A-1 Extends - Roof Repair and Maintenance Services 

We are dedicated to stopping small problems before they become larger ones- helping to maximize the life of the existing roof system.  When we visit a commercial, industrial, or multi-family building for a scheduled inspection we look for a broad range of potential problem. 

Commercial roofing maintenance programs are designed to help you get the maximum life out of an existing roof system. Maintenance is so critical to the upkeep of a roof system that many manufacturers require maintenance two times a year by a certified roofing contractor, in order to keep warranties valid.

At A-1 Roofing Company, we help commercial, industrial and multi-family property owners throughout the Chicago metro area maintain and repair their roofing systems. Our maintenance program is designed to meet the standards required by many roofing manufacturers to maintain warranties on their roof systems.

Contact us to learn more about our commercial roof repair plans and roof maintenance software.


We install many different types of commercial roofing systems to meet the needs of businesses throughout the Chicago metro area:

Built-up Roof Systems

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.

EPDM Roof Systems

EPDM (Ethylene Propylene Diene Monomer) is a widely used roofing material that is known for its durability and installation ease.

Modified Bitumen Roof Systems

Known to be tough and durable, modified bitumen roofing systems are designed to withstand harsh weather conditions.

White Membrane Roof Systems

More and more builders are turning to white membrane roof systems to reduce energy costs. Building owners save money, improve the environment and contribute to a healthy city.

Metal Roof Systems

Metal roof systems are best known for their distinctive look. Many architects and developers choose them because they are energy efficient, environmentally friendly and long lasting, and their distinctive appearance.

Green/Environmentally Friendly Roof Systems

Dark colored asphalt roads and tar roofs attract the sun’s heat and are often responsible for the urban “heat island” effect found in cities like Chicago, but advances in roofing technology have found ways to beat the heat.
