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.
New large-span work is specified rather than improvised. The falls, the outlet positions and the mechanical penetrations are all designed before anything is ordered, because none of them is cheap to move afterwards.
Nearly eleven square miles at low density, mixing suburban residential streets with a very large industrial and refinery district.
Reference point: the city south of Roselle, stretching east toward the industrial waterfront.
The industrial roofs here are among the largest in the service area: single-span low-slope systems where the replacement is driven by drainage falls, mechanical penetrations and phasing around a working site.
On a plant roof the constraint is nearly always keeping the building operating, which decides the sequence before any roofing question does.

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.
The same job in the areas next door, and the other work we take on in this one.
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.
No. Large single-span roofs are phased so that whatever is stripped can be made watertight the same day, and the space underneath stays in use throughout.
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.
