When you're buying a home or managing a property, a structural inspection can mean the difference between a solid investment and a costly nightmare. But before hiring an inspector, you need to know whether they're actually covered if something goes wrong—or if their credentials are legitimate. Here's what you should verify before writing that check.
Why Inspector Insurance Matters
A structural, roof, and foundation inspector operates in high-liability territory. They're examining the bones of a building, and if they miss a critical defect—a cracked foundation, rotting roof trusses, or hidden water damage—you could face tens of thousands in repair costs. If the inspector was uninsured or unqualified, you'd have no recourse.
This is why verifying insurance and credentials upfront protects you from hiring someone who cuts corners or operates without protection.
Check Their Professional Liability Insurance
Professional liability insurance (also called errors and omissions insurance) is the baseline you need. This covers the inspector if they miss a defect or provide inaccurate findings that lead to property damage.
What to ask for:
- A current certificate of insurance listing professional liability coverage
- Minimum coverage amount (typically $250,000 to $1 million for structural inspectors)
- Confirmation the policy covers the specific services they're offering (foundation assessment, roof inspection, structural analysis)
Don't accept a vague answer. Request a copy of the certificate, not just a verbal confirmation. The certificate should show the policy is active and list the inspector's company name as the insured party.
Verify They Hold General Liability Coverage
General liability insurance protects against bodily injury or property damage during the inspection itself. If an inspector accidentally damages a gutter while accessing the roof or trips on a loose board and breaks something inside your home, this coverage handles it.
Standard limits run $1 million per occurrence. Check that their policy explicitly covers roof and foundation work, since some general policies exclude high-risk activities.
Look for Professional Certifications
Insurance alone doesn't guarantee competence. Verify the inspector holds relevant credentials from recognized bodies:
- American Society of Home Inspectors (ASHI) – requires ongoing training and follows a code of ethics
- National Association of Home Inspectors (NAHI) – similar standards and continuing education requirements
- International Association of Certified Home Inspectors (InterNACHI) – offers specialist certifications in structural and foundation assessment
- State licensing – many states require home inspectors to be licensed; check your state's real estate regulatory board
Ask the inspector which certifications they hold and in what year they were earned. Credentials older than 5–10 years may indicate they're not staying current with evolving building codes and inspection techniques.
Confirm They Carry Workers' Compensation Insurance
If the inspector employs staff, they must carry workers' compensation insurance. This protects their employees and also shields you—an uninsured worker injured on your property could potentially sue you instead.
Verify this is active if the inspection involves multiple people or equipment rental.
Ask About Their Inspection Standards and Scope
Before hiring, clarify exactly what's covered:
- Do they inspect interior and exterior foundation?
- Will they assess the roof from the ground or physically climb on it?
- Do they use specialized tools (moisture meters, thermal imaging, foundation crack monitors)?
- What's included in the written report—photos, measurements, repair cost estimates?
A $300 inspection that covers a visual walk-around is very different from a $600–$1,200 comprehensive structural assessment with detailed documentation. Knowing the scope helps you compare fairly and ensure the inspector's insurance actually covers the work they'll perform.
Red Flags to Watch
- No professional liability insurance certificate available
- Insurance amounts below $250,000 for structural work
- No verifiable certifications or licensing
- Unwillingness to provide references or past inspection reports (redacted for client privacy)
- Price significantly lower than local market rates—often indicates cut corners or inexperience
