Home Inspector Test Top Rated Home Inspector 3 — Questions and Answers
Question 1: During a roof inspection, what does 'flashing' refer to?
- The reflective coating applied to shingles
- Metal strips used to seal roof joints and prevent water intrusion (Correct answer)
- The process of testing for roof leaks with water
- Visible light reflection from wet roofing materials
Correct answer: Metal strips used to seal roof joints and prevent water intrusion
Flashing is metal material installed at roof joints, valleys, and penetrations to direct water away and prevent leaks.
Question 2: A home inspector observes efflorescence on a basement wall. What does this indicate?
- Mold growth requiring biohazard remediation
- Water has been moving through the masonry, depositing mineral salts (Correct answer)
- A harmless decorative pattern in the concrete
- Evidence of a past fire in the basement
Correct answer: Water has been moving through the masonry, depositing mineral salts
Efflorescence is the white powdery deposit left when water carries soluble salts through masonry and evaporates at the surface.
Question 3: What is the minimum recommended clearance between the bottom of a wood structural member and the ground in a crawl space?
- 6 inches
- 18 inches (Correct answer)
- 36 inches
- 12 inches
Correct answer: 18 inches
A minimum of 18 inches of clearance between wood framing and soil in a crawl space is required to prevent moisture damage and pest intrusion.
Question 4: Which roof slope is generally considered the minimum for asphalt shingles to be installed without special underlayment measures?
- 1:12 pitch
- 2:12 pitch
- 3:12 pitch (Correct answer)
- 6:12 pitch
Correct answer: 3:12 pitch
A 3:12 pitch is typically the minimum for standard asphalt shingle installation; lower pitches require low-slope or modified methods.
Question 5: An inspector finds double-tapped breakers in a main electrical panel. Why is this a concern?
- It overloads the neutral bus and trips the main breaker
- Multiple wires on a single breaker terminal can cause arcing and overheating (Correct answer)
- It violates the color-coding requirements for circuits
- Double-tapping is only allowed on 20-amp breakers
Correct answer: Multiple wires on a single breaker terminal can cause arcing and overheating
Most breakers are designed for a single conductor; double-tapping can result in poor connections, arcing, and fire risk.
Question 6: What is the primary purpose of inspecting attic ventilation during a home inspection?
- To verify the attic meets fire egress requirements
- To ensure adequate airflow that prevents moisture buildup and ice dams (Correct answer)
- To confirm the attic insulation is the correct color
- To check for unauthorized living space conversion
Correct answer: To ensure adequate airflow that prevents moisture buildup and ice dams
Proper attic ventilation controls moisture and temperature, preventing condensation, mold, wood rot, and ice dam formation.
Question 7: When should a home inspector recommend air quality testing for radon?
- Only in homes older than 50 years
- In all homes, particularly in geographic areas known for elevated radon levels (Correct answer)
- Only if the basement smells like sulfur
- Only in homes without a basement
Correct answer: In all homes, particularly in geographic areas known for elevated radon levels
Radon is a colorless, odorless gas and the second leading cause of lung cancer; testing is recommended especially in high-risk geographic regions.
