Flat Roofing in Lodi from $5. $5 to $14 a square foot by system, and the drainage decides whether it lasts. Free inspection and a written quote.
On the effectively-attached houses here the flat roof drains through a boundary parapet, which raises a practical question worth settling early: whose scupper is it, and does correcting the fall mean working over a boundary. Those are conversations, not obstacles, but they are cheaper had in advance.
Flat roofing installs at $5 to $14 per square foot in New Jersey: EPDM $5 to $9, TPO $6 to $12, tear-off and insulation included. Across these towns it turns up in two very different forms and they need different thinking.



Flat roofing installs at $5 to $14 per square foot by system, tear-off and insulation included. Across these towns it appears in two forms: the whole roof on attached stock, and a rear addition on suburban stock. They fail differently and need different thinking. The least predictable town covered here, and the reason is worth knowing: some houses have proper eaves and gutters while others are effectively attached with a parapet at the boundary. A quote given before establishing which means very little.
Standing water 48 hours after rain means the fall is wrong or the outlet is blocked. In a freezing winter that water expands inside a lap, lifts it, then thaws and runs in through the gap it made. Re-covering over it buys a couple of seasons.
Parapets, copings and internal outlets on attached buildings. A junction with a pitched roof above on suburban additions. Insulation, which is a real part of the cost and should be stated separately.
On a small rear addition, EPDM at $5 to $9 is usually the right system rather than merely the cheap one. TPO earns its premium on large areas over occupied space, and we will say which applies rather than defaulting upward.
Lodi sits in the middle of this site's range and that makes it unpredictable in a specific way: some houses have proper eaves and gutters, some are effectively attached with a parapet at the boundary, and the two need different repairs. Establishing which you have is the first five minutes of the survey.
Two are about New Jersey specifically, and one catches more than you would expect across eight town lines.
'Repair roof' is not a scope. 'Re-bed the valley, replace two vent boots, re-lap the upstand to the parapet' is -- and it can be checked when the work is finished, which is the entire point.
Membrane and thickness on a flat roof. Gutter size and downspout size on gutters. Shingle grade on a pitch. Those are the lines that separate a cheap quote from a lesser roof, and they are the first things left out.
On most of this housing the truth about where water traveled is visible from underneath and nowhere else. A quote produced from the roof alone has skipped the half that tells you where to work.
Lodi is the least predictable town on this list and it is worth knowing why.
The permit route is straightforward -- Lodi construction office, same state code as everywhere else -- and the variable is the building.
Worth checking whether the unit or the flashing failed before agreeing to anything.
Because the housing here is mixed, an inspection is worth more in Lodi than in a uniform town -- you genuinely cannot infer your roof from your neighbor's.
Maintenance is worth more here precisely because the housing is unpredictable: a regular visit builds a record of what your particular roof does, which on a mixed street is information you cannot get any other way.
Parapets and outlets. No eaves, no gutters, edge failures.
Large and varied. Real eaves, real gutters, real driveways.
Narrow plots, and two roof systems on one building.
Built as a set, so the street is a reliable guide.
Mature trees. Gutter capacity beats gutter material.
Driveways and side access, but hillside staging.
Victorian detail. Never price this on area alone.
What people ask about this work, answered plainly.
More urgent than in a warm climate. Water still sitting 48 hours after rain means the fall is wrong or the outlet is blocked, and in a freezing winter that water expands inside laps and under flashings and lifts them mechanically.
EPDM at $5 to $9 per square foot is the cheaper system and on a small rear addition it is frequently right. TPO at $6 to $12 earns its premium on larger areas and where reflectivity matters. We will say which applies rather than defaulting to the pricier one.
It depends on the building. Replacing a roof covering on a DETACHED one- or two-family dwelling is ordinary maintenance under N.J.A.C. 5:23-2.7 -- no permit, no inspection. An attached house, three or more units, or anything structural is permitted work. We confirm which office and what it needs before the work is booked.
A physical inspection at $150 to $250 for most situations, including buying a house. A drone survey at $200 to $400 where a roof cannot be walked safely -- steep, fragile or very large. Infrared at $400 to $600 only where a flat roof leaks repeatedly with no visible cause, because wet insulation is invisible from above.
Often not. Almost every skylight leak is a flashing leak rather than a glass or seal failure: the unit sits on a curb and the covering has to be dressed up and over it. A fogged, failed unit does need replacing. A sound unit on a badly flashed curb does not, and we will tell you which you have.
The correct construction office confirmed before anything is booked. New Jersey figures, stated per lane rather than as one number.
