Aluminum Soffit Cost Per Square Foot in Ottawa

Aluminum Soffit Installation Costs in Ottawa

Aluminum soffit installation in Ottawa typically costs $8 to $16 per square foot installed, including materials and labour. That works out to roughly $12 to $25 per linear foot when you factor in the standard soffit depth of 12 to 24 inches on most Ottawa homes. For a typical bungalow with approximately 200 to 300 square feet of soffit area, expect a total project cost of $1,600 to $4,800. A two-storey home with 300 to 500 square feet of soffit runs $2,400 to $8,000.

The price per square foot varies based on the type of soffit panel. Vented soffit panels, which have perforations that allow airflow into the attic space, are the standard choice for most Ottawa homes and cost $8 to $12 per square foot installed. Proper soffit ventilation is critical in Ottawa's climate because it helps prevent ice dams by keeping the attic cold and stopping heat from melting snow on the roof. The Ontario Building Code requires a minimum of 1 square foot of ventilation for every 300 square feet of attic space when both soffit and ridge vents are used together.

Solid soffit panels are used in areas where ventilation is not needed, such as porch overhangs and covered entries. Solid panels cost slightly less at $7 to $10 per square foot installed because the material is less expensive to manufacture. Most Ottawa installations use a combination of vented and solid panels.

Concealed-fastener aluminum soffit in a smooth or wood-grain finish represents the premium end at $12 to $16 per square foot. These panels create a cleaner look with no visible nail heads and are popular on higher-end homes in neighbourhoods like Westboro, the Glebe, and Riverside South.

Labour accounts for roughly 50 to 60 percent of the installed cost because soffit work requires careful cutting, fitting around corners and obstructions, and working overhead on ladders or scaffolding. Removing old damaged soffit adds $2 to $4 per square foot to the project if the existing material needs to come down first. Fascia board repair, which is often discovered once old soffit is removed, can add another $8 to $15 per linear foot for wood replacement or aluminum wrapping.

Ottawa's extreme temperature swings demand proper installation technique. Aluminum soffit panels must be installed with expansion gaps at joints and fasteners that allow the panel to slide slightly as it expands and contracts. A 12-foot soffit panel can shift by nearly 3 millimetres between a minus-30 winter night and a plus-35 summer afternoon. Panels nailed too tightly will buckle and warp.

If your home is in one of Ottawa's heritage conservation districts — including Centretown, Sandy Hill, or Rockcliffe Park — your soffit materials, colour, and profile may need to conform to heritage guidelines. A heritage permit under Section 42 of the Ontario Heritage Act may be required if the work alters the exterior appearance of a designated property. Contact 3-1-1 to check before proceeding.
