10 Red Flags Your Home Inspector Might Miss (and How to Spot Them)

Introduction

Buying a home is likely the biggest investment you'll ever make. That's why a thorough home inspection is absolutely crucial before you sign on the dotted line. A skilled home inspector acts as your advocate, identifying potential problems that could cost you thousands of dollars down the road. However, even the most experienced home inspectors can sometimes miss things. Some issues are hidden, others require specialized expertise, and sometimes, time constraints simply prevent a truly exhaustive assessment. This article highlights 10 red flags that your home inspector might miss and, more importantly, provides you with actionable tips on how to spot them yourself, ensuring you're making a truly informed decision about your future home. Remember, a second look could save you a fortune and a lot of headaches.

Here are 10 areas where issues can be overlooked during a standard home inspection:

1. Roofing Issues Beyond Obvious Damage: A home inspection will usually cover the obvious signs of roof damage – missing shingles, sagging, or visible leaks. However, subtle problems like granule loss (indicating aging), improper flashing, or issues with underlayment can be easily missed.

   • How to Spot It: Check for excessive granules in your gutters. If possible, get a closer look at the flashing around chimneys, vents, and skylights. Also, inquire about the age of the roof and compare it to the expected lifespan of the roofing material. A drone inspection can often reveal more detailed information without physically climbing on the roof.

2. HVAC System Inefficiencies and Maintenance: While a home inspection will check if the HVAC system turns on and blows hot or cold air, it typically won't delve into the system's efficiency, ductwork leaks, or the condition of internal components like the evaporator coil.

   • How to Spot It: Ask about the system's service history and request records. Look for signs of ductwork leaks – unusually high energy bills, dusty rooms, or temperature inconsistencies. Consider a separate HVAC inspection by a specialist for a more in-depth assessment.

3. Electrical Issues Beyond Basic Functionality: A home inspection covers basic electrical safety, like proper grounding and functioning outlets. But hidden dangers like overloaded circuits, outdated wiring (e.g., aluminum wiring), or improper DIY electrical work can be overlooked.

   • How to Spot It: Check for flickering lights, frequently tripping breakers, or warm outlets. Look at the electrical panel for any signs of amateur wiring or corrosion. Consider having a licensed electrician perform a comprehensive electrical inspection.

4. Plumbing Leaks Behind Walls and Under Slabs: Visible plumbing leaks are usually caught during a home inspection. However, slow, concealed leaks can cause significant damage over time without being immediately apparent.

   • How to Spot It: Check for water stains on ceilings, walls, and floors. Listen for the sound of running water when no fixtures are in use. Look for signs of mold or mildew, which can indicate hidden leaks. Invest in a thermal camera to detect temperature differences behind walls, potentially revealing leaks.

5. Foundation Cracks and Structural Issues: A home inspection will identify obvious foundation cracks or signs of settling. But hairline cracks, inadequate drainage around the foundation, or hidden structural problems might be missed.

   • How to Spot It: Carefully inspect the foundation for cracks, especially near corners and openings. Check the grading around the house to ensure water drains away from the foundation. Look for doors and windows that stick, which can indicate structural movement. A structural engineer can provide a more detailed assessment of the foundation's integrity.

6. Pest Infestations (Termites, Rodents, etc.): While some home inspectors are qualified to identify pests, a general home inspection may not be as thorough as a dedicated pest inspection. Termite damage, rodent infestations, or other pest-related problems can be easily overlooked.

   • How to Spot It: Look for signs of termites, such as mud tubes, damaged wood, or discarded wings. Check for rodent droppings, gnawing marks, or nesting materials. Schedule a separate pest inspection by a licensed pest control professional.

7. Mold and Air Quality Concerns: A home inspection might identify visible mold, but it won't typically include air quality testing. Hidden mold growth, asbestos, or radon gas can pose serious health risks.

   • How to Spot It: Look for musty odors or visible mold growth. Consider having an air quality test performed to check for mold spores, asbestos fibers, and radon gas.

8. Water Heater Age and Sediment Buildup: A home inspection will check if the water heater functions, but it might not assess its age or the level of sediment buildup inside the tank. An old or poorly maintained water heater can fail unexpectedly.

   • How to Spot It: Check the water heater's manufacturing date on the label. Listen for rumbling or popping sounds, which can indicate sediment buildup. Consider having a plumber flush the water heater to remove sediment.

9. Pool and Spa Issues: If the property includes a pool or spa, the home inspection may not be comprehensive enough to identify all potential problems. Issues like leaks, faulty equipment, or safety hazards can be overlooked.

   • How to Spot It: Look for cracks in the pool or spa shell, leaks around fittings, and proper functioning of pumps and filters. Ensure that safety features like fences and alarms are in place and functioning correctly. Consider a separate pool and spa inspection by a specialist.

10. Appliance Functionality Beyond Basic Operation: A home inspection typically confirms that appliances turn on. However, it may not thoroughly assess their performance or identify potential repair needs.

    • How to Spot It: Test all appliance functions, such as oven temperature, dishwasher cycles, and washing machine spin cycle. Check for unusual noises or smells during operation.
