Axiom Division 7 is a full-scope roofing and waterproofing contractor passionate about providing our customers with the highest quality work and customer service. 

We set out to disrupt the industry and challenge the very notion of what people think a roofer can be. To accomplish this, we place a heavy value on both knowledge and communication.


Great people are a key to our success – that is why we place a heavy emphasis on continuing education for all of our employees. Education keeps us on the cutting edge of roofing and waterproofing technology, and enables us to offer our customers the very best in materials and service.

We offer design/build and value-engineering services for nearly every commercial and industrial low-slope roofing application or system.


We work very closely with our customers to determine the most cost-effective solution for a total system roof membrane assembly across a broad variety of commercial construction projects.

With 25 years of experience, we know our industry inside and out. This has allowed us to create a high-caliber product backed up by attention to detail and superior customer service – and resulted in hundreds of satisfied—and dry—customers.

We believe in providing our customers and contractors with the very best in roofing and waterproofing solutions, this is the Axiom Way. We’ve made it our mission to live up to our core values of honesty, loyalty, superior installations, and relentless customer service.


Who We Are:

In the winter of 2007, Tim Koetje embarked on a journey to  build a low slope roofing company that would complement their highly successful architectural metals side of the business. With the help of Jeremy Parriera and Mark Maas, Axiom Division 7 was born.

Today, Tim, Jeremy and the team have grown Axiom Division 7 into a company that currently operates 4 offices across the state of Washington.


Never ones to settle for status quo, Axiom Division 7 and its family of companies are determined to continue to grow their company, doing things the Axiom Way, putting their people and their customers above everything else.
