Discover how to choose and install the right Leaf Stopper DEK762 kit for your Lysaght Trimdek or Dek 762 roof profile to help reduce maintenance and protect your home.
A Dek 762 or Trimdek roof gives your property a clean, modern look, but its unique profile of deep ribs and wide, flat pans presents a challenge for standard gutter guards. Generic solutions simply don't fit, leaving gaps that allow leaves and pests to enter your gutters. The key to effective protection is a system designed specifically for this profile.
This guide walks you through everything you need to know about choosing and fitting the Leaf Stopper DEK762 gutter guard system. We’ll cover how its purpose-built components provide a secure, professional finish and give you the confidence to tackle the installation yourself.
Understanding Dek 762 and the Leaf Stopper DEK762 System
The Dek 762 roof profile, often known by the Lysaght brand name Trimdek, is defined by its trapezoidal ribs and broad, flat pans that provide 762mm of cover. This design is excellent for shedding water but makes fitting gutter guards tricky.
- What makes Dek 762 unique: Unlike corrugated roofing, Dek 762 has deep, angular ribs and wide, flat sections. This means standard curved saddles designed for corrugated iron won't sit flush, creating an insecure fit.
- Why standard saddles are unsuitable: Attempting to use generic or corrugated saddles on a Dek 762 roof can result in poor contact, mesh sagging, and gaps that reduce the effectiveness of the gutter guard.
- The role of the DEK762 system: Our system is engineered exclusively for this profile. It uses purpose-manufactured DEKAFast saddles that fit over the ribs, helping ensure the mesh is held securely against the roof surface.
- Overview of components: Each kit includes our high-quality Aluminium Mesh Shield, Trimets for the gutter edge, and the custom-designed DEKAFast saddles and screws needed for installation.
Why Profile Matching Matters
Achieving a long-lasting and effective result depends on using components that match your roof's specific dimensions. The DEK762 system is engineered for the rib height and pan width of Trimdek-style sheeting.
Using the wrong fasteners can lead to mesh lifting in high winds, sagging between ribs, or creating entry points for pests and debris. A profile-specific system helps create a cleaner, more secure fit that performs reliably in demanding Australian conditions.
The Leaf Stopper Advantage
When you choose Leaf Stopper, you're investing in a system designed for Australian roofs and local conditions.
- Australian owned and invented: Leaf Stopper understands Australian roofs and the challenges they face, from heavy rain to harsh sun.
- Tested materials and proven design: Our materials and systems are designed for long-term performance in Australian conditions.
- Focus on durability: We use powder-coated aluminium for key components, helping reduce corrosion risk and UV-related degradation compared with plastic alternatives.
Choosing the Right DEK762 Kit: Mesh Options & Coverage
The Leaf Stopper DEK762 system is designed for a specific fit, so choosing your kit is straightforward. You don't need to calculate Gripits or select a DEKGUARD product. For this roof profile, you need the dedicated DEK762 kit.
Your main decisions are selecting the right mesh type and ordering enough material to cover your gutters.
-
Step 1: Choose Your Mesh Type. Leaf Stopper offers three aluminium mesh options to suit different environments:
- Standard Mesh: Ideal for general leaf protection from large and medium debris.
- Premium Mesh: Features the same 3.5mm x 3.5mm aperture as Standard Mesh but is manufactured from thicker aluminium. At 0.80mm thick, Premium Mesh is approximately 46% thicker than Standard Mesh, providing increased strength and durability.
- Fine Mesh: Our finest option, designed for excluding very small debris and helping reduce ember entry in fire-prone areas. It is the only mesh in the Leaf Stopper range that is BAL-rated.
- Step 2: Select Your Mesh Width. Our kits are available in two standard widths. For most standard residential gutters, the 250mm mesh is suitable. For wider box gutters or unique applications, the 500mm width provides extra coverage.
- Step 3: Calculate Your Required Length. Measure the total length of the gutter edges you need to protect. DEK762 kits are available in various lengths, allowing you to order what you need for your project.
What's Included in a DEK762 Kit?
Every Leaf Stopper DEK762 kit comes with the components required for installation. You’ll receive:
- Your chosen length and width of Aluminium Mesh Shield
- Colour-matched Trimets for securing the mesh to the gutter lip
- Purpose-built DEKAFast saddles designed for Dek 762 ribs
- All necessary hex-head screws
How to Install Gutter Guard on Dek 762 Roof
Fitting the Leaf Stopper DEK762 system is a manageable DIY project if you are confident working safely at height. The steps below provide a general overview of how the system is installed.
- Preparation: Before you begin, ensure you have the right safety equipment, including gloves, safety glasses, and a secure ladder. Thoroughly clean leaves, debris, and silt from your gutters and downpipes.
- Step 1: Secure the Mesh to the Gutter Edge: Unroll the mesh along the gutter. Place a Trimet over the mesh and onto the outer lip of the gutter. Fasten it in place using the provided screws, ensuring the mesh is held firmly. Continue this process along the gutter edge.
- Step 2: Make Expansion Cuts for the Ribs: Lay the mesh over the roof surface. Where the mesh meets the ribs of the Dek 762 profile, use tin snips to make expansion cuts so the mesh can sit correctly around the rib shape.
- Step 3: Fasten the Mesh with DEKAFast Saddles: With the mesh positioned correctly, place a DEKAFast saddle over the mesh directly on top of the roof rib. The saddle is shaped to suit the DEK762 profile. Secure the saddle using the provided hex-head screws. Repeat along the roof edge.
- Final Inspection: Once all saddles are fastened, check the full length of the installation for any gaps or loose sections. The mesh should be secure across the run and positioned to help keep leaves and debris out of the gutter.
Tools You Will Need
You don't need a specialised toolkit to install the DEK762 system. The essential items are:
- Required: Cordless drill with a hex socket, good quality tin snips, gloves, eye protection, and safe ladder access.
- Why use the right socket: Using the correct hex socket helps prevent stripping screw heads and supports a secure fastening.
- Safety first: Always work safely on a roof. Ensure your ladder is stable, wear appropriate footwear, and avoid working in wet or windy conditions.
For easier future inspection and cleaning, many customers also install an EasyAc access panel, allowing easier access to the gutter when maintenance is required.
Bushfire Safety and Material Durability
Protecting your home involves more than just keeping leaves out. In Australia, bushfire preparation is an important consideration for many roof and gutter systems.
- Understanding BAL ratings: If your property is in a designated Bushfire Attack Level zone, suitable materials and compliant installation may be required.
- When to choose Fine Mesh: Fine Mesh is designed for ember protection and is the only mesh in the Leaf Stopper range that is BAL-rated.
- The benefits of non-combustible aluminium: Standard, Premium and Fine Mesh are all aluminium mesh options. Aluminium is non-combustible and suited to demanding Australian conditions.
- Long-term resilience: Leaf Stopper products are designed to provide durable, long-term gutter protection when installed and maintained correctly.

BAL Compliance Explained
In a bushfire, flying embers can travel ahead of the fire front and may ignite combustible debris trapped in gutters. A suitable gutter guard system can form part of a broader bushfire preparation strategy.
Only Leaf Stopper Fine Mesh meets the strict aperture requirements required for BAL-rated applications. To learn more about preparing your property, read our guide to bushfire protection.
Aluminium vs Plastic Gutter Guards
Plastic gutter guards may seem like a cheaper option, but they are generally less suited to harsh Australian conditions. Plastic can become brittle and crack under ongoing UV exposure.
Powder-coated aluminium is a stronger long-term choice, offering durability, non-combustibility, and a clean aesthetic that can be colour-matched to your Colorbond® roof.

The DEK762 kit is available with Standard Mesh, Premium Mesh and Fine Mesh options. Standard and Premium Mesh use a 3.5mm aperture, while Premium Mesh is manufactured from thicker aluminium for increased durability. Fine Mesh is designed for excluding smaller debris and is the only BAL-rated mesh option in the Leaf Stopper range.
How do I know if my roof is DEK762 or Trimdek?
DEK762 and Trimdek are very similar roof profiles commonly used throughout Australia. If you are unsure, compare your roof profile dimensions with manufacturer specifications or contact Leaf Stopper before ordering.
Can I install the DEK762 kit myself?
Yes. Many customers install DEK762 kits themselves using basic tools such as a drill, tin snips and a ladder. Always follow safe working practices when working at height.
Do gutter guards eliminate gutter cleaning?
No gutter guard system is completely maintenance-free. However, a properly installed gutter guard can help reduce the amount of leaves and debris entering the gutter and may reduce how often cleaning is required.
Is the DEK762 system suitable for bushfire-prone areas?
Fine Mesh is the only BAL-rated mesh option in the Leaf Stopper range. If bushfire protection is important for your property, consider selecting Fine Mesh and review local building requirements.
Can I still access my gutters after installation?
Yes. Many customers install an EasyAc access panel to make future gutter inspections and cleaning easier without removing large sections of mesh.
