A professional home inspection is one of the most important steps in the real estate process. Whether you’re buying, selling, or maintaining a home, understanding what’s included in a home inspection helps you make informed decisions and avoid unexpected repairs.
This guide explains the major systems and components inspected during a standard home inspection and what homeowners can expect.
Exterior & Structural Components
The inspection typically begins with the exterior of the home, where many long-term issues originate.
Inspectors evaluate:
-
Foundation and visible structural elements
-
Exterior walls, siding, stucco, and trim
-
Driveways, walkways, patios, and grading
-
Drainage patterns and slope away from the structure
-
Decks, balconies, porches, and guardrails
Proper drainage and exterior condition help prevent water intrusion, settlement, and structural damage.
Roof System
The roof protects the home from weather and moisture intrusion.
A roof inspection includes:
-
Roof covering materials (shingles, tile, flat roofing)
-
Flashing, penetrations, and roof transitions
-
Gutters and downspouts
-
Visible signs of leaks, wear, or damage
Roof defects are among the most costly issues found during inspections, making this system especially important.
Electrical System
Electrical safety is a major focus of a home inspection.
Inspectors check:
-
Main electrical panel and subpanels
-
Visible wiring and grounding components
-
Outlets, switches, and light fixtures
-
GFCI and AFCI protection where applicable
-
Observable electrical safety hazards
Electrical deficiencies can pose fire and shock risks if not corrected.
Plumbing System
Plumbing inspections help identify leaks, corrosion, and performance concerns.
The inspection includes:
-
Supply and drain piping in visible areas
-
Water heater and safety components
-
Sinks, tubs, showers, toilets, and faucets
-
Water pressure and drainage performance
-
Signs of leaks, moisture damage, or corrosion
Unaddressed plumbing issues can lead to water damage and mold conditions.
Heating & Cooling (HVAC)
Heating and cooling systems are evaluated for condition and basic operation.
Inspectors assess:
-
Heating equipment (furnace, heat pump, etc.)
-
Air conditioning units
-
Thermostat functionality
-
Visible ductwork and airflow
-
Signs of improper installation or wear
HVAC systems affect comfort, energy efficiency, and indoor air quality.
Interior Components
Interior areas are evaluated for safety, operation, and visible condition.
Inspectors examine:
-
Walls, ceilings, and floors
-
Doors and windows for proper operation
-
Stairs, handrails, and guardrails
-
Visible cracks, stains, or moisture intrusion
-
General wear and tear consistent with age and use
Interior findings often indicate maintenance history or settlement movement.
Attic, Insulation & Ventilation
Attics and crawlspaces provide insight into moisture and energy performance.
The inspection includes:
-
Attic access and visible framing
-
Insulation levels and installation
-
Attic, bathroom, and kitchen ventilation
-
Crawlspace conditions, if accessible
Poor insulation or ventilation can lead to heat loss, condensation, and structural deterioration.
Fire & Safety Features
Safety components are reviewed during the inspection.
These typically include:
-
Smoke detectors
-
Carbon monoxide detectors
-
Visible fire hazards
-
Basic safety concerns related to egress and stairs
