Can I compare two quotes on the price per square?

Only if both are scoped the same way, and they rarely are. One may carry synthetic underlayment and ice-and-water at the eaves where the other assumes felt; one may price ridge cap to the manufacturer's high-wind schedule and the other by eye; one may name a rate for replacement decking and the other stay silent until the deck is open. Put the two scopes side by side line for line before putting the totals side by side.

Tear-off or recover — which is right?

A recover leaves the old covering in place and goes over it. It is quicker and it avoids disposal, but nobody sees the deck, the new roof inherits whatever is underneath, and the assembly runs hotter. It is also simply not allowed where two applications are already up. On most Ocean County housing from the 1960s and 1970s that question has already been answered by the previous owner.

How long does the work take?

A straightforward single-story ranch is commonly off and back on within a working day or two. A larger house with multiple planes, or one where the deck needs work, runs longer. Weather governs more of the schedule than anything else, because a deck that has been opened cannot be left open, so crews watch the forecast before starting a tear-off rather than during one.

What happens if the deck is bad?

It gets replaced, in sheets or in sections depending on how much of it is affected. Soft sheathing around a bathroom vent, rot at a valley or delaminated plywood under a long-standing leak are all things found at tear-off, because that is the first moment anyone can see them. A written estimate should say what the price per sheet is if decking is needed, so the number is agreed before it is discovered rather than after.

Can part of a roof be replaced?

Physically yes, and on a shore house where one slope faces the water it looks tempting. What you get is a color difference that will not weather out, a seam between two ages of shingle, and the rest of the roof arriving at the same point a few seasons later. It is worth doing where the roof is young and the damage local.

Roof Replacement Cost, Permits & Tear-Off

When a roof is finished

Roofs rarely announce themselves. A covering can be finished for several years before a stain appears on a ceiling, and by then the deck underneath has usually been wet through a few winters. The signals that matter show up earlier and lower down: granules in the gutters, bare asphalt on the slope facing the weather, edges gone brittle enough to curl, and tabs that lift and drop back without resealing. Any one of those past eighteen years is worth taking seriously.

There is a second clock running alongside the first. Insurers in the coastal New Jersey counties look hard at roof age, and past roughly twenty years an asphalt roof commonly draws an actual cash value endorsement in place of replacement cost coverage, a surfacing exclusion, or a non-renewal. That timeline does not care whether the roof is currently leaking.

The two-layer rule decides more than people expect

New Jersey follows the residential code on reroofing, and a roof recover is not permitted where the existing roof already carries two or more applications of any type of covering. In practice that means a house on its second layer has no third option: the next roof is a full tear-off to the deck. The question “can we just go over it” has often been answered already by whoever owned the house in 1998.

That rule bites hard here. Much of the housing across Toms River, Brick, Bayville and Manchester Township went up between the late 1950s and the late 1980s, which puts most of it two coverings deep. Counting layers is worth doing early, and it can usually be done from a ladder at the rake edge.

Permits: it depends on the building, not the price

Under N.J.A.C. 5:23-2.7 the repair or replacement of an existing roof covering on a detached one- or two-family dwelling is classified as ordinary maintenance, and no permit, inspection or notice to the enforcing agency is required for ordinary maintenance. Attached housing is not covered by that exemption. A townhouse, a duplex or a condominium unit needs a permit whether or not the work is like-for-like.

That distinction lands unevenly across this county. A detached ranch in Holiday City is exempt. A duplex a few streets away in Holiday City Silverton is not, and neither are large parts of Crestwood Village and the Leisure communities around Whiting in Manchester Township and in Lakewood. Structural work on the deck or the framing brings the permit back regardless of building type, which is one more reason the sheathing gets assessed while it is exposed.

What the work actually consists of

A recover skips stage 2 entirely. That is what makes it a gamble: on a recover nobody has looked at the deck.

Stage two is where a job either stays on its estimate or does not. Until the old covering is off, nobody has seen the sheathing, the flashing at the wall junctions or the condition of the valleys, and all three are places where a shore roof quietly deteriorates.

The rest of the sequence is less dramatic and just as important, and it is where a shore roof is won or lost: drip edge, underlayment laps, valley detail, step flashing woven at the walls rather than sealed over, and the fastening schedule the wind class calls for. Those are set out on the asphalt shingle replacement page.

What moves a roof replacement estimate

A figure quoted before anyone has measured is an average of other people's houses. A real estimate is built from these, roughly in the order they move the number:

Squares — roof area in hundreds of square feet, which is not the floor area of the house
Pitch, because past about 6:12 the crew slows down and staging enters the price
Planes, valleys, chimneys and pipe penetrations, since flashing is where the labor concentrates
How many layers come off, and the disposal that goes with two rather than one
Decking replaced at tear-off, which is why a rate per sheet belongs in the estimate beforehand
Wind class and fastening schedule, set by the design wind speed at the site rather than chosen

Ventilation is part of the roof

A great deal of the older housing here has a ridge vent added at some point with no matching intake at the eaves, so the ridge pulls conditioned air out of the house instead of moving it through the attic. The deck stays damp in winter and the shingles run hot in summer. Replacement is the one moment intake and exhaust can be balanced without extra disruption, so ask for the ventilation plan before material is ordered.
