Durable Flat Roof Protection
For flat and low-slope roofs, modified bitumen roofing offers a time-tested solution that delivers excellent durability, weather resistance, and long-term performance. At Green Group Roofing, we specialize in installing, repairing, and maintaining modified bitumen roofing systems for both residential and light commercial properties.
If you’re looking for a flat roofing system that balances cost, longevity, and proven protection, modified bitumen may be the perfect fit for your home or building.
What Is Modified Bitumen Roofing?
Modified bitumen is an advanced asphalt-based roofing system reinforced with polymer modifiers that improve flexibility, strength, and weather resistance. It’s installed as rolled sheets that are typically heat-welded, cold-adhered, or self-adhered to create a durable, watertight membrane.
This type of roofing combines the reliability of traditional built-up roofing with modern materials that offer superior flexibility and UV resistance. Which makes it ideal for flat and low-slope roofs that face constant exposure to sun, standing water, and temperature swings.
Benefits of Modified Bitumen Roofing
Modified bitumen offers several key advantages for property owners:
Excellent Durability
Modified bitumen is engineered to handle the challenges of flat roofing, including heavy rains, ponding water, snow accumulation, and extreme temperature changes. Its multi-layer construction makes it highly resistant to cracking, splitting, and punctures.
Long Service Life
When properly installed and maintained, modified bitumen roofs typically provide 20 to 30 years of reliable performance, often outlasting many alternative flat roofing materials.
Superior Waterproofing
The continuous membrane design creates a seamless, watertight barrier that effectively resists leaks and water infiltration, even on roofs with complex layouts or rooftop equipment.
UV and Weather Resistance
Modified bitumen systems are designed to withstand prolonged UV exposure, which helps protect the membrane from premature aging and breakdown.
Low Maintenance
While all flat roofs benefit from routine inspections, modified bitumen systems require minimal maintenance compared to some other flat roofing options.
