Modified Bitumen
Built for durability and multi-layer protection.
Modified bitumen is a time-tested roofing system engineered for strength and layered protection. Designed for low-slope commercial buildings, it combines asphalt with reinforced materials to create a durable membrane that performs well under foot traffic and mechanical stress. Modified bitumen is often the right solution for buildings that require enhanced puncture resistance and dependable long-term waterproofing.

Installed for strength and long-term protection.
Installation follows a structured process to ensure proper adhesion, seam integrity, and layered protection.
Modified bitumen is an asphalt-based roofing system reinforced with polymers for added strength and flexibility. It is commonly installed in multiple layers for durability on low-slope commercial roofs.
With proper installation and maintenance, modified bitumen roofs typically last 20–30 years.
Yes. Many modified bitumen systems are good candidates for fluid-applied coatings if the substrate is dry and structurally sound. Coatings can extend lifespan and improve reflectivity.
Signs include recurring leaks, membrane splitting, excessive ponding, and widespread surface deterioration. A professional evaluation determines the appropriate next step.
Modified Bitumen Roofing FAQs
What is modified bitumen roofing?
Modified bitumen is a multi-ply asphaltic membrane system that layers reinforced sheets for excellent puncture resistance and reliable waterproofing on low-slope commercial roofs.
How long does a modified bitumen roof last?
A modified bitumen roof typically lasts 20 to 30 years depending on the number of plies, quality of installation, and ongoing maintenance.
When is modified bitumen the right choice?
It's a strong option for roofs with heavy foot traffic or where multi-layer redundancy is valued for extra protection. We'll assess your building's use and exposure to confirm it's the best fit.
