Shingle Roof Replacement in Brick Church from $4.50. Architectural at $5.50 to $8.00 a square foot, three-tab cheaper, and the eaves detail that decides both. Free inspection and a written quote.
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. Shingle above, membrane behind, and a junction taking everything the pitch sheds.
Architectural shingle installs at $5.50 to $8.00 per square foot in New Jersey and three-tab at $4.50 to $6.50. On an average roof that is a few thousand dollars of difference, and it is the clearest case in this trade of a cheaper quote being a lesser roof rather than a better price.



Three-tab installs at $4.50 to $6.50 per square foot in New Jersey and architectural at $5.50 to $8.00. On pre-war housing there is a second variable that matters as much: what the shingle is going onto, because board sheathing and plywood are not the same job. 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.
Freeze and thaw drives water back up under the courses at the eaves, which is what an ice barrier is for. Its coverage is a measurable line on a scope and it is invisible once the roof looks finished.
The correct pattern in the correct zone is what survives a February gust, and it cannot be inspected afterwards. It has to be in writing beforehand.
Two coverings is the practical limit. A roof already at two is a tear-off whatever anybody quotes, so a cheap overlay price on a twice-covered roof is not a price.
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.
Slate outlives almost everything fixed to it. Slipped slates usually mean corroded nails; leaks at a valley usually mean a rusted lining. Both are repairs. Replacing an existing slate roof is $20 to $35 per square foot, so the difference between diagnosing that correctly and not runs to tens of thousands.
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.
Here the flat roof is the whole roof, behind a street parapet, with internal drainage.
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.
Architectural on most houses, and the difference is real: $5.50 to $8.00 per square foot against $4.50 to $6.50. It is heavier, handles wind better and lasts longer. Three-tab is defensible on a small simple roof or a building being sold shortly.
Frequently board sheathing rather than plywood, and that changes the job: boards with gaps between them hold a nail differently, and any that have to be made good are a real cost. It is established by looking, not by assuming, and it belongs in the scope.
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.
