The goal of tapered roof insulation systems is to reduce or eliminate the amount of ponding or 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 on roof membranes. A properly designed tapered roof insulation system not only provides the positive drainage needed, it also helps extend the life of the roof membrane and provides thermal value, reducing the heating and cooling expenses of the building owner.
