Tapered insulation
Rigid insulation with tapered sections so water moves off instead of ponding.
Flat Roofing
TPO Roofing Kenilworth, NJ
A roofer in Kenilworth can install a TPO roof on a flat or low-slope section of a home or building, which turns the whole roof into one continuous sheet with no glued laps. Call (908) 613-5001 to reach a local 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. 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.
TPO Roofing is often paired with tpo roof repair and flat roof installation, depending on the cause.

What a TPO roof job involves
A TPO roof is built in layers, and each one has a job.
Survey the old 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. Wet insulation or a second existing layer both point toward a full tear-off rather than a recover.
Get down to a sound base
On a tear-off, the crew strips everything to the deck and replaces any sections that are soft or rusted. 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. 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 TPO sheets are rolled out and either mechanically fastened with plates and screws hidden in the seam laps or fully adhered with membrane adhesive. The roofer picks the method based on wind exposure, deck type and whether adhesive odors would bother the people inside.
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. Each seam is then checked with a seam probe to find any spot that did not fuse.
Flash every detail
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
Curb flashing
Molded boots on pipes and wrapped curbs under equipment built from the same membrane as the field.
Core cut
A core cut or moisture scan of the existing roof before the new roof is planned.
Edge metal
Coated metal at the perimeter and around drains with new drain rings where needed.
Welded membrane
TPO sheets fastened or adhered to the insulation so the roof acts as one continuous sheet.

TPO Roof Installation Kenilworth, NJ
New TPO roof installation is the cleanest version of the job, since there is no old roof to deal with. Drain or scupper locations, tapered insulation and the attachment method are worked out up front so the finished roof drains on its own.
Residential TPO installation in Kenilworth tends to mean smaller roofs: additions, carports, dormers with little pitch and flat sections behind a parapet. Shingles need a minimum pitch to shed water, so these low sections need a membrane. 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 Kenilworth, 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.
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 Kenilworth, NJ
PVC membrane looks and installs much like TPO, with the same hot-air welded seams and many of the same flashing details. PVC handles fats, oils and some chemicals that can soften other membranes, so it often goes on restaurants and food plants.
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. In Kenilworth, 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
In Kenilworth, 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 Kenilworth and around Roselle Park, Union, Cranford and Roselle 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
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. When warm attic air melts the snow, the meltwater runs down and freezes again at the 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 Kenilworth is busiest after a hard winter and before the next one.

TPO Roofing questions
How does TPO compare to EPDM rubber roofing?
Both are proven flat roof membranes with different trade-offs. TPO reflects sun and its seams are welded, while EPDM rubber stays flexible in cold and has taped or glued 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.
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?
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. Keeping the surface reasonably clean helps it stay reflective.
How long does a TPO roof last?
Expect something in the range of 15 to 30 years from a good TPO roof. 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. 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.
