Minnesota State Capitol Project

Roofing history was created when the architectural firm of Miller-Dunwiddie along with Minnesota Historical Preservation groups reviewed original Capitol building drawings to recreate walking plaza decks used in the early years of the Capitol building.

Specialized roofing required custom-made colored paver stones by Wausau Tile of Wisconsin to create a beautiful plaza deck system over a modern EPDM "Carlisle" roof system.

Another challenge was reroofing the section below the Quadriga or "Golden Horses". The statue group was craned in one piece off the building to be gilded with gold plating. Dalco used special roofing materials prior to the "horses" returning to their permanent base on the roof.

Challenges also arose after all original materials were removed to discover asbestos containing roofing. A full abatement procedure was used by specially trained Dalco Roofing personnel on portions of the Capitol roofs.
