What is the cost difference between a truss roof and a rafter roof on a garage in Bathurst NB?

For a typical two-car garage in Bathurst, engineered trusses cost $2,000-$4,000 less than stick-built rafters when you factor in materials, labour, and the structural advantages trusses provide in NB's heavy snow load environment.

The upfront material cost difference is smaller than many homeowners expect. Engineered roof trusses for a 24x24 garage in Bathurst run approximately $2,500-$4,500 delivered, depending on the truss spacing (typically 24 inches on center), roof pitch, and snow load rating. Bathurst requires trusses engineered for ground snow loads of 3.6-4.8 kPa (75-100 pounds per square foot) due to the city's northern location and proximity to the Chaleur Bay, which can create localized heavy snow conditions.

Stick-built rafters for the same garage require approximately $3,500-$5,500 in dimensional lumber (2x10 or 2x12 rafters, ridge beam, collar ties, ceiling joists), plus significantly more labour. A rafter roof takes an experienced framing crew 2-3 days to cut, fit, and install, while pre-engineered trusses can be set in 4-6 hours with a crane. In Bathurst's construction market, this labour difference translates to $1,500-$2,500 in savings.

The structural advantages of trusses become critical in Bathurst's climate. The city regularly receives 200-300 cm of snowfall annually, and lake-effect snow from the Chaleur Bay can create sudden, heavy accumulations. Engineered trusses are designed specifically for your garage's dimensions and Bathurst's snow load requirements, with the engineering stamp providing assurance that the roof structure will safely carry design loads. Stick-built rafters rely on the framer's experience and standard span tables, which may not account for the specific load combinations your garage will face.

Trusses also provide better ceiling height and storage potential. Most garage trusses use a modified king post or queen post design that leaves the center span relatively clear, allowing for overhead storage between the bottom chords. Stick-built rafters with collar ties create more obstructions and typically provide less usable attic space.

The main advantage of stick-built rafters is flexibility during construction. If you're planning a bonus room above the garage, rafters allow the framing crew to modify the roof structure as needed for dormers, skylights, or stairway openings. Trusses are engineered as complete systems and cannot be cut or modified without compromising their structural integrity. For a simple garage roof without future modifications planned, this flexibility rarely justifies the additional cost.

Bathurst's building season also favors trusses. The city's construction season effectively runs from April through November, with the best roofing weather occurring between May and October. Trusses allow faster roof assembly, getting the structure dried-in before Bathurst's early winter weather arrives. A garage that's framed in September can be under roof and ready for siding within days using trusses, while stick-built rafters might push roofing into October when weather becomes less predictable.

When to consider stick-built rafters: If you're planning a complex roofline with multiple dormers, skylights, or integration with an existing house roof, the flexibility of rafters may justify the additional cost. Also, if your garage site has access limitations that prevent crane delivery of trusses, stick-building may be your only option.

For most garage projects in Bathurst, engineered trusses provide better value, faster installation, engineered snow load capacity, and lower total project cost. The $2,000-$4,000 savings can be invested in other garage features like insulation, upgraded siding, or a concrete floor coating that will provide long-term benefits in NB's demanding climate.
