Roofing is in our Blood.

Tommy Bonner, owner of KAT Exteriors, started roofing the year he got his driver’s license. His uncle had a roofing company and Tommy took a position with him. Today, Tommy’s experience in roofing and home exterior construction shines through in the top quality craftsmanship you should expect from KAT Exteriors.

We Follow Best Practices in Roofing Restoration and Installation

KAT Exteriors makes sure that what goes on your roof stands up well to the brutal conditions that drift into our community from Lake Michigan.  KAT Exteriors specializes in preparing for, or repairing your property from the notorious Chicago winds and winters. Your roof is protecting your most important investment, and literally the “head” of your household. Be sure to protect your biggest asset. 

Roofs are tough but they don’t last forever. If you are experiencing leaks, mold, mildew, or other roof-related problems, contact Chicagoland’s roof rescue team at KAT Exteriors.

Like your roof, siding protects your property from the ravages of time and the elements of Mother Nature.  Let us rejuvenate your home with great looking siding.


Like it sounds, fascia is the facing along your roof eaves. Fascia is critically important to proper roof and gutter functioning. KAT Exteriors can add years of life to your home.  


Your insurance is interested in making sure your new roof is fixed with the right materials and craftsmanship. The funds we help you claim will accomplish your restoration needs.

Great Products & Fine Workmanship

KAT Exteriors knows how to handle a range of roofing materials and uses some of the most outstanding materials in the market – Certainteed, IKO, Malarkey, Norman Rockwell siding by KP Vinyl Siding and Royal Crest Siding. KAT Exteriors is fully licensed, insured and certified. 

Free Property Inspections

KAT Exteriors knows the insurance claims process well and can help you get the roof or siding restoration work you need in the aftermath of unexpected weather-related damages or other unexpected conditions. We’ll inspect your roof and meet the insurance company’s inspector to help them understand the full extent of your needs. We work hard so you only have to pay your deductible.
