TPO sheets
Single-ply TPO rolled out across the roof so the roof acts as one continuous sheet.

TPO Roofing Fanwood, NJ
A roofer in Fanwood 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. Dial (908) 663-5020 to talk through a TPO roof with 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. 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.
Most TPO problems trace back to how the roof was put down rather than the membrane itself. Leaks come from under-welded seams, flashing that pulls away at walls and curbs, and penetrations sealed with caulk instead of proper boots. 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.
Survey the old 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.
Tear off or recover
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.
Build in the slope
Insulation boards are laid in staggered layers, with tapered sections built to move water off flat spots. 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. 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. Each seam is then checked with a seam probe to find any spot that did not fuse.
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
Parts of a TPO roof
Moisture check
A check of the old roof for trapped water before the new roof is planned.
Edge metal
New drip edge, coping or gravel stop at the roof edge with new drain rings where needed.
Penetration flashing
Molded boots on pipes and wrapped curbs under equipment instead of caulk that dries out.
Insulation boards
New insulation boards sized for the energy code so water moves off instead of ponding.

TPO Roof Installation Fanwood, 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.
For Fanwood homeowners, the usual TPO installation is a small roof where shingles cannot work because the pitch is too low. 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 Fanwood, 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. Covering wet insulation is a common shortcut that leads to early failure, so it should be removed.
A single dry existing roof can sometimes stay in place under the new membrane. A second recover is off the table on a roof that already carries two systems.

PVC Roofing Fanwood, NJ
PVC membrane looks and installs much like TPO, with the same hot-air welded seams and many of the same flashing details. Where it stands apart is resistance to grease and chemicals, making it a frequent choice under restaurant exhaust fans and on some industrial roofs.
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 most Fanwood 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
Around Fanwood, TPO goes on everything from shopping centers to the flat roof over a back porch: older flat roofs that have been patched for years are the most common candidates. Homes and buildings in Fanwood and around Westfield, Plainfield, Watchung and Mountainside see summer heat, heavy rain and the occasional strong storm, all of which test a flat roof at its seams and drains, so the best time to plan a TPO roof is before the old one starts leaking into the ceiling.

How the weather here affects roofs around Fanwood
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. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. That is why roof repair in Fanwood is busiest after a hard winter and before the next one.

Common questions about tpo roofing
What is the lifespan of a TPO roof?
A well-installed TPO roof commonly lasts somewhere around 15 to 30 years. 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?
The core cut decides that. TPO can go over one existing roof that is dry and sound, with a cover board between the two. With two layers already in place or trapped moisture, a tear-off is the right call.
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. Keeping the surface reasonably clean helps it stay reflective.
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. Most residential TPO leaks start at the wall or shingle tie-in, so that detail matters most.
How does TPO compare to EPDM rubber roofing?
Both are proven flat roof membranes with different trade-offs. 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.
