New Commercial
Roof Installers

Is it time for a new roof?

Every commercial roof has a life cycle and there comes a point in time when it makes sense to stop repairing and replace instead.

Leaving a damaged or rundown roof on your commercial property can increase the risk of water damage, pest infestation, and other forms of damage. The cost of repairing that alongside the replacement fees for your roof will add up in a hurry. Skip the hassle; contact commercial roof installers for the service you need.

We will assist you through every phase of your roofing project, from the planning phase through the installation and well beyond. Nasi Roofing takes a holistic approach to commercial roofing installation, providing complete roofing services.

Award-Winning Projects

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.
