OVERVIEW

Traditional roofing systems are comprised of uniform materials throughout resulting in low-quality, low-cost systems; medium-quality, medium-cost systems; and high-quality, high-cost systems. To construct a high-quality, low-cost system a wide variety of materials must be used; they must be used in the right way; and they must be used prudently. In other words, only by applying the right materials in the right manner is it possible to construct a high-quality, low-cost system.
