7 Home Inspection Red Flags That Can Raise Your Insurance Premium (Or Get You Denied Coverage)

If you've ever had a home insurance policy get canceled, non-renewed, or hit with a surprise premium increase after an inspection, you're not alone. Every year, insurance companies across East Texas tighten their underwriting standards, and the things they're looking for overlap heavily with what we look for during a standard home inspection.
At JMJ Home Inspections, we inspect homes across Tyler, Longview, and the surrounding areas every week, and we've started noticing a pattern: the same handful of issues that show up in our reports are the ones insurance carriers use to deny coverage or hike premiums. This post walks through the most common ones, why they matter to an insurer, and what you can do about each one.
Why Insurance Companies Care About Inspection Findings
Home insurance underwriting has changed a lot over the past few years. Rising claims from severe weather, aging housing stock, and litigation costs have made many carriers far more conservative about what they'll insure — and at what price. Many insurers now require a four-point inspection (roof, electrical, plumbing, and HVAC) before issuing or renewing a policy on an older home, and some will send their own inspector out after a claim to look for pre-existing conditions.
The bottom line: a full home inspection before you buy, sell, or renew coverage isn't just about knowing what you're buying. It's about knowing what an insurance company might use against you later.
1. Roof Age and Condition
Roofing is the single most common reason we see homes flagged for insurance issues. Most carriers in Texas want to see a roof that's 15-20 years old or newer, and some are getting stricter — capping coverage at 10-15 years for full replacement cost coverage, after which they'll only pay actual cash value (depreciated value) on a claim.
What we look for: missing or curling shingles, granule loss, exposed nail heads, soft spots, and flashing issues around chimneys and vents.
What to do: if your roof is approaching 15 years old, get a professional roof inspection before your insurance renewal date, not after a denial letter shows up.
2. Outdated or Recalled Electrical Panels
Certain electrical panel brands — most notably Federal Pacific Electric (FPE) and Zinsco panels — are known fire hazards and are an automatic red flag for many insurers. Some carriers will deny coverage outright if one of these panels is present, regardless of the rest of the home's condition.
What we look for: panel brand and age, double-tapped breakers, aluminum branch wiring, and any signs of scorching or overheating inside the panel.
What to do: if your inspection report identifies an FPE or Zinsco panel, budget for replacement. It typically costs far less than the cumulative premium increases (or coverage denial) of leaving it in place.
3. Polybutylene or Galvanized Plumbing
Homes built roughly between the late 1970s and mid-1990s sometimes have polybutylene ("poly-b") supply lines, which are prone to failure and are flagged by nearly every carrier that catches them. Older galvanized steel pipes are a similar concern due to internal corrosion and reduced water flow.
What we look for: pipe material at the water heater connections and under sinks, visible corrosion, and water pressure issues that hint at internal pipe degradation.
What to do: a full re-pipe isn't cheap, but partial documentation showing the plumbing has already been updated (or a plumber's letter confirming condition) can sometimes satisfy an underwriter without a full replacement.
4. Aging or Missing Water Heater Safety Features
Water heater issues are one of the most common — and most preventable — sources of homeowner insurance claims. Insurers pay close attention to water heater age (most want to see units under 10-12 years old) and proper installation.
What we look for: age (via the manufacture date on the data plate), missing or improperly routed temperature-and-pressure (T&P) relief valves, lack of a drain pan in homes where the water heater is in an attic or above living space, and improper strapping in areas prone to ground movement.
What to do: these are often inexpensive fixes. A missing drain pan or T&P discharge line can sometimes be corrected for under $200, which is a lot cheaper than a denied claim after a leak.
5. Foundation Movement
East Texas clay soils expand and contract significantly with moisture changes, which makes foundation movement one of the more common — and more feared — issues we document. Insurers are wary of homes with visible foundation distress because foundation claims are expensive and, in many standard policies, foundation movement from soil conditions may not even be covered at all.
What we look for: cracking patterns in brick veneer and interior drywall, door and window misalignment, sloping floors, and exterior grading that directs water toward the foundation instead of away from it.
What to do: proper drainage and consistent foundation watering (yes, watering your foundation in dry months) go a long way toward preventing new movement. If movement is already present, a structural engineer's evaluation can help clarify whether it's cosmetic or a genuine structural concern — information that matters a lot to an underwriter.
6. Wood-Destroying Insects and Prior Damage
Termite and wood-destroying insect (WDI) damage is a major concern for insurers, particularly in humid East Texas climates. Some carriers require a separate WDI inspection (often called a "termite letter") in addition to the general home inspection before binding a policy.
What we look for: mud tubes, damaged or hollow-sounding wood, evidence of prior treatment, and moisture intrusion points that attract insects in the first place.
What to do: address moisture problems (poor drainage, leaking gutters, wood-to-soil contact) proactively, since these are what invite termites in the first place.
7. HVAC System Age and Neglect
While less dramatic than a foundation or roof issue, an aging or poorly maintained HVAC system can still affect insurability, particularly if there's visible evidence of neglect (rust, refrigerant leaks, or improvised repairs) that suggests a broader pattern of deferred maintenance in the home.
What we look for: unit age, visible corrosion or leaks, condensate drainage issues, and whether the system appears to have been regularly serviced.
What to do: keep maintenance records. A documented service history can reassure an underwriter that a slightly older system is still a low risk.
How a Pre-Listing or Pre-Renewal Inspection Helps
Whether you're preparing to sell a home in Tyler, renewing your policy, or just want to know where you stand, a full home inspection before the insurance company gets involved puts you in control. You get to fix what's fixable on your own timeline and budget, instead of scrambling after a non-renewal notice or a denied claim.
At JMJ Home Inspections, we serve homeowners and homebuyers throughout Tyler, Longview, Bullard, and the surrounding East Texas communities. If you're buying, selling, or just want a clear picture of your home's insurability, we're happy to walk you through what we find and what it might mean for your coverage.
