The average life expectancy of a properly installed mod bit roof ranges from 20 to 25 years. These systems are tough, weather-tolerant, and resistant to cracking, tearing, and UV rays.
With two or more layers of protection and alternating layers of adhesive and membrane, mod bit roofing systems offer outstanding defense against water infiltration, even during heavy rainfall and high winds.
Certified Commercial Roofing offers a range of installation methods based on your building’s needs:
Reflective cap layers and granule-surfaced membranes reduce heat absorption, helping keep commercial properties cool and reducing labor costs tied to air conditioning. These systems are considered environmentally friendly and are a common solution for those seeking a cool roof design.
Our systems are engineered to handle Houston’s elevated temperatures, high humidity, and seasonal cold temperatures. Modified bitumen mod bit membranes are known for their elasticity and tensile strength, which helps accommodate thermal movement and prevent damage.
Whether you operate an industrial facility or a high-traffic commercial space, mod bit systems are built to endure regular foot traffic without compromising performance.
Compared to TPO or PVC, modified bitumen roofing products offer better resistance to punctures and tears. Built up roofing systems, while still viable, often lack the flexibility and modern advantages of mod bit systems. Below is a comparison:
| Feature | Mod Bit Roofing System | TPO | BUR |
|---|---|---|---|
| Service Life | 20 years or more | 15–20 years | 10–20 years |
| UV Resistant | Yes | Yes | Moderate |
| Strong Odor During Install | Low (Self Adhered) | Yes | Yes |
| Foot Traffic Resistance | High | Moderate | Moderate |
| Multi Ply System | Yes | No | Yes |
| Applications | Commercial & Residential | Commercial | Commercial |
Modified bitumen mod bit systems are used in:
These systems have become an industry standard in the roofing industry due to their versatility, ease of maintenance, and robust protection.
Mod bit roofs are considered one of the most cost-effective options available, especially considering their low maintenance and average life expectancy. While labor costs vary depending on the installation method and site conditions, the total investment is typically lower than other systems over the life of the roof.
Modified bitumen roofing is a type of commercial roofing system that is made from asphalt and rubber modifiers. It is designed to provide excellent durability and weather resistance, making it a popular choice for flat or low-slope roofs. Here are some situations when a modified bitumen roof may be a good choice:
Low-slope or flat roofs: Modified bitumen roofing is ideal for low-slope or flat roofs that have a slope of 3:12 or less. It provides superior water resistance and protection against the elements.
High-traffic areas: Modified bitumen roofing is highly durable and resistant to impact damage, making it a good choice for areas with high foot traffic or equipment that may cause damage to the roof.
Extreme weather conditions: Modified bitumen roofing is designed to withstand extreme weather conditions such as high winds, heavy rain, and hail. It is also resistant to UV rays, which can help extend the life of the roof.
Retrofit projects: Modified bitumen roofing can be installed directly over an existing roof, making it an ideal choice for retrofit projects where the existing roof is in poor condition or needs to be replaced.
Energy efficiency: Modified bitumen roofing can be installed with a reflective coating, which can help reduce cooling costs and improve energy efficiency.
Overall, modified bitumen roofing is a versatile and reliable option for a wide range of commercial and industrial buildings. It's important to consult with a licensed roofing contractor to determine whether modified bitumen roofing is the best fit for a specific building or structure.
Modified bitumen roofs are generally considered to be a mid-range commercial roofing option in terms of cost. The exact cost of a modified bitumen roof will depend on several factors, such as the size and complexity of the roof, the location of the building, and the specific installation method used.
In general, modified bitumen roofs are more expensive than traditional asphalt roofs but less expensive than other commercial roofing options, such as TPO and PVC. However, they offer superior durability and weather resistance compared to traditional asphalt roofs, making them a cost-effective option in the long run.
Additionally, modified bitumen roofs can be installed with reflective coatings to improve energy efficiency and reduce cooling costs. This can provide additional cost savings over the life of the roof.
It's important to obtain a detailed cost estimate from a licensed roofing contractor based on the unique specifications of the project. The cost of a modified bitumen roof will vary depending on the specific needs and requirements of the building.
Yes, there are several different names for modified bitumen roofs. These names can vary depending on the specific formulation of the roofing material, the manufacturer, and the region where the roofing is installed. Here are some of the common names for modified bitumen roofing:
Mod Bit: Mod Bit is a common shorthand term for modified bitumen roofing.
SBS roofing: SBS (Styrene-Butadiene-Styrene) is a type of rubber modifier that is often used in modified bitumen roofing. SBS roofing refers to roofing systems that use SBS as a modifier.
APP roofing: APP (Atactic Polypropylene) is another type of modifier that is used in some modified bitumen roofing systems. APP roofing refers to roofing systems that use APP as a modifier.
Torch-down roofing: Torch-down roofing is a specific installation method for modified bitumen roofing. It involves using a propane torch to heat the roofing material and melt it onto the roof surface.
Peel-and-stick roofing: Peel-and-stick roofing is another installation method for modified bitumen roofing. It involves applying the roofing material to the roof surface using an adhesive backing, without the need for heating or torching.
Overall, the name for a modified bitumen roof can vary depending on the specific materials used and the installation method. It's important to consult with a licensed roofing contractor to determine the most suitable modified bitumen roofing system for a specific building or structure.
There is no legal requirement for a roofer to be certified to work with modified bitumen roofing. However, it is highly recommended that a roofer have the appropriate training and experience to install or repair modified bitumen roofing.
Installing modified bitumen roofing requires specific knowledge and techniques, and mistakes during installation can lead to costly leaks and other problems. Additionally, some roofing manufacturers offer training and certification programs for contractors who wish to install their modified bitumen roofing products. Certification from a modified bitumen roofing manufacturer can provide building owners with additional assurance that the installation will be done correctly and to the manufacturer's specifications.
Ultimately, the best way to ensure a successful modified bitumen roofing project is to work with a licensed roofing contractor who has experience and training in working with modified bitumen roofing. Be sure to ask the contractor about their experience with modified bitumen roofing and whether they have any certifications or training in this area.
