Built-Up & Modified Bitumen Roof Restoration
Built-up (BUR) and modified bitumen systems have protected flat and low-slope commercial buildings for decades. Known for their durability and multi-layered asphalt construction, they hold up well over time, but they aren’t immune to aging, cracking, and water intrusion. We offer expert restoration for built-up and modified bitumen roofs that eliminates leaks, reinforces the surface, and extends your roof’s life, without the disruption or cost of a full tear-off.
What Are Built-Up & Modified Bitumen Roofs?
Built-Up Roofing (BUR)
Often called “tar and gravel” roofs, BUR alternates layers of asphalt and reinforcing fabric, topped with gravel or a reflective coating for strength and longevity.
Modified Bitumen
Asphalt-based membranes enhanced with rubber or plastic modifiers for added flexibility, rolled out and heat-sealed to resist foot traffic and temperature extremes.
Benefits of Restoring Asphalt-Based Roofing Systems
Restoration can add 10–15 years of performance at 30–50% less than a full replacement.
Save Thousands Over Replacement. Restoration typically costs 30–50% less than a full replacement.
Improve Energy Efficiency. Reflective coatings reduce roof temperatures and lower cooling bills.
Extend Roof Lifespan. Add up to 15 years of serviceable life without removing the original system.
Minimize Business Disruption. No tear-off means less noise, mess, and downtime.
Strengthen Leak Resistance. We eliminate active leaks and prevent future water intrusion.
