Six kinds of replacement work. Each one opens on its own page, where every area we cover it in is listed.
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.
Tear off, look at the deck, then build.
A new roof on new work: an addition, a dormer, a converted loft or a building going up from scratch.
Get the detailing right while it is still open.
Low-slope systems replaced with the falls corrected, not just the membrane renewed over the same standing water.
Fix the fall, then lay the membrane.
Asphalt shingle roofs stripped and rebuilt, with the layer count established before the quote rather than discovered during it.
Count the layers before quoting.
Replacement after a specific weather event, documented while the evidence is still on the roof.
Document the cause before it disappears.
Two-, three- and multi-family buildings, where one roof is a shared decision and a tenanted building has to keep working throughout.
One roof, several households, one plan.
Worth 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.
