For more than 30 years, the Nosak name has stood for uncompromising quality in historical preservation. Bringing the greatness out of Tulsa is our specialty and our craftsmanship is showcased on some of the state’s most distinguished architectural treasures; The Harwelden Mansion, The Governor’s Mansion, The Skelly Mansion, The Hilti Mansion, and St. Francis Xavier’s Church.
Our company specializes in historical Ludowicci tile and Vermont slate—materials renowned for their integrity, longevity, and timeless appeal. Every project is approached with passion, blending proven, old-world techniques with the precision of modern methods to deliver results that honor history and ensure lasting performance.
Known to endure for decades—and, in some cases, centuries—these materials allow us to restore and preserve roofs that will protect and inspire for generations. At times, this means replacing an entire roof system: carefully removing the original tile and slate, repairing the decking and underlayment beneath, and reinstalling the same historical materials. This careful process not only restores the structure but also showcases the unmatched durability and enduring value of the materials we work with.
Our philosophy is simple: repair when possible, replace when necessary, and discard never —because history is worth keeping. We focus on preserving original character while ensuring every roof is built to perform for decades to come.
The Nosak legacy is one of excellence, heritage, passion, and trust—protecting the past, honoring the materials, and keeping the art of true craftsmanship alive. Since our start in 1991, we have spent decades restoring and protecting the some of Tulsa’s most iconic tile and slate roofs. In a time when its unclear who to trust, we stand apart—this has been our craft from the very beginning. We are still here, and there is only one name in Tulsa for true tile and slate roofing: Nosak.
