Modified Bitumen

Modified Bitumen Roofing for Demanding Low-Slope Roofs

Modified bitumen is a multi-layer asphalt-based roofing system that performs well on complex low-slope roofs. Modern Day Roofing installs and repairs modified bitumen systems for commercial and residential properties in Southwest Virginia.

Why Modified Bitumen Is Still Used

Modified bitumen handles foot traffic, complex details, and Virginia's temperature swings well when the system is installed correctly.

• Multi-layer waterproof protection
• Good puncture resistance
• Strong choice around many penetrations
• Reliable performance on certain low-slope roof designs

Repair, Recover, or Replace

We evaluate membrane condition, seams, flashings, drainage, and substrate moisture before recommending a plan. Some modified bitumen roofs can be repaired or coated, while others need replacement.

Built Around Drainage

Flat roofs fail faster when water sits. We look at scuppers, drains, slope, and ponding areas as part of every modified bitumen project.
