The Holthaus story
A Legacy of Roofing
Relationships built on trust.
Respect that is earned.
A Name That You Know
At Holthaus Roofing, we believe a roof is more than just protection—it’s peace of mind. As a family-owned business serving Central and Western Illinois since 1990, we’ve spent over 30 years earning a reputation for quality, trust, and expertise.
Founded by Jim Holthaus, now owned and led by Jim’s Grandson Nick and Angie Orwig, we bring generations of knowledge and a commitment to doing the job right the first time.
“Craig and his crew were great and professional especially after dealing with an insurance company. All of the workers were courteous and efficient. Great job.”

Embracing Environmental Sustainability
We care for the environment just like we care for your roof. We’re committed to reducing, reusing, and recycling every step of the way.
We measure and customize each roof to lessen excess materials.
Duro-Last recycles their scrap materials.
Duro-Last is a highly reflective and sustainable roofing membrane.
Duro-Last has low heat transfer properties so customers improve their building energy efficiency and carbon footprint.
The shingles we remove are ground up and used to make asphalt paving materials. The next time you are on the highway, it might be your old roof you are driving on.
Our staff makes every effort to participate in our shop and office recycling programs. It’s like your home recycling program, except on a much grander scale!
