Modified Bitumen FAQ

Answers to frequently asked questions about modified bitumen for Chicagoland properties.

What is modified bitumen roofing?

Modified bitumen is an evolution of built-up roofing that uses polymer-modified asphalt membranes. It can be torch-applied, cold-applied, or self-adhered, providing excellent waterproofing for low-slope residential and commercial roofs.

Is modified bitumen good for Illinois flat roofs?

Yes, modified bitumen performs well in Illinois. The flexible membrane handles temperature swings without cracking, and multi-layer systems provide redundant waterproofing. It's a popular choice for low-slope roofs on additions, porches, and commercial buildings.

Modified bitumen typically lasts 20-30 years with proper installation and maintenance. Regular inspections and prompt repair of any punctures or seam issues help maximize lifespan in Chicagoland weather.
