Modified Bitumen Roofs

Crown Roofing Chicagoland Modified Bitumen Roof

Modified Bitumen Roofs are an excellent alternative for Residential Buildings and Commercial Properties in the Chicagoland area. A Modified Bitumen Roof is an extremely economical and flexible roofing system for low-slope or flat roofs in Chicagoland.

Modified Bitumen Roofs are one of the oldest of the “modern” roofing methods, but the Modified Bitumen Roof has certainly been time-tested. With new advances in technology, the Modified Bitumen Roof has become a long-lasting and safe roofing material for single and multi-family dwellings in the Chicagoland area.

Crown Roofing would love to come out to your Chicagoland Residential, Commercial or Industrial property to give you a free estimate for a Modified Bitumen Roof. Contact Us today for a free estimate with an experienced Roofing professional.

We will install a GAF white granulated Modified Bitumen membrane, which is tough and resilient. It’s a durable membrane that will withstand the fluctuating Chicagoland climate.

During installation, the Modified Bitumen membrane is torched down and the seams will be heat-welded. The result is a continuous roof membrane that demonstrates revolutionary waterproofing characteristics, extreme heat resistance, and flexibility in low temperatures.

At Crown Roofing & Masonry we are fueled by our commitment to excellence and always go the extra mile to make sure our clients are completely satisfied with our Roofing and Masonry work. Our customer service and attention to detail is what separates us from other Chicagoland Roofing and Masonry companies.
