Modified Bitumen Roofing
Modified Bitumen Roofing Services
Modified Bitumen is a durable commercial roof system commonly used on low-slope and flat commercial roofs.
Throughout coastal South Carolina, eastern North Carolina, and surrounding regional markets, CCR Roofing installs, repairs, maintains, and replaces Modified Bitumen roof systems for commercial property owners, facility managers, contractors, and business owners.
Our team works with both SBS and APP Modified Bitumen systems and can help determine whether this roof system is the right fit for your building.
A Durable Commercial Roofing System for Low-Slope Roofs
Modified Bitumen, often called Mod Bit, is a commercial roofing system commonly used on low-slope and flat roofs. It is made with asphalt-based roofing membranes that are modified with polymers to improve specific performance characteristics.
The two most common types of Modified Bitumen systems are SBS and APP. SBS systems are often associated with flexibility and elasticity. APP systems are often associated with weather resistance and heat-applied applications.
CCR Roofing works with both SBS and APP Modified Bitumen systems, giving commercial property teams a knowledgeable partner for installation, repair, maintenance, and replacement planning.
When to Consider a Modified Bitumen Roof System
Modified Bitumen may be a strong option for certain commercial properties, especially low-slope roofs where a durable membrane system is appropriate. Modified Bitumen may be worth considering if your property has:
- A low-slope or flat commercial roof
- An existing Modified Bitumen roof that needs repair
- A re-roofing or replacement opportunity
- A need for a durable commercial roof system
- Frequent rooftop equipment access
- Flashing, seam, or surface wear concerns
- A property team comparing membrane and multi-layer roof systems
- Long-term roof asset management needs
SBS & APP Modified Bitumen Systems
CCR Roofing works with both major Modified Bitumen system types: SBS and APP.
SBS Modified Bitumen
SBS Modified Bitumen systems are commonly associated with flexibility and elasticity. These systems may be considered for low-slope commercial roofs where movement, weather exposure, and roof details need careful attention.
APP Modified Bitumen
APP Modified Bitumen systems are commonly associated with weather resistance and heat-applied applications. These systems may be considered for commercial roofs where a durable modified membrane system is appropriate.
Choosing Between SBS & APP
The right choice depends on the building, roof condition, existing system, application method, climate exposure, maintenance needs, and long-term property goals. CCR Roofing can evaluate your roof and recommend the right approach based on the condition of your property and the system already in place.
Talk With Our Team →Modified Bitumen Roofing Benefits & Considerations
Durable Commercial Roof System
Modified Bitumen is designed for low-slope commercial roofing applications and can provide a durable roof system when properly selected, installed, and maintained.
SBS & APP Options
Because Modified Bitumen includes SBS and APP system options, property teams have more than one path depending on project needs and existing roof conditions.
Multiple Application Methods
Modified Bitumen systems may be installed using different methods depending on the product, project, and manufacturer requirements. Application methods may include heat-applied, self-adhered, cold-applied, or hot-applied approaches.
Repair Support
Many Modified Bitumen roof issues can be repaired when the damage is isolated and the system is otherwise in serviceable condition.
Maintenance Still Matters
Like any commercial roof system, Modified Bitumen should be monitored over time. Surface condition, seams, flashing, drains, penetrations, and rooftop equipment areas should be reviewed regularly.
System Selection Still Matters
Modified Bitumen may be the right fit for some commercial buildings, but TPO, PVC, EPDM, Built-Up Roofing, or Metal Roofing may be more appropriate depending on the property.

Modified Bitumen Roof Installation
If you are planning a new commercial roof, re-roof, or replacement project, CCR Roofing can help evaluate whether Modified Bitumen is the right system for your building. Our team considers the building, roof slope, drainage, existing roof condition, exposure, rooftop equipment, and long-term performance goals before recommending a Modified Bitumen roof system.

If your existing Modified Bitumen roof is leaking, damaged, or showing signs of wear, CCR Roofing can inspect the issue and recommend a practical repair approach. Common Modified Bitumen repair needs may involve cracks, splits, blisters, surface wear, flashing, seams, penetrations, rooftop equipment areas, or drainage concerns.

Modified Bitumen roofs should be monitored over time to identify small issues before they become larger problems. CCR Roofing's Roof Armor Performance Program can help property teams monitor Modified Bitumen roof condition, address vulnerable areas, and maintain better documentation. Photos are included with each invoice for repair and maintenance work.

Modified Bitumen roofs can perform well when they are properly selected, installed, and maintained. However, commercial property teams should still monitor the system for signs of damage, wear, or water intrusion. Potential Modified Bitumen roof concerns include:
- Cracks or splits
- Blisters
- Open seams
- Surface wear
- Flashing concerns
- Drainage problems or ponding water
- Damage around rooftop equipment
- Storm or wind damage
- Edge or perimeter issues
- Recurring leak areas
- Wear around penetrations
Is Modified Bitumen the Right Roof System for Your Building?
Modified Bitumen is a recognized commercial roof system, but every property should be evaluated based on its conditions and goals.
Modified Bitumen vs. TPO
Modified Bitumen is a commercial roof membrane system often used on low-slope roofs. TPO is a single-ply thermoplastic membrane commonly selected for reflectivity, heat exposure, and practical value.
View TPO Roofing →Modified Bitumen vs. PVC
PVC is a single-ply membrane that may be a stronger consideration for buildings with grease, chemical, exhaust, or demanding rooftop exposure needs. Modified Bitumen may be considered where a durable bituminous roof system is appropriate.
View PVC Roofing →Modified Bitumen vs. EPDM
EPDM is a synthetic rubber single-ply membrane. Modified Bitumen is a different commercial roofing system commonly used on low-slope roofs and available in SBS and APP options.
View EPDM Roofing →Modified Bitumen vs. Built-Up Roofing
Modified Bitumen and Built-Up Roofing are both used on low-slope commercial roofs, but they are not the same system. Modified Bitumen uses modified membrane sheets, while Built-Up Roofing is a multi-layer roof assembly.
View Built-Up Roofing →Modified Bitumen vs. Metal Roofing
Modified Bitumen adds layered protection to a low-slope roof, while metal roofing depends on a compatible slope and structural design. Which one fits your building often comes down to the roof's shape and how much redundancy you want in the assembly.
