What factors do home insurance companies consider when setting premiums?

There are many different factors that are taken into consideration when an insurance company is coming up with your premium, such as the age of your house, the materials used to build your house, the roof type and age of your roof, any updates that might have been made to your home, your credit score, home security systems, and claims. There are also liability exposures that can cause you to have higher premiums, such as owning a dog or having a swimming pool and/or trampoline.
