Garfield homes, weather and why roofs here leak
Garfield is one of the most densely built towns in Bergen County. A lot of the housing is older two- and three-family homes set close together on narrow lots, many with flat or low-slope roofs in back, aging brick chimneys and decades of patches layered on top of each other. Because the houses are so close, most owners can't see their own roof from the street or the yard, so small problems tend to go unnoticed until water shows up on a ceiling.
The town sits along the Passaic River on its western edge, and the whole area gets the same North Jersey weather pattern: heavy summer thunderstorms that drive rain sideways under loose flashing, wind that lifts older shingles, and winters with repeated freeze-thaw cycles that crack old flat-roof seams and build ice dams at the eaves. Trees in older neighborhoods and near parks like Dahnert's Lake Park drop branches and fill gutters, which sends water back into fascia boards and roof edges.
That's why a good roof inspection in Garfield looks at the whole roof, the attic and the gutters, not only the spot that is dripping. On multi-family houses we also check every roof section separately, because a back flat roof and a front pitched roof often fail for different reasons.
