Call (929) 219-1763TPO Roof Repair Cost in Brooklyn
TPO is repaired by heat-welding new TPO onto the old sheet, so the price mostly depends on how many feet of seam or flashing need welding and whether the old membrane is still clean and soft enough to take a weld. Most TPO repairs in Brooklyn cost $300 to $1,500.
What changes the price
- Length of seam or flashing that needs re-welding
- Age of the TPO: older, chalky sheet needs extra cleaning before it will weld
- Wet insulation under the leak that has to be cut out and replaced
- Roof access: ladder, roof hatch or bulkhead stairs

Signs Your TPO Roof Needs Repair

- Seams lifting or separating where two sheets meet
- Punctures, cuts or scuffs near HVAC units and the roof hatch

- Cracking or chalky surface on an older, weathered TPO roof
- Membrane loose or billowing in the wind
- Scorched or shrunken spots from past torch or hot-air repairs
How We Repair a TPO Roof
A TPO patch only lasts if it truly welds to the old membrane. Preparation is most of the job.
- Find the sourceWe trace the leak to the exact seam, flashing or puncture and photograph the damage.
- Clean and prepareWeathered TPO is scrubbed and cleaned so the new material can weld to it.
- Heat-weld the repairA matching TPO patch or seam strip is welded in place with hot air, never glued or tarred.
- Probe, photos, warrantyEvery weld is checked with a probe, then you get before-and-after photos and your warranty in writing.
Why TPO Roofs Fail in Brooklyn
- Weak welds from the original install. Seams welded too cold or too fast can open years later.
- HVAC and equipment service. Dropped tools and foot traffic puncture the membrane around rooftop units.
- Sun and temperature swings. Brooklyn’s hot summers and freeze-thaw winters age the membrane and stress the flashing.
- Movement at walls. The building shifts with heat and cold, pulling flashing away from parapets and curbs.
When Repair Isn’t Enough
Most TPO roofs can be repaired for years. We’ll recommend a new roof only when the membrane is brittle and cracking across the roof, the insulation underneath is wet over large areas, or seams are failing everywhere. You’ll see photos and get both prices so you can decide.

Call (929) 219-1763How long does a TPO roof repair take?
Most TPO repairs are done in a few hours to one day. Welding needs a dry roof, so in rain we make a temporary seal and finish once it dries.
Can you repair a TPO roof in winter?
Yes. TPO can be welded in cold weather as long as the surface is dry and clear of snow and ice. We adjust the welder for the temperature and test each weld.
Will a repair affect my TPO manufacturer warranty?
If your roof is still under a manufacturer warranty, check its terms first. Some require repairs by a certified contractor. Send us the warranty and we’ll tell you how to keep it valid.
Is it safe to walk on a TPO roof?
Yes, carefully. TPO is slippery when wet and can be punctured by tools or sharp debris. Walkway pads protect the areas people use most, such as around HVAC units.
