NHIE Exterior Evaluation 2 — Questions and Answers
Question 1: When inspecting exterior wall cladding, which condition is MOST indicative of a moisture intrusion problem behind vinyl siding?
- Buckling or warping of the siding panels (Correct answer)
- Slight color variation between panels
- Small gaps at panel overlaps
- Nail heads visible at seams
Correct answer: Buckling or warping of the siding panels
Buckling or warping of vinyl siding panels typically indicates moisture accumulation or swelling of the substrate behind the siding.
Question 2: A home inspector observes that the bottom course of wood siding is within 2 inches of the soil grade. What is the PRIMARY concern?
- Moisture and pest damage to the siding and framing (Correct answer)
- Reduced curb appeal of the home
- Violation of setback requirements
- Poor drainage from the roof system
Correct answer: Moisture and pest damage to the siding and framing
Wood siding close to soil grade is highly susceptible to moisture absorption and wood-destroying organism infestation.
Question 3: When evaluating a deck, what is the MINIMUM recommended post-to-beam connection requirement that an inspector should look for?
- Posts should bear on beams with approved hardware, not be notched beyond half their width (Correct answer)
- Posts must be at least 6x6 lumber regardless of span
- Posts should be embedded directly in concrete footings
- Beam-to-post connections require no hardware if toe-nailed
Correct answer: Posts should bear on beams with approved hardware, not be notched beyond half their width
Proper post-to-beam connections using approved metal hardware prevent separation and are a critical structural safety element on decks.
Question 4: Which of the following is the MOST significant concern when inspecting a chimney that has no cricket or saddle?
- Water can pond behind the chimney and infiltrate the roof assembly (Correct answer)
- The chimney cap may be improperly sized
- Flue gases may not draft properly
- Mortar joints will deteriorate faster than normal
Correct answer: Water can pond behind the chimney and infiltrate the roof assembly
Without a cricket or saddle behind a wide chimney, water ponds and can penetrate the flashing, leading to serious roof and structural damage.
Question 5: During an exterior inspection, a home inspector notices that window sills are sloped toward the house rather than away from it. What should the inspector report?
- A deficiency that can direct water toward the window frame and wall cavity (Correct answer)
- A cosmetic issue requiring no further action
- A code violation requiring immediate correction
- A sign that the windows were improperly manufactured
Correct answer: A deficiency that can direct water toward the window frame and wall cavity
Window sills sloped toward the house allow water to drain against the frame rather than away, increasing risk of moisture intrusion into the wall.
Question 6: What does spalling on a brick exterior wall MOST commonly indicate?
- Water has penetrated the brick, frozen, and caused the face to break away (Correct answer)
- The brick was improperly fired during manufacturing
- Mortar joints were installed too wide
- The wall has inadequate foundation support
Correct answer: Water has penetrated the brick, frozen, and caused the face to break away
Spalling occurs when moisture inside brick freezes and expands, fracturing the outer face off — a sign of ongoing moisture infiltration.
Question 7: When inspecting a garage door, which condition represents a SAFETY hazard that must be reported?
- Auto-reverse mechanism fails to reverse when obstructed by a 2x4 laid flat (Correct answer)
- The door has a single-panel design rather than sectional panels
- Weatherstripping at the bottom is partially detached
- The garage door opener light bulb is burned out
Correct answer: Auto-reverse mechanism fails to reverse when obstructed by a 2x4 laid flat
A non-functioning auto-reverse mechanism on a garage door is a life-safety defect that can cause serious injury or death.
