Flat Roof Replacement in Brick Church 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.
Here the flat roof is the whole roof, behind a street parapet, with internal drainage. Three things fail in order of likelihood: the outlet blocks, the coping opens up, and the upstand lets go. Getting onto it at all is the first item on the schedule.
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. Price the access and the hours, not just the roof. A route through a shop or an occupied flat, and trading hours that decide when work can happen, are both real constraints -- and the roof is usually flat behind the parapet rather than the pitch you can see.
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.
Flat roofs behind street-facing parapets are the Brick Church job, and access is the first problem rather than the roof: a roof reached through an occupied unit or a commercial tenancy needs somebody with keys to be part of the conversation before a date is set.
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.
Mixed-use changes the order of work.
Where the ground floor is commercial and the upper floors are flats, the building is still a multiple dwelling and the roof still has to be reached.
Where there is a pitched slope here it is usually a small street-facing section in front of a flat roof, and the transition between them is the interesting part.
Slate on a mixed-use building is usually confined to a street elevation, with flat roofing behind it.
Partial work here usually means the flat roof and not the pitch, or one section of a larger flat roof.
The three-unit line runs right through this city.
The largest houses, and where slate survives.
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.
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.
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.
Across separate structures, yes, and it is often the right answer -- a garage, a rear addition and the house are three roofs of three different ages. Across one roof, usually not: mobilization and waste cost much the same twice as once, you get a visible line where new meets weathered, and the half left behind ages through another winter.
An architectural asphalt roof in New Jersey runs $9,500 to $26,000, and on a typical 2,000 square foot house most people pay $12,000 to $18,000 installed. Per square foot that is $5.50 to $8.00 for architectural and $4.50 to $6.50 for three-tab. Slate is a different market entirely: $20 to $35 per square foot to replace an existing one.
