TPO sheets
White TPO membrane in the chosen thickness so the roof acts as one continuous sheet.

TPO Roofing Orange, NJ
A local roofing contractor in Orange can put a new TPO membrane on a flat roof, after checking the deck, the insulation and how water drains off. One call to (973) 858-1825 reaches a nearby TPO roofer.
A TPO roof is a single sheet of thermoplastic membrane, usually white, laid over rigid insulation on a low-slope deck. The sheets come in rolls several feet wide and in common thicknesses of 45, 60 or 80 mil, with thicker membrane lasting longer under sun and traffic. 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. Tapered insulation and crickets that move water to the drains or scuppers keep the membrane from sitting under standing water.
If the problem goes deeper than it first looked, an Orange roofer may also recommend tpo roof repair or flat roof installation.

What a TPO roof job involves
A TPO roof is built in layers, and each one has a job.
Check the existing roof
The roofer walks the roof, checks for soft decking and often takes a core cut to see how many layers are there and whether the insulation is wet. Wet insulation or a second existing layer both point toward a full tear-off rather than a recover.
Get down to a sound base
On a tear-off, the crew strips everything to the deck and replaces any sections that are soft or rusted. For a recover over one sound layer, a cover board separates the new membrane from the old surface.
Build in the slope
Polyiso boards go down next, and tapered panels and crickets are added where water needs help getting to drains or scuppers. This layer also brings the roof up to the insulation level current codes expect.
Roll out the TPO
The TPO sheets are rolled out and either mechanically fastened with plates and screws hidden in the seam laps or fully adhered with membrane adhesive. Adhered sheets resist flutter in high winds, and fastened systems suit large open roofs.
Weld the seams
Every lap is heat-welded, with an automatic welder on straight runs and hand welding around details. The finished seams are probed by hand so any gap is rewelded before the job is done.
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
What a TPO roof job includes
Insulation boards
Rigid insulation with tapered sections plus a cover board where the design calls for one.
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 to decide between tear-off and recover.
Edge metal
Perimeter metal the membrane can weld to so the edge stays sealed and tight.

TPO Roof Installation Orange, NJ
A TPO roof installation on new construction or an addition starts with the deck and the slope, not the membrane. The deck, the drain locations and the insulation thickness are set first, then the attachment method is chosen to suit the wind exposure.
Residential TPO installation in Orange tends to mean smaller roofs: additions, carports, dormers with little pitch and flat sections behind a parapet. Below the minimum pitch for shingles, a welded membrane is far more reliable. The tricky part is the tie-in to the shingled roof, which has to be lapped so water flows over the TPO.

TPO Roof Replacement Orange, NJ
A TPO roof replacement comes into play when repairs stop holding because the sheet or the insulation under it has worn out. A moisture scan, often with an infrared camera, shows how much of the insulation is wet and has to come out. Covering wet insulation is a common shortcut that leads to early failure, so it should be removed.
Recovering over one sound roof avoids hauling the old one away, when the code and the moisture survey allow it. Once a building already has two roof systems, the next roof has to start from the deck.

PVC Roofing Orange, NJ
PVC roofing is the close cousin of TPO: a single-ply thermoplastic membrane with heat-welded seams. PVC handles fats, oils and some chemicals that can soften other membranes, so it often goes on restaurants and food plants.
A roofer needs to know whether a white roof is PVC or TPO before patching it, since the two do not weld to each other. For an 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
Around Orange, TPO goes on everything from shopping centers to the flat roof over a back porch: older homes with flat sections and newer buildings with long, low roofs both end up with it. Homes and buildings in Orange and around East Orange, Glen Ridge, Caldwell and Roseland 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.

How the weather here affects roofs around Orange
Cold winters bring snow, ice and a long stretch of freezing nights. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder eaves, which is how ice dams form and back 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 Orange is busiest after a hard winter and before the next one.

TPO Roofing FAQ
What is the lifespan of a TPO roof?
A well-installed TPO roof commonly lasts somewhere around 15 to 30 years. Thicker membrane, good drainage and limited foot traffic push it toward the long end.
Is a TPO roof good for a house?
On homes, TPO is a strong choice wherever the pitch is too low for shingles. Steeper slopes are still better served by shingles or metal. Most residential TPO leaks start at the wall or shingle tie-in, so that detail matters most.
Does a white TPO roof save energy?
A white membrane reflects sunlight, which keeps the roof surface much cooler than a dark one. Less heat soaks through to the building, so the space under it can stay cooler in summer. Keeping the surface reasonably clean helps it stay reflective.
How does TPO compare to EPDM rubber roofing?
Each has its strengths. 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?
A survey of the old roof answers that question. If there is only one existing roof and the insulation is dry, a recover with a cover board is often allowed. Two existing layers or wet insulation mean a tear-off.
