Partial Roof Replacement in Presidential Estates from $4.50. One slope, one structure, or one building of several -- priced with the fixed costs stated honestly. Free inspection and a written quote.
Larger houses here have natural divisions -- a main roof, a wing, a porch, a garage -- and that makes partial work honest rather than a compromise. On slate it is more than honest: doing one elevation properly with salvaged material beats a whole-roof decision made under pressure.
Partial work is priced from the same per-square-foot rates, and the warning that belongs with it is the one nobody volunteers: the fixed costs do not shrink. Mobilization, waste and a crew day cost much the same on a third of a roof as on all of it.



Partial work is priced from the same per-square-foot rates, and the honest warning is that the fixed costs do not shrink. Permit where it applies, mobilization, waste and a crew day cost much the same on a third of a roof as on all of it. Expect the widest spread on this site here, because the covering might be slate. An asphalt roof on one of these houses sits in the normal range; a slate roof does not, and the difference between repairing one and replacing it is tens of thousands of dollars.
Across separate structures or separate buildings, where the roofs are different ages anyway. A garage, a rear addition and the house are three roofs, and doing the worst one now is a real decision rather than a compromise.
Splitting one roof across two years. You pay mobilization twice, you get a visible line where new meets weathered, and the half left behind ages through another winter first.
New covering next to four-year-old covering does not match, even in the same product from the same batch. On a street elevation that matters; on a rear addition it does not, and that is usually where a partial makes sense.
This is where slate is most likely to still be on the roof, and where the expensive mistake gets made. On these houses the slate is frequently sound while the nails and valley linings have gone -- a repair, not a replacement, and the difference runs to tens of thousands of dollars.
One is about your building and one is about your covering, and most quotes in this city establish neither.
Slate outlives almost everything fixed to it. Slipped slates usually mean corroded nails; leaks at a valley usually mean a rusted lining. Both are repairs. Replacing an existing slate roof is $20 to $35 per square foot, so the difference between diagnosing that correctly and not runs to tens of thousands.
On asphalt, if the covering away from the leak still lies flat, holds its granules and is not brittle, the roof has life in it and a repair is the right job. A failed flashing or a split upstand is hundreds of dollars and is routinely produced as proof that the whole roof is finished.
Two coverings is the practical ceiling. A roof already at two is a tear-off whatever anybody quotes, and it takes two minutes to check at the rake edge. It is the fastest way to tell whether the quotes in front of you describe the same job.
Bigger houses, bigger roofs, and a real chance the covering is slate rather than asphalt.
A large pre-war house divided into three is the awkward case here, because the roof is substantial and possibly slate while the regulatory position is the multi-family one.
Flat roofs here are usually over a rear extension or a porch on an otherwise pitched house, which raises a useful distinction: re-covering the flat section may be ordinary maintenance, while rebuilding its fall is structural and is not.
Asphalt on these houses is usually a replacement for something else, and the something else was often slate.
This is where slate most often survives in the city, and where the expensive mistake gets made most.
The three-unit line runs right through this city.
Genuinely mixed eras. A neighbor proves nothing.
Duplexes divided into three, and the traces that leaves.
Tight frontages, tenants, and nowhere to park a dumpster.
Flat roofs behind parapets. Access comes first.
Same buildings, a different construction office.
Three-plus units is the default, not the exception.
The questions that come up, before you have to ask.
Not exactly, and anybody who says otherwise has not tried. Even the same product from the same batch reads differently against covering that has had four summers on it. We will tell you where that will show and put the new work where it matters least if there is a choice.
It can, and not in the direction people expect. A covering replacement on a detached one- or two-family house is ordinary maintenance whatever the area; the moment the work goes structural -- decking out wholesale, pitch altered -- it is permitted work. The scope decides it, not the percentage.
Yes. The ordinary-maintenance exemption in N.J.A.C. 5:23-2.7 reaches one- and two-family dwellings, so at three units a covering replacement becomes permitted construction work with an inspection at the end. There is a second consequence as well: at three units the building is a multiple dwelling under N.J.S.A. 55:13A-1 et seq.
A building with three or more dwelling units is a multiple dwelling under the Hotel and Multiple Dwelling Law. It is registered with the DCA Bureau of Housing Inspection and inspected on a five-year cyclical basis, with a certificate of inspection filed afterwards. It is an ongoing maintenance regime rather than a one-off approval, and it applies whether or not anybody is doing work.
Because most online figures are national and this is not a national market. New Jersey pricing is $9,500 to $26,000 for an architectural asphalt roof, and a good part of the difference is detailing a warm climate does not need: ice barrier at the eaves, drip edge, and the nailing to survive a February gust.
