Flat Roofing
TPO Roofing Paramus, NJ
A local roofing contractor in Paramus can put a new TPO membrane on a flat roof, giving a reflective, watertight surface that stays cooler than old tar or rolled roofing. Call (551) 383-2304 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. 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. What sets TPO apart is the seam: hot air melts the overlapping edges so they fuse into one piece instead of relying on glue or tape.
The membrane is only as good as the details around it. 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 Paramus 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.
Start with the deck
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.
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.
Lay the insulation
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.
Secure the sheets
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.
Weld the seams
A robotic hot-air welder runs the long seams and a hand welder does corners and details, fusing the overlapping sheets together. The finished seams are probed by hand so any gap is rewelded before the job is done.
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. TPO-coated edge metal at the perimeter lets the membrane weld right to the edge.
What is included
What a TPO roof job includes
Edge metal
Coated metal at the perimeter and around drains to hold the sheet down in wind.
Curb flashing
Molded boots on pipes and wrapped curbs under equipment so leaks do not start at the details.
Moisture check
A sample cut through the old layers to decide between tear-off and recover.
TPO sheets
Single-ply TPO rolled out across the roof with every seam hot-air welded and probed.

TPO Roof Installation Paramus, 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 Paramus 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 Paramus, 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. Leaving wet boards under a new roof traps the water and causes blisters and rot later.
A single dry existing roof can sometimes stay in place under the new membrane. Once a building already has two roof systems, the next roof has to start from the deck.

PVC Roofing Paramus, 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.
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 a Paramus 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 Paramus, a lot of TPO work replaces old tar and gravel or rolled roofing: low-slope additions, porches, garages and row homes use it as often as offices and stores do. Homes and buildings in Paramus and around Oradell, River Edge, Fair Lawn and New Milford 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.

What the local climate does to a roof
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, 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 Paramus is busiest after a hard winter and before the next one.

Common questions about tpo roofing
Can TPO go over my existing roof?
The core cut decides that. A recover over a single, dry roof is usually possible. Two existing layers or wet insulation mean a tear-off.
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.
Can TPO be used on a home?
Many homes use TPO on flat or nearly flat sections where shingles would leak. It is not meant for steep roofs, where shingles or metal are the better fit. Careful flashing at walls and shingle transitions is what makes it last on a home.
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. A clean surface reflects best.
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. Welded seams give TPO an edge at the laps, and EPDM is valued for its flexibility and simple repairs.
