Tapered insulation
New insulation boards sized for the energy code plus a cover board where the design calls for one.
A roofer in Garfield 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 (551) 348-2856 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.
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.
Many tpo roofing calls in Garfield also turn up a need for tpo roof repair or flat roof installation.

Call nowHere is how a typical TPO roof goes on, from deck to seams.
A survey of the old roof usually includes a small core cut through the layers to check for trapped moisture and count existing roofs. Codes generally allow no more than two roof systems, so a roof that already has two must be torn off.
On a tear-off, the crew strips everything to the deck and replaces any sections that are soft or rusted. Where the old roof stays, a recovery board goes down first so the TPO does not ride on gravel or blisters.
Insulation boards are laid in staggered layers, with tapered sections built to move water off flat spots. Many energy codes require a minimum insulation value when a roof is replaced, so this layer is planned to meet it.
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. The roofer picks the method based on wind exposure, deck type and whether adhesive odors would bother the people inside.
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.
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.
New insulation boards sized for the energy code plus a cover board where the design calls for one.
Flashing at vents, curbs, skylights and walls built from the same membrane as the field.
White TPO membrane in the chosen thickness joined with welded seams instead of glue.
A sample cut through the old layers so wet insulation does not get buried.
Coated metal at the perimeter and around drains to hold the sheet down in wind.
New TPO roof installation is the cleanest version of the job, since there is no old roof to deal with. The deck, the drain locations and the insulation thickness are set first, then the attachment method is chosen to suit the wind exposure.
For Garfield homeowners, the usual TPO installation is a small roof where shingles cannot work because the pitch is too low. Shingles need a minimum pitch to shed water, so these low sections need a membrane. The tie-in where the shingles end and the membrane begins deserves extra attention, since that joint is where many small flat roofs leak.
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.
Recovering over one sound roof avoids hauling the old one away, when the code and the moisture survey allow it. A second recover is off the table on a roof that already carries two systems.
PVC membrane looks and installs much like TPO, with the same hot-air welded seams and many of the same flashing details. 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. For most Garfield homes and offices, TPO does the job, and PVC is worth considering over kitchens, labs or anywhere oils land on the roof.
Around Garfield, 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 Garfield and around Lodi, Elmwood Park, Wallington and Passaic 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. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder 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 Garfield is busiest after a hard winter and before the next one.
Small roof problems caught early usually stay small repairs.
Local roofers see the same roofs and storm damage across Garfield and nearby towns.
Ask the roofer about the cause, the options and the estimate before work starts.
