Any inspection of the attic and insulation is inherently tied to other systems, such as the roof framing, the chimney, and the electrical system. The inspector should enter the attic space only if it is safe to do so. According to the Standards of Practice, the home inspector shall inspect insulation in unfinished spaces, including attics, crawlspace, and foundation areas; ventilation of unfinished spaces, including attics, crawlspaces, and foundation areas; and mechanical exhaust systems in the kitchen, bathrooms, and laundry area.
