Metal vs Asphalt Roofing in Victoria, BC

Walk the region and you can see where each material is winning. Metal is going on as the second roof in the Highlands, on the water side of Cordova Bay and Dallas Road, and in Broadmead where thirty-year-old Garry oaks and Douglas firs now shade whole slopes. Laminate asphalt still dominates the simple gables of Gordon Head, Langford and Westhills, where the sun reaches the roof, the pitch is easy and a crew can finish in two days. The choice tracks the tree canopy more than the postal code.

Roof shape changes the gap between the two quotes. On a plain rancher the metal premium is at its smallest. On a cut-up Fairfield or Oak Bay roof with dormers, valleys, two chimneys and a skylight, metal detailing is slow and skilled, and the premium grows. A material change may also be the one re-roof a building department wants to hear about; no Greater Victoria municipality publishes an online rule, so phone before you sign (City of Victoria 250-361-0344, Saanich 250-475-5457). Heritage-designated homes should expect a look-and-profile conversation as well.

The honest way to compare the two is cost per year. Take the model ranges above: asphalt at $6,900 to $12,600 over 20 to 30 years works out to roughly $230 to $630 a year; metal at $15,100 to $30,200 over 40 to 60 years is roughly $250 to $755 a year. In other words, they overlap. Metal is not cheaper per year in most cases, but it is not the luxury it looks like on the invoice either.

What tips the balance is everything that is not on the invoice. A shaded asphalt roof in Saanich needs professional moss treatment every 12 to 18 months, which Shoreline Roofing's 2026 moss guide puts at $500 to $1,200 a visit. Over a 40-year horizon an asphalt roof is torn off and replaced once more, at whatever prices apply in the 2040s, with a second round of disposal and disruption. Metal skips both. If you will sell in five years, none of that accrues to you.

Laminate shingles remain the right answer for a large share of Greater Victoria roofs, and the reasons are practical rather than aesthetic.

• The roof gets sun for most of the day and moss has never been a problem
• You expect to sell within about ten years; a new roof recoups about 60–70% of its cost at sale, so the cheaper roof loses less
• The roof is cut up with dormers, valleys and penetrations, where metal detailing costs climb fastest
• Budget is the constraint: the asphalt range starts at less than half the metal range
• You want the widest choice of crews; most local roofers install laminate shingles every week

Metal makes the most sense where asphalt is expected to fail early. North-facing slopes under Douglas fir or cedar, lots in the Highlands, Metchosin or Prospect Lake, and the shaded side of a Broadmead house are the classic cases: moss holds water against shingles and shortens their life, while a metal roof sheds it. Waterfront and exposed sites in Sidney, Cordova Bay and along Dallas Road add wind and salt, which lift shingle tabs and corrode ordinary fasteners.

The condition is that the metal is specified for the coast. The Metal Roofing Alliance's guidance favours aluminum or higher-grade coated steel and matching fasteners where salt spray reaches the roof; a bargain galvanized panel with exposed screws in a salt zone can underperform a good shingle.

Comparing a metal quote with an asphalt quote only works when both describe the same scope. Ask each contractor to state the following in writing.

• Roof area in squares, so you can compare price per square foot
• Exact product line, gauge or shingle weight, colour and both warranties (product and workmanship)
• Underlayment type; metal normally needs a high-temperature synthetic
• How walls, chimneys and skylights will be flashed (new metal, not sealant)
• Number of existing layers to remove and the decking allowance per sheet
• Whether the contractor has confirmed permit requirements with the municipality for a material change
