Tapered Insulation Roof Systems

The goal of tapered roof insulation systems is to reduce or eliminate the amount of ponding/standing water on the finished membrane when the roof deck does not provide adequate slope. Draining the water in a timely and efficient manner minimizes the adverse effects that ponding/standing water can have on completed roof membranes. A properly designed tapered roof insulation system not only provides the positive drainage needed but also helps extend the life of the roof membrane and provides thermal value as well, reducing the heating and cooling expenses for the building owner.


Learning Objectives:
  1. Identify and understand key terms when designing a tapered system, including panel, repeat, slope, and cricket.
  2. Identify specific parameters to include in your tapered system.
  3. Identify building design requirements and which type of tapered insulation is appropriate.
  4. Understand what a cricket is and when to use it.
