Stripped to the deck, then built as a system. Not a new covering laid over whatever is already up there.
Deck, ice barrier, underlayment, flashings, edge metal, ventilation, then the covering. Most roofs that fail early fail at a detail, not at the shingle — which is why a quote that only talks about the covering is a quote about a fraction of the job.
They share a trade and very little else. Which one it is decides the programme, the specification and the price.
A full tear-off and a new roof system, specified for the building it is going on rather than to whatever is cheapest on the van.
A new roof on new work: an addition, a dormer, a converted loft or a building going up from scratch.
Low-slope systems replaced with the falls corrected, not just the membrane renewed over the same standing water.
Asphalt shingle roofs stripped and rebuilt, with the layer count established before the quote rather than discovered during it.
Replacement after a specific weather event, documented while the evidence is still on the roof.
Two-, three- and multi-family buildings, where one roof is a shared decision and a tenanted building has to keep working throughout.
Everything before that hour is logistics. Everything after it is installation. That hour is the only time anyone sees what is actually being roofed over.
How many layers, what the covering is, and what the building has had done to it. The layer count alone can decide whether a tear-off is optional or mandatory.
Not to the previous covering. A new system laid over an old one inherits every defect underneath it and hides the evidence of them at the same time.
Soft, delaminated or rotted sheathing is replaced now, while it is reachable. This is the single most common reason an honest quote carries a stated allowance rather than one flat number.
Ice barrier at the eaves, underlayment, valley and penetration flashings, edge metal, then the covering. Most premature failures are a flashing detail, not a shingle.
Intake at the eaves and exhaust at the ridge, balanced. A sealed roof deck with no path for air cooks the covering from underneath and shortens its life regardless of what it cost.
Newark is the largest city in New Jersey — 311,549 people across 24.14 square miles of land in 108,907 housing units. What that covers is genuinely different from one ward to the next: rowhouses shoulder to shoulder in the Ironbound, mansions on generous lots in Forest Hill, low-slope commercial behind parapets downtown, and two- and three-family blocks through the West and North Wards.
A replacement is specified for which of those it is, not for the city as a whole.
How we workWorth knowing before accepting any quote, because a scope that ignores these is a scope that will change later.
New Jersey adopts a single Uniform Construction Code and municipalities may not set lesser or greater technical requirements. A correct specification in Newark is correct in Kearny.
No more than two applications of covering may remain on a structure. A third means a full strip, whatever the quote assumed.
Replacing more than a quarter of a roof surface within any twelve months requires a construction permit. Splitting one job in two inside that window does not avoid it.
Required in this design zone, running from the eave edge to at least 24 inches inside the interior wall line.
In Newark the code is enforced by the city's Department of Engineering, Division of Construction Code Enforcement, which is where permits for qualifying work are issued.
Where a permit applies, the work is inspected at stages. A programme that ignores inspection windows is a programme that will slip.
Newark sits in a humid subtropical shading into humid continental (Koppen Cfa/Dfa) zone with a full freeze-thaw winter — the combination hardest on flashings, fixings and mortar.
Water that gets into a lap, a joint or a hairline crack and then freezes expands. Northern New Jersey cycles through that repeatedly each winter, so small defects do not stay small.
Melt moves slowly under a snow layer and refreezes at the cold eave, backing water up under the covering where pitch does not help. That is what the ice barrier exists for.
Rain coming in sideways gets under laps that shed vertical rain perfectly well, which is why edge and flashing detail matters more than the covering specification.
The five wards, plus the municipalities on every side — west into the Oranges, north into Belleville and Nutley, east across the Passaic River, and south into Union County.
General guidance about how these buildings are re-roofed, not a survey of any particular property.
Tear off, as standard. A covering laid over an old one inherits every defect underneath it, hides the evidence, and uses up the second of the two layers New Jersey permits on a structure.
Two. Where two applications of covering are already on a structure a third is not available, so the tear-off is required rather than a preference.
Yes. Replacing more than a quarter of a roof surface within twelve months requires a construction permit under the New Jersey Uniform Construction Code, and a full replacement is well over that. In Newark it is issued through the city's Department of Engineering, Division of Construction Code Enforcement.
Newark itself — the Ironbound, Forest Hill, Downtown, Weequahic, University Heights, Vailsburg, Roseville and Lincoln Park — plus Irvington, Belleville, Harrison, East Newark, Kearny, Hillside, Maplewood, South Orange, Orange, West Orange, Nutley, Roselle, Linden, Jersey City and Bayonne.
Because nobody can see the deck until the covering is off. Soft or rotted sheathing is replaced while it is reachable, and an honest quote states what that allowance covers instead of pretending the deck is fine.
