It depends on the type of gutter, the material it is made of, and how well it is maintained. If you have metal gutters, they may only need to be replaced every 10-15 years. If you have vinyl gutters, they may need to be replaced every 5-7 years. If you have wooden gutters, they may need to be replaced every 2-3 years. And if you have plastic mesh screens over your gutters, they will probably need to be replaced every year or so.

It depends on the material of the gutters, but typically they should be replaced every 5-10 years.
