When hearing about hip roofs for the first time, you might think it is simply referring to roofs that look cool. While that can be the case, hipped roofs are ones that slope down toward the eavestrough. There are never any vertical surfaces with this type. There is a single point at the highest point of the roof where everything slopes down from there. They are incredibly popular with certain types of houses, so when you need a new roof installation to replace an old, worn out roof, consider getting a hipped roof.
