COLD PROCESS ROOF SYSTEMS

Cold Process Roof Systems have been one of the most successfully installed roof systems since their introduction in the early 1900’s. Cold Applied technology offers many benefits to the building owner and facility manager as well as the contractor. Cold applied roof systems offer tremendous durability, life expectancy, ease of maintenance while avoiding issues such as odor, burn hazards and disruptions to the facility below. Cold applied roof systems are considered the best roof system available by many leading industry professionals.

OVERVIEW & BENEFITS OF COLD PROCESS ROOFING

For well over 100 years, low slope roofs in North America were constructed of felts or plies bonded together and waterproofed utilizing hot applied asphalts or hot applied coal tar pitch. These bitumens were heated in various types of roofing kettles with temperatures in excess of 500°F.

There were a number of negatives factors that simply went along with the use of these industry-wide techniques; including fires, and compromised workers' safety due to acccidents when this molten material, hot asphalt or hot coal tar, burned a human being. In addition, in order to install a good roof system, the hot bitumen needed to be controlled by maintaining these high temperatures. Bitumen allowed to cool and then applied created roof systems with built-in problems including voids and inter-ply blisters.

Some 30 years ago cold process waterproof mastics and adhesives were developed and offered to the commercial roofing marketplace. Again using felts or plies, the traditional built-up roofs could now be installed using a cold process bitumen instead of the hot kettle fired bitumen. These cold process products were solvent-based and acted as the bonding glue and waterproofing of the built-up roof system.

Over the years the cold process materials have been enhanced via new asphalt polymer chemistry. Therefore, cold process materials now are available in economy grades up to high performing rubberized versions meeting demands of 21st century light weight roofing construction. By using cold process, all the hazards of the kettle-heated asphalts are eliminated: no fires, limited fumes and odors, no skin and muscle burns.

When constructing a new roof or replacing an old unsalvageable roof, consider the application of a cold applied modified bitumen membrane system or a traditional built-up roof using this safe, high tech cold process method.
