Home inspector reviewing checklist while examining a living room

Thinking of buying a home? It’s exciting—until you realize just how much can hide behind fresh paint and new carpet. The stakes are high. A missed crack or leaky pipe today could mean big headaches tomorrow. Every homebuyer deserves peace of mind before the keys hit their hand.

At Ashi's Inspectors, our goal is simple: empower buyers to see what matters most. This checklist isn’t about scaring you—it’s about giving you the tools to ask good questions, spot early warning signs, and feel confident at every step of your home_inspection.

Why Home Inspections Matter

A home isn’t just walls and a roof. It’s a system. Like a car, one worn belt or rusty pipe can affect everything else. The right inspection helps you avoid costly surprises and negotiate repairs before closing. According to the International Association of Certified Home Inspectors (InterNACHI), nearly 86% of buyers request a home_inspection for good reason.

The Essential Home Inspection Checklist

Let’s walk through the 15 areas every buyer should review—what to look for, common red flags, and smart questions to ask.


Exterior Inspection 🏡

What to Look For:

  • Cracks in siding or foundation
  • Peeling paint or warped boards
  • Damaged stucco, brick, or stonework
  • Rotten wood, especially near ground level

Red Flags:

  • Gaps around windows/doors (drafts, pests)
  • Unlevel walkways or steps (trip hazard)
  • Standing water near foundation (drainage issue)

Quick Tip: Walk the perimeter. Tap suspicious wood—if it sounds hollow, it could be rot.


Roof Inspection ⛅

What to Look For:

  • Missing, cracked, or curling shingles
  • Sagging rooflines
  • Moss or heavy debris buildup

Red Flags:

  • Water stains on ceilings inside the house
  • Rusted or damaged flashing

What to Look For:

  • Dampness or musty smells
  • Cracks in walls or floor
  • Efflorescence (white powder) on masonry

Red Flags:

  • Visible mold or mildew

DIY vs. Call a Pro

Some issues are easy to spot—a dripping faucet, a busted screen, a missing smoke detector. Others hide in plain sight, like slow leaks behind walls or wiring that doesn’t meet modern code. If you’re unsure about foundation cracks, roof structure, or anything electrical, it’s time to bring in a professional. Certified inspectors use specialized tools (like moisture meters and thermal cameras) and follow industry standards from groups like ASHI and InterNACHI.

What Pros Do On Arrival

A professional home_inspection begins with a methodical walk-through. Inspectors:

  • Review the seller’s disclosure and past repairs
  • Test GFCI and AFCI outlets
  • Use ladders and cameras to inspect roofs, crawl spaces, and attics
  • Check for signs of pests, water damage, and structural movement
  • Test heating/cooling systems, water pressure, and appliance operation

They’ll provide a detailed written report (with photos) highlighting key findings, safety concerns, and areas needing further evaluation.

Prevention & Maintenance

Think of your home as a living system. Regular TLC can save you thousands. Clean gutters every fall. Replace HVAC filters seasonally. Check for leaks after heavy rain. Inspect caulking around windows and doors every year. A routine Energy Efficiency Inspection near you can flag areas where insulation or appliances are costing you money.

Costs & Time Factors

A typical home_inspection takes 2–4 hours, depending on the home’s size, age, and condition. Specialized inspections (radon, mold, sewer scope) may require extra time. Costs vary by location and the scope of services—budget for specialty add-ons if the home has a pool, spa, septic system, or well.

When It’s an Emergency

If you find standing water in the basement, smell gas, or see exposed live wires, act fast. Shut off water or power if it’s safe. Call utility services or emergency responders. For carbon monoxide alarms, evacuate and call authorities immediately. Don’t wait—serious issues can escalate quickly.

FAQ

Q: Should I attend the inspection?
Yes! Walking through with your inspector helps you understand issues firsthand and lets you ask questions in real time.

Q: Can I do all this myself?
You can spot many surface problems, but only a professional has the tools and training to check systems behind the scenes.

Q: Are inspections required by law?
Not always, but most lenders and insurance companies strongly recommend a home_inspection before closing.

Q: What if the inspector finds problems?
You can negotiate repairs, request credits, or walk away—your contract and local laws will guide you.

Local/Seasonal Considerations

If you live in a region with heavy winter storms, inspect roofs and gutters every fall to prevent ice and water backup. In humid or coastal climates, check for mold and wood rot more frequently. For homes with wells or septic systems, schedule annual water quality and septic inspections as recommended by the EPA and state guidelines.


A home purchase is a major milestone. Equip yourself with the right checklist—and the right inspector—so you can move in with confidence, not worry.
