Stonington's coastal exposure, roof by roof
Everything in Stonington is close to salt water. The Borough and the shore points take direct wind off Fishers Island Sound and the full force of nor'easters, which drive rain under shingle edges and into flashing. Salt corrodes galvanized flashing and fasteners and pulls granules from shingles sooner than inland. Mystic and Old Mystic are a little more sheltered along the river but damper, so algae streaks and moss show on shaded slopes. Pawcatuck is the same, with river humidity under tree cover. Snow is lighter than inland, but ice at the eaves still appears on the older houses with unheated attics.
