Frequently Asked Questions (FAQs)

Colorbond Steel is a durable, pre-painted steel product manufactured by BlueScope in Australia. It is designed for a wide range of applications, including roofing, wall cladding, fencing, gutters, and other construction projects.

Colorbond steel is primarily made from Zincalume® steel, which is a combination of steel, aluminum, and zinc.

  • Zincalume® steel is coated with a layer of zinc-aluminum alloy, providing excellent corrosion resistance.
  • Over this base layer, Colorbond applies a baked-on painted finish using high-quality pigments and a durable resin to enhance both its aesthetics and protection from the elements.
This construction makes Colorbond Steel lightweight, durable, and resistant to rust and weathering, perfect for outdoor use like roofing, cladding, and fencing.

1. Corrosion Resistance

  • The Zincalume® steel base (a mix of zinc and aluminum) provides excellent protection against rust and corrosion, even in coastal and harsh weather conditions.
  • Colorbond steel is designed to withstand extreme temperatures, heavy rainfall, and saltwater exposure, making it ideal for both urban and coastal environments.
2. Weather Resistance
  • The baked-on paint finish is engineered to resist fading, chipping, and peeling, even under prolonged sun exposure.
  • It can handle harsh UV rays, rain, and wind, retaining its color and finish for many years.
3. Scratch & Impact Resistance
  • Colorbond has advanced coatings that resist scratches, abrasions, and impacts, making it suitable for high-traffic areas and environments where durability is critical.
4. Fire Resistance
  • Colorbond is fire-resistant and does not contribute to the spread of fire, making it a safe choice for fire-prone areas.

A Colorbond steel roof is celebrated for its impressive longevity, often lasting 30 to 40 years or more. Several key factors affect its lifespan:

  • Environmental conditions: Coastal areas and harsh climates demand more regular maintenance to combat corrosion and wear.
  • Product type:Options like Colorbond Ultra offer enhanced protection against the elements, especially in coastal environments.
  • Installation quality: Expert installation is crucial; a well-installed roof can withstand the test of time.
  • Maintenance: Regular cleaning and debris removal are essential for maintaining both aesthetics and durability.
With proper care and consideration, a Colorbond steel roof can provide a resilient and beautiful shelter for decades.

You should consider replacing your Colorbond roof if you notice any of these signs: 1. Visible Rust or Corrosion

  • While Colorbond is designed to resist rust, prolonged exposure to extreme conditions (like coastal salt or damage) can still cause corrosion. If you see rust patches or flaking, it's a sign to inspect it more closely.
2. Fading or Peeling Paint
  • If the paint is starting to peel or fade significantly, it could affect the roof’s protective layer. Though Colorbond is UV resistant, excessive fading or chipping might indicate a need for replacement, especially if the integrity is compromised.
3. Leaks or Water Damage
  • If you notice water stains inside your home or if the roof is leaking despite repairs, it may be time to replace it. This could be a sign of significant wear or damage to the steel panels.

Maintaining a Colorbond roof is relatively easy due to its durability and weather resistance. Here’s how to keep it in top condition:

1. Regular Cleaning

Remove debris – Clear leaves, twigs, and dirt from the roof and gutters to prevent water buildup.

Wash the surface – Use a hose with clean water to remove dust and dirt. For stubborn grime, mix mild detergent with water and use a soft-bristled brush. Avoid harsh chemicals.

Avoid pressure washers – High-pressure water can damage the protective coating. Stick to low-pressure washing.

2. Check for Damage

Inspect for scratches, dents, and rust – Minor scratches aren’t a big concern, but deep ones may need touch-up paint to prevent corrosion.

Look for loose screws or fasteners – Tighten any that have come loose over time.

Check for leaks – Inspect your ceiling for water stains, which may indicate a leak that needs fixing.

3. Prevent Moss & Algae Growth

If your roof is in a damp or shaded area, moss and algae can grow. Use a solution of water and mild bleach (1:4 ratio) to gently clean affected areas. Rinse thoroughly afterward.

4. Maintain Gutters & Drainage

Clean gutters & downpipes: Blocked gutters can cause water to pool, leading to corrosion. Clean them at least twice a year.

Ensure proper drainage. Water should flow freely off the roof to avoid long-term damage.

5. Repainting & Touch-Ups

If the color fades or minor rust appears, use Colorbond-compatible touch-up paint. For major repainting, consult a professional.

6. Professional Inspection (Every 2–3 Years)

If unsure about your roof’s condition, hire a professional to inspect and perform necessary repairs


The cost of Colorbond roof replacement varies depending on several factors, including the size of the roof, labor costs in your area, and the complexity of the installation. Generally, you can expect it to be more expensive than basic metal roofing but more affordable than premium materials like slate or terracotta tiles.

Factors Affecting Cost:

Roof Size & Pitch: The size and angle of your roof greatly impact the cost of a roofing project. Larger roofs require more materials and labor, while steep pitches may complicate installation. However, experienced contractors are equipped to handle these challenges safely.

Type of Colorbond Roofing: There are numerous Colorbond roofing options, each with unique benefits. Choose from standard finishes for a classic look or ultra finishes for durability and weather resistance. Matte finishes offer a modern vibe but may cost more. Your choice affects lifespan and maintenance, so pick one that aligns with your style.

Removal of Old Roofing: If your old roof needs removal, be prepared for additional costs and labor. Though it can be intensive, it's an investment in your home's future, laying a solid foundation for your new roof.

Additional Features: Consider enhancements like insulation, effective guttering, flashing, and proper ventilation. While they may influence your budget, they add value and improve the roof's durability and functionality.

Labor & Location: Labor costs vary by location and contractor expertise. Urban areas may have higher prices due to demand. Get quotes from several local roofing professionals to compare services and ensure the best value for your roofing project. Happy roofing!

Installing a Colorbond roof yourself is possible, but it’s a complex job that requires the right skills, tools, and safety measures. If you have experience with roofing or construction, you might be able to handle a small, straightforward project. However, for most people, professional installation is recommended to ensure durability, waterproofing, and compliance with building codes.
