The Ultimate Guide to Zincalume Flashing Right Angle: A Review

Choosing the right roofing material can be daunting. Zincalume flashing delivers with its superior durability and ease of handling. In this article, we’ll explore the qualities that make zincalume flashing a practical choice for builders and reveal tips for a smooth installation. Gain insights into how it stacks up against the elements and understand its place in the cost spectrum of roofing materials.

Key Takeaways

  • Zincalume flashing is highly durable and weather-resistant, boasting up to four times the lifespan of galvanized steel in similar conditions, and is identifiable by distinct traceability markings.

  • Suitable for both professional and DIY projects, Zincalume offers easy installation, minimal maintenance, and significant long-term cost savings due to its corrosion-resistant alloy composition.

  • While Zincalume flashing is compatible with various roofing materials and customizable for specific design needs, it should not be used in direct contact with copper or lead to avoid accelerated corrosion.

Unveiling the Zincalume Flashing Elegance

With a claim to fame of being produced using 100% Australian steel from BlueScope’s brands, Zincalume flashing makes a bold entrance into the roofing market. Its core selling point? Durability. The manufacturers assert minimal maintenance and a performance capable of withstanding severe weather, backed by BlueScope’s high-quality assurance and performance testing. The question is, can it live up to its claims? We’ll be putting that to the test.

Traceability is another feather in the cap of Zincalume flashing, including barge board and fascia installations in building projects. Each panel is marked with the Zincalume logo, batch number, date, and certification markings on its underside, ensuring complete traceability. This allows professionals to easily identify the product's authenticity, just like checking the label on an apron or verifying a download source at a junction of information exchange. The length of each panel is also marked, providing additional information for proper installation.

But who else stands to benefit from Zincalume? Let’s find out.

The Audience for Alloy - Who Benefits from Zincalume?

Example of Zincalume flashing and Corrugated Iron

Zincalume flashing is not just for professionals. While it’s true that professional roofers often choose Zincalume for its long-term durability and compliance with high safety and regulation standards, do-it-yourself enthusiasts also find it appealing. The ease of installation, minimal maintenance requirements, and superior resistance to corrosion compared to other materials make Zincalume an attractive choice for DIY projects.

Both professional roofers and DIY enthusiasts can benefit from Zincalume’s efficient thermal performance and energy savings. But what makes this material so durable and easy to use? Let’s peel back the layers in the next sections.

Material Mastery - The Durability Debate

Zincalume flashing is made from a zinc and aluminium alloy coating known for its corrosion resistance and durability. Thanks to this aluminium-zinc alloy coating, Zincalume flashing can outlast galvanized steel in similar environmental conditions by up to four times. This makes it an undeniably durable roofing option that stands the test of time.

Furthermore, the coated surface of Zincalume reduces the need for maintenance, making it a long-term, hassle-free roofing choice. Consider its potential lifespan of up to 50 years for metal roofing like Zincalume, and you begin to see the long-term savings in maintenance and repair costs.

With good abrasion resistance due to its hard surface, it’s reliable in roof areas that might encounter debris or require a higher level of mechanical endurance. The steel core of Zincalume flashing aids in its overall strength and resilience, helping it to preserve its form and function longer.

Functional Finesse - Using Zincalume with Ease

Zincalume flashing is not just durable and waterproof; it’s also versatile. It’s suitable for roofing, walling, and cladding applications. The innovative design of Zincalume flashing contributes to its low maintenance needs, making it an ideal choice for effective rainwater management.

What about the installation process? Fear not. The installation of Zincalume flashing is straightforward, thanks to its compatibility with a range of fastening methods. This caters to different roofing techniques and installer preferences.

But what happens when Zincalume is put under the scrutiny of real-world conditions? Let’s find out.

Real-World Resilience - Zincalume Under Scrutiny

Zincalume flashing is a warrior in the face of harsh environmental conditions. Its composition provides substantial resistance to corrosion, making it highly suitable for severe environmental conditions, including high temperatures and saline coastal areas.

Furthermore, Zincalume employs a sacrificial mechanism, which means the exposed steel beneath is shielded from corrosion even if it gets scratched. This adds to the durability and long-term appearance of the flashing. However, no product is perfect. Despite its resilience, Zincalume should not be used directly with copper or lead due to the risk of accelerated corrosion, indicating some material limitations.

Customization and Compatibility

One of the great advantages of Zincalume flashing is its customization options, including custom flashings. It’s available in standard sizes and can be ordered in custom dimensions to meet specific roofing requirements. This includes various design options and modifications, such as considering angles, hooks, and measurements specific to intricate roofing structures.

But it’s not just about customization. Zincalume flashing also offers broad compatibility with different roofing materials, such as metal, concrete, or steel roofs. It works with right-angle structures and angle flashing for roof penetration flashings.

Now, you might be wondering, is Zincalume worth the investment?

The Roofing Revolution - Is Zincalume Worth It?

Metal roofing in Australia, which includes Zincalume, falls within a price range of $50-$180 per square metre. This variance is due to factors such as:

  • Material type

  • Roof profile

  • Size

  • Thickness

  • Finish

While Zincalume is a mid to high-range pricing option in roofing materials, it offers significant long-term performance benefits.

The resistance to wear and tear of Zincalume flashing contributes to its long-term performance advantages, reducing the need for frequent maintenance. Couple this with its durability that requires minimal maintenance, and you begin to see the cost savings compared to potential repairs from damage like leaks.

But what about style? Can Zincalume flashing suit your aesthetic preferences?

Matching Your Style - The Aesthetic Adaptability of Zincalume

Zincalume steel can be custom-painted to fit various aesthetic preferences, achieving an attractive finish. You can personalise your style by applying good quality water-based Acrylic paint after cleaning the new surface to remove any roll-forming lubricants.

However, it’s crucial to consult the paint manufacturer regarding the primer needs, especially for surfaces intended for drinking water collection. For aged Zincalume steel, thorough cleaning, grease removal, and wire brushing to remove loose corrosion are necessary before applying the Acrylic paint.

High-quality roof paints, such as acrylic-based paint, specifically formulated to withstand harsh weather conditions, can ensure the longevity and visual appeal of painted zincalume roof flashing and roof sheeting. Products like the Roofbond Roof Membrane by Shieldcoat, offer warranties up to 15 years and are available in a wide range of colors for personalization.


In conclusion, Zincalume flashing, with its durability, versatility, and customization options, offers a compelling choice for both professional roofers and DIY enthusiasts. Despite its mid to high-range pricing, its long-term performance benefits and minimal maintenance requirements make it a cost-effective roofing solution.

However, it’s important to remember that Zincalume is highly corrosion-resistant and should not be used directly with copper or lead. And if aesthetics are a priority, the option to paint Zincalume to match any colour palette certainly adds to its appeal.
