Question 1: What is the primary purpose of a home inspector evaluating the foundation?
Answer & Rationale: To identify observable signs of structural distress — such as
cracking, settlement, or moisture intrusion — that could affect the safety and
performance of the structure. Inspectors report visible conditions; they do not
calculate load-bearing capacity or engineer repairs.
Question 2: A diagonal (stair-step) crack in a concrete block foundation wall most likely
indicates what?
Answer & Rationale: Differential settlement. Stair-step cracks that follow the mortar
joints usually mean one part of the foundation is settling at a different rate than
another, often due to uneven soil support or moisture changes beneath the footing.
Question 3: What does 'differential settlement' mean?
Answer & Rationale: Uneven sinking of a foundation where one section drops more
than another, typically caused by variations in soil bearing capacity, moisture content,
or fill material, which produces cracking and out-of-level floors.
Question 4: Why are horizontal cracks in a basement wall considered more serious than
vertical cracks?
Answer & Rationale: Horizontal cracking often signals lateral hydrostatic or soil
pressure pushing against the wall, which can indicate the wall is bowing or failing
structurally, whereas vertical cracks are more commonly due to normal concrete
shrinkage.
Question 5: What is the function of a footing in residential construction?
Answer & Rationale: A footing is the widened base beneath a foundation wall or
column that spreads the structure's weight over a larger area of soil, preventing
excessive settlement.
Question 6: What is 'sistering' in reference to floor joists?
Answer & Rationale: Attaching a new joist alongside a damaged or undersized one
to add strength and restore load capacity without fully removing the original
member.
Question 7: An inspector notices bouncy or springy floor framing. What should be
checked first?
, Answer & Rationale: The size and spacing of the floor joists relative to their span,
along with any signs of undersized framing, excessive notching or drilling, or
moisture damage that could be reducing the joists' effective strength.
Question 8: What is the purpose of a beam or girder in a floor system?
Answer & Rationale: To carry the load of the floor joists above and transfer that load
down to the foundation or support columns, spanning distances too great for joists
alone to bridge.
Question 9: Why is notching or drilling through the middle third of a joist's span a
concern?
Answer & Rationale: That is the zone of highest bending stress in a simply supported
joist; cutting into it there significantly weakens the member and increases risk of
failure, unlike notches near the ends where stress is lower.
Question 10: What visual clue on interior drywall often points to foundation movement?
Answer & Rationale: Diagonal cracks radiating from the corners of doors and
windows, along with doors and windows that stick or no longer close properly, which
suggest the frame has racked out of square.
Roofing Systems
Question 11: What is the standard minimum slope for asphalt shingles to shed water
properly?
Answer & Rationale: Generally 2:12 (with special low-slope application methods) or
4:12 for standard installation, per most shingle manufacturer instructions; below that,
water can back up under the shingles.
Question 12: What is the purpose of roof flashing?
Answer & Rationale: To seal the joints where the roof plane meets another surface
(chimneys, walls, valleys, vent pipes) so that water is directed away from those
transition points rather than seeping into the structure.
Question 13: What does 'granule loss' on asphalt shingles typically indicate?
Answer & Rationale: Aging and weathering of the shingle surface; the protective
mineral granules erode over time from UV exposure and weather, and heavy granule
loss suggests the shingles are nearing the end of their useful life.
Question 14: What is a 'valley' on a roof, and why does it need special attention?
