With the rising cost of building materials and the eradication of environmental resources it is not feasable or profitable to incur expensive annual life cycle costs or to replace a roof every 10 to 15 years. The life cycle cost of a roof is a defined as the present value of all costs associated with the roof from initial installation until reroof. Sustainable roof systems are becoming increasingly important. Sustainable systems preserve natural resources, reduce landfill waste and provide maximum life cycle cost efficiency. Bayseal’s tenacious ability to adhere to most surfaces provides a watertight monolitihic seal around penetrations, up parapet walls, and other parts of the structure without the use of mechanical flashings, in most cases, thus eliminating seams and joints.
