Flat Roofing
TPO Roofing Hillside, NJ
A roofer in Hillside 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 (908) 562-6893 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. 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.
Many tpo roofing calls in Hillside also turn up a need for tpo roof repair or flat roof installation.

How a TPO roof is installed
Most TPO jobs follow the same basic order.
Start with the deck
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. Codes generally allow no more than two roof systems, so a roof that already has two must be torn off.
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.
Build in the slope
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.
Heat-weld every seam
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.
Finish the edges
Vent pipes, curbs, drains and walls are each flashed with TPO welded to the field sheet. At the perimeter, coated edge metal is installed so the membrane welds to it instead of relying on sealant.
What is included
What a TPO roof job includes
Moisture check
A sample cut through the old layers to decide between tear-off and recover.
Curb flashing
Flashing at vents, curbs, skylights and walls instead of caulk that dries out.
TPO sheets
White TPO membrane in the chosen thickness so the roof acts as one continuous sheet.
Tapered insulation
Rigid insulation with tapered sections plus a cover board where the design calls for one.

TPO Roof Installation Hillside, NJ
For a brand new low-slope roof, the important decisions come before the first roll is opened. Drain or scupper locations, tapered insulation and the attachment method are worked out up front so the finished roof drains on its own.
On homes in Hillside, 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 Hillside, 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. A moisture scan, often with an infrared camera, shows how much of the insulation is wet and has to come out. Covering wet insulation is a common shortcut that leads to early failure, so it should be removed.
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 Hillside, 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 Hillside, 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 Hillside, 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 Hillside and around Union, Elizabeth, Roselle Park and Vauxhall 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 Hillside
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, 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 Hillside is busiest after a hard winter and before the next one.

Common questions about tpo roofing
How long does a TPO roof last?
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.
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. Many roofers favor TPO where cooling matters and EPDM where a simple, flexible membrane is wanted.
Can TPO be used on a home?
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. 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. A cooler roof surface means less heat moving into the building, which can lower air conditioning demand. Dirt buildup slowly reduces the effect.
Can TPO go over my existing roof?
The core cut decides that. A recover over a single, dry roof is usually possible. With two layers already in place or trapped moisture, a tear-off is the right call.
