Check for Ice Dams
Water melting off the roof pools behind the ice and then seeps back up under the shingles. And sometimes water can work its way 5 or even 10 ft. back up under the shingles. Eventually it drips through the roof into the soffits (the outside overhangs), walls, and worst of all, onto your ceilings.
