When inspecting a chimney, a home inspector notices that the mortar crown (chimney cap) has cracks running from the flue liner to the edge. What should the report state?
Answer: The crown should be sealed or replaced to prevent water penetration and spalling
Cracks in the chimney crown allow water to enter the masonry assembly, causing freeze-thaw spalling that can ultimately compromise the structural integrity of the chimney.
What does 'ponding water' on a flat or low-slope roof indicate to a home inspector?
Answer: Inadequate drainage or structural deflection requiring further evaluation
Ponding water (standing water remaining more than 48 hours after rain) on a flat roof indicates drainage deficiencies or structural sagging that accelerate membrane deterioration.
A home inspector observes that roof ventilation is provided only by soffit vents with no ridge or upper vents. What is the primary concern?
Answer: Without high exhaust vents, air cannot circulate through the attic effectively
Effective attic ventilation requires both low intake (soffit) vents and high exhaust (ridge or gable) vents; without the high exhaust point, air cannot rise and exit the attic.
Which of the following best describes 'blistering' observed on asphalt shingles during a roof inspection?
Answer: Moisture or volatile compounds trapped beneath the shingle surface causing bubbles
Blisters form when moisture or residual solvents vaporize and push up through the shingle mat, creating raised bubbles that rupture and expose the asphalt to accelerated weathering.
During a home inspection, the inspector notes that the gutter system has no downspout extensions and downspouts terminate at grade directly against the foundation. What is the primary concern?
Answer: Concentrated water discharge that can cause basement or crawlspace water intrusion
Downspouts discharging at the foundation concentrate roof runoff at the most vulnerable point, overwhelming foundation waterproofing and increasing hydrostatic pressure against basement walls.
A home inspector observes that the pipe boot flashings around plumbing vents on a composition shingle roof are cracked and brittle. What material failure is occurring?
Answer: UV and ozone degradation of the neoprene or EPDM rubber collar
The rubber boot collar surrounding the pipe is typically made of neoprene or EPDM, which deteriorates from UV radiation and ozone exposure, eventually cracking and allowing water to enter around the pipe.
