TPO Roofing Pequannock, NJ
A roofer in Pequannock can install a TPO roof on a flat or low-slope section of a home or building, after checking the deck, the insulation and how water drains off. Call (862) 458-0110 to reach a local roofer.
TPO, short for thermoplastic polyolefin, is a single-ply roofing membrane made for roofs that are flat or close to it. Rolls come in several widths and thicknesses, with 60 mil a common middle choice and 80 mil used where the roof sees more wear. 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. Tapered insulation and crickets that move water to the drains or scuppers keep the membrane from sitting under standing water.
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.
Survey the old roof
The roofer walks the roof, checks for soft decking and often takes a core cut to see how many layers are there and whether the insulation is wet. Wet insulation or a second existing layer both point toward a full tear-off rather than a recover.
Get down to a sound base
Old roofing is removed where needed, damaged decking is replaced and the surface is cleaned and made smooth. For a recover over one sound layer, a cover board separates the new membrane from the old surface.
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.
Roll out the TPO
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.
Fuse the laps
Seams are welded with hot air, using a walking welder on long runs and a hand gun with a roller at corners. Each seam is then checked with a seam probe to find any spot that did not fuse.
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
Parts of a TPO roof
Moisture check
A check of the old roof for trapped water before the new roof is planned.
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 so leaks do not start at the details.
Tapered insulation
Polyiso insulation laid to code thickness so water moves off instead of ponding.

TPO Roof Installation Pequannock, 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.
For Pequannock homeowners, the usual TPO installation is a small roof where shingles cannot work because the pitch is too low. Shingles need a minimum pitch to shed water, so these low sections need a membrane. 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 Pequannock, NJ
TPO roof replacement means taking an aging membrane or old flat roof down to a sound base and putting a new TPO system on top. An infrared or capacitance scan helps map wet areas so only the damaged insulation is replaced. Leaving wet boards under a new roof traps the water and causes blisters and rot later.
If the existing roof is one layer and mostly dry, a recover with a new cover board and TPO can be an option. With two existing layers, a full tear-off is required in most places.

PVC Roofing Pequannock, 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.
PVC and TPO cannot be welded to each other, so repairs and additions have to match the existing membrane. In Pequannock, 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
TPO roofs in Pequannock show up on more than warehouses: older homes with flat sections and newer buildings with long, low roofs both end up with it. Across Pequannock and nearby towns like Pompton Plains, Lincoln Park, Towaco and Riverdale, 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. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder 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 Pequannock, NJ have the roof checked in the fall and again after the snow melts.

TPO Roofing FAQ
Do I have to tear off my old flat roof for TPO?
A survey of the old roof answers that question. TPO can go over one existing roof that is dry and sound, with a cover board between the two. Two existing layers or wet insulation mean a tear-off.
Is a TPO roof good for a house?
On homes, TPO is a strong choice wherever the pitch is too low for shingles. For the steep parts of the roof, shingles or metal remain the norm. Most residential TPO leaks start at the wall or shingle tie-in, so that detail matters most.
Why are TPO roofs white?
A white membrane reflects sunlight, which keeps the roof surface much cooler than a dark one. A cooler roof surface means less heat moving into the building, which can lower air conditioning demand. Dirt buildup slowly reduces the effect.
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.
Is TPO better than EPDM?
The two membranes suit different roofs. TPO is white and reflective with heat-welded seams, while EPDM is a black rubber sheet whose seams are joined with tape or adhesive. 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.
