35 Years of Roofing History in Mascoutah, O'Fallon, Belleville, IL and Surrounding Areas


Since 1990, Bret Rasch Sr. and his now ex-wife, Susan, have built this business on hard work, honesty, and family values. From the very beginning, they worked side by side—Bret handling the labor while Susan managed the office—all while raising their four children.

As the business grew, so did the family involvement. After finishing school, their oldest son, Bret Rasch Jr., and middle son, Kyle, joined the company. Today, Bret Jr. oversees the metal roofing and sheet metal division, while Kyle manages flat roofing and shingle projects.



When you call our office, you'll be greeted by Susan or Megan, Bret Jr.'s wife, who are always happy to answer your questions and help schedule your project.

We believe in treating every customer like family and every home as if it were our own. That commitment to quality workmanship and personal service has been the foundation of our business for more than 35 years.

Bret Sr., Run This Business, Start to Finish


An Owner-Operated Roofer Stays Accountable in Ways a National Chain Cannot

Bret Rasch doesn't manage from an office. He's on job sites, talking with customers, reviewing work in progress, and making decisions in real time. Every project that carries the St. Clair Aluminum Sheet Metal name has his direct involvement — from the first look at a roof to the final walkthrough. That's not a sales line. It's how the business has run since 1990, and it's the reason customers in Mascoutah and the surrounding communities keep calling back.

Bret built a family-operated business because he believes the owner-run model produces better work. When the person who owns the company shows up to your property, the standard for what's acceptable changes. There's no regional manager to call, no franchise contract to hide behind, and no crew cycling through from a national dispatch center. The team that does your job answers to the same community you live in — and that keeps the work honest.
