A wind and hail deductible is not the same as a standard deductible, and the difference matters most after a storm. Standard deductibles are flat dollar amounts. Wind and hail deductibles are often percentage-based, calculated from the insured value of the property — not the size of the loss. On a $500,000 home with a 2% wind/hail deductible, the out-of-pocket amount is $10,000 regardless of whether the damage is $15,000 or $150,000. For HOAs and condo associations insuring multi-million-dollar buildings, the numbers scale accordingly. This guide explains how wind and hail deductibles work, how they affect individual owners vs. HOA boards differently, and what loss assessment coverage does when the HOA deductible gets divided among unit owners. What Is a Wind and Hail Deductible? A wind and hail deductible is a special property insurance deductible that applies only when damage is caused by windstorms or hail. Unlike a standard deductible—which is usually a flat dollar amount—a wind and hail deductible is often percentage‑based , calculated from the insured value of the property. This distinction is critical, because it means the deductible is tied to the size of the building, not the size of the loss. Flat vs Percentage Wind and Hail Deductibles Flat (Dollar) Deductibles A flat deductible works the way many people expect: $1,000, $2,500, or $5,000 per claim Same amount regardless of storm severity Percentage‑Based Deductibles A percentage deductible is calculated using the insured value of the property: Home insured for $500,000 2% wind/hail deductible $10,000 out‑of‑pocket before insurance pays The damage could be $15,000 or $150,000—the deductible is the same.
