Buying or maintaining a home involves making sure the property is safe, efficient, and insurable. One of the most targeted and essential evaluations for homeowners, especially those with older homes, is the 4 point home inspection. This focused assessment gives insurance companies and property owners a clear understanding of the condition of four critical systems in a home. Understanding what a 4 point home inspection is—and how it differs from a full inspection—can help homeowners make smarter decisions and stay ahead of costly repairs.
Understanding the Purpose of a 4 Point Home Inspection
A 4 point home inspection is a limited-scope evaluation that focuses on the four major components of a home: the roof, electrical system, plumbing system, and HVAC (heating, ventilation, and air conditioning). Insurance companies often require this inspection for homes over a certain age—typically 25 years or older—before issuing or renewing a homeowners insurance policy.
The goal is to assess the overall condition and remaining life expectancy of these critical systems to determine the home’s insurability. Unlike a full home inspection which covers everything from doors to appliances, the 4 point inspection zeroes in on areas that are most likely to pose financial risk to insurers. More about how insurance providers use inspections can be found at the Insurance Information Institute.
Roof Condition and Expected Life Span
The roof is one of the most crucial aspects of a 4 point home inspection. Inspectors evaluate the type of roof (asphalt shingles, tile, metal, etc.), its age, overall condition, and estimated remaining life span. They look for signs of damage such as missing shingles, leaks, rot, sagging areas, and poor installation.
Insurers are particularly cautious with older roofs, especially if they show signs of nearing the end of their functional life. In many cases, insurance companies may deny coverage for homes with roofs older than 20 years unless they pass inspection and demonstrate they are still in serviceable condition.

Electrical System Safety and Functionality
The second area of focus in a 4 point home inspection is the electrical system. Inspectors look at the type of wiring used (aluminum vs. copper), the condition of the service panel, the presence of circuit breakers or fuses, and whether the home has any outdated or unsafe wiring.
Older electrical panels—such as those manufactured by Federal Pacific or Zinsco—are red flags due to their known fire risks. Inspectors will also check for signs of amateur modifications, exposed wiring, inadequate grounding, or overloaded circuits. Safety and compliance with modern electrical codes are key factors evaluated in this portion of the inspection. The National Fire Protection Association (NFPA) offers more on electrical safety.
Plumbing System Materials and Leaks
Plumbing is another essential part of the 4 point home inspection. Inspectors examine the type of piping material used (copper, PVC, galvanized steel, polybutylene), as well as its age and condition. They check for visible leaks, corrosion, and water pressure irregularities.
Polybutylene piping, which was widely used in the late 20th century, is a major concern due to its high failure rate and potential for causing significant water damage. Insurance providers may require replacement of these pipes before issuing a policy. Additionally, the inspector evaluates fixtures, water heaters, and visible drainage systems.

HVAC System Age and Performance
The fourth component of a 4 point home inspection is the HVAC system. Inspectors check the age, condition, and operation of both heating and cooling units. They assess whether the system is functioning properly, has been regularly maintained, and complies with current safety standards.
Ductwork is also reviewed for signs of leaks, blockages, or damage. If the HVAC system is older or malfunctioning, insurers may require it to be serviced or replaced. Energy efficiency and safety are two primary concerns in this portion of the inspection. For more on HVAC maintenance, see Energy Star’s guide.
How a 4 Point Inspection Differs from a Full Home Inspection
While a full home inspection covers virtually every accessible area of a house, the 4 point home inspection is streamlined and purpose-driven. It is not designed to identify cosmetic issues or minor defects but to report on major systems that impact a home’s safety and insurance eligibility.
Buyers of older homes often opt for both types of inspections—the full inspection to assess overall condition and the 4 point inspection to satisfy insurance requirements. Even if not required, a 4 point inspection can be a valuable tool for understanding the condition of key systems and planning for future upgrades.
When You Might Need a 4 Point Inspection
Most commonly, a 4 point home inspection is required when applying for or renewing a homeowners insurance policy on a home that is 25 years or older. Some insurers may request the inspection at 20 years, especially in areas prone to severe weather or with higher risk profiles.
In addition to insurance purposes, a 4 point inspection can be helpful for homeowners planning renovations, assessing maintenance needs, or preparing for the sale of a property. Knowing the state of your major systems allows you to proactively budget and negotiate with confidence.
