What is the budget difference between a hip roof and a gable roof on a detached garage in Ottawa?

Hip roofs typically cost $3,000 to $8,000 more than gable roofs on a detached garage in Ottawa, with the exact difference depending on garage size and complexity. A basic 24x24 foot two-car garage with a simple gable roof might cost $8,000 to $12,000 for the complete roof system, while the same garage with a hip roof would run $11,000 to $20,000.

The cost difference stems from several factors that matter particularly in Ottawa's climate. Hip roofs require more complex engineering and additional materials — instead of two triangular end walls (gables), a hip roof slopes on all four sides, requiring more roof trusses, additional ridge and hip boards, and significantly more labour for framing and sheathing. The increased surface area means more shingles, underlayment, and flashing materials. Hip roofs also require more sophisticated truss engineering to handle Ottawa's snow loads, as the load distribution is more complex than a simple gable design.

However, hip roofs offer meaningful advantages in Ottawa's extreme weather conditions. They're more aerodynamic and handle high winds better than gable roofs, which can be important during ice storms and severe weather events. The four-sided slope also sheds snow more evenly, reducing the risk of ice dam formation that can plague gable roofs with their large flat end walls. Hip roofs also provide a more finished appearance and can increase property value, though the premium varies by neighbourhood.

The main drawback beyond cost is reduced storage space — gable roofs create usable triangular storage areas at each end, while hip roofs slope away on all sides, limiting overhead storage options. For Ottawa homeowners planning to use their garage for workshop space or extensive storage, this lost space can be a significant consideration.

When budgeting for either roof style, remember that Ottawa's building code requires engineered roof systems designed for local snow loads, and cutting corners on roof engineering has proven catastrophic during heavy snow years.
