Barn Roof Replacement in Frenchtown from $6. A big simple plane: cheap by the square foot, and the structure underneath matters more than the covering. Free inspection and a written quote.
Farm buildings within the borough are mostly former ones, surrounded now by other buildings, so the job is as much about craning, access and working above neighbors as it is about the roof. Worth establishing before a price rather than on the morning.
A barn roof is not a big house roof. It is usually one or two large uninterrupted planes, which makes it among the cheapest roofing there is per square foot and among the most expensive in total simply because there is so much of it. Panel metal over purlins is the normal answer and normally the right one.



Panel metal over purlins at $6 to $12 per square foot is the normal answer and normally the right one. A barn is among the cheapest roofing there is per square foot and among the most expensive in total, simply because there is so much of it -- which is why we quote a rate rather than pretend a typical barn exists. Town pricing rather than farm pricing. Close-set buildings, shared junctions and commercial frontage mean access, scaffold and working above somebody else's premises are real lines -- and on slate they push a per-tile price toward the upper end.
The structure. No insulation, no ventilation problem and no ceiling to protect means the consequence of years of water is in the purlins and rafters rather than on anybody's plaster -- and on a building this old that timber is often irreplaceable in kind.
Sound purlins at a spacing the new panel suits, a clear approach for a lift or scaffold, and a plane with nothing complicated on it.
Frame repair. Where the structure has moved or rotted, the covering is the smaller half of the job, and you deserve to know that before anybody quotes per square foot.
Town roofs rather than farm roofs: tight access, shared and abutting buildings, and low-slope sections behind frontages on the commercial street. The constraint is getting to the roof and working over somebody else's premises rather than anything about the covering.
A separate borough with its own construction office, and the only place on this site where access is harder than the roof.
Worth knowing before you start ringing round, particularly on a building with no ceiling under it.
Roofs in this part of New Jersey fail at the edges over winter -- water backs up under the courses at the eaves, freezes, lifts them, and the ceiling below reports it during the first proper thaw. Wind coming up the river valley does the rest, and on an exposed plateau property there is not much between a roof and the weather.
Town roofs rather than farm roofs: close-set older buildings, shared and abutting walls, and commercial frontage on the main street.
On abutting town buildings a repair frequently sits at a junction somebody else owns half of, and on the main street it may sit over a business.
Standing seam on a town building has to be detailed against neighbors, parapets and frontages rather than run out across an open plane.
Close-set town buildings make slate work slower and more careful, because there is nowhere for anything to fall that is not somebody else's property.
Behind the main street frontages there are genuine low-slope roofs over commercial space, with the access and trading-hours constraints that go with them.
Close-set buildings mean downspouts discharge within feet of a boundary or onto a shared surface, so where the water goes after it leaves the roof is part of the design and occasionally part of a conversation with a neighbor..
On abutting town buildings, part of the inspection is establishing what can actually be reached and what belongs to somebody else.

Barn country. A property is usually several roofs.
Two centuries of building, scattered widely.
The biggest roofs here. Price the frame first.
Asked on every job of this kind. Answered here.
Because that is where the damage is. A barn has no insulation, no ventilation problem and no ceiling to protect, so years of water went into the purlins and rafters rather than onto anybody's plaster. Standing underneath and looking up tells you what the job actually is; the view from outside tells you what the sheets look like.
It depends on what the building is used for, and it is a question for your township rather than for us. We will raise it before work rather than after, and each of the five municipalities in this service area answers it separately.
For a standard asphalt roof on an average house, yes -- that is well above the $12,000 to $18,000 most land at. For a large barn it can be entirely normal, because a barn roof is enormous even though the rate per square foot is the lowest of anything we do. And for natural slate at $22 to $35 a square foot it is unremarkable. The number on its own answers nothing; what the quote itemizes does.
In architectural asphalt, roughly $6,600 to $9,600 on New Jersey rates. But watch the units: 1,200 square feet of FLOOR is not 1,200 square feet of roof. Pitch, overhangs and dormers commonly make the roof area a third larger, and on a steep old farmhouse the difference is bigger still. That single confusion explains most quotes that look inexplicably far apart.
It is a Florida rule and it does not apply in New Jersey. The 25% rule comes from the Florida Building Code Existing Building, where repairing or replacing more than a quarter of a roof within a year can require the whole thing to be brought up to current code. New Jersey has no equivalent provision. It appears in searches here because national content repeats it without saying which state it belongs to.
