What Is Modified Bitumen Roofing?
Modified bitumen is a type of membrane roofing system engineered for low-slope and flat roofs. It is composed of asphalt blended with polymers, such as SBS (styrene-butadiene-styrene) or APP (atactic polypropylene), to enhance elasticity, strength, and overall performance.
These membranes are typically reinforced with fiberglass or polyester for added durability and are applied using one of several methods: torch-down, cold adhesive, or self-adhered installation.

SBS Modified Bitumen Roofing –
An asphalt membrane reinforced with rubberized polymers, SBS is known for its flexibility and thermal expansion properties. It performs exceptionally well in climates with wide temperature fluctuations.
APP Modified Bitumen Roofing –
APP is a plastic-modified membrane that offers enhanced UV resistance and weather durability. It forms a more rigid surface, providing excellent longevity and protection against environmental stress.

Frequently Asked Questions About Modified Bitumen Roofing
1. Why is modified bitumen a popular commercial roofing system?
It offers high flexibility, durability, and water resistance, making it ideal for Kannapolis-area businesses that need reliable protection from seasonal weather.
2. Can modified bitumen be used with other roofing systems?
Yes. It can be integrated with other systems such as metal, TPO, EPDM, or BUR for hybrid roofing applications that improve insulation, reflectivity, or structural support.
3. How does it differ from standard asphalt roofing?
Modified bitumen is enhanced with polymers and reinforcements, offering greater strength, flexibility, and weather resistance than traditional asphalt roofing.
4. Is it fire-resistant?
APP-modified bitumen membranes offer strong fire resistance, especially when combined with fire-retardant coatings. Always consult your contractor to choose a fire-rated system.
5. How does it handle rooftop foot traffic?
Modified bitumen is extremely durable under foot traffic, making it ideal for roofs that require regular access for HVAC maintenance or inspections.
6. Is insulation necessary?
While not required, insulation layers can significantly improve energy efficiency and are often included beneath the membrane.
7. Can leaks be repaired easily?
Yes. Leaks are typically isolated and can be patched or resealed without replacing the entire roof, making maintenance cost-effective.
8. How does it compare to other systems like TPO or metal?
9. What are the available installation methods?
- Torch-down – Durable but requires skilled professionals.
- Cold-applied adhesive – No flame required; safer option.
- Self-adhered – Quick installation for smaller or complex areas.
10. When should a modified bitumen roof be replaced?
If your roof is over 20 years old or shows signs of cracking, bubbling, or persistent leaks, it may be time to consider a full replacement.
11. Is it a sustainable roofing choice?
Yes. Modified bitumen systems increasingly use recycled materials, and reflective top layers can reduce energy use.
12. How does it perform in Kannapolis weather?
Modified bitumen handles summer heat, rainstorms, and freezing temperatures exceptionally well due to its flexible and weather-resistant design.
