    COLD PROCESS VS.
    OTHER ROOFING SYSTEMS

    HERE IS A LOOK AT THE MOST COMMON TYPES OF ROOFING AND THEIR INHERENT PROBLEMS

    Why Not Hot Asphalt?
    The Cold Process Roof System out performs hot asphalt in re-roof applications because it will not blister up due to the heating of moisture in the existing roof  normally associated with applying hot asphalt. What’s more, the Polyester Mat used in the Cold Process System is far superior in strength and flexibility to organic or fiberglass felts used with hot asphalt. The Cold Process Coating itself, does not get brittle in cold temperatures as does hot asphalt.

    Why Not Torch Down Rubber?
    The major problem with torch down rubber roofing is that small cracks develop throughout the material especially at the seams which are every 3 feet. Another aspect which bears mention is the fires which have developed long after the last torch was put out due to smoldering insulation and other ignitable materials the flame comes in contact with. Most torch down roofs that were never protected with an aluminum coating, will last only 5 years before needing to be serviced.

     

    Why Not Single-Ply Sheet Roofing?
    The first and foremost problem with single-ply sheet roofing is that the glue used in the overlaps fails well before the membrane. The Cold Process System is a retrofit system which means there is no air space between the existing roof and newly installed roof. Single-ply sheet roofing sheet roofing requires a layer of insulation or recovery board between existing roof and the single-ply sheet roofing material. This recovery board needs to be screwed down through the existing roof basically making the existing roof dead weight on the building structure, serving no purpose as mentioned earlier.

    The existing roof is used as a substrate to which the Cold Process Asphalt is fully adhered. The Cold Process Roof adds less than 1lb. per square foot to the existing roof so weight build up is not a factor. In comparison, a wet 18 inch snowfall will add about 15 lb. per sq. ft., as will a gravel ballasted single-ply sheet roofing system.

    Shrinkage
    Robbins Roofing has already had to tear off a thermal plastic PVC roof due to shrinkage. Even at 1% shrinkage accustomed to thermal plastic roof materials, if a roof measures 200’x 200’ the material will shrink 2 feet in both directions. Where does the additional material come from? In this case, the material pulled off the parapet walls leaving them exposed and leaking.

     

    Long-Term Considerations
    If indeed the manufacturers of a single-ply sheet roofing product lasts for the 10 to 15 years they claim, what does the building owner do after the warranty has expired and the roof begins to leak? In almost all cases, the answer is a costly tear-off and start again. What makes the Cold Process System so cost effective is that it is maintainable. The addition of another layer of Polyester will cost about 1/3rd that of tearing off and replacing a single-ply sheet roofing system, and will provide for a 10 Year Guarantee, adding less than one pound per square foot to the roof.
