Roof systems, leak diagnosis, and preventive maintenance for Manhattan's elevator buildings and rowhouses — built around occupied-building schedules and DOB permit requirements.
Manhattan's elevator buildings and rowhouses put different demands on a roof system than a standalone building does — crowded rooflines packed with satellite dishes, HVAC units, and shared party walls mean access and coordination matter as much as the membrane itself. We work around building management schedules and DOB permit requirements common on Manhattan roof replacement jobs, and we diagnose leaks in occupied units without guesswork or repeat visits.
A fire at a Harlem building left a section of the roof deck badly damaged, burning through to the wood framing below — and with a storm moving in right behind it, there wasn't time for a normal repair timeline. Our crew opened up the affected area the same morning to assess the full extent of the damage, then got to work immediately. New insulation board went down that same afternoon, followed by a fully adhered modified bitumen membrane sealed tight around the roof's pipe penetrations. By late afternoon the entire section was sealed under a protective reflective coating — watertight before the storm arrived that night. One emergency call, a weatherproofed roof by evening.

A property management client in Inwood came to us with a recurring leak that a previous patch job hadn't actually solved. Finding the real source on an occupied roof takes more than a guess and a bucket of sealant — we traced it back through the seams and flashing, made the repair properly, and sealed the full section under a fresh reflective coating. We don't treat cleanup as the finish line: we follow up with every property management client after the job to confirm the fix is holding through the next rain, which is exactly why they call us first the next time something comes up.

A landlord client on the Upper West Side came to us with a roof well past its service life — cracked, patched over in places, and no longer holding up. Rather than another temporary fix, we handled a full roof replacement: tearing off the aging membrane and installing a new white asphalt (modified bitumen) roofing system built to handle NYC weather for years to come. We also re-clad the rooftop bulkheads in new aluminum sheeting, giving those structures a clean, weathertight finish and a new life alongside the rest of the roof. Every new roof we install is backed by a contractor's warranty, so our clients get a professional job done to spec — and the assurance that we stand behind it.
