BUR (Built-Up Roof)
Hot-Mopped
One of the oldest application methods still used today, involves melting blocks of asphalt in a large kettle and spreading the melted asphalt on the roof with mops.
Heat-Welded/Torch-Applied
Using a torch, the installer will melt the asphalt on the underside of the membrane. This will allow the sheet to adhere to the substrate below.
Cold-Applied
The installer will attach the roofing membrane by applying a liquid adhesive (i.e., Matrix 101) with a tool such as a notched squeegee or an applicator gun to the substrate or previously applied layer of roofing material.
Self-Adhered
This fast growing asphaltic installation method involves rolling out a membrane and peeling the film backing to adhere the membrane. This method can increase the speed of installation over the other three methods and does not produce unpleasant odors.
