Flat Roofing
TPO Roofing Cranford, NJ
A roofer in Cranford 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. Call (908) 562-6887 to reach a local 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. 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. Leaks come from under-welded seams, flashing that pulls away at walls and curbs, and penetrations sealed with caulk instead of proper boots. Tapered insulation and crickets that move water to the drains or scuppers keep the membrane from sitting under standing water.
Depending on what the roofer finds, tpo roofing in Cranford, NJ can go hand in hand with tpo roof repair and flat roof installation.

What a TPO roof job involves
A TPO roof is built in layers, and each one has a job.
Check the existing roof
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. Codes generally allow no more than two roof systems, so a roof that already has two must be torn off.
Tear off or recover
If the old roof is coming off, it is stripped to the deck, and rotted plywood or rusted steel deck is replaced. On a recover, a cover board goes over the old roof so the new membrane has a flat, solid base.
Install insulation boards
Rigid insulation, usually polyiso, is fastened or adhered over the deck, often in tapered boards that pitch water toward the drains. The insulation thickness is set partly by the local energy code, which often calls for more than the old roof had.
Roll out the TPO
The membrane is fastened at the laps or fully adhered, depending on the deck, the wind exposure and the design. Adhered sheets resist flutter in high winds, and fastened systems suit large open roofs.
Fuse the laps
Seams are welded with hot air, using a walking welder on long runs and a hand gun with a roller at corners. The finished seams are probed by hand so any gap is rewelded before the job is done.
Flash every detail
Vent pipes, curbs, drains and walls are each flashed with TPO welded to the field sheet. TPO-coated edge metal at the perimeter lets the membrane weld right to the edge.
What is included
Parts of a TPO roof
Curb flashing
Flashing at vents, curbs, skylights and walls so leaks do not start at the details.
Core cut
A check of the old roof for trapped water so wet insulation does not get buried.
Edge metal
New drip edge, coping or gravel stop at the roof edge with new drain rings where needed.
Insulation boards
New insulation boards sized for the energy code plus a cover board where the design calls for one.

TPO Roof Installation Cranford, NJ
New TPO roof installation is the cleanest version of the job, since there is no old roof to deal with. Drain or scupper locations, tapered insulation and the attachment method are worked out up front so the finished roof drains on its own.
Residential TPO installation in Cranford tends to mean smaller roofs: additions, carports, dormers with little pitch and flat sections behind a parapet. Below the minimum pitch for shingles, a welded membrane is far more reliable. 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 Cranford, NJ
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. Wet insulation left in place loses its value and can rust fasteners and steel decking from below.
Recovering over one sound roof avoids hauling the old one away, when the code and the moisture survey allow it. With two existing layers, a full tear-off is required in most places.

PVC Roofing Cranford, NJ
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.
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 Cranford, 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 Roofing Near Me
TPO roofs in Cranford 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 Cranford and around Garwood, Westfield, Kenilworth and Roselle Park see summer heat, heavy rain and the occasional strong storm, all of which test a flat roof at its seams and drains, so the best time to plan a TPO roof is before the old one starts leaking into the ceiling.

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

TPO Roofing FAQ
Do I have to tear off my old flat roof for TPO?
A survey of the old roof answers that question. If there is only one existing roof and the insulation is dry, a recover with a cover board is often allowed. Two existing layers or wet insulation mean a tear-off.
Does a white TPO roof save energy?
A white membrane reflects sunlight, which keeps the roof surface much cooler than a dark one. Less heat soaks through to the building, so the space under it can stay cooler in summer. Dirt buildup slowly reduces the effect.
Can TPO be used on a home?
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.
How long does a TPO roof last?
Most TPO roofs last roughly 15 to 30 years when they are installed and maintained well. Membrane thickness, how well the roof drains and how often people walk on it make the biggest difference.
How does TPO compare to EPDM rubber roofing?
Each has its strengths. EPDM is black rubber with adhesive or taped seams, and TPO is a white thermoplastic with welded seams. In hot, sunny areas and on roofs with many seams, TPO is often preferred, while EPDM has a long track record and is easy to patch.
