What Is Modified Bitumen Roofing?
Modified bitumen is a membrane-based roofing system built for flat or gently sloped roofs. It combines asphalt with polymer modifiers—SBS (styrene-butadiene-styrene) for rubber-like flexibility or APP (atactic polypropylene) for enhanced UV and heat resistance. These membranes are typically reinforced with fiberglass or polyester, giving them added strength and puncture resistance.
Two Main Types of Modified Bitumen Roofs
SBS-Modified Roofing:–
Flexible and resilient, perfect for regions with seasonal temperature shifts.
APP-Modified Roofing:
Durable and UV-resistant, ideal for buildings exposed to direct sunlight

Frequently Asked Questions About Modified Bitumen Roofing
1. Why is modified bitumen ideal for commercial buildings?
It’s built for flat and low-slope roofs, offering waterproofing, flexibility, and UV resistance—key qualities needed for North Carolina’s changing weather conditions.
2. Can modified bitumen be used with other systems?
Yes. It can be layered with TPO, PVC, BUR, or even metal for hybrid systems that enhance insulation or reflectivity.
3. How is it different from traditional asphalt roofing?
Modified bitumen contains polymer reinforcements that improve flexibility and longevity, unlike standard asphalt which is more prone to cracking.
4. Is it fire-resistant?
Yes. APP-modified systems often include fire-resistant additives, and we offer systems with Class A fire ratings.
5. How does it hold up to foot traffic?
Very well. It’s highly durable and can handle regular maintenance visits. Walk pads or coatings can be added for high-traffic zones.
6. Should I add insulation beneath it?
Yes. Installing rigid insulation boards underneath the membrane improves energy efficiency and reduces heating and cooling costs.
7. What if my bitumen roof starts leaking?
Leaks are uncommon but repairable. Our team can patch, seal, or replace problem areas quickly and efficiently.
8. Is it better than TPO or EPDM?
It depends. Modified bitumen is more puncture-resistant, while TPO and EPDM are lighter and more reflective. We’ll recommend the best option for your property.
9. What installation method is best?
- Torch-down: Durable and long-lasting, but requires fire safety precautions
- Cold-applied: Safer, no open flames needed
- Self-adhered: Fast, efficient, and great for smaller buildings
10. When should I replace my bitumen roof?
If your roof has persistent leaks, widespread cracking, or is over 25 years old, it’s time to consider a replacement.
11. Is it environmentally friendly?
Many systems now incorporate recycled content and reflective surfaces to reduce heat absorption and environmental impact.
12. How does it perform in North Carolina weather?
Modified bitumen is ideal for North Carolina’s hot summers, wet seasons, and winter freezes. It handles expansion and contraction well.
13. Will installation disrupt my business?
Most installations are completed with minimal disruption. We coordinate with clients to reduce downtime as much as possible.
14. Do you serve areas outside High Point?
Yes. We also serve Greensboro, Winston-Salem, Kernersville, and surrounding communities across the Triad.
15. How do I request a quote?
Contact us by phone or online form. We’ll schedule an on-site inspection and provide a clear, customized estimate.
16. Why is it recommended for NC properties?
It provides reliable protection against storms, sun, and seasonal temperature shifts while remaining cost-effective for flat-roof commercial structures.
17. Are there any drawbacks?
- Torch-applied systems require skilled installation
- Seams may need periodic inspection
- It’s heavier than single-ply alternatives
18. How does it compare to other roofing systems?
- TPO/PVC: More flexible, but less durable under foot traffic
- BUR: More complex and layered, but harder to maintain
- Metal: Longer lifespan, but not ideal for flat roofs
19. Can it be installed over an existing roof?
In many cases, yes. A proper inspection will determine whether an overlay is suitable.
20. How do I choose the right contractor?
Look for a team with:
- Specialized experience in modified bitumen
- Licensed and insured professionals
- Local expertise
- Proven track record in commercial projects
