Our Legacy in the Pacific Northwest

Founded in 2004, Summit Slate Commercial was established to solve a critical issue in the industrial sector: premature flat roof failure due to the unique moisture conditions of the Pacific Northwest.

Over the years, we have protected over 2.4 million square feet of commercial property. Our commitment to technological integration led to the development of our ITMS-4 thermal scanning protocol, ensuring that every TPO and EPDM installation we perform is backed by hard diagnostic data.

We believe in transparency, structural integrity, and building systems that outlast their warranties.
