Final answer:
Home inspectors are not required to predict the future life expectancy of roof-covering materials as per the InterNACHI Home Inspection Standards of Practice.
Step-by-step explanation:
According to the InterNACHI® Home Inspection Standards of Practice, home inspectors are not required to determine the future life expectancy of roof-covering materials.
The primary responsibility of home inspectors is to perform a visual inspection of the property and identify any existing defects or issues.
Predicting the future lifespan of roofing materials involves a level of speculation that is beyond the scope of a standard home inspection. Home inspectors must operate within the bounds of their standards of practice, which emphasize the current condition of the home's elements rather than prognostication about their future condition.
