Roofing in Green Brook, NJ: A Brook With a Flood History
How long is Green Brook's memory for floods? The flood-control project's history lists high water in 1971, 1973, 1999, 2007 and 2011, and the brook that names the township rises in the Watchung Mountains and runs about 15 miles to the Raritan. A roof never floods, yet its gutters empty onto that same ground. Call (908) 827-6709 if a stain or a storm-torn corner worries you. Storm and wind damage is the place to start.
The houses here
Census Reporter's 2024 profile counts 2,432 housing units in Green Brook, give or take 228, and a median home value of $538,500, give or take $81,881. That margin is wide, so treat the median as a rough guide. It sits near Somerset County's $552,100 and well under the figures for Warren and Watchung. The profile offers no year-built breakdown.

Details worth writing down before calling from Green Brook
Gather the street address, which room shows water and the date you first saw it. Photos from the ground and from the attic hatch carry more than a long description.
Owner-occupants can call (908) 827-6709. If the house is a rental, forward the photos to the owner, who is the one to order roof work. A wire down goes to 911 or PSE&G first; the PSE&G tariff lists Green Brook as part of its service area.
Through the seasons
Summer storms and flood years in Green Brook
Summer is the wet half of the year at the Somerville station: June 4.23 inches, July 4.93 and August 5.18 on the 1991 to 2020 normals, against 2.20 in February. July averages 74.6°F with a mean high of 86.2. Wikipedia's account of the flood-control project ties two of the township's big floods to named storms, Floyd in 1999 and Irene in August 2011.
Storm season is also when a roof gets tested by wind and heavy rain. The roof condition check page covers a look after a hard one.
Where the water goes
A brook with its own flood-control project
The Green Brook rises in the Watchung Mountains, runs southwest about 15 miles and joins the Raritan at Bound Brook. The Green Brook Flood Control Project was first proposed in the early 1970s after repeated flooding. Washington Rock State Park, about 34 acres, lies in the township.
On ground like this, where a downspout empties matters. The EPA suggests steering it to a rain barrel or soil instead of a hard surface, and checking local rules first. The gutter repair page describes how a visit looks at the run and the landing spot.
