Trees, wind, and winter
Mature oaks and maples shade much of Bergen County, which is beautiful until a nor’easter brings limbs down on roofs and fills gutters with leaves. Shaded roofs stay damp longer, so moss and algae streaks are common on north-facing slopes. Winter freeze-thaw cycles work water into aging flashing, and towns along the Palisades and the Hackensack River see stronger gusts in big storms.
