Salt air and nor'easters at the river mouth: Old Saybrook roofs
The shoreline takes salt air and wind-driven rain from nor'easters and tropical storms, which push water under shingles and flashing from angles ordinary rain never reaches and corrode exposed fasteners and metal. South-facing shore slopes age in full sun. Inland, the wooded neighborhoods trade wind for shade, moss and algae on north slopes and debris in valleys. Winters are mild by inland standards, but ice still forms at the eaves on warm-attic capes after a cold snap, and the river mouth adds fog and damp.
