Complete Guide to Flat Pan Roof Gutter Guard Systems

DEK-762 vs DEKGUARD | Metal Roof Gutter Guard Guide

DEK-762™ and DEKGUARD® are both Leaf Stopper gutter guard systems for metal roofs, but they are not interchangeable.

The key difference is how Mesh Shield is secured to the roof.

DEK-762™ uses profile-specific DEKAFast saddles that secure Mesh Shield at compatible roof ribs. DEKGUARD® uses patented Gripit brackets secured to supported flat roof pans.

Choosing between them comes down to your actual roof manufacturer, profile and geometry—not simply whether the roof looks flat from the ground.

This guide explains the difference so you can identify the correct Leaf Stopper system before ordering.

Key Takeaways

  • DEK-762™ and DEKGUARD® are separate gutter guard systems with different roof-side fixing methods.
  • DEK-762™ uses DEKAFast saddles on compatible roof ribs.
  • DEKGUARD® uses patented Gripit brackets secured to supported flat roof pans.
  • Do not select DEK-762™ simply because a roof is described as Trimdek, Monoclad or another deck-style profile.
  • DEKGUARD® products should be selected using the roof manufacturer, exact profile and required Gripit configuration.
  • Standard, Premium and Fine Mesh Shield options are available for different debris, strength and bushfire requirements.

Understanding Flat-Based Metal Roof Profiles

Many Australian metal roofs use raised ribs separated by broad, relatively flat pans.

These profiles differ from traditional curved corrugated roofing, which has a continuous wave shape.

Examples of flat-pan or deck-style roof profiles can include products such as Trimdek®, Monoclad, Trimclad, Superdek and many other manufacturer-specific profiles.

However, similar-looking roofs can have different:

  • Rib shapes
  • Rib heights
  • Pan widths
  • Effective cover widths
  • Fixing requirements

That is why Leaf Stopper does not treat every flat-based metal roof as the same.

A gutter guard should be selected according to the actual roof profile and the fixing system designed for it.

DEK-762™ vs DEKGUARD®: The Main Difference

Feature DEK-762™ DEKGUARD®
Roof type Compatible DEK-762-style profiles Supported flat-based metal roof profiles
Roof fixing DEKAFast saddles Patented Gripit brackets
Fixing location Compatible roof ribs Supported flat roof pans
Selection method Confirm roof geometry against DEK-762 compatibility information Select according to roof manufacturer and exact profile
Standard gutter-edge Mesh Shield 250mm where specified Depends on the selected compatible DEKGUARD® configuration
External gutter edge Trimets on compatible gutter edges Trimets on compatible gutter edges

The important point is that DEK-762™ does not use Gripits and DEKGUARD® does not use DEKAFast saddles.

If you're unsure which fixing method applies to your roof, identify the profile before ordering rather than choosing the system based on appearance alone.

When Should You Use DEK-762™?

DEK-762™ is designed for compatible metal roof profiles matching the required DEK-762 geometry.

The standard gutter-edge system uses:

  • 250mm aluminium Mesh Shield
  • DEKAFast saddles
  • Trimets at a compatible external gutter edge
  • Colour-matched screws

DEKAFast saddles secure the Mesh Shield to compatible roof ribs.

This differs from DEKGUARD®, where Gripits are secured to supported flat pans.

Do Not Rely on the Profile Name Alone

Some roof-profile names can be used loosely or may differ between manufacturers and generations.

For this reason, a roof should not automatically be classified as DEK-762™ simply because it is described as a "762", "deck" or Trimdek-style profile.

Compare the actual roof geometry with the current DEK-762™ technical information before ordering.

When Should You Use DEKGUARD®?

DEKGUARD® is designed for supported flat-based metal roof profiles.

The system uses Leaf Stopper's patented Gripit brackets to secure Mesh Shield to supported flat roof pans.

The correct DEKGUARD® configuration depends on factors including:

  • Roof manufacturer
  • Exact roof-profile name
  • Profile geometry
  • Required Gripit quantity and positioning
  • External gutter configuration

Different roof profiles may therefore use different DEKGUARD® product configurations.

This is one reason profile identification matters before ordering.

Gripit Is a DEKGUARD® Component

Gripit should not be described as a generic Leaf Stopper metal-roof fastener.

CORROGUARD®, DEK-762™ and DEKGUARD® use different methods to secure Mesh Shield to the roof.

Using the correct profile-specific fixing method helps support the Mesh Shield and reduce unintended gaps or movement.

What Gutter Guard Should You Use on Trimdek®?

Trimdek® is a flat-pan metal roof profile, so do not automatically assume that a DEK-762™ kit is appropriate simply because some profile dimensions appear similar.

For supported Trimdek® applications, start with the DEKGUARD® range and confirm the exact manufacturer and roof profile.

Where a roof has specifically been confirmed against the DEK-762™ technical geometry, follow that product's compatibility information instead.

For a deeper explanation, read the Leaf Stopper Trimdek® gutter guard buying guide.

Why Profile-Specific Gutter Guard Matters

A generic roll of mesh cannot account for every metal roof shape.

The profile affects:

  • Where the mesh is supported
  • How it is mechanically secured
  • How the Mesh Shield transitions to the gutter
  • Which fixing components are required
  • How much material is required

Correct profile selection helps create a supported installation that follows the intended Leaf Stopper system design.

It does not guarantee that gutters will never block or overflow. Drainage performance still depends on the complete roof, gutter, downpipe and stormwater system.

Choose the Right Mesh Shield

Once you've identified the correct roof system, the next decision is the Mesh Shield.

Standard Mesh

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

Premium Mesh

  • Aperture: 3.5mm × 3.5mm
  • Thickness: 0.80mm aluminium
  • Difference: Approximately 46% thicker than Standard Mesh
  • Best suited to: Applications where a thicker, stronger mesh is preferred

Premium Mesh is thicker than Standard Mesh but uses the same aperture. It should not be described as a finer mesh.

Fine Mesh

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

Where Fine Mesh is being selected for a bushfire construction requirement, confirm the requirements applying to the specific property with the relevant builder, building certifier or bushfire consultant.

Fine Mesh alone does not establish whole-building BAL compliance.

Bushfire Considerations for Flat-Based Metal Roofs

Leaves, bark and other organic debris around gutters can contribute combustible material around the roofline.

Reducing larger debris entering the gutter can therefore form one part of broader bushfire preparation.

However, gutter guard should not be described as making a building fireproof or ember-proof.

Requirements vary according to:

  • The assessed Bushfire Attack Level
  • Building design
  • Applicable construction standards
  • Local requirements
  • Other construction details

Learn more on the Leaf Stopper Bushfire Protection page.

What Should You Measure Before Ordering?

For any metal roof, begin by measuring the total gutter length you intend to protect.

For DEKGUARD® applications, roof identification is equally important.

Record:

  • Total gutter length
  • Roof manufacturer, if known
  • Exact roof profile, if known
  • Clear photos showing the pans and ribs
  • Corner and return locations
  • Downpipe locations
  • Valley lengths where relevant
  • Preferred Mesh Shield type
  • Preferred colour
  • Whether EasyAc® access is required

Do not guess the roof profile based only on what it looks like from the ground.

For more guidance, see How to Measure for Gutter Guards.

What About Roof Valleys?

Valley protection should be considered separately from external gutter-edge protection.

Do not assume the components or Mesh Shield width used at the gutter edge are automatically the same for a valley.

Measure valley runs separately and check the current product and installation information for the selected Leaf Stopper system.

Damaged flashing, existing leaks or unusual roof junctions should be assessed before gutter guard is installed.

Can You Install DEK-762™ or DEKGUARD® Yourself?

DIY installation may be appropriate for capable users with a straightforward and safely accessible roof.

Typical preparation includes:

  • Cleaning existing debris from the gutter
  • Confirming the roof profile
  • Checking downpipe entrances
  • Inspecting the gutter for existing damage
  • Reading the current installation instructions
  • Using suitable tools and height-safety equipment

High, steep, fragile, complex or difficult-to-access roofs are generally better suited to professional installation.

You can find a Leaf Stopper installer if you would prefer someone else to complete the roof work.

Will Gutter Guard Affect My Roof Warranty?

Do not assume that installing any gutter guard automatically preserves—or voids—a roofing warranty.

Warranty conditions vary between roof manufacturers and products.

If the roof remains under warranty, check the manufacturer's current terms and requirements before mechanically fastening accessories to the roof.

Using a profile-specific Leaf Stopper system does not replace the need to comply with the roofing manufacturer's warranty conditions.

Maintenance Still Matters

Neither DEK-762™ nor DEKGUARD® should be treated as maintenance-free.

Mesh Shield helps reduce larger debris entering the gutter, but:

  • Fine sediment can pass through the mesh
  • Wet leaves can remain on the surface
  • Branches can lodge around roof features
  • Downpipe entrances still need inspection
  • Storms can deposit new debris

Inspection frequency should reflect your local vegetation, weather and property conditions.

Plan Access with EasyAc®

EasyAc® is an optional gutter access panel that provides local access through Mesh Shield.

It may make it easier to inspect selected gutter areas or flush loose fine sediment without removing a long section of mesh.

EasyAc® does not automatically clear deep downpipe or underground stormwater blockages.

Which System Should You Choose?

Use this simple rule:

  • Traditional curved corrugated roof? Start with CORROGUARD®.
  • Roof specifically confirmed as compatible DEK-762 geometry? Use DEK-762™.
  • Supported flat-based metal profile? Identify the manufacturer and profile and select the appropriate DEKGUARD® configuration.
  • Internal box gutter? Review COMGUARD® instead.

If you're unsure, do not guess.

Frequently Asked Questions

Is DEK-762™ the same as DEKGUARD®?

No. DEK-762™ uses DEKAFast saddles on compatible roof ribs. DEKGUARD® uses Gripit brackets secured to supported flat roof pans.

Does DEK-762™ suit every Trimdek® roof?

No. Do not select DEK-762™ based on the Trimdek® name alone. Confirm the actual roof profile and geometry before ordering. Supported Trimdek® applications will commonly be selected through the DEKGUARD® range.

What is Gripit used for?

Gripit is Leaf Stopper's patented fastening component used with compatible DEKGUARD® applications. It secures Mesh Shield to supported flat roof pans.

Does DEK-762™ use Gripits?

No. DEK-762™ uses profile-specific DEKAFast saddles.

Which gutter guard suits a traditional corrugated metal roof?

A traditional curved corrugated metal roof generally requires CORROGUARD®, not DEK-762™ or DEKGUARD®.

Which mesh should I choose for pine needles?

Fine Mesh is generally the most suitable Leaf Stopper option for pine needles and other fine debris because it uses a 1.8mm × 1.8mm woven aperture.

Is Fine Mesh suitable for bushfire applications?

Fine Mesh is the BAL-rated Mesh Shield option within the Leaf Stopper range where applicable. Confirm the requirements applying to your specific property rather than assuming product selection alone establishes compliance.

Will DEKGUARD® stop all leaves and debris?

No. DEKGUARD® helps reduce larger debris entering the gutter, but fine sediment can pass through the mesh and surface debris may still require periodic attention.

Can gutter guard prevent overflow on a flat-pan roof?

No gutter guard can guarantee against overflow. Drainage performance depends on rainfall, roof catchment, gutter capacity, gutter fall, downpipes, overflow provisions and downstream stormwater infrastructure.

Can I install DEKGUARD® myself?

DIY installation may be appropriate for capable users with a straightforward and safely accessible roof. Use a professional for high, steep, complex or difficult-access properties.
