A roof failure rarely stays on the roof. Water finds its way into façades, ceilings and structure, and the cost of chasing it grows the longer it runs. We install and repair commercial roofing and waterproofing systems designed for New York’s freeze-thaw cycles, and we coordinate the work around the building’s occupants.
Where roofing and façade work meet at the parapet, sequencing them together under one contractor avoids duplicated access costs and keeps responsibility for the building envelope in one place.

Our own crews and access equipment handle the work from setup to closeout, with drainage, flashing and parapet details treated as part of the roof rather than afterthoughts — because that is where most roof failures begin.
