roofing
• Trimdek®
• Klip-Lok
• Spandek
• Monoclad
• Trimclad
• Another flat-based profile
• A profile with DEK-762-compatible geometry

Each roof shape creates different roof-side fixing requirements.

That is why Leaf Stopper provides several separate product families rather than one universal “COLORBOND gutter guard”.

Step 1: Identify Your COLORBOND® Roof Profile

Before measuring Mesh Shield or selecting a colour, identify the roof profile as accurately as possible.

Look for:

• Manufacturer
• Profile name
• Rib shape
• Rib height
• Flat-pan geometry
• Sheet cover width
• Visible or concealed roof fasteners

Do not guess based solely on appearance from the ground.

Why Manufacturer Matters

Different manufacturers can offer roof sheets that look broadly similar while using different dimensions.

This becomes particularly important with DEKGUARD®, because the appropriate Gripit configuration depends on the supported manufacturer and profile.

If you aren't sure what you have, take clear photographs of:

• The roof profile
• The gutter edge
• A section looking across the ribs
• Any available manufacturer markings or paperwork

Our How to Measure for Gutter Guards guide explains what information to collect before ordering.

Corrugated COLORBOND® Roofs: CORROGUARD®

If your COLORBOND® roof uses a compatible traditional curved corrugated metal profile, start with CORROGUARD®.

CORROGUARD® is purpose-built for traditional curved corrugated metal roofing, including many COLORBOND® corrugated roofs.

A current external gutter-edge CORROGUARD® kit uses:

• 250mm aluminium Mesh Shield
• Trimets at the compatible gutter edge
• Corrofast Saddles on the corrugated roof profile
• Colour-matched screws

The shaped Corrofast Saddles are specific to the curved corrugated roof geometry.

Does CORROGUARD® Suit Every COLORBOND® Roof?

No.

This is an important distinction.

CORROGUARD® is for compatible traditional curved corrugated profiles.

It should not be sold as a universal COLORBOND® gutter guard.

If your COLORBOND® roof has broad flat pans and raised ribs, you will generally need to look at DEKGUARD® or, where the geometry specifically matches, DEK-762™ instead.

You can view the CORROGUARD® product range for current options.

Trimdek®, Klip-Lok and Other Flat-Based COLORBOND® Roofs

Many modern metal roof profiles have broad flat pans separated by raised ribs.

These roofs need a very different fixing method from traditional corrugated roofing.

Leaf Stopper's main system for supported flat-based metal roof profiles is DEKGUARD®.

How DEKGUARD® Is Different

DEKGUARD® uses patented Gripit brackets.

Gripits secure Mesh Shield to compatible supported flat roof pans.

The standard external gutter-side configuration then uses Trimets and screws at the gutter edge.

DEKGUARD® does not use generic corrugated saddles over the roof ribs.

What About Trimdek®?

Trimdek® is one of the most frequently searched flat-pan roof profiles in Australia.

For supported Trimdek® applications, DEKGUARD® is generally the Leaf Stopper system to investigate first.

However, exact manufacturer and profile identification still matters.

Read the Trimdek Gutter Guard Buying Guide for a dedicated explanation.

What About Klip-Lok?

DEKGUARD® is available for selected supported Klip-Lok profiles.

Do not order simply by selecting “Klip-Lok” generically. Confirm the actual variant before choosing the Gripit configuration.

When Does DEK-762™ Apply?

DEK-762™ is a separate Leaf Stopper system for compatible DEK-762-style roof geometry.

Unlike DEKGUARD®, DEK-762™ uses:

• Mesh Shield
• Trimets
• DEKAFast saddles
• Screws

Those saddles secure Mesh Shield at compatible roof ribs.

Do Not Choose DEK-762™ Just Because the Roof Looks Like Trimdek®

A profile name or approximate cover width does not automatically establish DEK-762™ compatibility.

Confirm the actual geometry first.

What About COLORBOND® Internal Box Gutters?

Some commercial, architectural and residential metal roofs use internal box gutters rather than conventional external fascia gutters.

A compatible internal box gutter requires a different system again.

COMGUARD™ spans between a wall or vertical upstand and a supported adjoining flat-based roof profile.

It uses:

• Clampers on the wall or vertical side
• Gripits on the supported adjoining flat roof pans
• Appropriately selected Mesh Shield

Do not use a conventional CORROGUARD® or DEKGUARD® external gutter configuration as a substitute for an internal box-gutter design.

Choosing Mesh Shield for a COLORBOND® Roof

Once the roof-specific system has been identified, choose the Mesh Shield.

Standard Mesh

• Aperture: 3.5mm × 3.5mm
• Thickness: 0.55mm aluminium
• Material: Non-combustible
• Typical use: General leaves, twigs and larger debris

Premium Mesh

• Aperture: 3.5mm × 3.5mm
• Thickness: 0.80mm aluminium
• Difference: Approximately 46% thicker than Standard
• Material: Non-combustible

Premium Mesh is thicker than Standard Mesh.

It does not have a finer aperture.

Fine Mesh

• Aperture: 1.8mm × 1.8mm woven mesh
• Thickness: 0.40mm aluminium
• Typical use: Pine needles, fine seeds and smaller debris
• Bushfire applications: Leaf Stopper's BAL-rated Mesh Shield option where applicable

Does Standard Mesh Let More Rainwater Into the Gutter?

Do not choose Standard Mesh based on a blanket claim that its larger aperture guarantees greater water capture in heavy rain.

Rainwater performance depends on:

• Rainfall intensity
• Roof pitch
• Roof catchment
• Mesh condition
• Surface debris
• Gutter dimensions
• Gutter fall
• Downpipe capacity
• Overflow provisions

Select Mesh Shield primarily according to debris, strength preference and applicable bushfire requirements.

Choosing a Colour for Your COLORBOND® Gutter Guard

Colour is one of the obvious advantages of a powder-coated aluminium gutter guard system.

Leaf Stopper Mesh Shield and associated components are available in a range of colours designed to complement popular Australian roof and gutter finishes.

You might choose to coordinate the gutter guard with:

• The roof
• The gutter
• The fascia
• Another dominant exterior colour

Should Mesh Match the Roof or Gutter?

There is no technical requirement that it must match one or the other.

For visual integration, consider which surface the Mesh Shield will sit against and which colour will be least visually prominent from normal viewing positions.

If colour matching matters to you, compare physical samples where possible rather than relying entirely on screen colours.

For more information about finish selection, read The Homeowner's Guide to Powder Coated Gutter Guards.

Is Every Leaf Stopper Component Available in Every COLORBOND® Colour?

Do not assume so.

Colour availability varies between Mesh Shield grades, components and product configurations.

Check the current product selection when ordering.

Will Aluminium Gutter Guard Cause Galvanic Corrosion on COLORBOND® Steel?

This deserves a more careful answer than simply saying “aluminium and COLORBOND® are compatible”.

Material compatibility on coated-steel roofing depends on the complete installation, including:

• The materials in contact
• Surface coatings
• Fasteners
• Environmental exposure
• Water paths
• Installation details

Leaf Stopper uses powder-coated aluminium Mesh Shield and purpose-designed components for its systems, but that should not be turned into a universal claim that any aluminium accessory can be installed anywhere on COLORBOND® steel without compatibility considerations.

BlueScope publishes technical guidance covering good installation practice and compatible fastener selection for COLORBOND® and other coated-steel building products.

If maintaining a current roofing warranty is important, review the applicable manufacturer requirements before mechanically fastening additional components to the roof.

View BlueScope's current technical library for COLORBOND® steel installation and accessory guidance.

Will Gutter Guard Void My COLORBOND® Roof Warranty?

Do not assume either answer.

It is not accurate to say:

“Installing aluminium gutter guard won't void your COLORBOND® warranty.”

Warranty conditions can depend on the actual roof product and how accessories are installed.

Before modifying a warranted roof, check:

• Current roof manufacturer requirements
• Fastener compatibility
• Penetration requirements
• Accessory-material requirements
• Installation practices
• Maintenance obligations

If you're uncertain, seek confirmation before installation rather than assuming the gutter guard has no warranty implications.

Choosing Gutter Guard for a COLORBOND® Roof in a Bushfire-Prone Area

All three Leaf Stopper Mesh Shield grades are aluminium and non-combustible.

That does not mean all three have the same BAL status.

• Standard: non-combustible, not Leaf Stopper's BAL-rated option.
• Premium: non-combustible, not Leaf Stopper's BAL-rated option.
• Fine: Leaf Stopper's BAL-rated Mesh Shield option where applicable.

Fine Mesh uses a 1.8mm × 1.8mm woven aperture.

Do not interpret that as meaning every COLORBOND® roof in a bushfire-prone area legally requires Fine Mesh.

Requirements depend on factors including:

• The assessed BAL
• The building element being protected
• Whether the mesh is functioning as a leaf guard, ember guard or both
• Applicable construction requirements
• Jurisdiction

Likewise, Fine Mesh does not make an entire building BAL compliant.

For detailed information, visit the Leaf Stopper Bushfire Protection page.

If your property is BAL 29, the BAL 29 Gutter Guard Buying Guide provides more specific information.

Can COLORBOND® Gutter Guard Help with Birds and Pests?

A securely fitted gutter guard may help reduce bird and pest access around the parts of the gutter and roof edge that it physically protects.

It should not be described as:

• Bird-proof
• Rat-proof
• Possum-proof
• Vermin-proof

Animals may access other areas around:

• Eaves
• Flashing
• Roof penetrations
• Vents
• Damaged building elements

For pest-related applications, correct roof-profile fit and secure fixing are generally more important than selecting Fine Mesh purely because it has smaller apertures.

Does Gutter Guard Make COLORBOND® Gutters Maintenance-Free?

No.

Leaf Stopper helps reduce leaves, twigs and larger debris entering the gutter, but:

• Dust may pass through Mesh Shield
• Fine sediment can accumulate
• Wet leaves may remain on the mesh surface
• Branches can lodge around roof features
• Downpipe entrances may still need inspection

There is no universal rule that gutters only need cleaning every few years or that they must be inspected exactly once every year.

Inspection frequency depends on the property and surrounding conditions.

Read Do You Still Have to Clean Gutters with Gutter Guards? for a detailed explanation.

What About EasyAc®?

EasyAc® is an optional local inspection-access product.

It can provide access through compatible Mesh Shield so you can inspect a selected gutter location without removing a long section of mesh.

EasyAc® may be useful near:

• Selected downpipes
• Long gutter runs
• Corners
• Other planned inspection areas

There is no universal rule that EasyAc® must be fitted above every downpipe or at fixed intervals.

What to Measure Before Ordering Gutter Guard for a COLORBOND® Roof

Before ordering, record:

• □ Roof manufacturer
• □ Exact roof profile
• □ Total length of each gutter run
• □ External and internal corners
• □ Valleys
• □ Downpipe locations
• □ Gutter configuration
• □ Standard, Premium or Fine Mesh preference
• □ Colour preference
• □ Any bushfire requirements
• □ Potential EasyAc® access locations

If the roof profile is uncertain, resolve that before choosing the system.

This table is a starting point, not a substitute for profile confirmation.

The exact manufacturer, profile and gutter configuration should still be checked before ordering.

So, What Is the Best Gutter Guard for a COLORBOND® Roof?

The best COLORBOND® gutter guard is the one designed for the actual roof profile beneath the COLORBOND® finish.

Do not choose based only on:

• The word COLORBOND®
• Colour
• Mesh material
• A generic “metal roof” description

Instead:

1. Identify the roof manufacturer and profile.
2. Identify the gutter configuration.
3. Select CORROGUARD®, DEKGUARD®, DEK-762™ or COMGUARD™ as appropriate.
4. Select Standard, Premium or Fine Mesh Shield.
5. Select the required length and available colour.
6. Consider future maintenance access.
7. Confirm any warranty or bushfire requirements that apply.
8. Choose DIY or professional installation according to access and complexity.

Frequently Asked Questions

What is the best gutter guard for a COLORBOND® roof?

It depends on the roof profile. Traditional curved corrugated COLORBOND® roofs may suit CORROGUARD®, while supported flat-based profiles may require DEKGUARD®. Compatible DEK-762-style profiles use the separate DEK-762™ system.

Does CORROGUARD® fit every COLORBOND® roof?

No. CORROGUARD® is designed for compatible traditional curved corrugated metal roof profiles, including many COLORBOND® corrugated roofs.

What gutter guard suits a COLORBOND® Trimdek® roof?

Supported Trimdek® applications generally start with DEKGUARD®, but you should confirm the exact manufacturer and profile before ordering the required Gripit configuration.

Can DEK-762™ be used on Trimdek®?

Only where the actual roof geometry has been confirmed as compatible with DEK-762™. Do not select it solely from the Trimdek® name or an assumed sheet cover width.

Will aluminium gutter mesh rust?

Aluminium does not rust in the same way as ferrous steel, but it can still be affected by environmental conditions and corrosion mechanisms. Leaf Stopper uses powder-coated aluminium Mesh Shield designed for exposed gutter-guard applications.

Can aluminium gutter guard cause galvanic corrosion on COLORBOND® steel?

Material compatibility depends on the complete combination of materials, coatings, fasteners, moisture and installation details. Do not rely on a blanket statement that any aluminium accessory is automatically compatible with every COLORBOND® application.

Will Leaf Stopper void my COLORBOND® warranty?

Do not assume either way. Check the current requirements applying to the specific roof product and accessory installation, particularly where the roof remains under manufacturer warranty.

Can I match gutter guard to my COLORBOND® roof colour?

Leaf Stopper Mesh Shield and components are available in a range of colours intended to complement popular Australian roofing and gutter finishes. Exact availability depends on the Mesh Shield and product selected.

Do I need Fine Mesh on a COLORBOND® roof?

Not simply because the roof is COLORBOND®. Choose Fine Mesh where finer debris or an applicable BAL-rated requirement makes it appropriate.

Is Fine Mesh required on every COLORBOND® roof in a bushfire-prone area?

No. The correct specification depends on the property's assessed BAL, the building element and applicable construction requirements.

Does COLORBOND® gutter guard stop birds?

A correctly installed system may help reduce access around the protected gutter and roof edge, but it cannot guarantee complete bird or pest exclusion throughout the property.

Do gutter guards eliminate cleaning?

No. They help reduce larger debris entering the gutter, but periodic inspection and maintenance remain important.
