Moisture check
A check of the old roof for trapped water so wet insulation does not get buried.
A local roofing contractor in Maplewood can put a new TPO membrane on a flat roof, which turns the whole roof into one continuous sheet with no glued laps. One call to (973) 858-1830 reaches a nearby TPO 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.
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. 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.

A survey of the old roof usually includes a small core cut through the layers to check for trapped moisture and count existing roofs. Since most codes cap a building at two roof layers, the core cut often settles the tear-off question.
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.
Polyiso boards go down next, and tapered panels and crickets are added where water needs help getting to drains or scuppers. This layer also brings the roof up to the insulation level current codes expect.
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.
Seams are welded with hot air, using a walking welder on long runs and a hand gun with a roller at corners. After welding, the roofer drags a probe along the seams to catch cold or skipped spots.
Penetrations get molded boots or field-built flashing, curbs are wrapped and walls are flashed up and capped. Drains get new clamping rings, and the roof edge gets metal the membrane can be welded to.

TPO flashing welded around every opening built from the same membrane as the field.
Rigid insulation with tapered sections with slope built toward drains and scuppers.
Perimeter metal the membrane can weld to to hold the sheet down in wind.
White TPO membrane in the chosen thickness with every seam hot-air welded and probed.
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 Maplewood homeowners, the usual TPO installation is a small roof where shingles cannot work because the pitch is too low. Below the minimum pitch for shingles, a welded membrane is far more reliable. 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. A moisture scan, often with an infrared camera, shows how much of the insulation is wet and has to come out. Wet insulation left in place loses its value and can rust fasteners and steel decking from below.
If the existing roof is one layer and mostly dry, a recover with a new cover board and TPO can be an option. A second recover is off the table on a roof that already carries two systems.
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.
The two membranes look alike but do not weld together, which matters when a roof is being repaired or extended. In Maplewood, 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 roofs in Maplewood show up on more than warehouses: older flat roofs that have been patched for years are the most common candidates. From Maplewood out to Vauxhall, Union, Springfield and Short Hills, the mix of older low-slope sections and newer commercial roofs means every job starts with a look at what is already there, and a well-welded, well-drained TPO roof handles that better than a patched old surface.

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. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. Most homeowners in Maplewood, NJ have the roof checked in the fall and again after the snow melts.
A roof problem fixed early rarely spreads to the decking, the insulation or the ceilings.
