About Us

From design and repair to our technology and maintenance program,
A-1 Roofing Company sets the standard for high-quality roofing solutions.


Commercial Roofing Services

At A-1 Roofing Company, we provide a full range of commercial roofing services. From the design and installation of a commercial roofing system to regular maintenance or emergency roof repairs, we emphasize quality workmanship and responsiveness to our customers’ needs. We offer:

Design and Installation

We design and install roofing systems on new construction and existing commercial and industrial structures, tailoring our approach to project specifications and blueprints.


We offer a maintenance program and specialized software designed to help you get the maximum use out of your roof system. This aligns to studies showing that regular maintenance extends the life of your roof and reduces long-term costs.


We offer storm damage assessment and repair of roofing problems that can lead to leaks and water damage.

Sheet Metal Shop

We also incorporate an architectural sheet metal shop, which enables us to fabricate roofing components to the needs of specific projects. We commonly employ 50 to 90 roofers and sheet metal workers, depending on the time of year. We make and install gutters, counterflashings, copings and other roof-related sheet metal. We also install standing seam metal roofing systems from Berridge Manufacturing, Petersen Aluminum Corp. and other manufacturers.


Over a Century of Roofing Excellence

For three generations, customers in Chicago and greater Illinois have turned to A-1 Roofing Co. for quality installation, maintenance and repair of commercial roofing systems.

Family leadership has helped us stay true to the values on which our grandfather founded the company. Our president is Mitchell (Mitch) Rabin, a graduate of the University of Illinois and a Certified Public Accountant. He has been involved with the company since 1980. Vice President David Rabin is also a graduate of the University of Illinois with a C.PA. degree, and has been with A-1 Roofing since 1986.

We are active in the professional community, and our active role helps keep us updated on the latest technology and installation techniques. We are members of the National Roofing Contractors Association (NRCA). We are also members of the Chicago Roofing Contractors Association (CRCA), and Mitch Rabin sat on the Board of Directors for the Association for five years.

We are excited to have reached a milestone that not many companies have achieved. We have survived recessions, a devastating fire in 1990 and a six-inch flood in our offices in 1991, as well as many other obstacles over the years. Our continued growth is a testament to the strength of our resolve and the commitment we have made to quality workmanship. We thank our customers, suppliers, professionals and all the others that have helped us grow our business for a hundred years. Here’s to a hundred more!


Continued Growth

A-1 Roofing Co. continues to grow with Chicago by keeping up with the improved technology and installation methods that have transformed the roofing industry. We have also implemented digitized plan review and paperless estimating, which helped us become a greener and more efficient company.

But some things remain the same. We continue the dedication to quality product, professional workmanship, and personal attention that has been our hallmark since 1910.
