The Basics of Bitumen Roofing


Above all else, MB roofs are built to withstand harsh environmental conditions. They accomplish this by utilizing a system of layers, the same system used by BURs for over 100 years. 


However, MBs add a new twist to this system by topping it off with either a durable polymer layer or another durable cap that gives the whole system additional weather resistance and durability, a must for commercial roofs in Miami. The framework is a basic one and utilizes five unique layers to accomplish excellent results, but it’s a tried and true one that’s been proven to work for buildings of most shapes and sizes.

The Five Layers of Bitumen Roofing


The Bitumen Roofing system uses five key components to craft its unique, layered protection. These include:


    1. Insulation: provides the thermal resistance of the roof system to maximize efficiency
    2. Modified Base Sheets: specialized roofing felt that contains asphalt and serves as the base for other layers.
    3. Modified Bitumen Membranes: the part that sets MB roofs apart from BURs, factory-fabricated membrane, sheets made of specialized co-polymers, and fiberglass or polymer reinforcements.
    4. Adhesives: ties the entire system together and provides waterproofing to the roof, applied through various methods.
    5. Surfacing: the finishing touch, protects from UV rays that might otherwise deteriorate the other layers.

Each of these layers serves a specific and vital purpose within the roofing system. From thorough weatherproofing to reliable and efficient insulation, each layer provides a critical protection aspect to roofs in Miami, FL.

The Application Methods of Bitumen Roofing


Another unique feature of layered Modified Bitumen Roofing systems is that many application methods can impact their cost and their overall performance. These fit into three basic categories, which include:


    • The “hot-mop” method
    • The torch method
    • The cold-process method


The hot mop method is the same process used to apply BURs. It involves pouring hot adhesives such as asphalt over the various layers to pull and hold all the system’s various components together. This is the standard application process and offers predictable, reliable results. However, the price may be higher because the cost of involved materials such as petroleum can vary wildly.


The torch method involves melting asphalt by hand, rather than pouring it onto the roof pre-melted. This provides more consistent coverage and provides even better results than the standard hot-mop method. However, it can be even more expensive than the hot mop method, as it requires more hands-on work from your roofing team. 


Finally, cold process methods are among the newest options for these roofing types. Unlike the other two methods, they don’t use asphalt or other volatile organic compounds (VOCs) to bring the MB roof layers together. Instead, the cap comes in a large roll with its built-in adhesive. 


The roofer peels away a protective layer and then adheres to the sheet into place on top of the other layers. It’s a newer method but offers a “greener” experience than the other application processes.
