Six towns, and what each one looks into

Town	What its page covers
Warren	A township split by the Second Watchung Mountain, with about 5,560 homes on the ridge and in the valley
Watchung	The first Watchung ridge, Stony Brook running down to Watchung Lake, and about 2,470 homes
Green Brook	A brook that runs 15 miles to the Raritan, and about 2,430 homes
Bridgewater	The largest of the six, with about 16,975 homes and the Raritan River along its southern edge
Bernards	Basking Ridge, the Passaic River on the east side and the rain gauge reading from Ida
Long Hill	The Great Swamp refuge to the north, the Passaic to the south and 7.65 inches of Ida rain

Before the call: six short answers

Is a ladder trip part of the job?: No. The lawn, an upstairs window and the attic hatch show most of what a roofer wants to hear about.
Is a small stain worth a call?: Yes, if it is still there after the next rain. Mark its edge with a pencil line and add the date, then let the next rain answer for you.
Who makes the call when I rent?: Whoever owns the house. Roof work is theirs to order and approve, so pass your photos along and ask for a call back.
Which towns count?: Warren, Watchung, Green Brook, Bridgewater, Bernards and Long Hill. A call from outside those six is outside the area.
Can the phone call settle a price?: No. The contractor looks at the roof first, and the price follows the roof.
What shortens the first call?: The street address, which room shows water, a rough guess at the roof's age and a few pictures.

A township cut in two by a mountain

The Second Watchung Mountain runs east to west through the middle of Warren Township. North of the ridge the ground slopes toward the Passaic River and the Dead River. South of it is Washington Valley, where the East Branch of the Middle Brook runs. Warren's listed elevation is 509 feet.

That matters here because the nearest published weather normals come from the Somerville Somerset Airport station, about 8.6 miles away and only 105 feet above sea level. Its 1991-2020 figures add up to roughly 45.5 inches of precipitation a year, with lows at or below freezing on about 124 days. A ridge-top roof can see different weather than the airport does, so read the numbers as a guide, not a reading from your own chimney.

Three sights that mean 911 before anything else

Any wire that is down or dangling near the house counts as live.
Give it at least 30 feet and keep others away, then report it to 911 or the electric company: PSE&G is 1-800-436-7734 and JCP&L is 1-888-544-4877. Warren's township page names both as electric providers, so your bill shows which one is yours.
A ceiling that bulges, sags or drips without stopping may be holding water above it.
Get everyone, pets included, out of the room beneath it, then phone 911.
Water coming through a light fixture, or heading for an outlet, means leaving that room and phoning 911 once you are standing on dry ground.
The roof can wait; people come first.

Four moves that make a roof problem harder

Climbing up for a better view.
Wet shingles and frosty rungs cause falls, and NIOSH counts more than 100 ladder deaths a year across the United States. A roofer can learn most of what matters from what you see on the ground.
Pressing on a damp spot.
Wet drywall goes soft and can drop on you.
Tossing the evidence.
New Jersey's insurance department wants pictures of damaged property taken before anything is discarded, and every receipt kept.
Handing over the whole price at the start.
Following Superstorm Sandy, the asphalt roofing trade group urged a written proposal and wariness toward anyone demanding money in advance.

Why two roofs on one street get different quotes

Four things move a quote before anything else. Size and slope set the labor. Layers matter: when the whole covering comes off, FEMA's sloped-roof fact sheet calls for an upgraded underlayment before the new covering goes on. Chimneys, valleys and vent pipes add flashing work. And the boards underneath only show their condition once the shingles are lifted.

The first number in any quote comes from the contractor, not from Crown Roofing and not from anything printed here. The quote guide goes through the factors one at a time.
