What is the primary function of drip edge flashing installed along the eaves?
Answer: To direct water off the roof edge into the gutter and away from the fascia
Drip edge flashing guides water off the roof edge into the gutter and protects the fascia board and roof deck from water infiltration.
Which roof covering material has the longest typical service life under normal conditions?
Answer: Slate
Natural slate roofing can last 75–150 years or more, significantly outlasting other common residential roofing materials.
An inspector notices that roof sheathing panels have no H-clips installed between rafters. What concern does this raise?
Answer: Potential for panel edge sag between rafters without support
H-clips (panel clips) support sheathing panel edges between rafters to prevent sagging and maintain a flat, even deck surface.
What does the term 'exposure' refer to when describing asphalt shingles?
Answer: The portion of the shingle visible after installation
Exposure is the portion of a shingle visible and exposed to weather after the overlapping course above is installed.
During an inspection, a home inspector observes open valleys on an older roof. What is the recommended inspection finding?
Answer: Open metal valleys are an acceptable roofing method that should be checked for rust and integrity
Open metal valleys are an accepted and traditional roofing method; inspectors should assess them for corrosion, proper width, and damage rather than condemning the design.
Which condition in an attic most directly contributes to premature deterioration of roof shingles from below?
Answer: Inadequate attic ventilation causing excessive heat buildup
Inadequate ventilation traps heat in the attic, which bakes shingles from below, accelerating thermal cracking and reducing shingle lifespan.
What defect is indicated when roof shingles show a pattern of missing granules in a circular or dimpled pattern?
Answer: Hail impact damage
Circular or dimpled granule loss patterns are characteristic of hail impact damage, which bruises the shingle mat beneath the granule layer.
