Systems Check
A professional home inspection is a vital step in protecting your investment, offering a deep dive into the "health" of a property. While a home may look beautiful on the surface, an inspector acts as a detective, looking for the subtle clues that tell the real story of the building's condition.
Here is an expanded look at the core elements of a professional home inspection.
1. Exterior
The home inspector conducts a comprehensive evaluation of the property's exterior, focusing on the protective shell and structural transitions of the building. This includes a detailed inspection of exterior wall coverings, flashing, trim, and all entry doors, alongside attached features like decks, balconies, and porches.
From ground level, they assess the eaves, soffits, and fascias, while also ensuring the primary garage and its mechanical doors are in working order. The scope extends to the immediate surroundings, covering walkways, driveways, and drainage patterns that could potentially threaten the home’s integrity. While the inspector provides a formal description of the wall materials and the specific methods used for their evaluation, they are not required to inspect seasonal accessories, fences, outbuildings, or complex geological and erosion control systems.
2. Roof System Inspection Overview
The home inspector performs a targeted evaluation of the roof’s structural integrity and its ability to shed water effectively. This process involves inspecting all readily accessible roof coverings, drainage systems, and flashings, as well as critical penetration points like skylights, chimneys, and vents.
The inspector is required to formally describe the roofing materials and clearly state the methods used for the evaluation—whether they inspected from the roof edge, a ladder, or ground level. However, the scope is strictly functional; the inspector is not responsible for non-roofing accessories such as satellite dishes or antennae, nor are they required to inspect the internal flues of chimneys or other items unrelated to the primary roof system.
3. Structural Systems Inspection Overview
The home inspector examines the "bones" of the property to identify visible issues with the house's skeleton. This includes a thorough inspection of the visible foundation and framing components. If the inspector suspects rot or decay, they may perform probing on a sample of materials, provided it doesn't damage finished surfaces.
The final report provides a detailed description of the foundation, floors, walls, ceilings, and roof structures, while also documenting any areas where access was limited. It is important to note that the inspector identifies the current condition and the methods used to access crawl spaces or attics; however, they do not provide engineering services or offer formal opinions on the overall structural adequacy or load-bearing capacity of the building.
4. Plumbing Systems
The inspector evaluates the home’s interior water "ecosystem," including the supply lines, waste pipes, and all functional fixtures and faucets. This review encompasses water heating equipment (including flues and vents), fuel storage, and sump pumps. You will receive a description of the piping materials used and the specific locations of main water and fuel shut-off valves.
The inspector is not required to test washing machine connections, private wells, or septic systems, nor will they operate safety valves or determine water quality.
5. Electrical Systems
This evaluation tracks power from the service drop and entrance conductors through to the main panels and sub-panels. The inspector checks the grounding, overcurrent protection (breakers/fuses), and a representative number of outlets and light switches, with a specific focus on GFCI and AFCI safety breakers.
The report will identify the amperage and voltage rating, the location of disconnects, and the presence (or absence) of critical safety devices like smoke and carbon monoxide detectors. Low-voltage systems (like doorbells or security) and telecommunications wiring are outside the scope of this inspection.
6. Interior & Safety
The interior inspection focuses on the structural "skin" and safety of the living space, including walls, floors, ceilings, and stairways. The inspector checks a representative number of doors and windows, along with installed cabinets and countertops. A critical safety check is performed on the firewall separating the garage from the house.
While the inspector reports on missing handrails or other physical hazards, they do not evaluate cosmetic finishes like paint, wallpaper, or carpeting, nor do they test household appliances or central vacuum systems.
7. Heating and Cooling
The inspector assesses the home’s climate control and combustion systems, looking at heating and cooling equipment, fuel distribution, and chimneys. For fireplaces, they inspect visible components and vent systems to ensure they are properly installed.
The report describes the energy sources and venting methods used. However, the inspector is not required to perform "invasive" checks like inspecting the interior of a heat exchanger, checking air quality, or lighting a fire to test a fireplace's draft.
8. Insulation & Ventilation
This section focuses on the home’s ability to "breathe" and retain temperature. The inspector examines insulation and vapor retarders in unfinished spaces (like attics and crawlspaces) and ensures there is adequate ventilation in high-moisture areas like kitchens, bathrooms, and laundries.
The report will specify the type of insulation present and flag any areas where it is missing. To keep the process non-destructive, the inspector will not disturb insulation or move vapor barriers, nor will they provide an official "adequacy" rating for the home’s thermal performance.
