Built-Up Bitumen Roofing: A Proven Flat Roof Solution
When it comes to durable, time-tested roofing for flat and low-slope buildings, few systems compare to built-up bitumen roofing. At The Flat Roof Guys, we specialize in flat roof solutions that stand up to the harshest weather, and built-up roofing (BUR) is one of our go-to systems for commercial and residential clients alike.

What Is Built-Up Bitumen Roofing?
Built-up roofing consists of multiple layers of asphalt-based sheets, typically reinforced with fiberglass or organic materials. These layers are “built up” on-site using hot or cold adhesives, then finished with a protective surface like gravel or a reflective cap sheet. The result? A thick, multi-ply membrane that offers superior waterproofing and exceptional durability.
Why Choose Built-Up Roofing?
Here’s why BUR continues to be a trusted choice for flat roofs:
-
Proven Performance: This system has been used for over a century. It’s battle-tested and reliable in both hot and cold climates.
-
Superior Waterproofing: Multiple layers provide redundancy, reducing the risk of leaks or water intrusion.
-
UV & Fire Resistance: With the right cap sheet or gravel finish, built-up roofs reflect UV rays and can even be fire-rated.
-
Low Maintenance: Once installed, BUR systems require very little upkeep beyond occasional inspections.

Best Applications
Built-up roofing is ideal for:
-
Commercial buildings
-
