What is the purpose of an insurance deductible?
Three jobs a deductible does
- Lowers premiums. Every claim has handling costs: an adjuster visit, an estimate, payments. Removing small claims removes those costs from everyone's premium.
- Shares the risk. Because you pay part of every loss, the insurer can offer broader coverage for the rest at a lower price.
- Encourages care. Owners who pay the first part of a loss tend to fix small problems and protect the house, which reduces losses overall.
How that shows up on a roof
Routine upkeep, such as replacing a cracked pipe boot or a few shingles that slid off an aging roof, is the owner's job, and policies exclude wear and tear for the same reason. The deductible extends that idea to covered losses: even when a storm causes the damage, you carry the first slice.
Why storm deductibles are different
Wind and hail can damage thousands of roofs in one afternoon. To manage that concentrated risk, insurers in hail prone states often use a separate wind and hail deductible, frequently a percentage of the dwelling limit, so it scales with the size of the home. See percentage wind and hail deductibles.
What it means for you
Know your storm deductible in dollars, keep that amount available, and use insurance for losses well above it. If the damage barely exceeds the deductible, a claim may cost you more in future premiums than it pays.
