Three Family Roof Replacement in Presidential Estates from $9,500. Three units is where New Jersey changes its mind about your building, twice, for two unrelated reasons. Free inspection and a written quote.
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. That combination needs a scope that deals with salvage and matching as well as with tenant sequencing.
A three-family house is the defining building of this city and the least well served by roofing advice. Two things happen at that third unit and neither has anything to do with roofs. The ordinary-maintenance exemption in N.J.A.C. 5:23-2.7 covers one- and two-family dwellings, so a covering replacement becomes permitted construction work. And the building becomes a multiple dwelling under N.J.S.A. 55:13A-1 et seq.



The roofing costs what roofing costs, in the same New Jersey range. What changes at three units is everything around it: the ordinary-maintenance exemption no longer reaches the building, so the work is permitted construction, and the building is a registered multiple dwelling under N.J.S.A. 55:13A-1 et seq. on a five-year inspection cycle. 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.
The fee is modest; the filing and the closing inspection are days. Build them into the program rather than discovering them, and treat any contractor who says a three-family needs no permit with caution.
Written notice, an agreed parking plan, a waste route that does not block an entrance, and a section-by-section sequence that never leaves an occupied unit under an open roof overnight. That is slower than an empty house and it is not optional.
Mobilization, permit and waste cost much the same once as twice, and half a roof on a tenanted building carries the risk of the winter in between. Phasing makes sense across separate buildings, not across one roof.
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.
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.
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.
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.
Yes, in writing, and earlier than you think. They need to know when work starts, when the curb will be unavailable and which days are noisiest. It is also the practical difference between a four-day job and two weeks of interruptions, so it is in your interest as much as theirs.
No. Work is sequenced section by section so that anything opened is closed and made watertight the same day. If weather means a section cannot be closed, it does not get opened -- which is slower on paper and cheaper in practice.
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.
