What Is ModBit Roofing? A Comprehensive Guide For Commercial Property Owners
When it comes to commercial roofing, choosing the right material is crucial for the long-term protection of your building. Among the many options available, Modified Bitumen (ModBit) roofing stands out as a popular choice for flat or low-slope roofs. But what exactly is ModBit roofing, and why might it be the right fit for your commercial property? In this blog, we’ll break down everything you need to know about ModBit roofing, from its composition to its benefits, helping you make an informed decision.

Understanding ModBit Roofing
Modified Bitumen, often referred to as ModBit, is a type of asphalt-based roofing material designed for buildings with flat or low-slope roofs.
ModBit is a hybrid material that combines traditional asphalt with modifiers like rubber or plastic, enhancing its strength, flexibility, and resistance to environmental factors. The material is typically applied in multiple layers, creating a robust, waterproof membrane that protects the roof from leaks, weather damage, and other potential issues.
How ModBit Roofing Is Made
The process of creating ModBit roofing involves the modification of asphalt with one of two types of polymers:
- Atactic Polypropylene (APP): APP is a plastic-based polymer that makes the asphalt more heat-resistant and durable. Roofs made with APP-modified bitumen are often torch-applied, meaning a torch is used to heat the material and adhere it to the roofing surface.
- Styrene-Butadiene-Styrene (SBS): SBS is a rubber-based polymer that adds flexibility to the asphalt, allowing it to better withstand temperature fluctuations. SBS-modified bitumen can be installed using hot asphalt, cold adhesive, or a heat-welded application.
Both types of ModBit roofing offer excellent performance, but the choice between APP and SBS will depend on the specific needs of your building and the climate in your area.
The Installation Process
ModBit roofing is typically installed in one of three ways:
- Torch-Applied: As mentioned earlier, this method involves heating the ModBit material with a torch and then adhering it to the roof’s surface. It’s a fast and efficient method but requires experienced professionals to ensure safety and proper application.
- Cold-Applied: In this method, the ModBit is applied using a cold adhesive, eliminating the need for open flames. This is a safer alternative to the torch-applied method, especially in buildings where fire hazards are a concern.
- Self-Adhered: Some ModBit membranes come with self-adhesive backing, making installation even easier. This method is often used for smaller roofing projects or areas that are difficult to access with other methods.
Regardless of the installation method, ModBit roofing typically involves laying down multiple layers, including a base sheet and one or more modified bitumen sheets, to create a durable, waterproof barrier.
Benefits of ModBit Roofing
ModBit Roofing offers a range of benefits that make it a strong contender for commercial properties located in Salisbury MD, Ocean City MD, Bethany Beach DE, Berlin MD, and the surrounding areas. The properties that ModBit has are:
- Durability: One of the key advantages of ModBit roofing is its exceptional durability. The multiple layers provide added strength, making it resistant to punctures, tears, and other damages.
- Waterproofing: The layered installation process ensures that ModBit roofing is highly effective at preventing water infiltration, reducing the risk of leaks and water damage.
- Flexibility: Thanks to the addition of SBS or APP modifieds, ModBit roofing can expand and contract with temperature changes without cracking, making it suitable for various climates.
- Ease of Maintenance: Modbit roofs are relatively easy to maintain, with repairs typically involving patching the affected area. This can extend the life of the roof and save on replacement costs.
- Cost-Effective: While not the cheapest option on the market, ModBit roofing offers a great balance between cost and performance. Its long lifespan and durability can result in significant savings over time.
- Versatility: Modbit roofing can be applied to various types of commercial buildings, from warehouses to office buildings, making it a versatile choice for property owners.
Considerations For ModBit Roofing
While ModBit roofing offers many advantages, there are a few considerations to keep in mind:
- Installation Expertise: Proper installation is critical to the performance of ModBit roofing. It’s essential to work with experienced roofing contractors who understand the material and the installation process.
- Heat Application: If opting for torch-applied ModBit, safety precautions are paramount. Improper handling of the torch can lead to fire hazards, so it’s crucial to hire a professional with the necessary skills and experience.
- UV Resistance: While ModBit is durable, prolonged exposure to UV rays can cause the material to degrade over time. To combat this, a reflective coating can be applied to extend the roof’s lifespan.
- Initial Cost: While ModBit is cost-effective in the long run, the initial installation cost can be higher than some other roofing options. However, this is often offset by the roof’s longevity and low maintenance requirements.
