Tapered insulation
Rigid insulation with tapered sections with slope built toward drains and scuppers.
TPO roofing in Lodi is a white single-ply membrane rolled over insulation and heat-welded at every seam, which turns the whole roof into one continuous sheet with no glued laps. Dial (551) 394-0610 to talk through a TPO roof with 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. 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. Its seams are welded with hot air, so the overlap becomes part of the sheet rather than a glued joint that can let go.
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.

Call nowA TPO roof is built in layers, and each one has a job.
Before anything is ordered, the roofer cuts a small sample through the roof to see what is underneath and probes for wet insulation. Codes generally allow no more than two roof systems, so a roof that already has two must be torn off.
Old roofing is removed where needed, damaged decking is replaced and the surface is cleaned and made smooth. For a recover over one sound layer, a cover board separates the new membrane from the old surface.
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.
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. Fully adhered roofs tend to be quieter in wind and look smoother, while fastened roofs go down faster.
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.
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.
Rigid insulation with tapered sections with slope built toward drains and scuppers.
Coated metal at the perimeter and around drains to hold the sheet down in wind.
A check of the old roof for trapped water so wet insulation does not get buried.
Single-ply TPO rolled out across the roof so the roof acts as one continuous sheet.
TPO flashing welded around every opening so leaks do not start at the details.
For a brand new low-slope roof, the important decisions come before the first roll is opened. The deck, the drain locations and the insulation thickness are set first, then the attachment method is chosen to suit the wind exposure.
Residential TPO installation in Lodi tends to mean smaller roofs: additions, carports, dormers with little pitch and flat sections behind a parapet. 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 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. Wet insulation left in place loses its value and can rust fasteners and steel decking from below.
A single dry existing roof can sometimes stay in place under the new membrane. Once a building already has two roof systems, the next roof has to start from the deck.
Like TPO, a PVC roof is a white or light-colored single-ply sheet whose seams are welded with hot air. PVC handles fats, oils and some chemicals that can soften other membranes, so it often goes on restaurants and food plants.
The two membranes look alike but do not weld together, which matters when a roof is being repaired or extended. In Lodi, 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.
Around Lodi, 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 Lodi and around Hasbrouck Heights, Garfield, Maywood and Hackensack see summer heat, heavy rain and the occasional strong storm, all of which test a flat roof at its seams and drains, 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. When warm attic air melts the snow, the meltwater runs down and freezes again at the 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. Most homeowners in Lodi, NJ have the roof checked in the fall and again after the snow melts.
Small roof problems caught early usually stay small repairs.
Roofers in Lodi know the roof types and weather wear common in local homes.
Ask the roofer about the cause, the options and the estimate before work starts.
