Curb flashing
Flashing at vents, curbs, skylights and walls built from the same membrane as the field.
A roofer in Boonton 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 (862) 420-3040 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.
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. 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.
If the problem goes deeper than it first looked, a Boonton roofer may also recommend tpo roof repair or flat roof installation.

Call nowHere is how a typical TPO roof goes on, from deck to seams.
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.
If the old roof is coming off, it is stripped to the deck, and rotted plywood or rusted steel deck is replaced. Where the old roof stays, a recovery board goes down first so the TPO does not ride on gravel or blisters.
Rigid insulation, usually polyiso, is fastened or adhered over the deck, often in tapered boards that pitch water toward the drains. This layer also brings the roof up to the insulation level current codes expect.
Each sheet is either screwed down along its edge, with the next sheet lapping over the fasteners, or glued to the insulation across its whole back. Adhered sheets resist flutter in high winds, and fastened systems suit large open roofs.
A robotic hot-air welder runs the long seams and a hand welder does corners and details, fusing the overlapping sheets together. The finished seams are probed by hand so any gap is rewelded before the job is done.
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. TPO-coated edge metal at the perimeter lets the membrane weld right to the edge.

A core cut or moisture scan of the existing roof before the new roof is planned.
TPO sheets fastened or adhered to the insulation so the roof acts as one continuous sheet.
Perimeter metal the membrane can weld to to hold the sheet down in wind.
Polyiso insulation laid to code thickness so water moves off instead of ponding.
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 Boonton, TPO installation often covers a flat roof over a porch, a garage, a sunroom or the low section of a split-level roof. 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.
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.
A single dry existing roof can sometimes stay in place under the new membrane. With two existing layers, a full tear-off is required in most places.
PVC membrane looks and installs much like TPO, with the same hot-air welded seams and many of the same flashing details. The difference is in the chemistry: PVC holds up better to grease, oils and many chemicals, which is why it is a common pick for restaurants and buildings with kitchen exhaust on the roof.
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 Boonton, 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.
In Boonton, a lot of TPO work replaces old tar and gravel or rolled roofing: older homes with flat sections and newer buildings with long, low roofs both end up with it. Across Boonton and nearby towns like Lake Hiawatha, Mountain Lakes, Parsippany and Towaco, 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.

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, 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. That is why roof repair in Boonton is busiest after a hard winter and before the next one.
Small roof problems caught early usually stay small repairs.
Roofers in Boonton know the roof types and weather wear common in local homes.
