4-Point Inspection Checklist: What Insurance Inspectors Need to Verify on Roof, Electrical, Plumbing, and HVAC

4-point inspections are narrow in scope and unforgiving in documentation.

The house may be simple. The report usually is not. One missing data plate, one weak roof note, or one unclear panel photo can turn a short insurance inspection into a resubmission job.

This checklist is built for inspectors who want a cleaner field process: what to verify on each of the four systems, what photos to capture before leaving, and how to write findings that survive carrier review.

The Fast Rule for 4-Point Work

For every section of the form, you need four things:

1. System identification
2. Age or date evidence where available
3. Current visible condition
4. Photos that support the answer

If one of those four is weak, the form becomes vulnerable to follow-up questions.

What a 4-Point Inspection Is and Is Not

A 4-point inspection is not a full home inspection.

You are not trying to document every defect in the house. You are focused on the four systems insurers care about most:

• Roof
• Electrical
• Plumbing
• HVAC

That limited scope is exactly why the inspection has to stay disciplined. The client expects a simple form. The carrier expects enough detail to trust the form.

A Field Order That Reduces Rework

Run the inspection in this order:

1. Roof and exterior roof evidence
2. Electrical panels and visible wiring clues
3. Plumbing materials, leaks, and water heater details
4. HVAC equipment, age data, and operating observations
5. Final photo check before leaving the property

That route keeps the photos grouped by form section and makes report assembly faster later.

1. Roof

The roof section usually gets the most scrutiny because insurers want current condition, remaining life context, and signs of higher claim risk.

Verify:

• Roof covering type
• Approximate age or permit history where available
• Visible wear, damage, patching, or deterioration
• Flashing and penetration condition as observed
• Active leaks, interior stains, or related roof-performance clues if part of the limited scope

Photo set:

• Each side of the dwelling
• Each roof slope where practical
• Close-ups of visible damage or repairs
• Any evidence that supports your remaining-life or condition call

Report example

"Architectural shingle roof observed. Visible wear and localized repair evidence were noted at the rear slope. No active leakage was observed at the time of inspection within the visible areas; however, roof-covering age and visible deterioration should be considered in underwriting and maintenance planning."

Keep roof language specific. "Fair condition" by itself is weak. State what you saw.

2. Electrical

The electrical section is usually where avoidable mistakes happen because the panel photos look fine until someone notices the details are missing.

Verify:

• Main panel brand and amperage
• Panel condition and visible corrosion or damage
• Breaker configuration and obvious double taps or other visible concerns
• Branch wiring type where observable
• Presence of subpanels if applicable
• Clear evidence of any known higher-risk components you observed

Photo set:

• Main panel exterior
• Panel interior with cover removed where safe and within scope
• Main breaker rating
• Any observed defect or notable condition
• Subpanel photos where present

Do not assume one panel shot is enough. If the carrier cannot identify the equipment from the photo set, your form is weaker than you think.

3. Plumbing

Plumbing on a 4-point is less about every fixture and more about risk-significant components and visible evidence.

Verify:

• Supply piping material where visible
• Drain/waste material where visible
• Active leaks or water-damage clues
• Water heater type, apparent age, and visible condition
• Shutoff accessibility or related notable limitations if relevant to the form

Photo set:

• Representative supply piping
• Representative drain piping where visible
• Water heater data plate
• Water heater overall condition
• Any visible leaks, corrosion, or failed components

Report example

"Water heater data plate indicates 2011 manufacture. Corrosion and moisture-related staining were observed at the upper connections. Recommend repair or replacement evaluation by a qualified plumbing contractor as needed."

You are not helping yourself by writing "plumbing functional" with no material or age support.

4. HVAC

The HVAC section looks simple until the system age, equipment count, and operating status get muddy.

Verify:

• System type
• Number of systems serving the home
• Condenser and air-handler identification
• Apparent age from visible data plates where available
• Basic operating status within scope
• Visible condition issues such as corrosion, damaged disconnects, or missing insulation at key areas

Photo set:

• Condenser overview
• Condenser data plate
• Air handler or furnace overview
• Air handler or furnace data plate
• Thermostat or operating verification context if useful
• Any visible deficiency

If the home has more than one system, make sure the photos and notes make that clear. Ambiguity costs time later.

The Minimum Carrier-Ready Photo Package

Before leaving, verify you have:

• Roof views sufficient to support covering type and visible condition
• Panel photos clear enough to identify brand and interior condition
• Water heater data plate and representative plumbing-material photos
• HVAC data plates for each relevant unit
• Close-ups of every condition that influenced a "no," "deficient," or cautionary answer

The cleanest 4-point files are usually the ones reviewed in the driveway before departure, not after you get back to the office.

What Usually Causes Rework

Most preventable 4-point rework comes from:

• Missing data plates
• Weak roof condition language
• Unclear panel photos
• No supporting photo for a noted defect
• Vague system-age calls
• Not separating multiple systems cleanly

The field work is rarely the real bottleneck. Missing documentation is.

What Should Be Weighted First in the Report

Put findings in this order:

• Safety hazards or visibly significant deficiencies
• Conditions affecting insurability or likely follow-up
• Age and service-life context supported by evidence
• Maintenance or lower-priority notes last

That order helps the form read like a professional risk document instead of a scattered house summary.

A Simple Narrative Pattern

Use this structure:

1. System and location
2. Condition observed
3. Why it matters to the inspection
4. Recommended action or next step

Example:

"Electrical: Main panel at garage wall. Condition observed: Corrosion and staining were visible within the panel enclosure at the time of inspection. Why it matters: Moisture intrusion at electrical equipment can affect reliability and safety. Recommended action: Further evaluation and repair by a qualified electrical contractor."

That pattern stays readable and avoids overexplaining.

Where ReportWalk Helps

4-point inspections generate short, form-sensitive observations tied to very specific photos. ReportWalk helps inspectors dictate roof, panel, plumbing, and HVAC notes while standing in front of the component, then pair those notes with the evidence before the next section starts.

That is what protects margin on 4-point work. Cleaner first-pass documentation means fewer follow-up calls, fewer clarifications, and fewer returned forms.
