Manitoba winters are a serious test for any roof, deep snow loads, freeze-thaw cycles, ice dams, and the odd −40 cold snap. Two materials dominate the conversation here: asphalt shingles and metal roofing. Both can perform beautifully when installed correctly. Here’s how they compare for our climate.
Upfront cost
Asphalt shingles win on price. A quality architectural-shingle roof costs significantly less upfront than a comparable standing-seam metal roof, often less than half. If budget is the deciding factor, asphalt is the practical choice.
Metal costs more to install, partly for the material and partly for the specialized labour it requires.
Lifespan
This is where metal pulls ahead. A standing-seam metal roof can last 50 years or more. Quality architectural asphalt shingles in Winnipeg typically last 25-30 years. Over the very long run, metal can be cost-competitive, but only if you stay in the home long enough to benefit.
Snow and ice
Metal sheds snow well, which reduces load and can limit ice-dam buildup. The flip side: sliding snow can come off in sudden sheets, so snow guards are often needed over doors and walkways.
Asphalt holds snow more evenly. The real key to preventing ice dams with either material isn’t the roof surface, it’s proper attic ventilation and insulation, plus ice & water shield along the eaves. Get those right and asphalt handles our winters just fine.
Looks and noise
Asphalt offers dozens of colours and a classic, low-key look that suits most Winnipeg homes, and we bring physical samples so you can choose in natural light. Metal gives a modern, distinctive profile. Worried about rain noise on metal? With proper decking and underlayment, it’s quieter than people expect.
So which should you choose?
- Choose asphalt if you want the best value, a wide range of colours, and proven performance, it’s the right call for most homes.
- Choose metal if you’re planning to stay long-term, want maximum lifespan, and like the modern look.
There’s no universally “best” roof, only the best roof for your home, budget, and timeline. Get in touch and we’ll walk you through both honestly.
