How a home inspection affects your insurance in North Carolina

A home inspection is for the buyer's benefit. But what the inspector finds will directly affect your ability to get insurance, and what it costs. Some findings can limit your carrier options or increase premiums significantly.

Roof age and condition

The single most important factor in NC home insurance pricing. Most carriers want a roof that's 15 years old or newer to offer standard rates. A roof that's 20+ years old may be surcharged, result in an ACV (actual cash value) settlement on roof claims only, or cause carrier declinations entirely.

Asphalt shingle roofs have a 20-25 year lifespan. A roof installed in 2000 is end-of-life in 2025. If the inspection reveals a roof in this range, budget for replacement, or factor it into your purchase negotiation.

Electrical panels

Certain panels are problematic for insurance. Two in particular:

• Federal Pacific Electric (Stab-Lok): Flagged by many carriers due to documented fire risk from breaker failures. Some carriers refuse to insure homes with these panels outright.
• Zinsco panels: Similar concerns. Found in homes built in the 1960s and 1970s. Many carriers require replacement before binding coverage.

If the inspection finds one of these, get quotes immediately. Some carriers will insure with a surcharge; others require replacement first. Panel replacement typically costs $3,000-$5,000.

Wiring type

Knob-and-tube wiring is found in pre-1950 homes. It's an older wiring type with no ground wire and cloth insulation that degrades over time. Many carriers won't insure a home with active knob-and-tube wiring. Some will with a surcharge if the wiring is intact and not overloaded.

Plumbing

• Polybutylene pipe (poly-b): Gray plastic pipe installed between roughly 1978 and 1995. Known for failure at fittings. Many carriers flag or decline homes with active poly-b. If the inspection finds it, some buyers negotiate replacement as a condition of purchase.
• Cast iron drain lines: Found in older homes. Can corrode over time. Some carriers surcharge for cast iron, particularly in older homes where lines may be near end of life.

Pools and trampolines

Both increase your liability exposure.

• Pools: Surcharges are common. An unfenced pool can make you ineligible for some carriers. Most require a fence with a self-latching gate.
• Trampolines: Flagged by many carriers. Some exclude trampoline liability entirely; others require removal as a condition of coverage. If you have kids, this matters.

Dogs

Certain breeds are excluded from liability coverage by many carriers, Pit Bulls, Rottweilers, German Shepherds, and others vary by carrier. If you own one of these breeds, disclose it upfront when getting quotes. Not all carriers exclude the same breeds, and an independent agent can find carriers that won't penalize you.
