Ponding Water, Roof Drains and Scuppers on Flat Roofs
Why water sits, where it should go, and what fixes it.
ELIZABETH, NJ · FROG HOLLOW
A flat roof that won't stop leaking in Frog Hollow? One call reaches a roofer.
Frog Hollow is one of Elizabeth's older neighborhoods close to downtown, with houses set near each other on narrow lots. When buildings sit that close, roofers have little room to work, and the gap between two houses can collect leaves and water that end up against a wall. Many of the houses here have flat roofs that drain toward the back or into a gap between buildings. What you see is a leak along an outside wall on the top floor, or a ceiling stain near the back of the building. What it usually means is a blocked drain or scupper, or water building up where the roof meets the neighbor's wall.

On close-built blocks, setup can take more time than the repair. A roofer may need a neighbor's permission to reach part of your roof, so ask early.
Pages owners here use most: flat roofs, roof repair and leaks, roof replacement, shingle roofs, porch and garage roofs, or finding a roofer.
If the house next door had its roof done recently, mention it. Work on one roof can disturb the flashing on the next.
