ROOFING – SYNTHETIC PROFILED ROOFING
J.W. Gray & Co. proudly offers the latest innovation in synthetic profiled roofing, the Bermuda TrueRoof System.
Comprised of profiled extruded polystyrene panels, typically fastened to a reinforced cement board substrate. A fiber reinforced cementitious screed is then applied, finished with successive layers of protective reinforced mesh, and potable grade elastomeric coatings. The resulting system is a fusion of traditional esthetics, and contemporary strength and flexibility.
The Bermuda TrueRoof System offers:
- superior low slope applications,
- enhanced resilience and flex
- adaptable and customizable system with an array of design options to suit most any project
- potability compliant
- zero storm failure rate
- cutting edge system components
ROOFING – FULLY REINFORCED LIQUID APPLIED ELASTOMERIC SYSTEMS
These systems utilize reinforced cloth and elastomeric coatings applied in varying degrees according to project requirements. Typical reinforced applications consist of a reinforced mesh embedded in a basecoat, which then receives successive coatings of heavy duty elastomeric coatings. The result is a system that can resists the elements, while remaining flexible enough to handle nominal substrate flex.
We offer fluid applied reinforced membrane systems featuring:
- excellent flex and coverage protection
- versatile applications, from minor service
- treatments to entire field membrane installations
- adaptable system options, allowing for overall coverage density for budget conscious applications
- component options range from potability compliant coatings, to heavy duty grey water catchment coatings
ROOFING – REINFORCED SINGLE PLY MEMBRANE & ISOCYANURATE SYSTEMS
For projects that require enduring roofing solutions for large flat areas, we offer systems based on an isocyanurate substrate, with a single ply membrane adhered and fastened over top. Pairing these two materials can provide flat roofs the slope needed for drainage, with the long lasting, superior protection afforded by a single ply membrane.
System features include:
- customized roof taper designs, providing drainage designed according to project conditions
- superior wind uplift resistance
- extremely low maintenance
- resilient membrane, resisting punctures, UV, & elemental damage
- potability compliant
- complete range of roofing accessories, ensuring all project conditions can receive the same level of protection
- hot air welded seams, offering excellent protection
