According to the guidelines set by the National Association of Certified Home Inspectors, a home inspection should cover the house's structural elements; an evaluation of the home's exterior, the roof and attic; and the home's plumbing. The home inspector should also check the house's systems and its components, electrical components, appliances and the garage.
A check of the home's structural elements includes inspecting the walls, ceilings, floors, roof and foundation for structural issues. An evaluation of the home's exterior includes all objects and structures on the property located outside the home. This includes the doors, windows, fascia surrounding the roof's edge, trim and lights. Wall coverings, drainage, driveways, sidewalks, landscaping and exterior receptacles are also inspected. The home's roof and attic are also checked for proper ventilation, and the home's roof type is listed. There is also an inspection of the gutters and flashing; however, their reported condition is not guaranteed, and no roof certification is given.
The plumbing is examined to determine the types of pipe materials used and their condition; a sewer inspection is not included. The house's water heater, furnace, air conditioning and ductwork are also investigated. The inspector also looks at the sprinklers, fireplace and chimney. All electrical components, such as wiring, circuit breakers, exhaust fans and all light fixtures, are checked to ensure they are in working order.
