What the Sound does to Old Lyme roofs
Old Lyme lies where the Connecticut River meets Long Island Sound, and the weather arrives from the water. Salt air works on flashing, fasteners and shingle granules, and the beach communities get the strongest dose. Coastal wind and nor'easters drive rain sideways into roof edges and under lifted shingles, and the south and east slopes facing the Sound take the brunt. Behind the shore, the wooded lots around Black Hall and the Center are shaded and damp, which feeds algae streaking and moss. Snow is lighter here than inland, but ice still forms at the eaves of older houses with cold attics.
