If you're trying to decide between metal and asphalt, you're going to hear strong opinions on both sides — usually from people selling one or the other. Here's the honest comparison.
Metal vs shingle roofs: what's the difference?
Metal roofs are constructed from materials like aluminum, steel, or copper alloys and come in an array of colours, styles, and shapes — with the ability to mimic the appearance of wood and slate. These systems offer exceptional durability, with lifespans reaching 50 to 100 years when properly installed and maintained. The reflective properties of metal roofing actually help regulate indoor temperatures rather than increasing heat.
The sustainability factor sets metal roofing apart significantly. These products contain at least 25% recycled materials and are fully recyclable at end-of-life. In contrast, asphalt shingles are petroleum-based products that cannot be recycled, resulting in billions of pounds in landfills every year as homeowners replace them every 15 to 20 years.
How much does a metal roof cost vs shingles?
Metal roofing requires higher initial investment due to its longevity and the specialized training needed for proper installation. However, the extended lifespan means a properly installed metal roof can last as long as the house itself and will cost you less in the long run. Asphalt offers lower upfront costs and is widely available, often costing half as much initially — but frequent repairs accumulate expenses, potentially negating the initial savings advantage.
Do metal roofs leak more than shingles?
Metal roofing systems actually feature fewer vulnerability points than traditional shingles. Properly installed metal roofs contain significantly less water exposure points compared to traditional shingled roofs because they use concealed fastener systems with minimal or no exposed hardware. Professional installation is crucial — expert installers understand local weather challenges and employ quality materials to ensure your roofing system maintains its integrity for decades.
Which option is better for your home?
Both materials have distinct advantages, and the optimal choice depends on individual circumstances. Installing metal roofing over existing asphalt shingles is possible, saving time and labour costs compared to complete teardown. Ultimately, the decision hinges on your immediate requirements, aesthetic preferences, budget constraints, and long-term plans for your property — but if you're staying in the house for 10+ years, metal almost always wins on lifetime cost.
