Built-Up Roof System

For a proven, time-tested roofing solution, consider having Langer install a Built-Up Roofing system (BUR) on your property. More than just a roof, a BUR is an investment in your property's longevity and resilience. With roots dating back to the mid-1800s, BURs offer several performance advantages, including exceptional tensile strength, redundancy, flexibility, and impact resistance.


Combined with a modified bitumen or hybrid roof, you can significantly extend your roof's lifespan and minimize maintenance needs. Conventional bituminous built-up roofing membranes have been a staple in the roofing industry for over 150 years, making them a trusted choice in today's market.

Despite their high-quality performance, Built-Up Roofs are surprisingly cost-effective compared to lower-quality roofing systems. When installed by a Langer professional, they provide superior water resistance, long-term durability, and cost-efficient maintenance. Easy to install and exceptionally reliable, most BURs last for at least 20 years, with some lasting up to 40 years – offering a "set it and forget it" roofing solution.


Built-Up Roofs are designed to withstand Wisconsin's diverse weather conditions, minimizing movement with their high tensile strength and reducing the risk of fracturing. For a quality roofing system that will endure the test of time, contact us today!

This system, utilized in the U.S. since the 1970s, boasts exceptional durability, weather resistance, and minimal upkeep requirements. While there may be a slightly higher initial cost, the investment pays off over time due to the minimal attention required by Mod. Bit. roofing systems.


Our Langer professionals offer hot mop, cold adhesive, or heat welding applications tailored to your specific requirements. As a hybrid application, Mod. Bit. roofing is resilient in any Wisconsin weather condition, with reduced risks of cracking and splitting. Various cap sheet color options are available.
