NEW YORK CITY
Rooftop Copper Cladding
Architectural copper and Kemper waterproofing, completed by Maultz Construction.
THE SCOPE
Beyond a conventional roof.
Our work on this New York City rooftop included both the copper wall cladding and the Kemper waterproofing above it. The enclosure brought together vertical metal panels, corners, openings and a low-slope roof within a compact footprint.
For an owner or architect, that combination matters. The walls and roof meet at the same perimeter, so their details need to be considered together. Maultz’s scope covered both parts of the work.
LAYOUT & DETAILING
The work is in the junctions.
A broad wall offers a repeating panel layout. Corners and openings interrupt it. Resolving those interruptions is a central part of architectural metalwork: the panel widths, seams and edges have to work with the dimensions of the building.
Metal detailing also has to account for expansion and contraction as temperatures change. Choosing copper is only the starting point; how it is fitted and attached matters to the finished assembly.
LIVING WITH COPPER
A finish that changes with time.
New copper does not keep its original brightness indefinitely. Outdoors, it develops a natural patina that changes its appearance and helps protect the metal.
That gradual change is part of choosing copper for a building. It is a material whose appearance evolves, rather than a finish intended to remain exactly as it looked on installation day.
THE WATERPROOFING
Copper walls.
A Kemper roof.
The roof above the enclosure was also Maultz’s work. We installed Kemperol 2K-PUR, a solvent-free, odor-free waterproofing system, as part of the project’s roof and exterior scope.
Its odor-free formulation is particularly useful around occupied buildings and spaces where strong application odors would be disruptive. The liquid-applied resin and reinforcing fleece form a continuous membrane around changes in shape, including raised edges and drainage details.
The copper cladding and the roof membrane serve different parts of the enclosure. Completing both requires attention to where those materials meet, as well as to the individual surfaces.
