About this app
Pass the NHIE on your first attempt. The National Home Inspector Examination has a 65% first-attempt pass rate. The candidates who fail are almost always weak in the same three areas: identifying defects across all major systems, component life expectancies, and standards of practice scope. This app is built around all three.
COMPONENT LIFE EXPECTANCY CHART
The most-tested reference topic on the NHIE. Know these cold.
Roofing: asphalt shingles 20-30 years, wood shingles 25-30 years, metal 40-70 years, tile 50+ years, flat membrane 10-20 years.
HVAC: gas furnace 15-20 years, central AC 10-15 years, heat pump 10-15 years, boiler 15-30 years.
Water heaters: tank 8-12 years, tankless 20+ years.
Plumbing: copper 50+ years, galvanized steel 20-50 years, PVC indefinite, cast iron drain 75-100 years.
Structural: wood framing indefinite if dry and pest-free, concrete foundation 75-100 years.
DEFECT SEVERITY GUIDE
Safety hazard: requires immediate action, poses risk of injury or death. Examples: open junction box with exposed wiring, missing GFCI near water, structural failure risk.
Major defect: significant in cost or function, affects intended use. Examples: failed roof with active leaks, non-functional HVAC, damaged foundation.
Minor defect or deferred maintenance: routine maintenance item. Examples: peeling caulk, dirty dryer vent, missing cover plate.
REPORT WRITING REFERENCE
Must inspect: structural system, exterior, roofing, plumbing, electrical, HVAC, insulation and ventilation, interior, fireplaces.
Not required to inspect: underground storage tanks, private wells and septic systems, low-voltage wiring, detached structures not connected to the main home.
Inspectors must disclose any systems that could not be inspected and state why.
1,000+ PRACTICE QUESTIONS
STRUCTURAL SYSTEM (15%): Foundation types (slab, crawlspace, basement, pier and beam), foundation defects (cracks, settlement, moisture), wood framing members, structural defects.
EXTERIOR AND ROOFING (20%): Grading slope away from foundation minimum 6 inches in 10 feet, siding types and defects, roofing materials and defects, flashing, gutters, windows, and doors.
ELECTRICAL SYSTEM (15%): Service entrance and panel requirements, double-tapped breakers, GFCI and AFCI required locations, aluminum wiring concerns, knob and tube wiring, ungrounded outlets.
PLUMBING SYSTEM (15%): Water supply materials, drain waste vent system, water heater safety (T&P valve, discharge pipe, seismic straps), fixture inspection, main shutoffs.
HVAC SYSTEM (15%): Furnace types and components, heat exchanger cracks (CO hazard), AC refrigerant lines, ductwork, filter condition, combustion air requirements.
INSULATION AND INTERIOR (10%): R-value requirements, moisture and mold indicators, bathroom ventilation, stairs and handrail specs, smoke and CO detector requirements.
PROFESSIONAL PRACTICE AND ETHICS (10%): Standards of practice scope and limitations, report content requirements, inspector liability, professional ethics, conflict of interest rules.
Every question includes a detailed explanation.
FREE: 5 questions per day, component life expectancy card, defect severity overview. No account required.
MONTHLY ($9.99/month): Full 1,000+ questions, complete Component Life Expectancy Chart, Defect Severity Guide, Report Writing Reference, reference library, exam simulator, 3-day free trial.
ANNUAL ($49.99/year): Everything in Monthly. Save over 55%. Best value.
LIFETIME ($49.99): One payment. Permanent access.
PASS PROMISE: Complete all questions with 80% or higher average, hold active subscription for 3 months, still do not pass. We extend your access by 4 months at no charge. voltexam.com/pass-promise
