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 results in poor contact, mesh sagging, and gaps that defeat the purpose of a gutter guard.
- The role of the DEK762 system: Our system is engineered exclusively for this profile. It uses purpose-manufactured DEKAFast saddles that clip perfectly over the ribs, ensuring the mesh is held securely and tautly 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 a complete installation.
Why Profile Matching Matters
Achieving a long-lasting and effective result depends entirely on using components that match your roof's specific dimensions. The DEK762 system is precisely 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 embers. Our system ensures a seamless, integrated fit that looks professional and performs reliably in demanding Australian conditions.
A secure fit is essential for preventing water from entering your roof space and causing internal damage.

The Leaf Stopper Advantage
When you choose Leaf Stopper, you're investing in a system designed by experts for local conditions. Our products are the result of decades of innovation and refinement.
- 100% Australian owned and invented: We understand Australian roofs and the challenges they face, from torrential rain to harsh sun.
- CSIRO certified and award-winning design: Our materials and designs are tested to the highest standards for performance and durability.
- Focus on durability: We use powder-coated aluminium for all components, ensuring they won't rust, burn, or degrade under UV exposure like plastic alternatives.
Choosing the Right DEK762 Kit: Mesh Options & Coverage
The Leaf Stopper DEK762 system is designed for a perfect fit, so choosing your kit is straightforward. You don't need to worry about complex fastener calculations; the primary decisions are selecting the right mesh type and ensuring you have enough material to cover your gutters.
-
Step 1: Choose Your Mesh Type. We offer three grades of high-quality aluminium mesh to suit different environments:
- Standard Mesh: Ideal for general leaf protection from large and medium trees.
- Premium Mesh: A finer weave perfect for protecting against smaller debris like pine needles.
- Fine Mesh: Our finest option, designed for excluding very small debris and providing protection against ember attack in fire-prone areas. It is the only mesh in our range that is compliant for use in BAL-rated zones.
- 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. Simply measure the total length of the gutter edges you need to protect. Our DEK762 kits are available in various lengths, allowing you to order exactly what you need for your project.
What's Included in a DEK762 Kit?
Every Leaf Stopper DEK762 kit comes with all the components required for a professional DIY installation. You’ll receive:
- Your chosen length and width of Aluminium Mesh Shield
- Colour-matched Trimets for securing the mesh to the gutter lip

How to Install Gutter Guard on Dek 762 Roof
Fitting the Leaf Stopper DEK762 system is a manageable DIY project that delivers a professional-grade result. Follow these steps for a secure and tidy installation that will help reduce gutter cleaning for years to come.
Just as you can take control of your gutter maintenance, you can also simplify your garden care; learn more about Garden Watering to see how easy-to-install irrigation systems can keep your lawn and flowerbeds in top condition.
- Preparation: Before you begin, ensure you have the right safety equipment, including gloves, safety glasses, and a secure ladder. Thoroughly clean all 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, placing Trimets approximately 300-400mm apart along the entire length of the gutter.
- Step 2: Make Expansion Cuts for the Ribs: Lay the mesh flat over the roof surface. You will see that the mesh puckers where it meets the tall ribs of the Dek 762 profile. Using tin snips, make a straight cut in the mesh from the back edge towards the gutter, stopping just short of the flat pan section. This "expansion cut" allows the mesh to lay flat on either side of the rib.
- Step 3: Fasten the Mesh with DEKAFast Saddles: With the mesh now sitting flush against the roof, take a DEKAFast saddle and place it over the mesh directly on top of a roof rib. The saddle is shaped to fit the rib profile perfectly. Secure the saddle to the rib using the provided hex-head screws. Repeat this for every rib along the roof edge.
- Final Inspection: Once all saddles are fastened, walk the length of the gutter and check for any gaps or loose sections. Ensure the mesh is taut and secure across the entire run, leaving no entry points for leaves or vermin.
Tools You Will Need
You don't need a specialised toolkit to install our DEK762 system. The essential items are:
- Required: A cordless drill with a hex socket, good quality tin snips, and appropriate safety gear (gloves, glasses).
- Why use the right socket: Using the correct hex socket (available in our online store) prevents stripping the screw heads and ensures a secure fastening every time.
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 those working on rural properties or remote sites, using a system like Jobcam can also help maintain site security and protect your equipment throughout the installation.
Bushfire Safety and Material Durability
Protecting your home involves more than just keeping leaves out. In Australia, bushfire safety is a critical consideration for any roofing product. Our gutter guards are made from non-combustible materials designed to withstand harsh local conditions.
- Understanding BAL ratings: If your property is in a designated Bushfire Attack Level (BAL) zone, you must use building materials that comply with Australian Standards.
- When to choose Fine Mesh: Our Fine Mesh is specifically designed to meet these standards and is compliant for use in all zones from BAL-12.5 to BAL-FZ (Flame Zone). It helps prevent embers from accumulating in your gutters, which is a common source of house fires during a bushfire.
- The benefits of non-combustible aluminium: Unlike plastic or foam products, our powder-coated aluminium mesh will not burn, melt, or degrade under the Australian sun. This ensures reliable, long-term performance.
- Long-term resilience: We back our commitment to quality with a 15-year product guarantee, giving you confidence and peace of mind.
BAL Compliance Explained
In a bushfire, flying embers can travel kilometres ahead of the fire front and ignite flammable debris trapped in your gutters. A compliant gutter guard system forms a crucial part of your home's defence. Only our Fine Mesh meets the strict aperture requirements of less than 2mm needed for BAL compliance. To learn more about protecting your property, read our guide to bushfire protection requirements.
Aluminium vs Plastic Gutter Guards
While plastic gutter guards may seem like a cheaper option, they are not suited to Australian conditions. Plastic becomes brittle and cracks under constant UV exposure, often failing within a few years. Powder-coated aluminium is a far superior investment, offering durability, non-combustibility, and a clean aesthetic that can be colour-matched to your Colorbond® roof. For those considering different roofing materials, Pro Torch Roofing provides a detailed look at the advantages of metal systems compared to shingles.
