Repair or Replace? How Roofers Make the Call
The factors that tip a roof one way or the other.
NEWARK NEIGHBORHOOD · CLINTON HILL
An older roof leaking at the chimney, or a flat roof on a two-family that's past its time? Describe the roof.
Clinton Hill's roof problems change from block to block. It's one of the South Ward's two main neighborhoods, along with Weequahic, and Upper Clinton Hill has many historic single-family homes. Those older houses carry steep, detailed roofs where valleys, dormers and chimneys are the usual leak points. Lower down, two- and three-family houses carry flat or low-slope roofs where seams and parapets do the leaking.

Some older homes here have had decades of patching with roofing cement over flashing, which works for a while and then fails all at once. A proper repair replaces the flashing rather than adding another layer of tar.
Most calls here come down to roof repair, flat roofs, roof replacement, slate & older roofs, leaks & storm damage or gutters & flashing. The same number covers all six.
If a leak keeps coming back in the same spot after patching, the flashing underneath is usually the reason.
