TPO Roofing South Orange, NJ
TPO roofing in South Orange is a white single-ply membrane rolled over insulation and heat-welded at every seam, after checking the deck, the insulation and how water drains off. One call to (973) 858-1859 reaches a nearby TPO roofer.
On flat and low-slope roofs, TPO has become one of the most common membranes, a single layer of thermoplastic sheet rather than layers of asphalt. Rolls come in several widths and thicknesses, with 60 mil a common middle choice and 80 mil used where the roof sees more wear. Its seams are welded with hot air, so the overlap becomes part of the sheet rather than a glued joint that can let go.
Most TPO problems trace back to how the roof was put down rather than the membrane itself. A seam welded too cold, a corner patch skipped at a curb or edge metal that was never sealed will leak long before the sheet wears out. Water that ponds for more than a couple of days after rain wears the surface and pushes into any weak spot, so slope to the drains is part of the design.
Many tpo roofing calls in South Orange also turn up a need for tpo roof repair or flat roof installation.

What a TPO roof job involves
Most TPO jobs follow the same basic order.
Start with the deck
A survey of the old roof usually includes a small core cut through the layers to check for trapped moisture and count existing roofs. Codes generally allow no more than two roof systems, so a roof that already has two must be torn off.
Prepare the substrate
If the old roof is coming off, it is stripped to the deck, and rotted plywood or rusted steel deck is replaced. On a recover, a cover board goes over the old roof so the new membrane has a flat, solid base.
Install insulation boards
Rigid insulation, usually polyiso, is fastened or adhered over the deck, often in tapered boards that pitch water toward the drains. The insulation thickness is set partly by the local energy code, which often calls for more than the old roof had.
Secure the sheets
Each sheet is either screwed down along its edge, with the next sheet lapping over the fasteners, or glued to the insulation across its whole back. Fully adhered roofs tend to be quieter in wind and look smoother, while fastened roofs go down faster.
Weld the seams
Every lap is heat-welded, with an automatic welder on straight runs and hand welding around details. Each seam is then checked with a seam probe to find any spot that did not fuse.
Finish the edges
Penetrations get molded boots or field-built flashing, curbs are wrapped and walls are flashed up and capped. Drains get new clamping rings, and the roof edge gets metal the membrane can be welded to.
What is included
Parts of a TPO roof
TPO sheets
TPO sheets fastened or adhered to the insulation joined with welded seams instead of glue.
Penetration flashing
TPO flashing welded around every opening built from the same membrane as the field.
Core cut
A core cut or moisture scan of the existing roof so wet insulation does not get buried.
Tapered insulation
Polyiso insulation laid to code thickness with slope built toward drains and scuppers.

TPO Roof Installation South Orange, NJ
New TPO roof installation is the cleanest version of the job, since there is no old roof to deal with. The roofer confirms the deck type, plans tapered insulation so water reaches the drains or a gutter edge, and chooses between fastened and adhered membrane.
Residential TPO installation in South Orange tends to mean smaller roofs: additions, carports, dormers with little pitch and flat sections behind a parapet. Shingle makers set a minimum slope, and below it a membrane is the right choice. Where the TPO meets a shingled slope, the transition is flashed so water from above runs over the membrane, not under it.

TPO Roof Replacement South Orange, NJ
TPO roof replacement means taking an aging membrane or old flat roof down to a sound base and putting a new TPO system on top. Moisture surveys and core cuts show whether the roof can be recovered or needs a full tear-off. Covering wet insulation is a common shortcut that leads to early failure, so it should be removed.
If the existing roof is one layer and mostly dry, a recover with a new cover board and TPO can be an option. A second recover is off the table on a roof that already carries two systems.

PVC Roofing South Orange, NJ
PVC membrane looks and installs much like TPO, with the same hot-air welded seams and many of the same flashing details. The difference is in the chemistry: PVC holds up better to grease, oils and many chemicals, which is why it is a common pick for restaurants and buildings with kitchen exhaust on the roof.
The two membranes look alike but do not weld together, which matters when a roof is being repaired or extended. For a South Orange roof with no grease or chemical exposure, TPO is often the simpler choice, while PVC earns its place where those exposures exist.

TPO Roofing Near Me
In South Orange, a lot of TPO work replaces old tar and gravel or rolled roofing: older flat roofs that have been patched for years are the most common candidates. Homes and buildings in South Orange and around Vauxhall, East Orange, Union and Short Hills see summer heat, heavy rain and the occasional strong storm, all of which test a flat roof at its seams and drains, and a well-welded, well-drained TPO roof handles that better than a patched old surface.
For tpo roofing in South Orange, NJ or nearby towns like Vauxhall, East Orange, Union and Short Hills, call (973) 858-1859 to reach a roofer who covers your street.
How the weather here affects roofs around South Orange
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder eaves, building ice dams that push water up under the shingles. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. That is why roof repair in South Orange is busiest after a hard winter and before the next one.

TPO Roofing questions
Is a TPO roof good for a house?
TPO works well on the low-slope parts of a house, such as porches, additions, garages and flat sections behind parapets. Steeper slopes are still better served by shingles or metal. Careful flashing at walls and shingle transitions is what makes it last on a home.
What is the lifespan of a TPO roof?
Most TPO roofs last roughly 15 to 30 years when they are installed and maintained well. An 80 mil sheet on a roof that drains well and sees little traffic tends to outlast a thin sheet on a roof that ponds.
How does TPO compare to EPDM rubber roofing?
The two membranes suit different roofs. TPO reflects sun and its seams are welded, while EPDM rubber stays flexible in cold and has taped or glued seams. In hot, sunny areas and on roofs with many seams, TPO is often preferred, while EPDM has a long track record and is easy to patch.
Can TPO go over my existing roof?
The core cut decides that. A recover over a single, dry roof is usually possible. If there are already two roofs, or the insulation is wet, the old roofing comes off down to the deck.
Why are TPO roofs white?
The white surface reflects a large share of the sun instead of absorbing it. A cooler roof surface means less heat moving into the building, which can lower air conditioning demand. Dirt buildup slowly reduces the effect.
