How to Read a Home Inspection Report: Section by Section Guide
Your inspector hands you a 50-page report with hundreds of photos. Here is how to read it systematically so you know what actually matters before your contingency deadline.
How Inspection Reports Are Structured
Most inspection reports follow a standard structure regardless of which software the inspector uses (Spectora, HomeGauge, and ISN are the most common platforms). The report begins with a methodology section, moves through each system of the home, and ends with a summary.
Within each section, items are rated using a condition code. These codes vary by inspector but typically include:
| Rating | What It Means | Action |
|---|---|---|
| Safety Hazard | Poses immediate risk of injury or death | Address before occupancy |
| Deficient / Repair Needed | Does not meet current standards; needs correction | Prioritize by cost and impact |
| Monitor | Not currently a problem; should be watched | Note for future maintenance |
| Recommend Further Evaluation | Beyond scope of general inspection; specialist needed | Follow up before contingency expires |
| Maintenance Item | Routine upkeep deferred by current owner | Budget for; not a negotiating item |
| Functional / Satisfactory | Operating as intended, no deficiency noted | No action needed |
How to Use the Photos
Modern inspection reports include dozens or hundreds of photos. Do not skip them. A photo shows you the location, the extent, and the context of a finding in a way that a text description cannot.
When reviewing a finding that concerns you, look at the photo and ask: Is this isolated to one area, or does it appear throughout? Is this a surface condition or does it go deeper? Does the photo show active damage or historical damage?
If a photo is unclear or you cannot determine the extent of an issue from the report alone, call the inspector. Inspectors are available to clarify their findings after the report is delivered. That is part of the service you paid for.
Section-by-Section Breakdown
Summary / Executive Summary
The condensed list of all deficiencies found during the inspection. This is what most buyers read first and what agents use to draft repair requests.
Check whether the summary is organized by severity or just listed chronologically. Items in the summary still require review in the full report for context. A single-line summary item like 'moisture at foundation' could mean a minor efflorescence stain or active seepage — the full section will tell you which.
Do not submit the summary list directly as your repair request. It includes maintenance items and cosmetic findings that will irritate the seller and dilute your leverage on real issues.
Roofing
Covers the roof covering material, flashings, gutters, downspouts, skylights, and visible chimney condition from the roof level.
Look for the inspector's note on estimated remaining useful life. Also check whether the inspector walked the roof or viewed it from the ground with binoculars — noted in the report methodology. Ground-only inspections miss more than roof walks.
If the report notes any active leaks or recommends further evaluation by a roofing contractor, take that seriously. Inspectors are generalists — a roofer will give you a more specific assessment and a repair or replacement estimate.
Exterior
Covers siding, trim, windows, doors, grading, drainage, driveways, walkways, retaining walls, and attached structures like decks and porches.
Grading findings (water draining toward foundation) are extremely common and should not be dismissed as minor. Wood rot findings in siding and trim warrant clarification on extent — is it one board or half the wall? The photos are essential here.
Deck findings are frequently significant safety issues. Improper ledger attachment (where the deck meets the house) causes deck collapses. If the report flags deck structural concerns, get a contractor to evaluate before closing.
Foundation, Basement, and Crawl Space
Covers foundation walls, floor structure, sill plates, support columns, moisture conditions, and insulation in below-grade spaces.
Distinguish between cosmetic cracks and structural cracks. Vertical hairline cracks are common. Horizontal cracks, stair-step cracks in block, and cracks wider than 1/4 inch with offset edges require structural engineer evaluation. Also check moisture readings — inspectors use a moisture meter and note readings that exceed acceptable thresholds.
If the inspector notes wood rot at sill plates or floor joists, ask for photos and note the extent. Localized rot is a repair. Widespread rot is a structural remediation.
HVAC (Heating, Ventilation, and Air Conditioning)
Covers the furnace or boiler, air conditioning system, ductwork, vents, filters, and thermostat function.
Age and condition are both noted. An HVAC system near the end of its useful life is a financial issue even if currently working. A cracked heat exchanger in a furnace is a safety issue regardless of age. Check whether the inspector recommends evaluation by an HVAC technician — if so, follow up before your contingency expires.
HVAC systems are inspected under operating conditions. If the inspection is conducted when outdoor temperatures prevent AC testing (typically below 60 degrees Fahrenheit), the inspector will note that AC could not be evaluated. This is standard — not an oversight.
Plumbing
Covers supply pipes, drain and waste pipes, water heater, fixtures, hose bibs, and visible sewer connections.
Note the material type for supply pipes. Copper and PEX are current standard. Galvanized steel is found in older homes and corrodes from the inside — flow restriction develops over time. Polybutylene is a known failure material. The report will identify what the inspector could see; buried pipes and the main sewer line require separate testing.
A standard home inspection does not include a sewer scope. If the home is more than 20 years old or has mature trees near the sewer line path, order a separate sewer scope inspection. Main line failures cost $3,000 to $15,000 and are not covered by homeowners insurance.
Electrical
Covers the service entrance, main panel, subpanels, wiring type, outlets, switches, GFCI and AFCI protection, and visible junction boxes.
Panel brand matters. Look for Federal Pacific, Zinsco, or Pushmatic in the panel section — these have known defect histories. Also check for aluminum branch circuit wiring (common in homes built from the late 1960s through the 1970s) — aluminum wiring requires specific outlets and connection devices to be safe.
Electrical findings are disproportionately important. Electrical deficiencies are the leading cause of house fires. Safety-rated electrical findings should be addressed regardless of whether the seller cooperates — budget for them in your post-closing plan if necessary.
Interior
Covers walls, ceilings, floors, windows, doors, stairways, fireplaces, and smoke and carbon monoxide detectors.
Water stains on ceilings indicate past or present moisture intrusion from above. The inspector will note whether moisture readings are currently elevated (active) or appear dry (historical). Stair and railing deficiencies are safety findings even when they seem minor. Fireplace findings often require a separate chimney inspection for full evaluation.
Window seal failures (fogging between panes) are cosmetic, not structural. They are common and do not require inclusion in your repair request unless they are widespread enough to significantly affect insulation value.
Attic and Insulation
Covers roof structure, ventilation, insulation depth and coverage, and signs of moisture or pest activity.
Ventilation and insulation both affect energy costs and roof longevity. Check the insulation R-value noted against the recommendation for your climate zone. Also look for any mention of bathroom exhaust fans terminating in the attic — this is common, wrong, and causes moisture damage to the roof deck over time.
Attic access is often tight and inspectors note when access was limited. If the inspector could not fully evaluate the attic, consider requesting additional evaluation on specific concerns before closing.
How to Prioritize the Findings List
When you have finished reading the report, create your own three-tier priority list before talking to your agent about next steps:
Safety hazards and major system failures that affect habitability, insurability, or represent costs exceeding $5,000. These drive your negotiation request.
Maintenance items and aging systems that will need attention in the next 1 to 5 years. These inform your true cost of ownership and may affect your offer price calculation, but are not repair request items.
Cosmetic issues, minor maintenance, and informational notes that are normal for any occupied house. Do not include these in your repair request.
Frequently Asked Questions
Most home inspection reports for a standard single-family home run 30 to 60 pages. Larger or older homes can produce reports of 80 to 100 pages or more. The length is driven by the number of photos the inspector includes — which is a good sign, not a bad one.
Deficient means the item does not meet the current standard for function, safety, or condition. It does not specify severity — a deficient item could be a missing GFCI outlet ($50 to fix) or a failing roof ($15,000 to fix). Inspectors use this label broadly and it requires further context to prioritize.
The executive summary (also called the summary section or repair request list) is a condensed list of all deficiencies pulled from the full report. It is designed to be used as the basis for your repair request to the seller. Not all items in the summary will be equally important — review the severity rating and cost context for each.
Yes, but prioritize strategically. Start with the executive summary to get the full picture. Then read the detailed sections for any item rated as a safety hazard or major system concern. The narrative sections explain context that the summary omits — context that can change how you interpret a finding.
Inspection photos document the condition of what the inspector found. They show the location of the deficiency, the extent of damage or wear, and sometimes comparison views. Photos of electrical panels, roof conditions, and water damage are particularly important — they tell you whether the finding is localized or widespread.
