1. A home inspector observes evidence of moisture intrusion in a
basement wall. Which of the following is the most likely cause?
A. Improper grading away from the foundation
B. Over-insulation of the wall cavity
C. High indoor humidity from cooking
D. Excessive air conditioning use
A. Improper grading away from the foundation
Rationale: Poor exterior grading allows surface water to flow toward
the foundation, leading to moisture intrusion, which is more
significant than internal humidity or insulation issues.
2. When assessing a roof covering, the primary purpose of flashing is to:
A. Enhance roof aesthetics
B. Direct water away from vulnerable roof intersections
C. Reduce attic heat transfer
D. Anchor roofing materials
B. Direct water away from vulnerable roof intersections
Rationale: Flashing is installed at roof penetrations and intersections
to prevent water ingress; it is not primarily decorative or structural
anchoring.
3. In a conventional residential electrical service panel, a double-pole
breaker rated for 240 volts typically protects:
, A. The lighting circuits
B. A single 120-volt branch circuit
C. Large appliances like electric ranges
D. The grounding conductor
C. Large appliances like electric ranges
Rationale: A double-pole breaker spans both hot legs delivering 240
volts, suitable for high-demand appliances, not standard lighting or
grounding conductors.
4. A common sign of a failing galvanized steel water supply pipe is:
A. Blue staining on fixtures
B. Rust particles and reduced water flow
C. Loud water hammer noises
D. Excessively hot water
B. Rust particles and reduced water flow
Rationale: Corrosion inside galvanized pipes leads to rust release and
flow restriction; blue staining suggests copper corrosion, unrelated to
galvanization.
5. The best method to evaluate a bathroom exhaust fan’s performance is
to:
A. Listen for noise level only
B. Check for visible dust buildup
C. Confirm air movement at the exterior exit point
D. Inspect the fan’s color match with ceiling paint
C. Confirm air movement at the exterior exit point
Rationale: Measuring actual airflow at the termination point verifies
fan effectiveness, whereas noise, dust, or aesthetics do not
determine performance.
6. A home inspector notices a chimney with significant outward bowing
of the masonry. This condition is most likely due to:
A. Improper mortar color
B. Foundation settlement
C. Wind exposure
D. High interior temperatures
B. Foundation settlement
, Rationale: Differential settlement can push the chimney off plumb;
weather alone would not deform solid masonry to the same degree.
7. The primary function of weep holes in a brick veneer wall is to:
A. Increase insulation
B. Allow moisture to escape from behind the veneer
C. Provide decorative shadow lines
D. Ventilate interior rooms
B. Allow moisture to escape from behind the veneer
Rationale: Weep holes at the bottom of cavity walls release trapped
moisture, preventing accumulation and damage.
8. When inspecting a furnace heat exchanger, the inspector is most
concerned with:
A. The color of the exterior paint
B. Cracks that could allow combustion gases into living spaces
C. The number of burners present
D. The type of vent termination
B. Cracks that could allow combustion gases into living spaces
Rationale: Cracked heat exchangers compromise safety by
permitting carbon monoxide and other gases into the home.
9. A home built before 1978 is most likely to contain which hazardous
material?
A. Asbestos shingles only
B. Lead-based paint
C. Fiberglass insulation
D. Polyvinyl chloride siding
B. Lead-based paint
Rationale: Homes constructed prior to 1978 often used leaded paint,
posing significant health hazards, whereas PVC siding and fiberglass
are unrelated hazards.
10. Which term describes the upward movement of moisture
through porous building materials?
A. Capillary action
B. Percolation
C. Sublimation
D. Condensation
