In reality, your roof influences your energy consumption every day. That\u2019s exactly where metal makes a real difference. Metal surfaces reflect a large portion of solar radiation. In summer, your attic therefore stays cooler than with dark shingles. Indeed, asphalt shingles can reach 70\u00b0C in full sun. They then transfer this heat into the house. A light-coloured metal roof combined with good insulation therefore reduces the demand for air conditioning. In winter, this same insulation limits heat loss through the roof. As a result, you use less energy to heat and cool your home. Using less energy also means producing fewer greenhouse gases. Every kilowatt-hour saved frees up capacity for other uses. In Quebec, even though hydroelectricity dominates, reducing consumption still benefits the shared grid. Learn more about energy-efficient roofs. Compatibility with solar panels A metal roof is the ideal surface for installing solar panels. This combination concretely strengthens the environmental impact of a metal roof even further. Indeed, mounting systems for standing seams require no drilling. The clamps grip directly onto the metal ribs. No holes, no risk of leaks. The installation therefore remains clean and reversible. In addition, the lifespan of a metal roof exceeds that of the solar panels. As a result, you\u2019ll never have to remove your panels to replace the roof covering. With a shingle roof, however, this costly removal inevitably happens after 15 to 20 years. By combining a metal roof and solar panels, you reduce your dependence on fossil fuels. You thus produce clean electricity while protecting your home. In short, it\u2019s a doubly responsible approach. Manufacturing: an impact worth putting into perspective Let\u2019s be transparent. Steel manufacturing consumes energy and produces CO2 emissions. This industrial process is therefore not environmentally neutral. In fact, it\u2019s the main argument against metal. However, this initial cost needs to be put into perspective. Indeed, the energy used to manufacture a single metal roof remains lower than that of three or four shingle roofs. A complete life cycle analysis therefore clearly favours metal. In addition, the steel industry is evolving rapidly. Manufacturers in particular are adopting less energy-intensive processes every year. The SSAB steel used by Metal Roof Canada comes from European plants with very strict standards. In fact, according to a Natural Resources Canada report, improving the building envelope is one of the most effective ways to reduce residential carbon footprints. Gutters and accessories: completing the cycle However, an environmental approach doesn\u2019t stop at the roof panels. Indeed, gutters, flashing and accessories also contribute to the overall footprint. In particular, Metal Roof Canada offers steel gutters with a 50-year warranty. Like the roof panels, they are fully recyclable at the end of their life. They therefore eliminate the frequent replacements that vinyl gutters undergo. An all-metal system thus maximizes the environmental consistency of your project.
