Apartment Roof Replacement in Dundee from $5. A large flat roof over occupied units, where the sequence is worth more than the membrane. Free inspection and a written quote.
Converted mill buildings are the interesting case by the river: residential units under an industrial-scale roof, frequently with original structure and later plant on top. The roof is priced like commercial work and the occupancy is managed like residential, and both halves have to be in the program.
Apartment roofs here are large low-slope areas behind parapets, priced at the same $5 to $14 per square foot by system. The roofing is the straightforward part. What decides whether the program holds is everything around it.



Apartment roofs price at the same $5 to $14 per square foot by system. The roofing is the straightforward part -- what decides whether the program holds is resident notice, a parking and waste plan, and a sequence that never leaves an occupied unit under an open roof overnight. Priced per square foot rather than as a building, because the roofs here are mill-scale. What moves it is the plant on top and whether production below can continue -- and exposure by the water, which puts perimeter fixing on the list.
So the permit and its closing inspection are part of the program from the start rather than a question raised halfway through. That is useful: the inspection is independent confirmation that the specification was followed.
A blocked outlet on an apartment roof floods it rather than overflowing off an edge, and on a large roof there should be more than one. Surveying the drainage as a system beats replacing outlets like for like.
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. Separate buildings are a different and better case.
Dundee is where the large-area low-slope roofs are. A mill-era building carries a roof measured in tens of thousands of square feet with plant, curbs and ducting on it, and on those the membrane is the smaller half of the cost. Exposure by the water is the other factor: perimeter fixing matters more here than inland.
Two things move a Passaic price more than the covering does, and both are consequences of density rather than of roofing.
At 22,514 people per square mile the answer is rarely simple. No side yard, usually no driveway, and a dumpster that has to go on the street with an arrangement. Material up the frontage and waste down it is labor, and a quote that does not mention it has either absorbed it or not thought about it.
An attached building has no eaves. Water leaves through an internal outlet or a scupper cut through a parapet wall, so the failures are at the coping, the upstand and the outlet. A roof quote covering the field and silent on those has priced the easy part.
A blocked outlet ponds the roof instead of overflowing off an edge. Water standing in a lap through a cold week expands and lifts it, then thaws and runs in through the gap it just made. Outlet capacity is the cheapest genuine upgrade on a roof here.
Scale changes the arithmetic by the river.
Large-area low slope is the whole job by the river, and at that scale the insulation specification and the attachment method matter as much as the membrane.
At mill scale black EPDM starts to give ground.
Very little shingle by the river -- the workers' housing that has it is the exception among industrial buildings.
This is the genuine commercial roofing in the city: mill-era buildings with roofs measured in tens of thousands of square feet, plant on them and production underneath that cannot stop.
No side yard, no driveway, parapets on every side.
Semi-detached and pitched. Eaves are back in play.
The tightest frontages, and party-wall junctions.
The shop below decides the hours and the route.
Bus routes and loading bays. Arrange the street first.
A more open grid, so a dumpster needs no negotiation.
Detached houses, side access, sometimes no permit.
The questions that decide this job, answered up front.
Yes, in writing and earlier than you think. They need to know when work starts, when the curb is unavailable and which days are noisiest. It is also the practical difference between a week's job and two weeks of interruptions, so it serves you as much as them.
No. Work is sequenced section by section so anything opened is closed and watertight the same day. If weather means a section cannot be closed, it does not get opened -- slower on paper, cheaper in practice.
At an edge, almost certainly. An attached building has no eaves, so water leaves through an internal outlet or a scupper through the parapet -- and the failures are at the coping on top of the wall, at the upstand where the membrane turns up it, or at the outlet itself. The field is usually the last thing wrong with a roof here.
Rubber means EPDM, at $5 to $9 per square foot: bonded with adhesive and tape, black, and the least expensive single-ply. TPO is $6 to $12, welded at the seams and reflective, which matters on a large roof over occupied space. On a small rear addition EPDM is usually the right answer rather than the cheap one.
Two to five days on a house, four to seven on an apartment building, and one to three weeks on real commercial work. The roofing is rarely the long part: the street arrangement, the route onto the roof and any tenant notice periods are what set the start date in this city.
The route to the roof established before anything is priced. New Jersey figures, with the access stated rather than buried.
