Structure
The home’s “skeleton” should be able to stand up to weather, gravity, and the earth that surrounds it. Structural components include items such as the foundation and the framing.
Exterior
The inspector should look at sidewalks, driveways, steps, windows, doors, siding, trim, and surface drainage. They should also examine any attached porches, decks, and balconies.
Roofing
A good inspector will provide very important information about your roof, including its age, roof draining systems, buckled shingles, and loose gutters and downspouts. They should also inform you of the condition of any skylights and chimneys as well as the potential for pooling water.
Plumbing
They should thoroughly examine the water supply and drainage systems, water heating equipment, and fuel storage systems. Drainage pumps and sump pumps also fall under this category. Poor water pressure, banging pipes, rust spots, or corrosion can indicate larger problems.
Electrical
You should be informed of the condition of service entrance wires, service panels, breakers and fuses, and disconnects. Also take note of the number of outlets in each room.
Heating and air conditioning
The home’s vents, flues, and chimneys should be inspected. The inspector should be able to tell you the water heater’s age, its energy rating, and whether the size is adequate for the house. They should also describe and inspect all the central air and through-wall cooling equipment.
Interiors
Your inspector should take a close look at walls, ceilings and floors; steps, stairways, and railings; countertops and cabinets; and garage systems. These areas can reveal leaks, insect damage, rot, construction defects, and more.
Ventilation/insulation
Inspectors should check for adequate insulation and ventilation in the attic and in unfinished areas such as crawl spaces. Insulation should be appropriate for the climate. Without proper ventilation, excess moisture can lead to mold and water damage.
Fireplaces
They’re charming, but fireplaces can be dangerous if they’re not properly installed. Inspectors should examine the vent and flue, and describe solid fuel-burning appliances.
