TPO/PVC Roofs,

TPO white roofs are common today. TPO membranes are single ply roof membranes constructed from ethylene propylene rubber. They are created to combine the durability of rubber with the great performance of hot air weldable seams. These roofs have been tested to have a excellent resistance to ozone, and algae. They are also environ-mentally friendly and also very safe to install.

Modified Bituminous Roofs,

Modified roofs have a great resistance to cold temperatures, and also high temperatures. A few benefits of a modified roof are it has a proven track record. It contains superior waterproofing characteristics to work properly. These roofs have high tensile strength for maximum strength.

 
 

BUR-Built Up Roofs

Low cost, in most cases the cheapest one out of the flat roofs, built from 3 or more plies of waterproof material alternated with hot tar and covered with a layer of smooth river stone. Originally, built-up type roofs where made out of tar paper (organic), and asbestos based felt, but over the years more advanced materials have been developed and these types of roofs are currently using fiberglass mesh membranes.

Engineered Roofing Systems

JMI can convert a Low Slope Roof to a High Slope Roof as seen below. Our engineer will design a structurally sound pre-engineered truss system, custom fit to your building.
