Abstract
cold applied roof coatings, mastics and adhesives have been used in the maintenance, restortion and in the construction of new roofing membranes. Significant changes in commerical hot applied and single ply roofing materials and application techniques took place during the period of 1970 to the mid-80s'. Evolutionaly changes continue in this area as the newer systems continue to be improved based on real time performance. Tech;nological change related to polymer modification of asphalt andsolvent reduction is occurring in the cold applied roofing area as the industry moves toward the 21st century. There is also an emerging technology of liquid applied asphaltic materials that are solvent free. New technology is also being applied to the asphalt emulsstion coatings and acrylic latex based white roof coatings to reduce the amount of water in these materials to enhance the speed of drying as well as imporove the adhesion to common roofing materials. While the existing cold-applied roofing products will continue to have an important place in the roofing industry, the 21st century will see improvements in these products and new technologies applied to roofing materials that will provide new levels of performance in cold applied coatings, mastics and adhesives.
