A blocked gutter backs water under the first course of shingles and into the fascia. It is the cheapest failure to prevent and one of the most expensive to ignore.
Gutters are not about the gutters. They are about keeping water off the fascia, out of the soffit, and away from the foundation. When they stop doing that, the damage shows up somewhere else and gets blamed on the roof.
