Duro-Last Roofing

Metal Retrofit with Duro-Last

When you selected a metal building or metal roof, you had sound reasons. If that roof or building has been around a decade or more and is showing teenage problems, you may be thinking about therapy.

To cure your metal roof's ills and ease your mental anguish, think about Duro-Last's Retrofit System for metal roofs.

A Duro-Last roof installed by Nasi Roofing over an aging metal roof will give you a better roof than you had to originally.

Duro-Last will give you a roof that:

  • Won't rust or corrode
  • Won't demand periodic mechanical maintenance
  • Won't need maintenance of any kind for 15 years or more
  • Won't radiate your plant energy into outer space
  • Won't clack and clang every time the temperature changes
  • Won't worry you sick with leaks because a Duro-Last roof won't leak ever or cost you a penny for repairs in its 15 year warranted life

Customer Testimonial

Duro-Last roof

"After considering other roofing companies, we chose Nasi Roofing, LLC because of your professionalism from proposal to factory representation follow up after the job. The proposal booklet and information provided gave us all the information we needed. The working crew was efficient and seemed to work well together, cleaning up the job site each day and not hindering the flow of our restaurant business or our drive up service. In a timely fashion the representative from the factory came to assess the work done, and gave us the confidence that the job had been done professionally and the warranty would be issued. The building seems quieter and is holding the heat better than it has in the colder months. We think this can be attributed to the new roof and added insulation, and will be interested to see if this makes a difference in our winter heat bill. We are very pleased, with the job done and comfortable with the 15 year warranty."
