From Our Website

The unique formulation of Duro-Last Roofing Systems delivers long-term value and peace of mind. Two differentiators Duro-Last offers are a high-quality reinforcement scrim and thickness above scrim. 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 roofing, providing complete roofing services. We have the flexibility to meet aggressive schedules without interruptions during installation and provide the highest level of quality so your roof will remain leak proof for years to come.


A Duro-Last roof is not like most other single-ply roofs. Because it is prefabricated in a factory to reduce seams by up to 85 percent, it fits like a glove over your building's roof deck. Properly installed, it may never need repairing. When it does, though, avoid using your own facilities crew to make repairs on a Duro-Last roof. Keep the warranty intact by letting us complete the repair for you. Not all PVC roofing responds equally well to chemical solvents or heat seaming, so repairs must be handled carefully.


During a commercial roof inspection, we evaluate your entire roofing system and all the components associated with it. Early detection of possible issues can save you money and add years to the life of your roof. You should review your roof regularly, but in years 10, 15, 20 and 25 your roof must be inspected by Duro-Last. Your roof must be inspected by Duro-Last two years prior to your warranty expiration.


I would like to say thank you for coming to my building as quickly as you did so I could get my shop up and running. The bid and the work was done promptly-- even with the horrible weather. It was a pleasure to deal with you, and I will recommend you to anyone looking for a new roof. Your staff was courteous and completed my project in a timely and professional manner. I would like to thank you and your staff for doing such a great job with my new Duro-Last Roof. You and your company have my highest recommendation.


The value of customer service with the frequent inspections paralleled with the craftsmanship of work was unmatched in the Superior, WI area for flat roofs. The installation of the roof was excellent as we had no interruptions in work and the work area was always kept clean. The workers were very cooperative with following our safety guidelines and expressing their course of action to ensure our satisfaction. We would be glad to be on your reference list and open to any questions that potential customers may have.
