Flat Roof Replacement in Doddtown from $5. EPDM, TPO or modified bitumen, priced per square foot, with the drainage looked at before the membrane. Free inspection and a written quote.
The age mix means two different flat roofs in one neighborhood. Older additions have marginal fall and fail at standing water; newer work has real fall and fails at a detail. Same service, genuinely different jobs, and the survey has to establish which before the system is chosen.
Flat roofing in New Jersey installs at $5 to $14 per square foot by system: EPDM $5 to $9, TPO $6 to $12, tear-off and insulation included. On a 1,500 square foot section that is $7,500 to $13,500 in EPDM against $9,000 to $18,000 in TPO.



New Jersey flat roofing installs at $5 to $14 per square foot by system -- EPDM $5 to $9, TPO $6 to $12, tear-off and insulation included. On a 1,500 square foot section that is $7,500 to $13,500 in EPDM against $9,000 to $18,000 in TPO. The variable here is the property itself rather than the neighborhood. With a century of building eras on one street, the deck, the covering and the layer count are all unknowns until somebody looks -- so a quote given without going up means very little in Doddtown.
Standing water 48 hours after rain means the fall is wrong or the outlet is blocked. In a freezing winter that water expands inside a lap and lifts it, then thaws and runs in through the gap it made. Re-covering over it buys a couple of seasons.
Parapets, copings and internal outlets, each of which has to be formed and flashed. Insulation, which is a real part of the cost and should be stated. And occupied units underneath, which decide the sequence.
EPDM is the least expensive and on a small rear addition it is frequently correct. TPO earns its premium on larger areas. We will say which applies rather than defaulting to the pricier one.
The mix is the point. A Doddtown street can carry a hundred-year-old slate roof, a post-war asphalt one and a recent build, which means a neighbor's experience is a poor guide here. Each property has to be established on its own -- covering, unit count and layer count.
One is about your building and one is about your covering, and most quotes in this city establish neither.
At one or two and detached, replacing a covering is ordinary maintenance under N.J.A.C. 5:23-2.7: no permit, no inspection. At three it is permitted construction work, and the building is also a registered multiple dwelling under N.J.S.A. 55:13A-1 et seq. on a five-year inspection cycle. Nothing about the roof explains that.
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.
A Doddtown street can carry a century-old roof, a post-war one and a recent build, which makes this the one area where asking a neighbor tells you nothing useful.
Because the housing eras are mixed, a Doddtown three-family can be anything from a purpose-built block to a house subdivided twice.
Layer count first in Doddtown, because on this mix of eras it is genuinely unpredictable.
Because the eras are mixed, a Doddtown slate roof may be original or may be a later replacement on an older house -- and the two age differently.
On a mixed-era property the sections are frequently different ages already, which is the best possible case for partial work.
The three-unit line runs right through this city.
The largest houses, and where slate survives.
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.
More urgent than in a warm climate. Water still sitting 48 hours after rain means the fall is wrong or the outlet is blocked, and in a freezing winter that water expands inside laps and under flashings and lifts them mechanically.
EPDM at $5 to $9 per square foot is the cheaper system and on a small rear addition it is frequently right. TPO at $6 to $12 earns its premium on larger areas. We will tell you which applies rather than defaulting to the pricier one.
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.
Usually not. Slate outlives almost everything fixed to it, and slipped slates on a pre-war roof normally mean the nails have corroded rather than that the slate has failed. Leaks at a valley usually mean a rusted lining. Both are repairs, and replacing an existing slate roof at $20 to $35 per square foot is a very expensive way to fix a nail problem.
Two to four days on site for a house, three to five for a three-family building, and one to three weeks for slate -- slate cannot be rushed without breaking material. Weather moves all of them and we will not dry-in a roof we cannot finish. Where a permit applies, the filing and closing inspection are days on top.
Unit count established before anything is priced. New Jersey figures, not a national calculator.
