Tapered Roofing Systems

Poor drainage on commercial roofs can result in damage far more destructive than either wind or other natural elements. Building owners often under estimate the advantages of tapered roofing when evaluating the life expectancy of a roof. Positive drainage is necessary to insure a safe, long lasting roof. Ponding water and freeze-thaw cycles can result in costly repairs and even pre-mature roof failure, which is rarely covered under warranty or by insurance. Positive sloped roof systems result in reduced maintenance and less stress to the building structure. Tapered roofing is equally suited for new and replacement construction. In new construction, this can be achieved by designing a slope into the structure of the building. In this case, the roofing support columns are varied in height so the final roof deck has high and low points from which to place the roof drains. The thickness of the insulation is varied to create the necessary slope. Expanded polystyrene is a logical, cost effective choice in low-slope roofing systems. Tapered EPS insulation provides the required positive slope to drain while retaining the structural and economic advantages of a flat roof deck. It maintains long-term thermal performance, dimensional stability and consistent moisture-resistance. EPS effectively controls the transfer of heat within all roofing systems.
