Leave it and get help if

Gusts are tearing shingles or boards loose: get family and pets away from the house and from the lawn beneath the eaves, and call 911 if material is falling.
A ceiling is bowing or the roofline sags: vacate the rooms underneath, and dial 911 if anything drops.
A downed wire touches the roof, or a tree leans on the house and the lines: treat it as live, keep well away, then call 911 and the electric company.
A wet or icy roof is no place to measure or look around: stay on the ground, and dial 911 after a fall.

Four questions that make two roof quotes comparable

How far down does the tear-off go?
In the Department of Energy's brief, roofing comes off to the sheathing in damaged areas; whether a quote strips the whole roof or covers over it is worth settling in writing.
What goes down first?
Ask for the underlayment by type: 30-pound felt, two layers of 15-pound felt, or a peel-and-stick membrane.
How is the deck handled?
The brief specifies decking rated 32/16 and at least 5/8 inch thick when a deck is replaced in full.
What happens to the vents and the flashing?
Reused or replaced, they decide where the next leak could start.

What moves the number on a full roof

Roof area and pitch set the basic amount of work, and the number of old layers decides how long the tear-off runs. A deck that is soft in places needs boards replaced before anything goes over it. The underlayment choice matters, since the Department of Energy's brief notes that peel-and-stick costs more than felt.

Chimneys, skylights and valleys add flashing work, and a ridge vent adds its own line item. No figures belong here; ask each roofer to itemize those pieces.

What it looks like

Shingle edges curling or cupping across most slopes, not just one
Grit from the shingles collecting at the downspout outlets
Stains in more than one room, or stains that come back after a patch
Daylight coming through gaps between the roof boards as seen from the attic
Shingles that crack when a roofer lifts them for a repair

Underlayment first, then rows from the eave

The roll beside the roofer is underlayment, the sheet that goes onto the bare deck before any shingle. Rows of shingles then start at the eave and climb. FEMA's sheet describes the first row, the starter strip, as shingles with the tabs cut off, set 1 to 2.5 inches from the eave.

Each course after it covers the nails of the one below.

Call (732) 568-2812 and give the street, the roof's age and the spot where water shows; the contractor arranges the visit.
Looking over every slope for curling, cracking and missing shingles.
Counting the layers of shingles already on the roof.
Checking the roof boards for soft spots from the attic side and at the edges.
Looking at the flashing, the vents and the gutters that a new roof would touch.
Explaining the options: a full covering, a partial one or a patch, and the order the work would follow.

Asked at the door

How urgent is a roof that is simply wearing out?

Leave the house and call 911 if a ceiling sags or shingles are flying. Leaks in more than one room are a call for this week: dial (732) 568-2812. An old roof that is not leaking can be planned for a dry stretch, and dated photos taken now show whether anything is changing.

What goes on between the old shingles and the new ones?

In the Department of Energy's brief, bad roofing comes off to the sheathing and damaged boards are replaced. Underlayment goes on next: one layer of 30-pound felt, two layers of 15-pound felt, or a peel-and-stick membrane. FEMA's shingle sheet adds roofing nails, not staples.

Do Iselin and Edison roofs get the same answer?

Yes, the line covers the Iselin page and the Edison page too. Edison's houses are younger by the Census median, 1975 against 1959, so a roofer there may find fewer layers. Have the address and how old the roof is ready, then call (732) 568-2812.

From the boards to the ridge, layer by layer

Sheathing: The deck of boards or panels that everything else is nailed to.
Underlayment: Felt or a peel-and-stick membrane; the Department of Energy's brief says peel-and-stick reduces water intrusion if shingles are lost and is widely used in valleys.
Starter strip: The first row at the eave.
Shingles: The visible layer, nailed through the nailing strip.
Ridge vent: The brief favors baffled ridge vents, and vents set off the ridge, over unbaffled ones that can let wind-driven moisture into the attic.

Looks you can take

Find the roof's age in your papers: a sale record, an old invoice, or a neighbor whose house was re-roofed the same year.
From the lawn, compare the slopes and note which one looks worst; a roofer will ask.
Count the stains inside and list the rooms with dates, newest last.
From the attic hatch with a flashlight, look for daylight, dark streaks and insulation that is matted and damp.

Paperwork for a whole roof

The state's 2018 notice on ordinary maintenance counts even total replacement of roof covering as maintenance, not permit work, for one- and two-family houses that share no wall with another building. The state's construction codes were updated in August 2026, and the notice says maintenance is still held to code. Edison's page states that replacing roofing needs a construction permit. Papers to ask for sets the two side by side.
