Why do my gutters overflow in heavy rain

My gutters don’t seem blocked but they still overflow in heavy rain. Do I have to hire a specialist for this?

"Could be ur downpipe blocked or if u have shallow flow gutters might not be able to stand the amount of water flow from ur roof like deep flow gutters"

"If your guttering is clear and persists to overflow then it is probably to do with the amount of rainwater the guttering is having to deal with. It sounds like you need deepflow guttering that can handle more rain flow."
