Things That Fail a Home Inspection | Halcomb Property Inspection
The most common things that fail a home inspection are roof damage, foundation problems, faulty electrical systems, plumbing failures, HVAC issues, water intrusion, termite damage, and mold. These are the findings that show up most often in inspection reports and the ones most likely to affect your negotiation, your financing, or your decision to walk away. In Arizona, the desert climate adds region-specific risks like UV-related roof wear, stucco moisture intrusion, and aggressive termite activity that buyers in other states simply do not encounter.
At Halcomb Property Inspections, we have spent over 20 years finding exactly these issues across thousands of homes in Phoenix, Chandler, Scottsdale, Mesa, and the greater Maricopa County area. Our InterNACHI-certified inspectors use thermal imaging technology and deliver same-day reports so you have the information you need before the deal closes. We work for you, not the agent or the seller, and our satisfaction guarantee backs every report we deliver.
Key Takeaways
Roof, foundation, electrical, plumbing, and HVAC are the most common and most serious findings.
Arizona adds termites, UV damage, and stucco issues on top of the standard list.
Inspections don't pass or fail a home. They document its condition so you can decide what to do next.
Most findings are negotiable. Deal-breakers are issues that are safety-critical or required by lenders to be fixed before closing.
What Fails a Home Inspection? The Most Common Findings
No home is perfect. Inspectors find something in virtually every property. The key is knowing which common home inspection findings are routine maintenance and which are home inspection issues that are deal breakers.
1. Roof Damage
The roof is one of the first things inspectors assess and one of the most frequently flagged. Home inspection red flags on the roof include missing or cracked tiles, deteriorating flashing, sagging areas, and water staining on attic decking. In Arizona, flat roofs are common and get specific attention for ponding water and membrane wear. Years of UV exposure accelerate deterioration faster here than in most other states.
2. Foundation and Structural Issues
Foundation problems are serious and rarely cheap to fix. Inspectors look for cracks wider than 1/8 inch, bowing walls, uneven floors, and misaligned doors and windows. Arizona's expansive soils shift with moisture changes, making foundation movement more common here than in many other markets. When structural concerns are flagged, a licensed structural engineer evaluation is the expected next step.
3. Electrical System Problems
Electrical issues are among the most common things that fail a home inspection and carry real safety implications. Outdated Federal Pacific and Zinsco panels have documented histories of failure and fire risk. Inspectors also flag overloaded circuits, missing GFCI outlets, exposed wiring, and reversed polarity. According to the U.S. Consumer Product Safety Commission, electrical failures cause tens of thousands of home fires in the United States every year.
4. Plumbing Failures
Active leaks, polybutylene or galvanized steel piping, low water pressure, and water heaters at or past their service life are all common plumbing findings. Galvanized steel pipes corrode internally over time, restricting flow and eventually failing. In older Phoenix-area homes this comes up often and represents real negotiating leverage.
5. HVAC System Issues
In Arizona, HVAC is not a secondary concern. Summer temperatures regularly exceed 110 degrees and a failing unit is a genuine health risk. Inspectors check system age, airflow from all registers, refrigerant connections, visible ductwork, and thermostat function. A cracked heat exchanger in a gas furnace is one of the most serious findings possible, as it can allow carbon monoxide into the living space. The U.S. Environmental Protection Agency classifies carbon monoxide as a critical indoor air quality hazard.
6. Water Intrusion and Moisture Damage
Water damage is one of the most impactful home inspection issues that are deal breakers because it rarely stays contained. Inspectors look for ceiling stains, bubbling paint, soft flooring near bathrooms and kitchens, and stucco cracks at window and door frames where monsoon water enters. Left unaddressed, moisture leads to mold, structural damage, and significantly higher repair costs down the line.
7. Termite and Pest Damage
Arizona is one of the highest-risk states for subterranean termite activity. Inspectors look for mud tubes, wood damage, and evidence of prior treatment. According to the U.S. Department of Housing and Urban Development, FHA and VA loans require a Wood Destroying Insect Inspection Report (WDIIR) before closing. A separate termite inspection is strongly recommended for any Arizona home purchase.
8. Mold and Safety Hazards
Visible mold in attics, under sinks, or in bathrooms signals moisture intrusion, either current or past. The U.S. Environmental Protection Agency notes mold exposure can cause respiratory issues, particularly in sensitive individuals. Beyond mold, inspectors also flag missing handrails, non-functional smoke or CO detectors, garage door safety failures, and unpermitted additions.
Home Inspection Issues That Are Deal Breakers: When to Walk Away
Most findings are negotiable. But some cross into deal-breaker territory. Genuine deal-breakers typically involve a safety risk that cannot be remediated, repair costs disproportionate to the home's value, lender requirements the seller refuses to meet, or multiple major systems failing at once.
Remember: a home inspection produces a report, not a verdict. How you use that report whether you negotiate repairs, ask for a credit, or walk away is entirely your call. The inspection just gives you the information to make that decision with confidence.
What Sellers Can Do Before the Inspection
A pre-listing inspection is the single best thing a seller can do to avoid surprises. It gives you time to address issues proactively, price the home accurately, and present buyers with a transparent picture of the property. Small fixes upfront, like caulking windows, servicing the HVAC, and addressing termite evidence with documentation, prevent much larger concessions during contract negotiations.

Frequently Asked Questions
1. What fails a home inspection most often?
Roof damage, electrical issues, plumbing failures, HVAC problems, water intrusion, foundation concerns, and termite damage. In Arizona, termite activity and UV-related roof and stucco wear are especially common.
2. Are home inspection issues always deal breakers?
No. Most findings are negotiable. Buyers can request repairs, ask for a closing credit, or negotiate a price reduction. True deal-breakers are findings that are safety-critical, required by lenders to be fixed, or financially significant relative to the home's value.
3. What are the biggest home inspection red flags?
Foundation cracks, active water intrusion or mold, outdated electrical panels like Federal Pacific or Zinsco, cracked heat exchangers in HVAC systems, and active termite activity. These either pose safety risks or carry repair costs large enough to affect the transaction.
4. Can a seller refuse to fix things that fail a home inspection?
Yes. Sellers are not legally required to fix every finding. But buyers can use the inspection contingency to negotiate repairs, request credits, or walk away if the seller refuses to address significant issues.
5. What home inspection findings do lenders care about most?
Safety and habitability issues. Roof damage affecting weather-tightness, active water intrusion, electrical hazards, structural concerns, and pest damage. FHA and VA loans in Arizona typically require a WDIIR termite report before closing.
6. Is mold always a deal breaker?
No. Small surface mold in a poorly ventilated bathroom is manageable. Widespread mold in attics or walls from long-term moisture intrusion is more serious and warrants a dedicated mold inspection before proceeding.
7. Do new construction homes have things that fail a home inspection?
Yes. New Arizona builds are not automatically problem-free. Construction defects, improper grading, and installation errors show up regularly. Never assume a brand-new home is problem-free.
8. Can I negotiate after a home inspection?
Yes, and you should. The report is one of your strongest negotiating tools. Request repairs, ask for a closing credit, or negotiate a price reduction based on documented findings. Buyers who attend the inspection are in the best position to do this effectively.
