Choosing the right roofing material is one of the most important decisions in any residential or light commercial build. Builders and homeowners alike must balance durability, aesthetics, cost, and long-term performance especially in Australia’s varied climate.
Two of the most commonly compared options are asphalt shingles and metal roofing. This guide breaks down the key differences to help you determine which solution best suits your project.
Overview of Both Roofing Systems
Asphalt shingles
Asphalt shingles are a highly popular roofing choice in North America and are gaining strong traction in Australia. Made from a fibreglass mat coated with asphalt and mineral granules, they offer a layered, architectural finish that suits both traditional and contemporary homes.
Modern asphalt shingles are engineered for strength, weather resistance, and visual appeal, with profiles designed to replicate slate or timber shake.
Metal Roofing
Metal roofing systems are typically manufactured from Colorbond® steel, zinc, or aluminium. Known for their strength and longevity, metal roofs are widely used across Australia and are particularly popular in contemporary and coastal builds.
Metal roofing is usually installed in long sheets or panels and offers a clean, modern aesthetic.
Cost Comparison
Upfront Costs
- Asphalt shingles generally have a lower upfront material cost and can be cost-effective on complex roof designs.
- Metal roofing often has a higher initial cost, particularly for premium profiles or thicker gauges.
Installation Costs
- Asphalt shingles generally have a lower upfront material cost and can be cost-effective on complex roof designs.
- Metal roofing often has a higher initial cost, particularly for premium profiles or thicker gauges.
Durability & Lifespan
Upfront Costs
- Asphalt shingles: Typically last 25–40 years depending on product quality, installation, and maintenance.
- Metal roofing: Can last 40–70 years with proper installation and care.
Performance in Australian Conditions
Heat & Noise
- Asphalt shingles provide natural sound insulation, making them quieter during rain and hail.
- Metal roofing can amplify noise without proper insulation layers.
Wind & Weather
- High-quality asphalt shingles are designed to resist strong winds and heavy rain when installed to specification.
- Metal roofing performs well in extreme weather but can be more susceptible to denting from hail.
Bushfire Considerations
- Premium asphalt shingles meet Class A fire ratings, the highest available.
- Metal roofing is non-combustible but must be paired with compliant underlays and detailing.
