Insurance protects against unexpected losses during the policy period. An insurance policy is not a home warranty. If your roof has a finite lifetime and is approaching the end of its life, the cost of insuring your roof will be close to the cost of a new roof. If your insurance company is not allowed to increase your rate to match your risk (which seems to be the case in California), they will drop you as a customer. Your previous premium payments insured against the risk of unexpected loss during those earlier policy periods only. They have nothing to do with your current insurance rate.
