The flat-roof systems we service
NYC flat roofs are typically TPO, EPDM (rubber), modified bitumen, or older built-up tar-and-gravel. Each fails differently and needs the right repair method — a patch that works on modified bitumen won't hold on TPO. We identify your system correctly and repair it the way it's meant to be repaired.
Getting the material and method right is the difference between a lasting fix and a leak that returns in a few months.
Why flat roofs leak in NYC
The usual culprits are failed seams, cracked flashing around parapets and vents, clogged drains that cause ponding, and membrane damage from foot traffic and winter freeze-thaw cycles. Ponding water is especially damaging because it works into any weak point and accelerates deterioration.
We trace the actual source — which is often not directly above the interior stain — and fix the cause rather than just the symptom.
Repair vs. replacement
Not every failing flat roof needs full replacement. If the membrane is largely intact and the damage is localized, targeted repairs can extend its life for years. We give you an honest assessment of whether a repair will hold or whether replacement is the smarter spend, so you're not paying for more than you need.
