Humber/Ontario Real Estate Course 2 Exam Practice

Which of the following statements is correct about roofing materials and their installation?

1. A standard roof pitch is required by the Ontario Building Code for all shingled, residential roofs in Ontario

2. Attic venting systems help regulate the temperature in the house

3. Flashing is typically used at the juncture between different roofing materials

4. Roof leaks are easily detected because the associated water stains appear directly below the source of the leak

The correct answer is: Attic venting systems help regulate the temperature in the house

Option B is correct because attic venting systems play a crucial role in regulating the temperature in a house. Proper ventilation in the attic helps to maintain a consistent temperature, prevent moisture buildup, and prolong the life of the roofing materials. It also assists in preventing ice dams in the winter and reducing energy costs associated with heating and cooling the house. Therefore, understanding the importance of attic venting systems is essential for ensuring the overall health and longevity of a roof and the house as a whole. Options A, C, and D are incorrect: A. A standard roof pitch is not required by the Ontario Building Code for shingled, residential roofs in Ontario. While pitch requirements may vary based on factors such as roof design and local climate conditions, there is no blanket standard pitch specified by the building code. C. Flashing is typically used at the juncture between roofing materials and roof penetrations (such as chimneys, skylights, or vents) rather than between different roofing materials. Flashing helps to channel water away from these vulnerable areas to prevent leaks. D. Roof leaks are not always easily detected by water stains appearing directly below the source of the leak. Water can travel along roof structures, insulation, or other building materials before manifesting as a visible stain on the ceiling. This means that the location of the water stain may not always correspond directly to the source of the leak.
