Home Inspector Test Home Online Inspector 5 — Questions and Answers
Question 1: An online inspector reviewing thermal imaging footage provided by the homeowner sees a cool spot on a ceiling below a bathroom. What is the most likely cause?
- Water leak from the bathroom above causing moisture in the ceiling assembly (Correct answer)
- A cold air duct above the ceiling
- Normal variation in drywall temperature
- Improper paint application on the ceiling
Correct answer: Water leak from the bathroom above causing moisture in the ceiling assembly
Cool spots on thermal images below a bathroom typically indicate moisture intrusion from a plumbing leak, which can lead to mold and structural damage.
Question 2: Which of the following is an inspector's ethical obligation when a client asks them to overlook a defect to help close a real estate deal?
- Refuse and document all defects accurately regardless of pressure from any party (Correct answer)
- Comply if the defect is minor and the client accepts the risk verbally
- Skip the item from the report but mention it verbally
- Transfer the file to another inspector without explanation
Correct answer: Refuse and document all defects accurately regardless of pressure from any party
Home inspectors have a professional and ethical duty to report all observed defects impartially, regardless of pressure from clients, agents, or sellers.
Question 3: What does the term 'material defect' mean in the context of a home inspection report?
- A condition that has a significant adverse impact on the value of the property or that poses an unreasonable risk to people (Correct answer)
- Any defect that requires a building material to be replaced
- A defect visible only with specialized equipment
- A defect that costs more than $500 to repair
Correct answer: A condition that has a significant adverse impact on the value of the property or that poses an unreasonable risk to people
A material defect is defined by its impact on safety, habitability, or property value — not simply by repair cost or visibility.
Question 4: During a virtual inspection, an inspector observes that a gas water heater is installed in a bedroom closet without combustion air provisions. What is the primary concern?
- Lack of combustion air can cause carbon monoxide production and backdrafting into living areas (Correct answer)
- The closet location only affects the water heater's efficiency rating
- Gas appliances are never permitted in bedroom closets regardless of venting
- The concern is only aesthetic — the closet door must remain open
Correct answer: Lack of combustion air can cause carbon monoxide production and backdrafting into living areas
Combustion appliances require adequate air supply; without it, incomplete combustion produces carbon monoxide, and negative pressure can pull flue gases back into the home.
Question 5: A homeowner conducting a self-guided virtual inspection shows the inspector a GFCI outlet in the kitchen but does not test it. What should the inspector instruct the homeowner to do?
- Press the TEST button to trip the outlet, verify it loses power, then press RESET to restore it (Correct answer)
- Simply verify the GFCI outlet is present and move on
- Check if the outlet is within 6 inches of the sink
- Replace the outlet immediately since it was not tested
Correct answer: Press the TEST button to trip the outlet, verify it loses power, then press RESET to restore it
GFCI outlets must be functionally tested — visual presence alone does not confirm the device will trip when it detects a ground fault.
Question 6: What ventilation component is most critical to inspect in a crawl space during a remote video walkthrough to prevent moisture problems?
- Foundation vents to ensure they are open, unobstructed, and properly spaced (Correct answer)
- The color of the vapor barrier
- Exposed soil depth below the floor joists
- Presence of insulation on the floor above
Correct answer: Foundation vents to ensure they are open, unobstructed, and properly spaced
Foundation vents provide cross-ventilation that removes moisture-laden air from the crawl space, preventing condensation, wood rot, and mold growth.
Question 7: Which condition on a steep-slope roof is considered a safety and performance defect requiring immediate attention when visible during a remote aerial inspection?
- Missing or lifted flashing at a chimney or roof penetration (Correct answer)
- Presence of moss on a north-facing slope
- Slightly varied shingle color between production runs
- Minor granule loss on shingles older than 15 years
Correct answer: Missing or lifted flashing at a chimney or roof penetration
Missing or lifted flashing at penetrations creates direct water entry paths that can rapidly damage roof sheathing, rafters, and interior ceilings.
