Best Gutter Guard for DEK 762 Roof: The 2026 Australian Selection Guide

DEK-762™ is a purpose-built Leaf Stopper gutter guard system for compatible metal roof profiles matching the required DEK-762-style geometry.

The important word is compatible.

A roof should not be treated as a DEK-762™ application simply because it has raised ribs, looks similar to Trimdek®, or has a nominal cover width around 762mm.

Roof profiles can vary between manufacturers, generations and suppliers. Before ordering DEK-762™, compare your actual roof geometry with the current Leaf Stopper technical profile information.

This guide explains how to confirm compatibility, how DEK-762™ differs from DEKGUARD®, what comes in gutter-edge and valley kits, which Mesh Shield option to choose and what to check before placing an order.

What Is a DEK-762™ Roof?

DEK-762™ is Leaf Stopper's gutter guard system for compatible ribbed metal roof profiles with the required DEK-762-style geometry.

These roofs have raised ribs separated by flatter sections, but that visual description alone is not enough to establish compatibility.

Similar-looking metal profiles can differ in:

• Rib height
• Rib width
• Rib shape
• Pan geometry
• Sheet cover width
• Manufacturer tolerances

Those differences matter because the DEKAFast saddle must match the roof profile correctly.

How Do You Know Whether Your Roof Suits DEK-762™?

Start with the actual roof rather than the product name you think it resembles.

1. Identify the Manufacturer

Check building plans, invoices, roof documentation or visible product information where available.

2. Identify the Profile Name

Some compatible versions of profiles marketed under names such as Trimdek, Monoclad, Trimclad or Superdek may resemble DEK-762-style geometry.

That does not mean every roof sold under one of those names is automatically compatible.

3. Compare the Actual Geometry

Use the current DEK-762™ technical profile diagram and compare it with the roof.

Check:

• Rib shape
• Rib dimensions
• Pan arrangement
• Effective sheet-cover geometry

4. Take Clear Photos If You're Unsure

Useful photos include:

• The complete roof-sheet profile
• A view across several ribs
• The gutter edge
• Close-ups of the rib shape
• Any manufacturer markings

Do not order DEK-762™ solely because the roof “looks like Trimdek”.

DEK-762™ vs DEKGUARD®

These are separate Leaf Stopper systems.

DEK-762™

• Designed for compatible DEK-762-style geometry
• Uses profile-specific DEKAFast saddles
• Secures Mesh Shield at compatible roof ribs
• Uses Trimets at a compatible external gutter edge

DEKGUARD®

• Designed for supported flat-based metal roof profiles
• Uses patented Gripit brackets
• Gripits secure Mesh Shield to supported flat roof pans
• Uses Trimets at a compatible external gutter edge

DEK-762™ does not use Gripits, and DEKGUARD® does not use DEKAFast saddles.

What's Included in a DEK-762™ Gutter-Edge Kit?

Current DEK-762™ gutter-edge kits use:

• 250mm Mesh Shield
• Trimets
• DEKAFast saddles
• Colour-matched screws where available

What Do Trimets Do?

Trimets secure Mesh Shield to the compatible external gutter edge.

What Do DEKAFast Saddles Do?

DEKAFast saddles secure Mesh Shield to the compatible roof ribs.

They are profile-specific components rather than universal clips for every square-ribbed metal roof.

DEK-762™ Valley Gutter Guard

DEK-762™ can also protect compatible roof valleys.

The current valley configuration uses:

• 250mm Mesh Shield
• DEKAFast saddles
• Screws

Trimets are generally not required for the DEK-762™ valley configuration.

This is different from the gutter-edge kit.

Measure Valleys Separately

Do not combine roof-valley length with external gutter-edge length when calculating what to order.

Record them separately because the component requirements are different.

Choosing Standard, Premium or Fine Mesh Shield

Standard Mesh

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

Premium Mesh

• Aperture: 3.5mm × 3.5mm
• Thickness: 0.80mm aluminium
• Difference: Approximately 46% thicker than Leaf Stopper Standard Mesh

Premium Mesh is thicker than Standard Mesh.

It is not a finer mesh.

Fine Mesh

• Aperture: 1.8mm × 1.8mm woven mesh
• Thickness: 0.40mm aluminium
• Use: Finer debris such as pine needles and small seeds
• Bushfire: Leaf Stopper's BAL-rated Mesh Shield option where applicable

Which Mesh Is Best?

There is no single Mesh Shield grade that is automatically best for every DEK-762™ roof.

Consider:

• Surrounding vegetation
• Debris size
• Desired mesh thickness
• Applicable bushfire requirements
• Available colours

Do not choose Standard Mesh because of an unsupported claim that larger apertures guarantee greater stormwater intake.

Bushfire Considerations

Standard, Premium and Fine Mesh are all aluminium and non-combustible.

Only Fine Mesh is Leaf Stopper's BAL-rated Mesh Shield option where applicable.

Fine Mesh alone does not make a roof or building BAL compliant.

The correct specification depends on:

• The property's assessed BAL
• The building element being protected
• Whether the mesh is performing an ember-guard function
• The applicable construction requirements
• Installation details

If compliance matters, confirm the requirement with the relevant builder, certifier or bushfire consultant.

How Is DEK-762™ Installed?

The general gutter-edge process is:

1. Position the 250mm Mesh Shield.
2. Secure Mesh Shield to the compatible external gutter edge using Trimets and screws.
3. Make the required expansion or relief cuts so the Mesh Shield can follow the roof profile.
4. Secure Mesh Shield to compatible roof ribs using the supplied DEKAFast saddles and screws.

Do not invent universal:

• Saddle spacing
• Screw spacing
• Cut dimensions
• Overlap dimensions

Follow the current DEK-762™ installation instructions for those details.

Does DEK-762™ Need Silicone?

Silicone is not included as standard.

Current Leaf Stopper product information notes that silicone may be required when securing Mesh Shield around hip corners or at the tops of ridges.

What to Measure Before Ordering

Before ordering a DEK-762™ kit, record:

• □ Roof manufacturer
• □ Exact roof profile
• □ Compatibility with the current DEK-762™ technical diagram
• □ External gutter-edge length
• □ Valley length, measured separately
• □ Corners and roof transitions
• □ Downpipe locations
• □ Mesh Shield grade
• □ Colour preference
• □ Any bushfire requirements
• □ Potential EasyAc® access locations

For a wider measurement workflow, read How to Measure for Gutter Guards.

What About COLORBOND® Roofs?

COLORBOND® is branded steel rather than a roof profile.

A COLORBOND® roof might be:

• Traditional corrugated
• A supported flat-pan profile
• Compatible DEK-762-style geometry
• Another profile entirely

Therefore, DEK-762™ should never be sold as suitable for every COLORBOND® roof.

If you know only that your roof is COLORBOND®, identify the actual profile before ordering.

Maintenance After DEK-762™ Installation

DEK-762™ helps reduce leaves and larger debris entering the gutter, but it does not make the system maintenance-free.

Possible maintenance issues include:

• Fine sediment inside the gutter
• Wet leaves resting on Mesh Shield
• Branches lodged around roof features
• Storm debris
• Downpipe restrictions
• Moved or damaged components

There is no universal annual inspection interval.

Inspection frequency should reflect the surrounding vegetation, weather exposure, roof design and previous maintenance history.

For more detail, read Do You Still Have to Clean Gutters with Gutter Guards?.

Can EasyAc® Be Added?

EasyAc® is an optional local gutter-access product.

It can provide access through compatible Mesh Shield for inspection or local flushing.

EasyAc® is not automatically included in standard DEK-762™ kits.

There is also no universal requirement to fit one above every downpipe or at fixed intervals.

Can You Install DEK-762™ Yourself?

DIY installation may be suitable where:

• The roof profile has been correctly identified
• The DEK-762™ geometry has been confirmed
• The roof is straightforward
• The work area can be accessed safely
• The installer is competent and appropriately equipped

Professional installation is generally preferable for:

• High roofs
• Steep roofs
• Multi-storey properties
• Complex valleys
• Difficult roof transitions
• Commercial or industrial buildings
• Any project where safe access is uncertain

You can find a Leaf Stopper installer if professional fitting is more appropriate.

DEK-762™ Buying Checklist

Before placing an order, confirm:

• □ The roof geometry genuinely matches DEK-762™ requirements.
• □ You have not selected the system solely because the roof is called Trimdek, Monoclad or another similar profile.
• □ Gutter edges and valleys have been measured separately.
• □ The correct Mesh Shield grade has been selected.
• □ Required colours are available for the selected components.
• □ Any BAL requirements have been confirmed.
• □ EasyAc® locations have been considered.
• □ Safe DIY or professional installation has been decided.

Choose DEK-762™ by Geometry, Not by Name

The most important DEK-762™ buying rule is simple:

Confirm the actual roof geometry before ordering.

Similar-looking deck-style roofs are not necessarily interchangeable.

If your roof matches the DEK-762™ technical profile, the system provides purpose-designed roof saddles, Mesh Shield and gutter-edge components for that application.

If your roof instead has a supported flat-pan profile requiring Gripits, you may need DEKGUARD®.

Start with the DEK-762™ information page, compare DEK-762™ vs DEKGUARD®, or shop Leaf Stopper gutter guard systems once compatibility has been confirmed.

Frequently Asked Questions

What roof profiles does DEK-762™ fit?

DEK-762™ fits compatible metal roof profiles matching the required DEK-762-style geometry. Some versions of familiar profile families may be compatible, but profile name alone is not sufficient—compare the actual dimensions and shape before ordering.

Does DEK-762™ fit every Trimdek® roof?

No. Do not assume that. Supported Trimdek® profiles are commonly DEKGUARD® applications, while DEK-762™ requires specific compatible geometry.

Is DEK-762™ the same as DEKGUARD®?

No. DEK-762™ uses DEKAFast saddles on compatible roof ribs. DEKGUARD® uses Gripits on supported flat roof pans.

How wide is DEK-762™ Mesh Shield?

Current gutter-edge and valley kits use 250mm Mesh Shield.

Does the DEK-762™ valley kit use Trimets?

No. Current valley kits use 250mm Mesh Shield, DEKAFast saddles and screws without Trimets.

Can DEK-762™ protect roof valleys?

Yes, compatible DEK-762™ valley kits are available. Measure valley lengths separately from external gutter edges.

Which Mesh Shield should I use?

Choose according to debris type, desired mesh thickness and applicable bushfire requirements. Standard and Premium use the same 3.5mm × 3.5mm aperture, while Fine Mesh uses a 1.8mm × 1.8mm woven aperture.

Is Fine Mesh required on every bushfire-prone property?

No. Confirm the requirements applying to the assessed BAL and specific building application.

Can I install DEK-762™ myself?

Possibly, where the roof is correctly identified, straightforward and safely accessible. High, steep or complex roofs are generally better suited to professional installation.

Does DEK-762™ eliminate gutter cleaning?

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