Final answer:
The correct answer to the question would be (d) a and b. Roof inspections require inspecting the roof surface and identifying the roof covering material, while reporting on remaining life expectancy is not always necessary. The answer to the student's question is thus (d) a and b.
Step-by-step explanation:
Roof inspections are a crucial part of maintaining the integrity of a building's structure. When conducting a roof inspection, certain key tasks must always be performed to ensure a thorough evaluation. These tasks are:
- Inspecting the roof from the roof surface: This allows the inspector to closely examine the condition of the roof material, note any signs of damage or wear, such as missing shingles, punctures, or cracks, and to check for proper flashing and sealing around roof penetrations.
- Identifying the roof covering material: Knowing the type of material used is important for assessing the condition of the roof, as different materials have different lifespans and vulnerability to elements. Common materials include asphalt shingles, metal, tile, and rubber membranes, each with specific inspection criteria.
However, reporting on the remaining life expectancy of the roofing material is not always required, as it can be highly subjective and based on many variables that are hard to quantify during a standard inspection. It is best practice to report on the current condition rather than predict future longevity.
