Edge metal
New drip edge, coping or gravel stop at the roof edge so the edge stays sealed and tight.
Flat Roofing
TPO Roofing Millburn, NJ
A local roofing contractor in Millburn can put a new TPO membrane on a flat roof, which turns the whole roof into one continuous sheet with no glued laps. Call (973) 858-1841 to reach a local roofer.
A TPO roof is a single sheet of thermoplastic membrane, usually white, laid over rigid insulation on a low-slope deck. 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. Leaks come from under-welded seams, flashing that pulls away at walls and curbs, and penetrations sealed with caulk instead of proper boots. Tapered insulation and crickets that move water to the drains or scuppers keep the membrane from sitting under standing water.
Many tpo roofing calls in Millburn also turn up a need for tpo roof repair or flat roof installation.

How a TPO roof is installed
Here is how a typical TPO roof goes on, from deck to seams.
Survey the old roof
Before anything is ordered, the roofer cuts a small sample through the roof to see what is underneath and probes for wet insulation. Since most codes cap a building at two roof layers, the core cut often settles the tear-off question.
Tear off or recover
On a tear-off, the crew strips everything to the deck and replaces any sections that are soft or rusted. On a recover, a cover board goes over the old roof so the new membrane has a flat, solid base.
Install insulation boards
Polyiso boards go down next, and tapered panels and crickets are added where water needs help getting to drains or scuppers. Many energy codes require a minimum insulation value when a roof is replaced, so this layer is planned to meet it.
Roll out the TPO
The membrane is fastened at the laps or fully adhered, depending on the deck, the wind exposure and the design. The roofer picks the method based on wind exposure, deck type and whether adhesive odors would bother the people inside.
Heat-weld every seam
A robotic hot-air welder runs the long seams and a hand welder does corners and details, fusing the overlapping sheets together. After welding, the roofer drags a probe along the seams to catch cold or skipped spots.
Seal the penetrations
Penetrations get molded boots or field-built flashing, curbs are wrapped and walls are flashed up and capped. At the perimeter, coated edge metal is installed so the membrane welds to it instead of relying on sealant.
What is included
What a TPO roof job includes
Core cut
A check of the old roof for trapped water before the new roof is planned.
Insulation boards
New insulation boards sized for the energy code with slope built toward drains and scuppers.
Welded membrane
White TPO membrane in the chosen thickness so the roof acts as one continuous sheet.
Penetration flashing
Flashing at vents, curbs, skylights and walls built from the same membrane as the field.

TPO Roof Installation Millburn, NJ
New TPO roof installation is the cleanest version of the job, since there is no old roof to deal with. Drain or scupper locations, tapered insulation and the attachment method are worked out up front so the finished roof drains on its own.
Residential TPO installation in Millburn 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 Millburn, NJ
A TPO roof replacement comes into play when repairs stop holding because the sheet or the insulation under it has worn out. 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.
A single dry existing roof can sometimes stay in place under the new membrane. With two existing layers, a full tear-off is required in most places.

PVC Roofing Millburn, NJ
PVC roofing is the close cousin of TPO: a single-ply thermoplastic membrane with heat-welded seams. 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. In Millburn, the choice usually comes down to what the roof is exposed to, with PVC for grease and chemicals and TPO for most other low-slope roofs.

TPO Roofing Near Me
In Millburn, 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. Across Millburn and nearby towns like Vauxhall, Springfield, Short Hills and Union, older roofs often have one or two layers already in place, which is why the core cut and tear-off decision matter so much, so the best time to plan a TPO roof is before the old one starts leaking into the ceiling.

Roofs in this climate
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. Strong coastal storms push rain into every weak spot at the flashing and valleys. That is why roof repair in Millburn is busiest after a hard winter and before the next one.

TPO Roofing questions
How does TPO compare to EPDM rubber roofing?
Each has its strengths. EPDM is black rubber with adhesive or taped seams, and TPO is a white thermoplastic with welded 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.
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.
Does a white TPO roof save energy?
White TPO bounces much of the summer sun back off the roof. 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.
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. It is not meant for steep roofs, where shingles or metal are the better fit. The key on a house is the tie-in where the TPO meets the shingles or siding.
Can TPO go over my existing roof?
A survey of the old roof answers that question. 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.
