Most Common Home Inspection Call-Outs: What Inspectors Look For

Whether you're buying, selling, or maintaining a home, a home inspection is a critical step in understanding the true condition of a property. While every home is unique, certain issues come up again and again in inspection reports.

Knowing the most common home inspection call-outs can help homeowners proactively address issues—and help buyers make informed decisions.

1. Roofing Issues

Your roof protects your home from the elements, so it’s no surprise it's one of the most frequently flagged areas.

• Missing, curling, or damaged shingles

• Improper flashing or sealing around vents and chimneys

• Signs of leaks or water intrusion in the attic
  Pro Tip: Regular roof maintenance can extend the life of your roof and avoid costly repairs during a sale.

2. Electrical Problems

Electrical safety is a top priority for inspectors. Some of the most common electrical call-outs include:

• Outdated wiring (e.g., knob-and-tube or aluminum wiring)

• Double-tapped breakers in the electrical panel

• Missing GFCI outlets in kitchens, bathrooms, and exterior locations

• Exposed or unsafe wiring
  Call-Out Severity: Electrical issues can be safety hazards and are often deal-breakers for buyers.

3. Plumbing Concerns

Plumbing defects can lead to water damage, mold, and high utility bills.

• Leaking faucets, pipes, or water heaters

• Inadequate water pressure

• Improper drainage or slope

• Polybutylene piping (a known defective material in older homes)
  Pro Tip: Have a licensed plumber assess and repair known issues before listing your home.

4. HVAC System Deficiencies

Your heating and cooling system directly affects comfort and energy costs.

• Dirty or aging systems

• Missing or dirty air filters

• Improper venting or ductwork leaks

• Units not cooling or heating efficiently
  Recommendation: Annual HVAC service can improve performance and extend system lifespan.

5. Moisture and Drainage Problems

Water is one of the most destructive forces to a home. Inspectors often report:

• Foundation cracks or signs of settlement

• Grading issues causing water to pool near the home

• Water stains, mold, or mildew in basements or crawl spaces
  Red Flag: Unaddressed moisture issues can lead to structural damage and mold growth.

6. Structural and Foundation Concerns

Inspectors are trained to spot signs of:

• Uneven floors or wall cracks

• Doors and windows that stick or don’t close properly

• Sagging or bowing walls or ceilings
  While not always major, these symptoms can indicate underlying foundation problems.

7. Exterior and Siding Damage

The condition of the exterior affects both curb appeal and weather resistance.

• Cracked, rotting, or damaged siding

• Gaps around windows or doors

• Inadequate caulking or sealing

• Peeling paint, especially in older homes with lead concerns

8. Attic and Insulation Deficiencies

Energy efficiency and moisture control often hinge on your attic's condition.

• Insufficient insulation or poor ventilation

• Evidence of pest infestations

• Signs of roof leaks or water stains
  Call-Out Tip: Improving attic insulation can enhance comfort and reduce energy bills.

Why These Call-Outs Matter

These issues often show up in inspection reports because they impact:

• Safety

• Structural integrity

• Energy efficiency

• Overall livability

Understanding these red flags in advance helps homeowners fix problems before they become costly or delay a sale.
