Slate Roof Replacement in Elmwood from $15. Before you replace it: slate outlives its own nails, and that is usually what has actually failed. Free inspection and a written quote.
Less slate survives here than in the larger-house districts, so when it does appear the profile and size are less likely to be matchable from stock. That makes salvage the whole game: sound slate taken from a rear slope is the only exact match available, and it is free.
Replacing an existing slate roof runs $20 to $35 per square foot -- $40,000 to $70,000 on an average house -- because the old slate has to come off and be disposed of before the new roof starts. A new slate roof is $15 to $30 per square foot. Those numbers are why this page leads with an argument rather than a sales pitch.



Replacing an existing slate roof runs $20 to $35 per square foot -- $40,000 to $70,000 on an average house -- because the old slate has to come off and be disposed of first. A new slate roof is $15 to $30. Those numbers are exactly why this page argues against the job before it prices it. Access is the line to expect, and it is not padding. One route up, one route down for waste, and on a tenanted house a parking arrangement while the dumpster is on the curb. It also makes phasing worse value here than elsewhere, because mobilization is the expensive part.
Slate outlives almost everything fixed to it. On a pre-war roof the usual failures are corroded nails, which let slates slip, and rusted valley linings and flashings. All three are repairs, at a small fraction of a replacement.
A steep or cut-up roof, scaffold over occupied units, a slate size or color no longer quarried, and a deck that has to be renewed underneath. Slate work also cannot be rushed without breaking material, so the honest schedule is weeks.
Widespread delamination, slate soft enough to break in the hand, or a deck that has gone. We will say when that is what we found and show you the elevation it is true of, rather than asserting it.
Tight frontages are the practical constraint. Material goes up the front and waste comes down the front, so the sidewalk is part of the plan rather than an afterthought -- and on a three-family house with tenants, so is where they park while the work runs.
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.
Tight frontages set the logistics and the logistics set part of the price.
Three tenancies on a tight frontage is the hardest scheduling problem on this site.
Short runs are the Elmwood problem.
Low eaves close to a neighbor make the first three feet both the most vulnerable part of the roof and the hardest to work.
Tight sites make phasing worse than it looks, because mobilization is a bigger share of the cost when access is difficult.
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.
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.
Much cheaper up front -- $4.50 to $8.00 a square foot against $20 to $35 to replace slate -- and frequently the wrong decision, because a repairable slate roof has decades left. It is also irreversible on a period house. We will price both honestly and say which we would do.
Often, where the size and color are still quarried. Where they are not, the best match available is sound slate salvaged from a low-visibility elevation of your own roof -- which is why slate coming off is stacked carefully rather than treated as waste.
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.
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.
No. The inspection is free, the written quote is free, and neither carries an obligation. The survey also answers the unit-count and permit question in writing, which is worth having even if you use somebody else. What we will not do is give you a number at the curb without going up.
Unit count established before anything is priced. New Jersey figures, not a national calculator.
