A 4-point inspection on an older home evaluates four insurance-critical systems: the roof (type, age, remaining life, leaks), electrical (panel brand, amperage, wiring type), plumbing (supply-line material and water heater), and HVAC (heating and cooling age and operation). Insurers use it to gauge risk on homes roughly 25 to 40-plus years old before issuing or renewing coverage.
Why do older San Diego homes need a 4-point inspection?
Insurance carriers order a 4-point inspection because the failure risk of major systems climbs sharply once a home passes the 25-to-40-year mark. In San Diego County, where mid-century neighborhoods in La Jolla, North Park, Chula Vista, and Escondido are full of homes built in the 1950s through 1980s, carriers want proof that aging components won’t trigger a costly claim. The report is narrower than a full home inspection. It zeroes in on the four systems most likely to cause fires, water damage, or large payouts, so an underwriter can decide whether to issue, renew, or decline a policy.
What does the roof portion of a 4-point inspection cover?
The roof review documents the covering type, estimated age, remaining service life, and any visible damage or active leaks. On older homes this matters most, because many San Diego roofs reach the end of their useful life around 20 to 25 years. The inspector notes whether the roof is composition shingle, tile, or flat/built-up, and flags worn flashing, ponding, or prior patch repairs. If the roof is borderline, carriers often want a few more years of life remaining before they’ll write the policy. A dedicated roof inspection can dig deeper if questions remain.
What electrical and plumbing problems does it flag?
On the electrical side, the inspection records the panel brand, amperage, and wiring type, then checks the branch wiring for visible hazards. Older homes are where red flags surface: outdated 60-amp service, known problem panels, knob-and-tube, or aluminum branch wiring that insurers consider fire risks. On the plumbing side, the inspector identifies supply-line material (copper, PEX, galvanized, or polybutylene) and the water heater’s age and condition. Galvanized and polybutylene piping are common deal-breakers because they corrode or fail. We also note any visible signs of leaks or prior water damage so nothing gets overlooked.
How does the HVAC review affect insurability?
The HVAC portion documents the heating and cooling equipment’s age, type, and whether it operates at the time of inspection. Many older San Diego homes still run original furnaces or aging condensers, and a non-functioning or end-of-life system can stall a policy. While a 4-point report focuses on insurability rather than full performance testing, an aging system that still runs and shows no obvious safety concerns generally satisfies an underwriter. For a deeper look at heat patterns or hidden moisture behind walls, thermal imaging can be added.
How is a 4-point inspection different from a full home inspection?
A 4-point inspection is built for insurance underwriting, not for buyers evaluating an entire property. It covers only roof, electrical, plumbing, and HVAC, and it skips appliances, the structure, grading, windows, and dozens of other items a standard inspection includes. If you’re buying the home, you usually want both: a comprehensive buyer’s inspection for your own peace of mind, plus the 4-point report your insurer requires. Sellers listing an older property sometimes order one ahead of time to head off financing or coverage surprises.
