If your roof does not have a good overhang that effectively moves the water away from your foundation, then gutters may be part of that solution. Ultimately, your goal is to get the water away from your house: Sloping the land down away from your foundation is the first/ideal choice; French drains and other ground gutter systems are also other options... My old gutters used to get ripped off a lot because I used to have a bad insulation system in my roof and eaves: Ice dams build up at your roof edges and gutters and eventually the weight rips your gutters off. My "new" gutters are 7 years old now and still look like I just installed them because I also now have a standing seam roof with a ridge vent and properly installed insulation that allows a "cold gap" along the inside of the roof: Snow on the roof doesn't melt quick enough to form ice dams and slides off under its own weight... BONUS: Don't have to rake my roof anymore either.

TL/DR: If your present roof surface and roof insulation promotes the buildup of ice at the roof edges, you will regularly have to repair/ replace your gutters and eaves.
