It sounds like you may have a gutter failure, and that your soffit is damaged. This is a serious problem that should be repaired quickly. A gutter is designed to draw water away from your roof, but if the gutter has been installed incorrectly, or has been filled with leaves and debris, water will actually go back up toward the roof, and will leak over the side of the gutter. This damages your fascia board, and the soffits of your roof (the underneath overhang of your roof), and could lead to serious water damage in your house. Make sure that your gutters are clean, and have an inspection of your soffits to make sure they're still viable. Also, make sure you have no leaks in your attic, or on room walls closest to your roofline at that point. You may need a full replacement of your gutter system, the fascia board, and your soffits if the current situation persists.
