Bitumen is sometimes more commonly known as asphalt, and modified bitumen is asphalt combined with several substances that make it more suitable for roofing applications. Several pieces of your modified bitumen roofing system come together to form a watertight membrane that protects your commercial roof from the Florida climate.

Modified bitumen roofing products come in large rolls of roofing membrane that can be flattened over your roofing surface and joined with the other pieces of a single ply system to form a waterproof covering. Typically, steel or plywood decking is installed as a base for the entire roofing system. Insulation is then added to the top of the decking to provide added protection from the elements. A mechanically attached roof board tops the insulation and provides the platform that the membrane will be fastened to. The membrane is attached to the roof boardwith fasteners and heat is applied to join the seams of the membrane together.

Modern roofing membranes such as modified bitumen offer several advantages over their predecessor – asphalt flat roofing. Asphalt roofs have proven to be difficult to seal at its connecting points, where newer applications are virtually seamless which leads to fewer leaks. Traditional asphalt roofs also contract and expand in the heat of the day, creating the potential for cracks and leaks. In contrast, modified bitumen and other membranes, are designed to resist expansion and contractioncaused by fluctuations in temperature.

Pros of having a Modified Bitumen Roofing System

One of the biggest advantages to using modified bitumen roofing is its performance in extremely cold weather. This material was designed to remain flexible, even when the mercury falls well below freezing. Because it does not become brittle in cold weather, it is less likely to crack and create leaks.

Modified bitumen roofing is light in color and has heat-reflective properties. That means that it won’t retain heat on a sunny day, so your air conditioning system won’t have to work so hard to keep your building cool.

Finally, modified bitumen roofing is recyclable. When your roofing has come to the end of its useful lifespan, you don’t have to just commit it to a dump to sit forever. The pros definitely outweigh the cons with modified bitumen commercial roofing, including how kind it can be to the environment.
