What Inspections Are Required to Insure an Older Home

The Four-Point Inspection

The four-point inspection is the standard insurance-required assessment for homes over a certain age, typically 25 to 40 years depending on the carrier and state. It evaluates the four systems that account for the majority of homeowners insurance claims: roofing, electrical, plumbing, and HVAC (heating, ventilation, and air conditioning).

Roofing: The inspector documents the roof material type, estimated age, general condition, and evidence of damage or deterioration. They look for missing or damaged shingles, sagging areas, granule loss, flashing condition around penetrations, and any signs of active leaks. The report estimates the remaining useful life, which the insurer uses to decide whether to offer full replacement cost, actual cash value, or no coverage for roof claims.

Electrical: The inspector identifies the wiring type (copper Romex, aluminum, knob-and-tube), the panel type (breakers or fuses), the total service amperage, and the overall condition of visible wiring. They check for signs of amateur work, exposed wiring, double-tapped breakers, and any code violations that are visible without opening walls. The electrical section is the one most likely to trigger a coverage denial, since knob-and-tube wiring and 60-amp fuse panels are common automatic disqualifiers.

Plumbing: The inspector identifies the supply pipe material (copper, PEX, galvanized, polybutylene, CPVC), the drain pipe material (PVC, cast iron, ABS), and the water heater type, age, and condition. They note any visible leaks, corrosion, or evidence of previous water damage. Galvanized supply pipes and polybutylene pipes are the most common plumbing findings that affect insurance eligibility.

HVAC: The inspector documents the heating and cooling system types, ages, fuel sources, and general condition. Oil-fired systems, very old furnaces (over 25 years), and systems with visible safety issues are noted. The HVAC section rarely causes outright denials but can contribute to premium increases if the system is nearing the end of its expected service life.

Cost and Logistics

A four-point inspection typically costs $100 to $300, with the price varying by region and the size of the property. The inspection takes 30 to 90 minutes and can be performed by a licensed home inspector, licensed contractor, or in some states, a certified insurance inspector. The inspector needs access to the attic (for roofing and wiring evaluation), the electrical panel, the water heater area, and any visible plumbing runs in basements, crawl spaces, or utility rooms.

Most insurers require the inspection to be completed within 30 to 90 days before or after the policy effective date. Some carriers accept inspections up to 12 months old if the report is from a licensed professional. If the home has had recent system upgrades (new roof, rewired electrical, repiped plumbing), bring documentation of those upgrades to the inspection so the inspector can note them in the report.

Wind Mitigation Inspection

In coastal states, particularly Florida, South Carolina, and Texas, insurers often require or strongly incentivize a wind mitigation inspection. This assessment evaluates the home's ability to resist wind damage from hurricanes and severe storms. Unlike the four-point inspection, which identifies problems, the wind mitigation inspection documents strengths that qualify for premium credits.

The wind mitigation inspection evaluates several specific features. The roof covering type determines how well the roof surface resists wind uplift and flying debris. The roof deck attachment method (staples, 6d nails, 8d nails, or screws) determines how well the roof deck stays connected to the trusses during high winds. The roof-to-wall connection (toenails, clips, single wraps, or double wraps) determines whether the roof structure stays attached to the wall framing. The roof geometry (hip roof vs gable roof) affects wind resistance because hip roofs perform better in high winds. Opening protections (hurricane shutters, impact-resistant windows, or impact-resistant garage doors) reduce the risk of wind-driven rain intrusion if a window or door is breached.

Homes that score well on the wind mitigation inspection can receive premium credits of 20% to 45% on the wind portion of their insurance premium. In states where wind accounts for 40% to 60% of the total premium, these credits translate to savings of $500 to $3,000 per year. The inspection costs $75 to $150 and is valid for five years.

Defensible Space and Wildfire Inspections

In states with wildfire risk, particularly California, Oregon, and Colorado, some insurers require a defensible space evaluation before issuing or renewing coverage. This inspection assesses the property's preparation for wildfire, including the clearance of flammable vegetation around the structure, the fire resistance of roofing and exterior materials, the screening of attic and eave vents to prevent ember intrusion, and the overall maintenance of the property's fire-resistant perimeter.

California's Safer from Wildfires program offers insurance discounts to homeowners who meet specific hardening criteria, including maintaining defensible space zones (0 to 5 feet of non-combustible material immediately adjacent to the structure, 5 to 30 feet of fire-resistant landscaping, and 30 to 100 feet of reduced fuel loads). Homes that meet these criteria can receive premium discounts and may qualify for coverage from carriers that would otherwise decline properties in high-fire-severity zones.

Property Condition Reports

Some carriers, particularly in the surplus lines market, require a comprehensive property condition report rather than a focused four-point inspection. This broader assessment covers the four-point elements plus the foundation, exterior siding and trim, gutters and drainage, walkways and driveways, and the overall structural integrity of the building. The report may also include photographs of the property's exterior and interior condition.

Property condition reports are typically more expensive than four-point inspections, ranging from $250 to $500, and take longer to complete (1 to 3 hours). They are most commonly required for homes over 50 years old, homes with known condition issues, or homes in markets where the carrier's underwriting team wants a comprehensive view of the property's overall risk profile.

How to Prepare for an Insurance Inspection

While you cannot change the underlying condition of your home's systems before an inspection, you can take several steps to ensure the inspection produces the most accurate and favorable report possible.

Clear access to the electrical panel, water heater, attic entry, and crawl space entry. Inspectors who cannot access these areas may note "unable to inspect" in the report, which insurers interpret negatively. Have documentation of any recent upgrades (new roof, rewiring, repiping, panel upgrade) available to show the inspector. Make sure the HVAC system is operational, since an inoperable system raises concerns about the home's overall maintenance level.

Address any obvious maintenance issues before the inspection: clear debris from the roof and gutters, repair visible water stains on ceilings, fix any dripping faucets or running toilets, and replace any exposed or damaged wiring that is accessible. These issues are inexpensive to fix but can negatively influence the inspector's assessment of the property's overall condition.
