How long does a metal roof last?

Typically 40 to 70 years, far longer than asphalt's 20–25. That longevity, plus fire and snow performance, is the main appeal despite the higher upfront cost.

Is a metal roof worth the cost?

It costs about two to three times asphalt upfront but can last two to three times as long, with better fire and snow performance — strong value over the long term.

Metal roofing has grown popular for its longevity and looks. It costs more upfront than asphalt, so it's worth understanding the trade-offs before deciding.

The advantages

Metal roofs last far longer than asphalt — often 40 to 70 years — shed snow and rain well, resist fire, and are recyclable. In snowy and fire-prone areas (much of BC), those are real benefits. They're lightweight and can sometimes go over an existing roof.

The trade-offs

The upfront cost is roughly two to three times asphalt. Metal can be noisier in rain without proper underlayment and insulation, can dent from large hail, and needs installers experienced with metal — a poor install leaks. Expansion and contraction must be allowed for.

Styles

Standing-seam metal (concealed fasteners) is premium and sleek; exposed-fastener panels are cheaper but the fasteners need eventual maintenance. Metal also comes in shingle and tile-look profiles for a more traditional appearance.
