A new roof on new work: an addition, a dormer, a converted loft or a building going up from scratch.
New work is the one case where the roof can be got right rather than merely made watertight. Ventilation paths, ice barrier coverage and the tie-in to the existing structure are all cheap to do properly while the framing is exposed and expensive to correct afterwards.
On new work the decisions that cause leaks ten years out are made before the covering is opened. Sequencing with the other trades matters more than the roofing itself.
An addition or a dormer is the one chance to build a roof properly rather than make an existing one watertight. Almost all of it is cheap now and expensive later.
Where new framing meets old, the two will move differently. The junction needs a flashing detail designed for that, not a bead of sealant across the joint.
An addition that blocks the original eave intake starves the whole roof of air. This gets designed while the framing is open or it does not get done at all.
From the eave edge to at least 24 inches inside the interior wall line. On a low addition with a shallow pitch that can mean most of the roof.
Dry-in has to happen before the interior work starts, and any penetration — flue, vent, mechanical — wants to be set before the covering rather than cut through it afterwards.
Drip edge, rake detail and the gutter line are the parts of new work most often left to the end and rushed. They are also where wind gets under a covering first.
On a detached house new work is mostly a sequencing question: get the addition dried in before the interior trades start, and make sure the new roof has not blocked the original eave intake.

Reference point: Weequahic Park, an Olmsted-designed park with a lake and a golf course.
Detached housing gives the simplest replacement in the city: the whole roof is reachable from its own ground, the tear-off can be staged on site, and the decking can be inspected fully once the covering is off.
Mature parkside trees mean more debris in valleys and gutters than elsewhere in the city, which shortens the life of whatever goes on if the drainage is not sorted at the same time.

All areas coveredWorth 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.

General guidance about how these buildings are re-roofed, not a survey of any particular property.
Everything that causes leaks in ten years is decided before the covering is opened: the tie-in to the existing structure, the ventilation path and the ice barrier coverage. All are cheap while the framing is exposed and expensive afterwards.
Largely, yes. On a detached building the eaves, rakes and valleys can all be reached and the layer count checked, which is why quotes on detached houses hold better than quotes on shared roofs.
Replacing more than a quarter of a roof surface within any twelve months requires a construction permit under the New Jersey Uniform Construction Code. A full replacement is over that threshold, so yes — and the work is inspected at stages.
Tell us what the building is and roughly how old the roof is. That is usually enough to say what the job involves before anyone goes up.
