Bitumen Roof System Contractor

Known to be tough and durable, modified bitumen roofing systems are designed to withstand harsh weather conditions. These membrane roofs were introduced into the market in the 1970s and are found on many commercial and industrial buildings throughout the United States, Canada and Europe. Located in Elk Grove Village, in the Chicagoland area, the professionals at A-1 Roofing Co. are experienced installers of modified bitumen roof systems. We are approved applicators of these roof systems and other membrane roofing from most leading manufacturers:
  • Johns Manville
  • Soprema
  • GAF
  • Firestone
  • Derbigum
  • Siplast
  • Tremco
  • Garland
When it comes to application methods, customers who choose modified bitumen roofs have options. Depending on their needs, modified bitumen roof systems may be installed by the torch-application method, “hot-mopped” like built up roof systems or applied with adhesives. Some modified bitumen roof manufacturers have also introduced self-adhering sheets, which cause the roofing membrane to adhere itself as it is rolled into place.
