The presentation will examine the history of modified bitumen as well as their major features and benefits. The use of modified bitumen membranes in new, re-roofing and recover applications in both conventional and protected membrane assemblies will also be covered. The demonstration will show the installation of a modified bitumen roofing system from the deck up including the vapour retarder, the primary insulation and a cover-board application. The modified bitumen membrane will then be installed showing the base sheet and cap sheet, treatment of the edges and corners, and fastening and attachment techniques.
