Humber/Ontario Real Estate Course 3 Exam Practice

Which type of roofing material is best suited for long-term durability and low maintenance for a sloped roof?

1. A roof made of wood shingles.

2. A roof made of asphalt shingles.

3. A roof made of metal.

4. A roof made of plastic tiles.

5. A roof made of clay tiles.

6. A roof made of composite materials.

The correct answer is: A roof made of metal.

Choosing metal roofing as the best option for long-term durability and low maintenance for a sloped roof is well-founded. Metal roofs are known for their exceptional longevity, often lasting 40 years or more with proper installation and maintenance. They are resistant to many of the common issues that affect other materials, such as decay, warping, and insect damage. Additionally, metal roofs are lightweight, which can reduce structural stress, and they are often designed to shed snow and rain effectively. Another advantage is their low maintenance requirements. Metal roofing typically needs only periodic inspections and cleaning to ensure optimal performance, unlike some other materials that may require regular treatment or replacement due to weathering or wear over time. Furthermore, metal roofs can reflect solar heat, making them energy efficient and helping to reduce cooling costs. While other materials like clay tiles and composite materials also have good durability, they may not have the same low maintenance ease as metal roofing. Clay tiles, for example, are very durable but can be brittle and may require more care during installation and maintenance, particularly in freeze-thaw climates. Similarly, wood shingles can offer a natural aesthetic but generally demand more upkeep to prevent rot and require treatment against pests.
