| Upfront installed cost | $4.50-$8.50 USD per sq ft for asphalt shingles in the GeoQuote roof-cost model. | $5-$12 USD per sq ft for exposed-fastener steel and $9-$16 USD per sq ft for standing seam in the GeoQuote metal-roof model. | Asphalt is usually cheaper upfront. Standing seam metal often costs roughly 2x the common asphalt planning range before roof-specific adjustments. |
| Canadian 1,800 sq ft planning range | C$11,000-C$16,500 CAD for a typical architectural-shingle planning range before GST/HST, PST, permits, decking, disposal, and contractor scope. | C$13,700-C$27,400 CAD for exposed-fastener steel and C$19,200-C$38,400 CAD for standing seam before GST/HST, PST, permits, decking, or final scope. | Canadian metal roof searches need visible CAD ranges and GST/HST context, not only USD calculator output. |
| Lifespan | Architectural shingles commonly model around 25-30 years in the GeoQuote calculator. | Metal roofing commonly models around 40-70 years for standing seam and 30-50 years for corrugated metal. | Metal can win long-term ownership when the homeowner expects to stay long enough to benefit from the longer roof life. |
| Total cost of ownership | A 50-60 year planning window can require one or two asphalt replacements depending on material, climate, ventilation, and installation quality. | A 50-60 year planning window may be covered by one metal roof on many homes, but paint finish, fastener system, snow load, and coastal exposure still matter. | Asphalt wins the first bill. Metal can win the long-hold math if the owner values lifespan, lower replacement frequency, and durability. |
| Best fit | Budget-sensitive replacement, resale-prep projects, standard residential roofs, and homeowners who want the lowest first cost. | Long-hold homes, snow country, premium exterior upgrades, wildfire or hail-conscious markets, and homeowners who want durability over lowest first cost. | The better choice depends on cash budget, ownership horizon, climate, and final contractor scope. |
