What to Ask Your Home Inspector (and Why It Matters)

An inspection is your one chance to see a house the way a professional does: without the fresh paint, the staged furniture, or the excitement of finally finding “the one.” Showing up with good questions turns a quick walkthrough into a real education.

Plan to attend in person if you can. Inspectors are usually happy to explain what they find as they go, and seeing a problem firsthand makes it far easier to judge how serious it is.

Start with the big-ticket items

A few systems account for most of the expensive surprises. Ask about these first, while everyone’s attention is fresh.

  • How much life is left in the roof? Ask about its estimated age, its material, and any sign of past or present leaks, such as stained ceilings or damp attic insulation.
  • Is there anything wrong with the foundation or framing? Request that the inspector point out cracks, uneven floors, sticking doors, or walls that look out of plumb, and tell you whether each looks cosmetic or structural.
  • What shape are the heating and cooling systems in? Ask how old they are, when they were last serviced, and roughly how long they should keep running.

Follow the water

Moisture is behind a surprising share of home problems, so it deserves its own set of questions.

  • Where does rain go once it hits the roof, and does the ground slope toward or away from the house?
  • Are gutters attached, clear, and discharging well away from the foundation?
  • Do you see any signs of past or active moisture in the basement, crawl space, attic, or under sinks?
  • If there is mold, can you tell what is feeding it? The source matters more than the stain.
  • What condition are the supply lines and drains in, and is there any sign of slow leaks?

Check what’s behind the walls

  • Electrical: Is the panel modern and properly labeled? Are there ungrounded outlets, signs of overheating, or older wiring types that insurers dislike?
  • Plumbing: What are the pipes made of, and is the water heater near the end of its life? Is the water pressure normal?
  • Insulation and ventilation: Is the attic adequately insulated and ventilated? Are there drafts or cold spots you should know about?
  • Windows and doors: Do they open, close, and seal properly? Is there fogging between panes or visible rot in the frames?

Look for unwelcome guests

Ask the inspector to point out any gaps, chewed material, droppings, or wood damage. Pay special attention to the attic, crawl space, roofline, and exterior walls. Where wood-destroying insects are common, ask whether a separate pest inspection makes sense.

Tip: Ask the inspector to rank what they find: safety issues first, then major repairs, then routine maintenance. That ranking gives you a clear basis for deciding what to negotiate and what to simply budget for.

Don’t skip the paperwork questions

  • Were past renovations permitted and finished properly? Unpermitted work can become your problem after closing.
  • If you dream of adding a deck, garage, or accessory unit, what do local rules allow? Your agent or the local building department can confirm.
  • Which items fall outside a standard inspection (septic, sewer line, radon, chimney interior) and might deserve a specialist?

Before you leave

Ask what maintenance the house will need through the year and when each task is due, then request the written report with photos. Use it to decide whether to request repairs, ask for a credit, or walk away.
