Installing T-Joints on Modified Bitumen Roof Systems
T-Joints occur on modified bitumen roof systems at the interface of the end laps to the side laps. This is a critical juncture in the roof system.
One application modification that has proved to be successful has been in the installation of membrane T-joints. T-Joints occur on modified bitumen roof systems at the interface of the end laps to the side laps. This is a critical juncture in the roof system because it is where three layers of material are adjoined as one. In a typical modified bitumen system application, this condition presents itself at all end laps. The most prominent concern at these points is that if they are not properly adhered, moisture can enter the system.
