Edge metal
Perimeter metal the membrane can weld to so the edge stays sealed and tight.
Flat Roofing
TPO Roofing Closter, NJ
A roofer in Closter can install a TPO roof on a flat or low-slope section of a home or building, giving a reflective, watertight surface that stays cooler than old tar or rolled roofing. Dial (551) 395-0646 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. 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. 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. 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. Drainage matters just as much, since water that sits in low spots for days speeds up wear and finds any weak seam.
If the problem goes deeper than it first looked, a Closter roofer may also recommend 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.
Check the existing roof
A survey of the old roof usually includes a small core cut through the layers to check for trapped moisture and count existing roofs. Codes generally allow no more than two roof systems, so a roof that already has two must be torn off.
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. 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 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.
Fuse the laps
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
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 goes into a TPO roof
Tapered insulation
Rigid insulation with tapered sections with slope built toward drains and scuppers.
Curb flashing
Molded boots on pipes and wrapped curbs under equipment built from the same membrane as the field.
TPO sheets
Single-ply TPO rolled out across the roof with every seam hot-air welded and probed.
Moisture check
A core cut or moisture scan of the existing roof so wet insulation does not get buried.

TPO Roof Installation Closter, 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 Closter, TPO installation often covers a flat roof over a porch, a garage, a sunroom or the low section of a split-level roof. Shingle makers set a minimum slope, and below it a membrane is the right choice. 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 Closter, 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.
Recovering over one sound roof avoids hauling the old one away, when the code and the moisture survey allow it. A second recover is off the table on a roof that already carries two systems.

PVC Roofing Closter, NJ
PVC roofing is the close cousin of TPO: a single-ply thermoplastic membrane with heat-welded seams. Where it stands apart is resistance to grease and chemicals, making it a frequent choice under restaurant exhaust fans and on some industrial roofs.
The two membranes look alike but do not weld together, which matters when a roof is being repaired or extended. For most Closter homes and offices, TPO does the job, and PVC is worth considering over kitchens, labs or anywhere oils land on the roof.

TPO Roofing Near Me
In Closter, 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. Across Closter and nearby towns like Demarest, Norwood, Harrington Park and Haworth, 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 it pays to plan the drainage and the details as carefully as the membrane itself.

Roofs in this climate
Cold winters bring snow, ice and a long stretch of freezing nights. When warm attic air melts the snow, the meltwater runs down and freezes again at the eaves, which is how ice dams form and back water up under the shingles. Strong coastal storms push rain into every weak spot at the flashing and valleys. Most homeowners in Closter, NJ have the roof checked in the fall and again after the snow melts.

TPO Roofing questions
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. Dirt buildup slowly reduces the effect.
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.
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.
How does TPO compare to EPDM rubber roofing?
Each has its strengths. TPO is white and reflective with heat-welded seams, while EPDM is a black rubber sheet whose seams are joined with tape or adhesive. Welded seams give TPO an edge at the laps, and EPDM is valued for its flexibility and simple repairs.
Is a TPO roof good for a house?
On homes, TPO is a strong choice wherever the pitch is too low for shingles. 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.
