In built-up roofing systems (often called “tar and gravel” or “asphalt and gravel” roofs), redundancy is the key to making a strong and lasting roof. At A-1 Roofing Co., we place layer on layer of coal tar pitch or asphalt, alternated with plies of reinforcing felts. The overlapping layers ensure that no moisture gets through.

As experienced roofing professionals, we install built-up roof systems on commercial and industrial properties throughout the greater Chicago area. We tailor built-up roofing systems to product specifications and budgets. Customers choose three, four or even five ply roofs according to their needs and budgets. Each layer creates added resistance to water and weather.

Our customers can also choose hybrid systems that combine built up roof membranes with one, two or three plies, and a modified bitumen membrane cap sheet.

At A-1 Roofing Co, we are approved to install these asphalt and tar and gravel built-up roof systems:

• Johns Manville
• GAF
• Firestone
• Garland
• Durapax

As a cost-effective and low-maintenance roofing option, built-up roof systems are the roof of choice among big box retail stores. Roofing professionals at A-1 have extensive experience installing them on retail centers throughout Chicago.

For customers considering built-up roof systems on existing structures, the impact of installation on the business is important. We can work with your schedule, completing work quickly and effectively. Doing things right the first time is our goal. By implementing quality workmanship and following guidelines set by manufacturers’ standards, we install roofs that last longer and require fewer repairs in the future.
