The Holthaus story

A Legacy of Roofing

Relationships built on trust.
Respect that is earned.

A Name That You Know

We are a family business founded by Jim Holthaus in 1990. We’ve been serving Central and Western Illinois for over 25 years.  Our company was passed down to Jim’s grandson, Nick Holthaus, in 2004. Together Nick and his wife, Angie, operate the award-winning Holthaus Companies, Inc. Roofing Contractors.

Our customers are like family, and we understand the value of family. You can depend on us to deliver exceptional quality, expansive knowledge, and experienced service.

CertainTeed ShingleMaster

As a CertainTeed ShingleMaster certified company, we’ve met the highest standards in the shingle roofing industry. Our specialized training and certification mean expert installation of premium CertainTeed shingles, backed by best practices and extended warranties. With Holthaus, homeowners enjoy top-tier service and the peace of mind that comes with a roof built for long-lasting quality and durability.

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!

He is polite, detailed, appreciates people’s time, is quick to respond to your emails/phone calls etc. The new roof and large gutters make our building look new. They use top quality materials and use finishing touches that show their professionalism.”
