The purpose of insurance is to shift the risk of loss to a company in exchange for a premium. Most policies have a deductible which is an amount the insured pays out of pocket before the insurance starts covering the cost of the loss.
In the process of managing insurance premiums, policy holders often consider adjusting their deductibles. Lower deductibles mean less money out of pocket if a loss occurs but obviously, results in higher premiums. Higher deductibles result in lower premiums but require that the insured bear a larger amount of the first part of the loss.
A small fire in a $300,000 home that resulted in $2,500 of damage might not be covered because it is less than the 1% deductible. If the homeowner can afford to handle the cost of repairs in exchange for cheaper premiums, it might be worth it. On the other hand, if that loss would be difficult for the homeowner, a change in the deductible could be considered.
It is a good idea to review your deductible with your property insurance agent so that you're familiar with the amount and make any changes that would be appropriate.
