TPO Roofing Newton, NJ
TPO roofing in Newton is a white single-ply membrane rolled over insulation and heat-welded at every seam, which turns the whole roof into one continuous sheet with no glued laps. Dial (973) 858-9950 to talk through a TPO roof with a local roofer.
TPO, short for thermoplastic polyolefin, is a single-ply roofing membrane made for roofs that are flat or close to it. It comes in wide rolls in thicknesses like 45, 60 and 80 mil, and the thicker sheets hold up better to foot traffic and weather. Its seams are welded with hot air, so the overlap becomes part of the sheet rather than a glued joint that can let go.
A TPO roof rarely fails in the middle of a sheet; it fails at the edges, seams and penetrations. Cold welds, wrinkles at the laps, unsealed edge metal and loose flashing around vents are where leaks start. 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.
TPO Roofing is often paired with tpo roof repair and flat roof installation, depending on the cause.

The TPO installation process
Here is how a typical TPO roof goes on, from deck to seams.
Check the existing roof
Before anything is ordered, the roofer cuts a small sample through the roof to see what is underneath and probes for wet insulation. Wet insulation or a second existing layer both point toward a full tear-off rather than a recover.
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
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
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. The roofer picks the method based on wind exposure, deck type and whether adhesive odors would bother the people inside.
Fuse the laps
Every lap is heat-welded, with an automatic welder on straight runs and hand welding around details. After welding, the roofer drags a probe along the seams to catch cold or skipped spots.
Finish the edges
Pipes get pre-molded TPO boots, curbs under rooftop units are wrapped with membrane, and walls get flashing run up and held with a termination bar. 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
Perimeter metal
Coated metal at the perimeter and around drains with new drain rings where needed.
Welded membrane
White TPO membrane in the chosen thickness with every seam hot-air welded and probed.
Tapered insulation
New insulation boards sized for the energy code with slope built toward drains and scuppers.
Core cut
A core cut or moisture scan of the existing roof to decide between tear-off and recover.

TPO Roof Installation Newton, NJ
A TPO roof installation on new construction or an addition starts with the deck and the slope, not the membrane. Drain or scupper locations, tapered insulation and the attachment method are worked out up front so the finished roof drains on its own.
On homes in Newton, TPO installation often covers a flat roof over a porch, a garage, a sunroom or the low section of a split-level roof. 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 Newton, NJ
Replacing a TPO roof is usually done when seams have opened in many places, the membrane is cracking or the insulation below is wet. Moisture surveys and core cuts show whether the roof can be recovered or needs a full tear-off. Wet insulation left in place loses its value and can rust fasteners and steel decking from below.
If the existing roof is one layer and mostly dry, a recover with a new cover board and TPO can be an option. Once a building already has two roof systems, the next roof has to start from the deck.

PVC Roofing Newton, NJ
PVC membrane looks and installs much like TPO, with the same hot-air welded seams and many of the same flashing details. PVC handles fats, oils and some chemicals that can soften other membranes, so it often goes on restaurants and food plants.
PVC and TPO cannot be welded to each other, so repairs and additions have to match the existing membrane. For a Newton 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 Newton, 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. From Newton out to Andover, Hopatcong, Allamuchy and Franklin, the mix of older low-slope sections and newer commercial roofs means every job starts with a look at what is already there, and a well-welded, well-drained TPO roof handles that better than a patched old surface.

What the local climate does to a roof
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. When warm attic air melts the snow, the meltwater runs down and freezes again at the 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. Most homeowners in Newton, NJ have the roof checked in the fall and again after the snow melts.

Common questions about tpo roofing
How long does a TPO roof last?
Most TPO roofs last roughly 15 to 30 years when they are installed and maintained well. Thicker membrane, good drainage and limited foot traffic push it toward the long end.
Why are TPO roofs white?
The white surface reflects a large share of the sun instead of absorbing it. Less heat soaks through to the building, so the space under it can stay cooler in summer. A clean surface reflects best.
Can TPO go over my existing roof?
The core cut decides that. 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.
Can TPO be used on a home?
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. The key on a house is the tie-in where the TPO meets the shingles or siding.
Is TPO better than EPDM?
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. Welded seams give TPO an edge at the laps, and EPDM is valued for its flexibility and simple repairs.
