Historical Property in Ellensburg, WA

The Northern Pacific Depot in Ellensburg, Washington had an original slate roof built in 1910 that was in a state of significant disrepair. In a climate known for significant freeze-thaw cycles and strong winds that reach in excess of 70 mph the not-for-profit group heading the project, Friends of the Northern Pacific Depot (FNPD), turned to EcoStar’s Empire Slate roofing system.

Using Empire Slate in a Manhattan Midnight color blend allowed the group to maintain the classic look of natural slate while obtaining the durability and sustainability of a synthetic. Empire Slate offered a solution that preserved the historical look of the depot with tiles weighing significantly less than their natural counterpart. The roofing system also provided peace of mind for the long-term future of the depot with a product designed to withstand extreme weather conditions such as hail, driving rain and high winds.

The train depot in Ellensburg is listed on the National Register of Historic Places for its role in the development of the Northern Pacific Railroad and was designed by architects Reed & Stern, the same team responsible for Seattle’s King Street Station (1906), Tacoma’s Union Station (1911), and New York City’s Grand Central Terminal (1913).
