If you or a neighbor can get up on a ladder, i would suggest inspecting the gutter, and remove any built-up leaves, etc. If the gutter is clean then use a hose and spray some water in it while others look to see the leak. If the gutter is leaking, then after it dries out really well you should be able to seal the leaking seem from the inside. If the leak appears to be in the siding, etc, i would look to see if there are any nail or screw holes in that area as these are known to leak also, vertical seams in the gutter are known to leak and these are very common in corner areas. Finally, if this leaks only during rainstorms, make sure the roofing and drip edge actually over hangs the gutter and that rain water goes in the gutter and not down the drip edge and the siding.
Hope this helps.
