Question 1
Which of the following is the primary purpose of valley flashing on a roof?
A. To channel water from intersecting roof planes into the gutter system
B. To increase attic ventilation
C. To support the roof decking
D. To improve the roof's appearance
🟢 Correct Answer:
A. To channel water from intersecting roof planes into the gutter system
🔴 RATIONALE:
Valley flashing is installed where two roof slopes meet. It provides a watertight channel that directs runoff to the
gutters, preventing leaks at a vulnerable transition.
Question 2
During an inspection, an electric water heater is found to have a missing bonding jumper between the hot and
cold water pipes. What is the primary concern?
A. Reduced water pressure
B. Increased risk of galvanic corrosion and electrical shock
C. Increased heating time
D. Reduced tank capacity
,🟢 Correct Answer:
B. Increased risk of galvanic corrosion and electrical shock
🔴 RATIONALE:
The bonding jumper maintains electrical continuity between metal pipes, reducing galvanic corrosion and
preventing a possible shock hazard. Its absence is a safety and durability defect.
Question 3
A home inspector observes that an exterior wall outlet has no bubble cover and is not weather-resistant. Which
condition is most likely to occur?
A. Overload of the circuit
B. Voltage drop
C. Reduced breaker life
D. Moisture intrusion and electrical hazard
🟢 Correct Answer:
D. Moisture intrusion and electrical hazard
🔴 RATIONALE:
Outdoor receptacles require weather-resistant and weatherproof covers to prevent moisture from entering the
outlet, which can cause corrosion, ground faults, and shock or fire risk.
,Question 4
What is the minimum required headroom for a residential stairway?
A. 6 feet 4 inches
B. 6 feet 8 inches
C. 7 feet 6 inches
D. 8 feet
🟢 Correct Answer:
B. 6 feet 8 inches
🔴 RATIONALE:
Most residential codes require a minimum headroom of 6 feet 8 inches measured vertically from the stair
nosing to prevent head injuries.
Question 5
Which of the following is the primary function of a plumbing cleanout?
A. To allow access for removing blockages in the drain line
B. To ventilate the drainage system
C. To increase water flow
D. To regulate water pressure
🟢 Correct Answer:
A. To allow access for removing blockages in the drain line
, 🔴 RATIONALE:
Cleanouts are access points in the drainage system that allow a plumber to clear clogs. They are not for venting,
increasing flow, or regulating pressure.
Question 6
During an attic inspection, the inspector sees that bathroom exhaust fans terminate directly into the attic space.
What is the most likely consequence?
A. Improved attic ventilation
B. Reduced humidity in the bathroom
C. Moisture accumulation, mold, and deterioration of roof framing
D. Increased energy efficiency
🟢 Correct Answer:
C. Moisture accumulation, mold, and deterioration of roof framing
🔴 RATIONALE:
Venting a bathroom fan into the attic adds warm, moist air to the attic. This can cause condensation, mold
growth, and wood decay on roof framing.
Question 7
A deck is supported by a ledger board attached to the house without flashing. What is the most likely problem?
A. Excessive deck movement
