New drip edge, coping or gravel stop at the roof edge so the edge stays sealed and tight.
Flat Roofing
TPO Roofing Hawthorne, NJ
TPO roofing in Hawthorne is a white single-ply membrane rolled over insulation and heat-welded at every seam, giving a reflective, watertight surface that stays cooler than old tar or rolled roofing. Dial (862) 434-1182 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. 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. Cold welds, wrinkles at the laps, unsealed edge metal and loose flashing around vents are where leaks start. Tapered insulation and crickets that move water to the drains or scuppers keep the membrane from sitting under standing water.
Many tpo roofing calls in Hawthorne also turn up a need for tpo roof repair or flat roof installation.

What a TPO roof job involves
A TPO roof is built in layers, and each one has a job.
Start with the deck
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.
Get down to a sound base
Old roofing is removed where needed, damaged decking is replaced and the surface is cleaned and made smooth. On a recover, a cover board goes over the old roof so the new membrane has a flat, solid base.
Install insulation boards
Polyiso boards go down next, and tapered panels and crickets are added where water needs help getting to drains or scuppers. The insulation thickness is set partly by the local energy code, which often calls for more than the old roof had.
Attach the membrane
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. Fully adhered roofs tend to be quieter in wind and look smoother, while fastened roofs go down faster.
Fuse the laps
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
Penetrations get molded boots or field-built flashing, curbs are wrapped and walls are flashed up and capped. TPO-coated edge metal at the perimeter lets the membrane weld right to the edge.
What is included
What goes into a TPO roof
Moisture check
A sample cut through the old layers so wet insulation does not get buried.
Welded membrane
TPO sheets fastened or adhered to the insulation so the roof acts as one continuous sheet.
Tapered insulation
Rigid insulation with tapered sections with slope built toward drains and scuppers.
Penetration flashing
TPO flashing welded around every opening so leaks do not start at the details.

TPO Roof Installation Hawthorne, NJ
A TPO roof installation on new construction or an addition starts with the deck and the slope, not the membrane. The deck, the drain locations and the insulation thickness are set first, then the attachment method is chosen to suit the wind exposure.
On homes in Hawthorne, 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 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 Hawthorne, NJ
A TPO roof replacement comes into play when repairs stop holding because the sheet or the insulation under it has worn out. 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.
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 Roofing Hawthorne, NJ
PVC roofing is the close cousin of TPO: a single-ply thermoplastic membrane with heat-welded seams. PVC handles fats, oils and some chemicals that can soften other membranes, so it often goes on restaurants and food plants.
PVC and TPO cannot be welded to each other, so repairs and additions have to match the existing membrane. For a Hawthorne roof with no grease or chemical exposure, TPO is often the simpler choice, while PVC earns its place where those exposures exist.

TPO roofs in Hawthorne show up on more than warehouses: low-slope additions, porches, garages and row homes use it as often as offices and stores do. Homes and buildings in Hawthorne and around Glen Rock, Haledon, Fair Lawn and Midland Park see summer heat, heavy rain and the occasional strong storm, all of which test a flat roof at its seams and drains, and a well-welded, well-drained TPO roof handles that better than a patched old surface.

How the weather here affects roofs around Hawthorne
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. Most homeowners in Hawthorne, NJ have the roof checked in the fall and again after the snow melts.

TPO Roofing FAQ
How does TPO compare to EPDM rubber roofing?
Both are proven flat roof membranes with different trade-offs. TPO is white and reflective with heat-welded seams, while EPDM is a black rubber sheet whose seams are joined with tape or adhesive. Welded seams give TPO an edge at the laps, and EPDM is valued for its flexibility and simple repairs.
Why are TPO roofs white?
White TPO bounces much of the summer sun back off the roof. A cooler roof surface means less heat moving into the building, which can lower air conditioning demand. Keeping the surface reasonably clean helps it stay reflective.
Is a TPO roof good for a house?
TPO works well on the low-slope parts of a house, such as porches, additions, garages and flat sections behind parapets. Steeper slopes are still better served by shingles or metal. The key on a house is the tie-in where the TPO meets the shingles or siding.
Can TPO go over my existing roof?
A survey of the old roof answers that question. A recover over a single, dry roof is usually possible. If there are already two roofs, or the insulation is wet, the old roofing comes off down to the deck.
How long does a TPO roof last?
A well-installed TPO roof commonly lasts somewhere around 15 to 30 years. Thicker membrane, good drainage and limited foot traffic push it toward the long end.
