Metal Roof Cost vs Asphalt Shingle Cost

Have you had a quote for regular asphalt shingles? If you’re completely new to metal roofing you may just want to understand in ballpark terms what the investment will be…

In Ontario, a reputable roofing company (with WSIB and liability insurance) charge from $3-4/sqft for an asphalt roof. The average price range on an entry level residential metal roofing system in Ontario is $6-7/Sqft. In other words, a metal roof is about twice the initial cost of an asphalt roof.

METAL ROOFING COST BY PRODUCT TYPE

There are 4 main categories of metal roofing in Ontario: Exposed Fastener, Concealed Fastener, Standing Seam and Agricultural Panels. The list below explains the characteristics, options and typical prices of each. Price to install in Ontario is provided in tables at the end of each description.

Note: If you are a DIY expert and want an idea on how much materials will cost budget for about 1/2 of listed installed prices. Labour makes up a significant portion of the total price as installation requires skilled contractors with metalsmithing abilities.

1. Exposed Fastener Metal Roofing System (Sheet Metal Panels)

Example of an exposed fastener metal roof installed on wood strapping.

 

Exposed fastener metal roofing systems are commonly used on suburban homes in Ontario. As the name suggests, the fasteners (screws) are exposed. Screwed through the surface of the metal panels, these metal roofs are installed over battens or wood strapping. The panels overlap on all sides. These metal roofs have the following major advantages of a metal roof.

 

Advantages

  • permanent roofing material
  • energy efficient
  • recycled/recyclable content
  • high speed wind resistant
  • fire resistant
  • hail resistant
  • pest resistant
  • does not support fungus/organic growth
  • less expensive than asphalt shingles over time

In addition to having all of the major benefits a metal roof can offer, an exposed fastener metal roofing system has the following extra advantages.

Exposed Fastener Extra Advantages

  • can square up the appearance of a sagging roof

 

Locally Available Materials: galvanized steel, galvalume steel and aluminum.*

*Note: it is generally not recommended to install aluminum over strapping because it is a softer metal and can bend over the gaps if stepped on.

Locally Available Finishes: pre-painted SMP, PVDF and stone coated (textured).

Locally Available Styles: metal tile, metal shake, metal shingle.

2. Concealed Fastener Metal Roofing System (Metal Shingles)

Example of Concealed Fastener Metal Slate Shingles.

 

Concealed fastener metal shingles interlock with adjacent panels (all 4 sides) for a smooth and clean appearance. These systems are designed to be installed directly to the roof deck. Important to note is that they are not “through fastened” meaning the panels are not penetrated with screws. Interlocking metal roofs cost more than overlapping metal roofs because they have more detailed designs and complex manufacturing.

 

Advantages

  • permanent roofing material
  • energy efficient
  • recycled/recyclable content
  • high speed wind resistant
  • fire resistant
  • hail resistant
  • pest resistant
  • does not support fungus/organic growth
  • less expensive than asphalt shingles over time

 

In addition to having all of the major benefits a metal roof can offer, a concealed fastener metal roofing system has the following extra advantages.

Concealed Fastener Extra Advantages

  • superior wind resistance
  • no need for battens or strapping
  • negligible gap between roof and metal panels
  • no extra screw holes or washers necessary*
  • no maintenance required
  • works well on roofs with low dormer windows
  • diverse and detailed style choices

*In Canada metal roof starter strips, valleys and trims are usually screwed down for extra resistance against heavy snow and ice and wind.

 

Locally Available Materials: galvanized steel, galvalume steel and aluminum.

Locally Available Finishes: pre-painted SMP, PVDF, matte, glossy, crinkle and stone coated (textured).

Locally Available Styles: cedar shake look, slate look and architectural shingle style.

The name standing seam refers to the distinct raised vertical seams that lock one panel to the next. Each panel runs continuously from the roofs eave all the way up to the ridge providing maximum protection from wind, rain, ice and snow. There are 2 main types of standing seam used locally, Mechanical Lock and Snap Lock which refers to the method used to lock one seam to the adjacent panel.

 

Advantages

  • permanent roofing material
  • energy efficient
  • recycled/recyclable content
  • high speed wind resistant
  • fire resistant
  • hail resistant
  • pest resistant
  • does not support fungus/organic growth

  • no gap between roof and metal panels
  • best wind resistance of any roofing product
  • no extra screw holes or washers necessary*
  • no maintenance required
  • works well on roofs with low dormer windows
  • provides the best weatherproofing for low sloped roofs
  • available in unlimited metals, alloys, and pre-painted finishes
  • available in heavier gauges or thickness than other metal roofs

*In Canada metal roof starter strips, valleys and trims are usually screwed down for extra resistance against heavy snow and ice and wind.

 

Locally Available Materials: galvanized steel, galvalume steel, aluminum, zinc and copper.

Locally Available Finishes: pre-painted SMP, PVDF, matte, glossy, crinkle textured and natural unpainted metals.

Locally Available Styles: snap lock and mechanical lock.

 

Standing Seam Metal Roof Cost

Metal SubstrateAverage WarrantyCost/Sqft.
Galvanized Steel50 Years$9.00-$12.00
Galvalume Steel50 Years$9.00-$12.00
Aluminum50 Years and up$12.00-$18.00
Weathering Steel50 Years$16.00-$25.00
Zinc*Up to 100 Years$25.00-$35.00
Copper*Up to 100 Years$22.00-$30.00

*Zinc, Copper and Weathering Steel are considered specialty metals and can come in a wider range of gauge or thickness. Price variance will be more considerable as the price/tonne of raw material is far greater than steel and aluminum. Metal roofing suppliers will need to check prices for these daily rather than list static prices.

Factors That Affect Metal Roof Cost

  • metal roof cost factor pitch
    A "non-walk" roof or steep roof often requires a boom truck for installation.

Outside of the cost of materials there are factors that affect the installed price of the metal roof you decide to go with. You can see in the table below how each factor will affect price and why. If your roof situation warrants 2 or more increase factors, expect to pay on the high-end of the listed prices.

ConditionDescriptionWhy it Affects CostCost Affect
Roof PitchSteep slopes that are not walkableSteep roofs or “non-walk” roofs take longer to install and require special equipment.Increase
Location AccessibilityIs it accessible by car? Is there parking for trailers near the base of roof?Extra travel expenses may be incurred and it may take longer to get materials/equipment up to the roof.Increase
Multiple Intersecting Planes or curvesRoofs that have multiple hips, ridges and valleys that intersectMultiple intersecting planes like combination gable/hip roofs need more time for trims and flashing. More cutting of panels results in more wasted product and slows down installation. Details like Turrets and bell curved roof sections are especially difficult.Increase
Dormer windowsWindows protruding from the roofDormer windows require hand trimming of panels and custom flashingsIncrease
ChimneyMasonry considerationsIf your chimney is brick your roofing installer may suggest cutting into the brickwork for a better sealIncreases
