2020 Edge-To-Edge & Deck-to-Sky Award

The Crivitz High School administration noticed their utility bills continually rising while they struggled to maintain temperatures throughout the building. The new roof increased the efficiency substantially.

Roofing started with a complete tear-off and then installed tapered Duro-Guard® ISO insulation, staggering the joints to help reduce thermal loss issues. Duro-Tuff® 60 mil membrane was then mechanically fastened over the insulation, and custom-fabricated curbs and stacks helped their crew keep pace with the tight timeline. Finally, EXCEPTIONAL® Metals 2-Piece Snap-On Compression was used along the perimeter to complete the termination.

2015 Edge-To-Edge & Deck-to-Sky Award

The Rapid River Public School campus connects multiple buildings with many different shaped and sloped roofs – requiring different roofing products and installation techniques.

The project started off with the removal of three different existing roofing systems, which filled 60 30-yard dumpsters! From there, Nasi Roofing utilized an array of Duro-Last products from Edge-to-Edge & Deck–to-Sky to complete the 140,000 square foot roof project.
