Klemm Exteriors is a family-owned and operated company built on decades of experience, craftsmanship, and trust. Formerly known as G. Klemm Roofing, our journey began in 1994 when Gerry Klemm founded the business with a simple mission—to provide homeowners with honest, high-quality roofing solutions. With a commitment to professionalism and integrity, Gerry established a reputation as the go-to expert for residential roofing and repairs in the Fox Valley and surrounding communities.

Gerry’s passion for roofing started long before he opened his own business. He learned the trade from his father in the late 1960s and spent years gaining hands-on experience across the construction industry. From working in the flat roofing union to serving as a superintendent for a custom home builder, he honed his expertise before taking the leap to start G. Klemm Roofing. His goal was clear: to raise the standard in the roofing industry by providing top-tier craftsmanship and ensuring that no repair was too small.

Over the years, our company became known for solving roofing challenges that others couldn’t. We built a strong team of dedicated employees and skilled craftsmen, always putting quality and customer satisfaction first. As the industry evolved, so did we—expanding our knowledge, refining our techniques, and staying ahead of industry best practices.

Now, longtime employee Jeff Rosier has taken over the business, ushering in the next chapter as Klemm Exteriors. While our name has changed, our values remain the same. Jeff is committed to continuing our legacy of exceptional service while expanding our offerings beyond roofing to include siding, gutters, skylights, and complete exterior solutions. With this transition, we’re excited to grow and provide homeowners with even more ways to protect and enhance their homes.
