Metal building owners have a wide variety of roofing systems to choose from. but few have been
designed specifically for the restoration and maintenance of metal roofs. Instead traditional
roofing materials have been forced to conform with the unique requirements of the metal substrate.
Aesthetic considerations aside, asphalt coatings are too brittle to bridge thermal-induced
movement along seams, end laps, fastener heads, and roof protrusions. While single-ply systems
provide a durable membrane, these materials were not designed for use over corrugated, irregular
surfaces. Single-ply installations depend upon a flat surface mechanically fastened to the
existing metal deck, a requirement which can add significant weight stress to the substrate.
This rather costly approach also relies heavily on yet another set of fasteners perforating the
original metal roof.
From this perspective, the use of lightweight, flexible coatings emerged as a major contributor in
the metal roof restoration industry. These liquid rubber systems, referred to as elastomeric coatings,
present an alternative to traditional asphalt and single-ply techniques. At the Youngstown
Warren Airport in Youngstown, OH, the use of a fully adhered, seamless rubber membrane was
viewed as an aesthetically pleasing, economically acceptable option. The search began for an
elastomeric system that provided the airport the maximum value for their roofing dollars. Truco's
Thermoplastic elastomeric surpassed all others for this project.
Unlike most elastomeric coatings, Truco's rubber does not require systemic reinforcement over
vertical seams and fasteners. We've been specifying our synthetic rubber coatings for eighteen
years resulting in quality formulations supported by close communication with our applicators.
Other properties include tenacious adhesion, high tensile strength, chemical & UV resistance
and low moisture permeability. These components combine to produce a roofing systems of
unparalleled quality. A system which when properly applied, assures building owners
"Economical Quality Through Innovative Chemistry."
