More Information About Modified Bitumen Roofing
Modified bitumen is asphalt that has modifiers added to it to give it plastic or rubber-like properties. They are typically installed as a two-ply system and are almost always fully adhered.
There are two types of modified bitumen membranes that we install:
SBS polymer-modified bitumen – these are commonly installed in hot moppings of asphalt or cold adhesive. Many of the new products are available in a self-adhering roll.
APP modifiers are usually heat welded or applied using a torch. SBS modifiers give asphalt a rubberized quality, while APP modifiers give it a more plasticized quality.
Our modified bitumen products have two types of surfaces; mineral coated or smooth surface. Here are steps followed by us to install modified bitumen.
- First, our experts often need to remove the old roof down to the decking
- Next, we install fiber-board insulation on top of the decking to increase strength and moisture resistance
- Then, a base sheet is installed which is either mechanically fastened or self-adhered
- The final step is installing the modified bitumen membrane which can be hot-mopped, torched, or applied using a cold process
