The age of your home, roof, and materials are one of the most influential factors because they become more susceptible to damage from external and internal conditions as they age. Improvements made to your home can drive up your premium because they are more expensive for your insurance carrier to replace, so the cost of materials and construction for a home remodeling project will likely get figured into your rates.
Known in the insurance world as attractive nuisances, pools, and trampolines can increase your premium, along with wood-burning stoves and owning a breed of dog considered aggressive. Conversely, installing a home security system may reduce your premium.
Finally, previous claims can cause a spike in your premium because insurers perceive your home as a higher risk. If the claims start to stack up, you may lose your coverage altogether.
