When inspecting chimney flashing, which defect is most likely to result in water damage to the home interior?
Answer: Gaps, improper overlap, or failed sealant at the chimney-to-roof interface
Gaps or failed seals at the chimney-roof interface allow water to penetrate directly into the attic and wall cavities, causing significant structural damage.
White crystalline staining observed on the exterior brick of a chimney is called efflorescence. What does it indicate?
Answer: Moisture is moving through the masonry and depositing salts on the surface
Efflorescence occurs when water carries dissolved salts through masonry and deposits them on the surface as it evaporates, indicating chronic moisture infiltration.
What is the correct function of a chimney cap, and what problem does its absence cause?
Answer: It prevents water, debris, and animals from entering the flue; without it these cause blockages and water damage
Chimney caps keep rain, snow, leaves, and animals out of the flue, preventing water damage to the liner and avoiding dangerous blockages from nesting materials.
Spalling bricks observed on a chimney exterior during a home inspection most commonly indicate what condition?
Answer: Chronic moisture intrusion causing freeze-thaw deterioration inside the brick
Spalling occurs when water absorbed into porous brick freezes, expands, and breaks away the brick face, indicating a long-standing moisture problem.
What is the purpose of a chimney cricket (saddle) installed behind a chimney wider than 30 inches?
Answer: To divert roof runoff around the chimney base and prevent water pooling
A cricket is a peaked waterproofing structure behind a wide chimney that directs roof runoff to either side, preventing water accumulation at the chimney base that leads to leaks.
When inspecting a factory-built prefabricated fireplace, what is the most critical defect a home inspector looks for?
Answer: Missing clearances, damaged firebox panels, or unapproved modifications to the unit
Prefabricated fireplaces must maintain manufacturer-specified clearances and use approved components; damaged refractory panels or field modifications create serious fire hazards.
What does a home inspector verify about the non-combustible hearth extension in front of a fireplace opening?
Answer: That the hearth extends at least 16 inches in front of and 8 inches to each side of the firebox opening
Hearth extensions must be non-combustible and extend a minimum of 16 inches forward and 8 inches laterally from the firebox opening to contain sparks and embers.
