Getting your house ready to sell often feels like a long to-do list. One of the most important steps? The home inspection. It’s a moment when a buyer learns what’s really going on behind the scenes — and sellers often find themselves surprised by what gets flagged. 

Understanding what home inspectors look for can help avoid delays or deal-breakers during the sale. Whether you're selling or buying, here’s what typically comes up and why it matters.

Roof Wear and Minor Damage

Buyers always look up. Home inspectors do too. "We frequently find loose or missing shingles, deteriorating flashing, or signs of previous leaks," shared Josh McCormick, President of HouseMaster, a Neighborly company. "These issues can raise red flags for buyers, even when they’re relatively minor."

Roof inspections often reveal signs of roof damage that sellers don’t even notice. Before listing, consider having a roofer or inspector check things over — especially if it’s been years since your last roof inspection.

Gutter and Drainage Problems

Water around the exterior is a big deal. Clogged gutters or downspouts that spill toward the foundation often suggest possible moisture problems. "Clogged gutters, disconnected or damaged downspouts, or water draining toward the foundation can signal potential moisture issues," adds McCormick.

Unchecked drainage problems can lead to water damage, which shows up clearly on a home inspection report. Cleaning out gutters, adding extensions, and fixing the grade near the house can help keep both buyers and their real estate agents confident in the property’s condition.

Outdated or Unsafe Electrical Components

Home inspectors frequently flag the electrical system. "We often see double-tapped breakers, missing GFCI outlets, or older panels that no longer meet safety standards," explains McCormick.

Even something as small as a loose outlet cover can show up in an inspection checklist. Updating these issues through a licensed electrician helps protect your deal and your buyer’s peace of mind. Faulty or outdated electrical work is one of the most common concerns noted in a home inspection report.

Plumbing Leaks and Corrosion

The plumbing system doesn’t need to be new — just working as expected. "Leaky faucets, slow drains, and corrosion on exposed pipes are all common findings," notes McCormick. "These are usually easy to fix ahead of time, and they go a long way in showing that the house has been properly maintained."

During the home inspection, signs of long-term plumbing problems can trigger questions about maintenance. Water pressure issues, mold growth under sinks, or rusted fixtures can all appear in the report. Buyers want to know the house has been cared for — and that includes your pipes.

HVAC Age and Maintenance Gaps

Buyers know HVAC systems are expensive to replace, so they want signs of upkeep. "If your system is older but still functioning well, that’s okay — but buyers want to see it’s been maintained. Change your air filters, clean vents, and consider getting a pre-listing tune-up," recommends McCormick.

Heating and cooling systems are a major part of any home inspection checklist. Clean filters, a recent tune-up, and documentation of service show that your mechanical systems are in good shape.

Attic Ventilation or Insulation Deficiencies

A hot or stuffy attic can signal energy problems — or worse, moisture damage. "Inadequate insulation or poor ventilation can lead to higher energy bills and potential moisture issues," shares McCormick.

Inspectors often check the attic for mold, pests, and signs of poor airflow. These issues can affect a home’s structural integrity or raise concerns about long-term costs.

Exterior and Foundation Concerns

First impressions matter, but so do cracks and gaps around the base of the house. "We often find minor cracks in foundations, loose siding, or weathered decks, especially in older homes," highlighted McCormick. "While hairline cracks are typically cosmetic, they can still alarm buyers if not explained properly."

Home inspectors often look for signs of structural issues that could lead to foundation problems. If caught early, small repairs can help a buyer feel better about the house’s overall condition. This is also a key place where the inspection contingency can come into play during the home buying process.

Quick Fixes That Can Make a Big Impact

While some problems need a professional, others are simple and budget-friendly. Consider tackling these before your inspection:

  • Replace missing or damaged caulking around windows and tubs
  • Reattach loose outlets or light switch covers
  • Touch up chipped paint and nail pops
  • Lubricate sticking windows or squeaky doors
  • Tighten handrails and banisters
  • Replace burnt-out light bulbs (inspectors note this)
  • Test smoke detectors and carbon monoxide alarms

Small things can add up to a big sense of care and maintenance. Buyers — and their real estate agents — often notice when a home feels well-kept from top to bottom.

FAQ

Can a home inspection lower my sale price?

It can affect negotiations. If an inspection report reveals major issues, buyers might ask for repairs, a credit, or a price reduction. That’s why addressing common problems before listing can help protect your asking price. A thorough inspection can also limit surprises later during the home appraisal process.

What happens if a home inspector finds safety hazards?

Buyers may back out if safety concerns are serious. Items like exposed electrical wires, faulty circuit breakers, or missing GFCI outlets can make buyers nervous. Most deals include an inspection contingency, giving the buyer a chance to renegotiate or cancel based on what turns up in the home inspection report.
