Ontario Building Code Practice Exam

Question: 1 / 400

What is the minimum slope required for a roof in a residential building with asphalt shingles?

2/12

3/12

Typically, the minimum slope required for a residential roof with asphalt shingles is between 2/12 and 4/12. This is because asphalt shingles are not as durable and water-resistant as other roofing materials, so a steeper slope is needed to prevent water from pooling and causing damage. Option A is too low of a slope, making it more prone to water damage. Option C is also a bit too low and may still be at risk of water pooling. Option D is slightly higher than the recommended minimum, but may be a good choice for areas with heavy rainfall or snow. Option B strikes a balance between providing enough slope for drainage and not being too steep for easy installation and maintenance.
