Insulation boards
Rigid insulation with tapered sections so water moves off instead of ponding.

TPO Roofing Leonia, NJ
TPO roofing in Leonia is a white single-ply membrane rolled over insulation and heat-welded at every seam, giving a reflective, watertight surface that stays cooler than old tar or rolled roofing. One call to (551) 348-8956 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. The laps are fused with a hot-air welder, which is the main reason a well-installed TPO roof stays tight at the seams for years.
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.
Many tpo roofing calls in Leonia also turn up a need for 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
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
Old roofing is removed where needed, damaged decking is replaced and the surface is cleaned and made smooth. Where the old roof stays, a recovery board goes down first so the TPO does not ride on gravel or blisters.
Install insulation boards
Polyiso boards go down next, and tapered panels and crickets are added where water needs help getting to drains or scuppers. The insulation thickness is set partly by the local energy code, which often calls for more than the old roof had.
Attach the membrane
The membrane is fastened at the laps or fully adhered, depending on the deck, the wind exposure and the design. Adhered sheets resist flutter in high winds, and fastened systems suit large open roofs.
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.
Flash every detail
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
Perimeter metal the membrane can weld to so the edge stays sealed and tight.
Penetration flashing
Molded boots on pipes and wrapped curbs under equipment so leaks do not start at the details.
TPO sheets
White TPO membrane in the chosen thickness joined with welded seams instead of glue.
Core cut
A sample cut through the old layers before the new roof is planned.

TPO Roof Installation Leonia, 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.
On homes in Leonia, 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 tie-in where the shingles end and the membrane begins deserves extra attention, since that joint is where many small flat roofs leak.

TPO Roof Replacement Leonia, 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. A moisture scan, often with an infrared camera, shows how much of the insulation is wet and has to come out. 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. A second recover is off the table on a roof that already carries two systems.

PVC Roofing Leonia, NJ
Like TPO, a PVC roof is a white or light-colored single-ply sheet whose seams are welded with hot air. PVC handles fats, oils and some chemicals that can soften other membranes, so it often goes on restaurants and food plants.
The two membranes look alike but do not weld together, which matters when a roof is being repaired or extended. In Leonia, 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
Around Leonia, 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. Across Leonia and nearby towns like Palisades Park, Fort Lee, Ridgefield Park and Englewood, older roofs often have one or two layers already in place, which is why the core cut and tear-off decision matter so much, and a well-welded, well-drained TPO roof handles that better than a patched old surface.

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 Leonia is busiest after a hard winter and before the next one.

Common questions about tpo roofing
Can TPO be used on a home?
Many homes use TPO on flat or nearly flat sections where shingles would leak. For the steep parts of the roof, shingles or metal remain the norm. The key on a house is the tie-in where the TPO meets the shingles or siding.
Why are TPO roofs white?
White TPO bounces much of the summer sun back off the roof. A cooler roof surface means less heat moving into the building, which can lower air conditioning demand. 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. With two layers already in place or trapped moisture, a tear-off is the right call.
How long does a TPO roof last?
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. 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.
