Slate Roof Replacement in Irvington 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.
Slate on a three-family house raises a specific problem: any work involving scaffold and salvage over occupied units takes longer, and slate cannot be rushed without breaking it. The honest schedule for a re-slate here is longer than for asphalt, and it should be stated rather than promised away.
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. Assume permitted work and price the tenant logistics, because three-plus units is the default here. Rear sections at a shallower pitch are the other thing to watch -- they belong in the quote as their own area rather than averaged into the main roof.
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.
Irvington has a high proportion of three-unit-and-up buildings, so permitted work and multiple-dwelling status are the default rather than the exception here. That makes the paperwork predictable, and it makes the tenant logistics the part of the job worth planning properly.
Two clocks run on this work in this city and only one of them is about the weather.
Northern roofs fail at the edges in the freeze. Water backs up under the courses at the eaves, freezes, lifts them, and the ceiling below stains during the first thaw -- so the calls arrive in a cluster, in the same two weeks, and the roof that could have been done comfortably in September becomes an emergency in February.
Assume permitted work in Irvington and you will usually be right.
This is the default building in Irvington rather than a special case, and it shows in how straightforward the process is: the permit is expected, the building is already registered, and the only real variable is how well the tenant arrangements are made.
With so many three-plus buildings, most Irvington flat roofs are over occupied units, and that decides the sequence rather than the specification.
On a three-family house the roof is bigger than the frontage suggests and frequently has a rear section at a shallower pitch.
On a multi-building property, partial means by building rather than by slope: worst roof first, the rest scheduled.
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.
Flat roofs behind parapets. Access comes first.
Same buildings, a different construction office.
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.
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.
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.
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.
